Don’t Want to Spring for a Hot Tub? Try a Stock Tank Pool

Taking the plunge in troughs originally used to feed farm animals.

If you happened to find yourself scouring the internet in search of an Intex inflatable pool last spring, only to come up empty-handed, you had company. According to Sabeena Hickman, the president and chief executive of the Pool & Hot Tub Alliance, pool sales skyrocketed as Americans faced a quarantined season at home.

Based on permit numbers, 94,000 new in-ground residential pools will be built by the close of 2020, an increase of almost 21 percent from 2019. (The demand for hot tubs is more appreciable: Numbers are up 400 percent this year from last, according to Ms. Hickman, and tubs are largely backlogged six months.)

A dearth of conventional pools has brought a new type of soaking apparatus to the forefront, aided by social media: the stock tank pool. Crafted from a galvanized metal tank traditionally used as a feed trough for farm animals, a stock tank pool can be assembled in a day with a few D.I.Y. items that can be found at most hardware stores. With cooler weather approaching, and states headed toward probable lockdowns, some water lovers are opting for the next best thing: the make-your-own hot tub.

According to Ben Uyeda, the designer and co-founder of HomeMade Modern, an online design source that publishes instructions for home furnishings and projects, the D.I.Y. hot tub moment has definitely arrived. Mr. Uyeda’s videos detailing how to make your own hot tub have received millions of views. His first video featured a wood-burning heater, and his second, more user-friendly iteration included a heater made out of a propane tank.

“Every time we’ve done a hot tub-related project like this — in a scrappy vein — the thumbnails for it have just generated massive amounts of clicks,” he said.

The popularity of the hot tub videos reflects both the zeitgeist and this particular moment of the pandemic, Mr. Uyeda said. “You start with the essentials, and then you add things for efficiency.” He said that people are now more likely to take up D.I.Y. projects that are lifestyle upgrades, unlike early in the pandemic, when they sought remedies for immediate problems.

For Andrew Rowland, 30, and Caitlin Wallace-Rowland, 29, who live in New Orleans, the recent addition of a stock tank hot tub was a luxury that followed a long list of home renovations. “We kind of renovated our entire front and backyards, and then we were sort of running out of activities,” Ms. Wallace-Rowland said. After taking numerous weekend trips to the Mississippi coast so that their 2-year-old daughter, Laurel, could swim, they decided a pool was the next project to tackle.

In September, they fashioned what is now their hot tub out of a galvanized stock tank, with a heating apparatus configured from a propane tank. Ms. Wallace-Rowland, an artist and textile designer, planned where the pool would go and designed a landscaping scheme for it. Mr. Rowland, a director of system operations for a charter school, assumed the task of building the actual tub, which he described as “a very peaceful install.” The result is a tub that suits their petite yard and allows for year-round enjoyment.

Sara Haddox, 34, installed a stock tank hot tub at her home in Llano, Tex., which she largely rents out on Airbnb, in September, as well. “My husband went on a big hunting trip, and while he was gone, I was bored, so I decided to go ahead and bring the hot tub idea to life,” Ms. Haddox said.

Calling upon her degree in construction science, Ms. Haddox, who manages her family’s rental property, created an insulated stock tank hot tub with an electric heater (rather than a propane one) so that it reaches a higher temperature and stays hotter for a longer time.

Her initial inspiration, she said, came from Pinterest and Instagram, where people had posted photos of stock tank tubs in stunning settings. “I just loved these shots of these, like, isolated tubs, where you could just, you know, be in nature and just see forever and just enjoy being outside in a new way,” she said. “Those pictures really sunk in.”

She had considered building a tub for several years, she said, but the events of 2020 forced her hand. The result is a tub that has drawn attention to her family’s Airbnb, which appears on Instagram as @houseonthellano. Although visitors may not be able to enjoy the nearby ice-cold Llano River in winter, or the city’s restaurants and museums, they can enjoy the property’s fire pit and, now, its winter-friendly hot tub.

“We needed to offer a more complete vacation package,” Ms. Haddox said. Her homemade hot tub helped.

A hot tub began as a hot weather pool project for E. Spencer Schubert. A sculptor in Kansas City, Mo., Mr. Schubert, 43, decided to add a stock tank pool to his property at the start of the pandemic as a way to make up for his family’s lost summer. He and his wife, Ryann, 42, rented an excavator and installed an eight-foot stock tank swimming pool with surrounding decking. As for converting the pool into a hot tub, that was “just the next iteration,” Mr. Schubert said.

The stock tank is now heated with a propane heater, and Mr. Schubert has converted the yard into a multi-season oasis, with a fire pit and “circus lights.” “During the reasonable temperature part of the year, the place of the house that we use the most is the backyard,” he said.

Although the temperature of the tub reaches about 90 degrees, Mr. Schubert said that Missouri’s cold winters will likely limit their use of it in February. Nonetheless, the D.I.Y. hot tub will lengthen the life of the Schubert family’s pool season.

The stock tank pool rose in popularity early in the pandemic, said Jovana Johnson and Janice Luna, the owners of H20 Tank Avenue in Santa Clarita, Calif., which delivers stock tanks to customers in that state, Arizona and Nevada. When they started their company in May, Ms. Johnson and Ms. Luna immediately sold all of the 27 tanks they had ordered.

“We said: ‘OK, you know what? I think we’re going to order another set of tanks, but this time we were going to go distributor status,’” Ms. Johnson said. She and Ms. Luna placed their second order for 150 stock tanks, many of which sold on pre-order via Instagram.

Now that the season has changed, they see potential in the market for tubs with heating options and have added a “tankuzzi” service as a way to extend the stock pool season. They sell a tankless, propane heater that increases the temperature of the water to 105 degrees.

“We’re fortunate here in Southern California to have very mild winters,” Ms. Luna said, which she said allows customers to use their pools and tubs all year long.

Ms. Johnson pointed out that a stock tank hot tub is flexible. (“If you decide to move, you can take it with you,” she said.) A traditional hot tub can weigh over a ton and often gets left behind in a move. The aesthetic of the stock tank hot tub has developed its own unique following, too.

“It’s just a chic look,” Ms. Johnson said.

As for the rolling-up-the-shirt sleeves nature of the stock tank hot tub, Mr. Uyeda insists that building it yourself is part of the point. “It’s a homemade everything moment,” he said.


Stock Tank Hot Tubs

A lot of folks have discovered how easy and inexpensive it is to create a soaking tub using an agricultural stock tank (available from most farm-supply stores). When combined with a Chofu hot tub heater or our new electric heating system, these low-cost galvanized steel or plastic tubs make wonderful soaking tubs. They have a pleasing smooth surface, the perfect shoulder depth, and a round top rim for a comfortable arm and neck rest.


Stock Tanks Make Sense

The fact is, a lot of people prefer the simplicity of a soaking tub to a high-maintenance spa. For those who want something simple, low-cost, and functional, stock tanks are just the thing – a gift from heaven!


Advantages of Stock Tanks

  • Low Volume for Fast Heating
  • Rugged and Durable
  • Low Maintenance
  • Easy Installation
  • Lightweight, Easy to Move
  • Shoulder-Deep 23-24 in. (Bathtubs are 13-15 in. deep.)
  • Inexpensive: $100 to $150 depending on size.


Yes, It Can Be Attractive

A stock tank soaking tub doesn’t have to look crude or tacky. You can make it as attractive as you want by covering the sides with a variety of materials: wood, split bamboo, leather-grain vinyl, Sunbrella fabric, etc. (Ask us about instructions for insulating and enclosing stock tanks.) (Photo link to stock tanks with different coverings)


Perfect for the Cabin

Stock tanks used with a Chofu hot tub heater are especially practical for vacation cabins where electricity is unavailable and where a soaking tub might sit unused for months. You can easily disconnect and store a Chofu stove, leaving the stock tank outside without worry.


Easy Set-Up

  1. Cut two holes in the side to install thru-wall ports.
  2. Cut a hole in the bottom for a drain.
  3. Place the tub and heater on solid foundations to create a level surface and provide the proper elevation of tub to heater for efficient thermosiphon
  4. Connect the Chofu hot tub heater to the tub using the connecting tubes and clamps provided.

An insulating cover is desirable to keep heat in, either floating insulation or a custom-made vinyl insulating cover.


Metal stock tanks are made of electroplated galvanized steel with a glass-smooth surface. They have straight sides with lateral corrugations for strength and a 1- inch diameter rolled top rim. Vertical sides make it easy to insulate and cover. The standard depth is 23-24 in., just right for shoulder-deep water. Metal stock tanks come in either round or oblong shapes – both desirable for soaking tubs.

Plastic stock tanks are becoming increasingly popular for use as DIY hot  tubs. They’re made of UV-resistant polyethylene and range in depth from 23-24 in. Typically, the top edge has a 2″ diameter rolled rim that is very comfortable for a neck and arm rest. Plastic stock tanks are made with sloping sides with angled steps for stiffening, which makes insulating a little more difficult; however, they can be made very attractive when enclosed with wood paneling. (link to Mother Earth News article) note: Unfortunately, plastic stock tanks do not come in a 5ft diameter size. They jump from a 4½ft. x 3ft. size to 6ft diameter.


Oblong Tanks are the right size for one or two people sitting at each end with legs side by side. They use a minimal amount of water and heat up quickly. Consider metal tanks 5ft. long x 2 ft. wide, 6ft. long x 2ft. wide, or 6ft. long x 2½ft. wide.


Round Tanks are more spacious, hold more people, but also hold more water.


Does Size Matter?

Stock tanks have cozier leg-room because they don’t have a bench or foot well, but the benefit is that they have much less water to heat, fill, and drain. When choosing a tub, we recommend thinking small: a 6ft. diameter stock tank will provide plenty of leg room for four people, but a 5ft. diameter tank will also hold four people and heat up faster – although it’s cozier.

What’s the Right Depth?

People tend to think that a stock tank will not be deep enough, when, in fact, they are the perfect depth for most people. When you sit in a soaking tub, you don’t sit perfectly upright. You slouch. That said, the best depth is about shoulder high. Water up to your chin is uncomfortable and chest high is not deep enough. You also want to be able to rest your arms on the top rim or lay your neck back on the rounded rim. Most stock tank brands are 22-24 inches deep, which is just right for someone 5ft. 8in. to 6ft 2in. But what about shorter people and kids? Luckily there’s a simple solution. An inexpensive plastic lawn chair can be cut down to make a booster seat. They work great! (see photo)

Where to Get Stock Tanks

One of the best things about stock tanks is that they are available everywhere from agricultural supply stores – usually both plastic and metal stock tanks. Different regions will have different brands, some more desirable than others. (see Purchasing a Stock Tank)

How to Keep Your Garden Alive During the PDX Heat Wave

The DIY backyard hot tub quest that nearly ruined my marriage started back in May, with a text masquerading as a flex from a friend. Her husband had just purchased a ginormous stock tank to turn into a backyard swimming pool, a bulwark against the sticky COVID summer.

I was immediately consumed with equal parts envy and lust. No plastic blow-up affair for me: bring on the stock tank, with its rustic-chic air of cool.

Unfortunately, there was none to be found within a 200-mile radius. What we did have was an underused galvanized steel planter, then holding some sad bamboo, big enough for one person at a time (or maybe two little kids). My husband cleaned it out, bought a filter, and a chlorine dispenser. I took to grandly referring to it as our “soaking tub.”

But when the weather turned, so did my thoughts: I’d always wanted a backyard hot tub. We were already 85 percent of the way there. How hard could it be?

Pretty hard, it turns out, particularly when your partner refuses to click the promotional links embedded in the online tutorial to purchase the needed parts from the internet, preferring to putter around at local hardware stores in search of various spigots, hose attachments, and sealants.

But once you’ve amassed those—plus a mini tankless water heater, a propane gas cylinder, a pump/filtration system, and a drill for making holes in your tub to run the tubes through—you’re good to go.

Or so I thought. The online tutorial suggested a two-hour project, but this took the better part of four days. The first iteration was a frustrating flop, due to the off-brand pump that simulated a loud, wildly out of tune accordion. But a replacement pump did the trick. It’s virtually noiseless, and our tub now hits 102 degrees in 30-ish minutes. (We realized too late we could have gone the potentially easier, lo-fi route of heating the water via a wood-burning fire/copper coil conducting setup.)

Now we can backyard bask while stargazing to our hearts’ content. Should you try this at home? Since the pump, and the arguments, have quieted, I’d recommend it—maybe even with a tub built for two.


How to Build the Ultimate DIY Stock Tank Hot Tub

If you are thinking about building a Stock Tank Hot Tub or even a Stock Tank Pool, then you must read this article first! In this blog post we are going to discuss the pros and cons of building your own Stock Tank Hot Tub or Pool.

We’ll tell you exactly how to do it and compare it against the concrete block method that I used to build mine. If you already have your mind set on building a Stock Tank Hot Tub I will explain exactly how to build one!

A Bit of Background

At time of writing, it’s almost two years since I broke ground on my DIY Hot Tub Build. Two years on, the family and I still love it. We still use it 3-4 times a week and it was a great project to undertake.

If you have read this blog before the whole idea of it was to put all of my new found knowledge into one place. I didn’t know anything about this subject matter two years ago!

Now, I’ve just discovered that there is a type of DIY Hot Tub that I had not heard of before – Stock Tank Hot Tubs. Therefore, I thought I would do some investigating and see if I can draw up some pros and cons and conclude if it is a good idea or not.

What is a Stock Tank Hot Tub?

Let’s start with the Stock Tank. What is one of these? According to Wikipedia, “A stock tank is used to provide drinking water for animals such as cattle or horses. Stock tanks can range in size from 100 L to over 5500 L and typically are made of galvanized steel. These tanks are filled either by a pump, windpump, creek, spring, or even rely on runoff water from rain or melting snow.”

OK, so now we know what one of these is. It’s a big steel vessel that can be filled with water.

Given that it is designed to hold water, no wonder people are converting these into Hot Tubs.

What are the Drawbacks of Stock Tank Hot Tubs and Pools?

Affectionately known as “hillbilly hot tubs” these tubs can certainly be affordable and it is easy to see why I am sure they will be once again very popular this summer.

However, there are a few drawbacks.

Slime and Algae

This is of course the general problem with standing water. It is going to develop slime, algae along with lots of other bacteria. Yes, it is possible to combat this with chemicals, but as the water is standing, it makes life a lot harder.

Lack of Filtration

Filters are part of what keep our Pools and Hot Tubs looking clean, clear and inviting. They remove debris from the water. With the lack of filtration in a Stock Tub Hot Tub you are going to get a build up of debris. You are going to have to try and work a lot harder with the chemicals to keep that water clean, clear and most importantly safe.

Needs lots of Chemicals

As we have mentioned above, there is not filtration. Yes, you can do this manually with a net to get the larger particles out of the tub, but you are going to need a lot of chemicals to keep the water clean, clear and safe.

What about Rust?

Rust is going to be a problem so you are not for example going to want to drop your Chlorine tablets directly into the tub. There is no skimmer to put them in so you will need a floating device. Rust is going to be a problem and the amount of chemicals you are going to be adding to the tub is going to speed this process up.

Standing Water = Mosquitos

I guess it is inevitable. Depending of course which part of the country you are in, your standing water in the Stock Tank Hot Tub is going to attract insects and mosquitos. If, like me, you are not so affected by bites it is not a problem. My wife on the other hand, this would be a non-starter for her as she reacts so badly.

Takes Forever to heat as need a Fire first!

It is not going to be the most convenient of ventures. You need to build a fire, let it heat up before you can then heat the water. The idea of going for a “quick dip” isn’t really going to work.


I am sure that this is very much a personal preference thing, but they don’t look the comfiest. Surely, the whole idea of a Hot Tub is being able to kick back, relax, have a glass of something and let the woes of the world pass you by. Can you do this by being almost bolt upright in a Stock Tank? Not sure – I’ll let you be the judge of that.

Jets and Bubbles?

One of the big lures of the Hot Tub is the bubbles and jets that spray water around the tub creating a relaxing atmosphere. One could therefore argue, that a stock tank hot tub, without “jets and bubbles” is really just an outside bath! Yes it is possible I am sure to plumb in jets, heaters, filters and everything else. If you are going to go that far you might as well build you own in the same way I did. If you have the skills to plumb in a stock tank, you have the skills to build something a little more substantial.

What is the Alternative to a Stock Tank Hot Tub or Pool?

Build your own Hot Tub

Build your own Hot Tub

The alternative is a Concrete Block or Cinder Block pool, like the one that I have made. It will take you a little longer to build. It will cost a little more to make. It will also cost a little more to run. But, what you end up with a a PERFECT Hot Tub that rivals and arguably trumps the plastic shell type, or indeed the inflatable Hot Tubs that are available on the market.

How to build the Ultimate Stock Tank Hot Tub

In the interest of balance here, if you read the article so far you will have thought that I am against building a stock tank hot tub. So I sat down, had a couple of cold beers and thought, well, what if I came up with the ultimate design for a Stock Tank Hot Tub that addresses all the negative points above. OK, so it is not going to be a cheap as a traditional stock tank hot tub, but it will still be cheaper than a concrete block tub and arguably quicker and easier to do.

Where do I start with my ultimate Stock Tank DIY Hot Tub design?

The first thing that I wanted to do with the design is address pretty much all the cons or negative points that I have raised in the article above. Jets, heater, filtration and a pump. Add these into the mix and we have the beginnings of the ultimate DIY Stock Tank Hot Tub.

We will not have to worry about standing water, slime, algae, lack of filtration and building a fire to heat it. We’re going to build a the ultimate DIY Stock Tank Hot Tub by using the stock tank as the water vessel and then adding all the plumbing to make it a full on hot tub.

It will be cheaper than using concrete blocks. Less skills needed. No need to dig a big hole first or to worry about the capacity of the vessel to hold water – that is what its job is!

Some of the parts however have to change. The Gunite bodies which I am some enamoured with have to change as they are not suitable for this kind of build. The biggest challenge is going to be to make sure that the stock tank does not leak where we are going to cut holes for the jets and the skimmer. Nothing that a tub of epoxy resin or similar plumbing adhesive will not fix.

So first things first, let’s take a look at the Stock Tank we are going to use for this build.

The Stock Tank (to be converted into a Hot Tub)

I found one on Amazon, I’m not going to put a link as I am not an affiliate you can easily search for it. You can get one of these from anywhere. The one that I saw was roughly 6ft in diameter (1.8m) and 24″ tall (60cm). It holds approximately 340 gallons of water. This will be slightly less as we will not be right up to the top on this one. As there is no seating, we don’t need to worry that it is not quite as deep as the rest of the designs that we have.

The volume is a little bit less so we can spec down the pump and the jets if we wish. However, I like the idea of a 16 jet system with seating for 4 in this tub so I am going to specify 16 jets and a pump that can cope with this. Any Hot Tub according to BISHTA needs to have at least two drains to make sure there is adequate flow to the pump so we’ll design in 2 drains for this too. The skimmer we’ll use a regular pool skimmer. Spa Pack for the heater and pump control and also the filter to keep that water crystal clear.

Not its time to do some research on the parts needed for out DIY Stock Tank Hot Tub

Plumbing Parts

We’re a bit more used to concrete block tubs here at but we liked the idea of the challenge of designing the ultimate stock tank hot tub. We’ve already mentioned you can’t use Gunites but we did find some jet bodies that were more suitable to commercial applications, but we think will work nicely on the Stock Tank.

Being able to seal them up to the surface is going to need some form of epoxy resin around the edges of each jet, more than likely on both sides of the metal to ensure that there are no leaks. The beauty of the stock tank is that you are going to be able to see the plumbing have have comfortable access to it. If there are leaks, you can plug them with plumbers mait or more epoxy resin – both of these materials will set under water. (I’ve used them myself of my own top to repair a corner that came loose)

The pipe that we are going to use is 1″ and 1.5″. The particular jet bodies that we have found take a 1″ pipe but the filter is a 1.5″. Nothing too complicated here as we are going to use converters to take us up and down the pipe thicknesses. Remember, the pump is probably going to be a 2″ in and out so we’ll need a converter there too.

We can use the same style of drain that we have used on the concrete tubs. The reason for this is that the drains are actually designed for more of a shell-like tub which our stock tank will fall into.

The skimmer is going to need to be placed and held in place with some epoxy resin or more plumbers sealant.

Now it is time to put the plumbing diagram together. If you would like a full plumbing diagram, this is just a screen grab, you can purchase this in the shop. It also comes with a full list of parts that you need to make this work.

Get the right parts for the job and you are half way there! Don’t know what you need? Not a problem, neither did I! We can help with that too and a full set of instructions.

The Control Room

The “Control Room” setup that we are going to use for this Ultimate Stock Tank Hot Tub design, is going to be the tried and tested setup we use on all our concrete builds. It comprises of a pump, filter, blower and spa pack.

The Spa Pack controls the heating of the water as well as the filter cycle and the pumps. It’s a clever piece of kit. What it also means is that we are going to be removing some of those negative points we mentioned earlier, usually associated with stock tank Hot Tubs.

This particular setup that we have built for a customer is using only the highest quality of parts from top USA brands Balboa and Waterway. It is totally possible to replace some of the these parts with cheaper ones to bring down the cost of your Stock Tank Hot Tub.

The two gate valves are to enable you to isolate the components for changing the filter and also servicing any of the parts if you need to remove them from the system without draining your stock tank.

Time to cut some holes!

For this Ultimate Stock Tank DIY Hot Tub, we’re going to use 16 jets, 2 lower drains and a skimmer. This setup is going to replicate the setups that we have put together for many different brick and cinder block designs. The whole idea of this ultimate design is that it addresses all the questions and negative points usually associated with Stock Tank Hot Tubs.

The sides of the stock tank are obviously metal, but they are not too thick that a hole cutter cannot be used to cut the size. The exact sizes full list of parts and designs are available for you to buy from our shop.

The jet bodies are a little different that we are going to use on this stock tank hot tub. The ones that we talk about called Gunites are not suitable for this kind of build. We are still going to go with a mix of air and water to give the ultimate hot tub experience in a Stock Tank!

Secure the Jet Body In Place

Once you have the hole drilled, you are going to need to secure the body in place. Sealing it in is the most difficult part of this build. The tub itself is already water tight, that is what it is designed for. Therefore, the holes that you cut you need to ensure that you are going to seal them correctly.

You can find many examples on the internet that have hoses going into the tub from the top. These have no jets and are really just outdoor bath tubs. We want to have some proper “Hot Tub activity” in terms of jets and bubbly water.

Here is an example of a jet that has been cut into the side of the Stock Tank.

Stock Tank Jets

Stock Tank Jets

I would suggest some form of epoxy resin that can bond to both metal and the plastic. You will need the PVC pipe cement to make the joints on the regular pipework, but for each of the 16 jet bodies and the two lower drains, plus the skimmer, you need to have some form of epoxy resin to bond and seal the parts in place. Remember, these parts are designed for plastic tubs where they can be cemented in, we’re making them fit in a DIY way to a metal surface.

These are the jet bodies that you are going to need. You can see on the pictures below that the front screws off the body. This allows you to put a rubber gasket on each side of the Stock Tank, then you can screw the jet back together tightly to make the seal. This is an alternative option to glueing the body in place.

Stock Tank Hot Tub Jet Body

Stock Tank Hot Tub Jet Body

Once you have cut the holes for the lower drain, the actual drain that we use from Waterway does have a sealing ring and a losing nut to go on the back. You will be able to make a water tight seal just by tightening the nut. If it doesn’t, use some more of your epoxy resin to seal the join.

When you cut the hole for the skimmer, you need to measure the throat of the skimmer and not the face. The face needs to sit flush with the metal of the stock tank. The top of the skimmer should also sit flush with the top of the Stock tank. This will ensure that you water level is around the middle of the skimmer.

Fitting the Plumbing

Hot Tub plumbing really falls into to parts, inlet out outlet. This is going to be the same for our Ultimate Stock Tank Hot Tub.

Inlet / Inward Plumbing

This part of the plumbing is where the water is sucked into the pump. The way in which the Hot Tub pumps work is that they draw water in from one side of the wet end and then push the water out of the other. On the inward draw side of things we have the Skimmer which is going to be connected directly to two “bottom drains”  In our case, we are going to put these two drains onto the walls of the Stock Tank.

The reason that you have two drains is to make sure that the pump always has a flow of water even if one is blocked. This could damage the pump in the event this happened.

Then, we need to pass the water to the other side of the pump and the Outward Plumbing starts at the pump.

Outward Plumbing

The outward plumbing starts at the pump on the other side of the wet end. From here the water passes first through the filter, then through the spa pack where it is heated as it passes over the heating element. Then, it moves up through the jets into the tub. Therefore, your ultimate stock tank hot tub is going to be heated by the spa pack and the heater water is delivered to the tub via the jets. Simple enough to understand?

If you need the full plumbing diagrams for this build, they are available in our shop to purchase.

Making the Perfect Plumbing Joint

The first thing that you are going to do is make sure that your pipe is clean and free of any grease. The beauty of the hot tub pipe system is that if it is done correctly, it is just not going to leak. It is also not going to come loose in the future, it is there to last. Clean with some glass paper the ends of the pipe, remove any rough edges.

You then also need to clean the inside of the pipe fitting that you are going to connect. It should look all roughed up when you have cleaned it with the glass paper.

Next, you are going to need some pipe cement like this. It is not regular glue, it is special pipe cement.

Using the ball dabber that you find inside the tin, you then need to put a generous amount on the inside of the fitting that you have just cleaned. There is no need to put cement on both ends, just on the internal fitting. That will make for a clean and secure internal joint.

Push and hold the pipe and the fitting together for a few seconds. It will hold after about 5 or 6 seconds and be at full strength within 2-3 hours. This is fantastic stuff and makes for rock solid joints.

Top Tip – make all your joints at the perfect 90 degree angles – not like mine above. Joints made at the correct angle don’t leak. Forced joints do! (I am testament to this!)

Landscaping Options & Final Word

OK, so there are a few considerations here. You can of course leave your Ultimate Stock Tank with its “raw” and natural look. Or, you can make a deck to fit around it perhaps.

You could box in the plumbing and create a wood surround.

You could landscape with some large rocks to give the appearance of a rock pool. The list of options goes on and it really is down to you how you are going to finish the top.

If you would like some additional help with the parts, detailed diagrams and a shopping list. Perhaps you would like to have some or all of the parts supplied to you. We can help. Please get in touch and discuss your requirements. If you are looking for the diagrams, they are available in the shop here.
