INSTALLATION PROCESS
Here’s what the build actually looks like – from ground prep to final setup.
Choose your spot
Choose an area with access to power and water and enough space to work. The right location makes setup effortless.
Prepare your site
Mark the pool outline, clear the area, and be ready to dig and excavate as needed. Your base must be laser leveled and compacted before moving forward.
Wall system support
Ensure the wall system is supported by a sturdy, durable base. Our installation guidance covers our recommended support method, but you’re free to use your own approach as long as the wall system is properly supported.
Wall system assembly
Assemble the pre-drilled steel wall panels using the hardware provided. This step forms the primary structure of the pool.
Flooring and insulation
Install your selected flooring option and wall insulation foam. Install corner edging. This step prepares the interior surfaces the liner will sit against.
Liner installation
Install the liner and ensure it is properly aligned before filling. Careful setup at this stage makes the filling process easier to manage.
Set the liner, fittings, and trim
Begin filling the pool with water. As the water rises, smooth and adjust the liner to remove wrinkles and ensure proper positioning. Once the liner has settled, install the skimmer, return fittings, and finish by securing the top trim.
Equipment and plumbing
Assemble your pool pump and filter according to the manufacturer’s instructions, then connect the plumbing between the equipment and the pool. This step completes the circulation setup.
Pool entry
Plan and install a safe way to enter and exit the pool. Depending on your setup, this may include a ladder, steps, or a custom deck or platform.
What’s included
Everything you need to create your backyard pool – right out of the box.
Galvanized Steel Wall System

FREQUENTLY ASKED QUESTIONS
We ship DIY kits by freight to a carrier pickup location (terminal pickup only). These pickup terminals are typically located near major cities, and you can view available locations on our map by selecting your state. Once your kit is purchased, we’ll email a confirmation and coordinate delivery details with you.
At this time, we do not offer home delivery. All deliveries are sent to a carrier pickup terminal for customer pickup.
Your kit arrives as one bundled freight shipment, packaged for carrier transport. The exact packaging can vary slightly depending on your pool size and selected options.
Dimensions and weight vary by pool size and selected options, but a typical shipment is approximately 113 in (L) x 46 in (W) x 33 in (H) and around 450 lbs. Larger pool sizes and add-ons can change the final weight.
You’ll need a trailer, and we recommend a minimum 6’ x 12’. A truck bed is not recommended for safe, secure transport. Most terminals can load the bundle with a forklift, but it’s the customer’s responsibility to contact the pickup terminal in advance to confirm their trailer is suitable for loading and to secure the shipment for transport.
Once your shipment arrives at the pickup terminal, you typically have 3 days to pick it up before storage fees may apply.
To contact us, please email diy@stainlessswim.com. If it’s a troubleshooting issue, include photos or a short video so we can understand your setup and help more accurately.
Please email diy@stainlessswim.com with a brief description of the issue and include photos/videos of your setup so we can better assist.
We aim to respond within 24 hours during business days. Response time may vary slightly during peak season.
We provide a short installation overview on our website. After purchase, you’ll receive the full detailed installation manual with pictures and step-by-step instructions.
If a part is damaged during installation or you believe something is missing, email diy@stainlessswim.com and we can help with the replacement part you need.
The most common issue is underestimating the build. A successful install takes careful leveling, base prep, and basic construction skills. Take your time, follow the guide closely, and email diy@stainlessswim.com early with photos/videos if you get stuck.
This is a real DIY build, so general construction experience is recommended. You should be comfortable using basic tools, doing site prep, and handling basic plumbing connections. The main work is preparing a solid, level base, assembling the wall system, installing the liner, and connecting your equipment.
Our pools are bottomless by design, so the base you build supports the liner and the water. You’ll need solid, level, well-compacted ground—most customers use a leveled, compacted sand base. Make sure the surface is smooth and free of rocks, roots, and anything sharp that could damage the liner.
Yes. Any general contractor can typically complete this project start to finish. You do not need a specialized pool builder.
Most customers complete the build within a couple of weekends.
We recommend at least 2–3 people for assembly and liner setup.
Like most DIY projects, you should expect some minor modifications or adjustments during installation.
Yes. Sloped yards can work, but the pool base must be level, which typically requires excavation and leveling.
No. A concrete slab is not required, and many customers use other alternative foundation methods.
The pool can be installed semi-inground or fully inground when proper drainage and backfill methods are used. We recommend applying our optional Liquid Rubber coating on the underground portion, and leaving at least 4 inches of the pool wall above ground for future maintenance access.
If you choose our equipment package, it requires 120V power and a GFCI-protected outlet located within about 5 feet of the equipment. If you supply your own equipment, follow that equipment’s requirements.
We recommend locating the pool equipment within 20 feet of the pool.
Our pools are made from heavy-duty 20-gauge galvanized steel with a corrugated design for added strength and durability.
Compared to stock tank pools, StainlessSwim pools are typically larger, deeper, use a vinyl liner, and can be installed above-ground or in-ground. Compared to typical above-ground pools, our wall system is much more heavy-duty and designed for a cleaner, more custom look.
Our DIY kits are offered in round pools only. Round pools are the easiest to build and maintain, which makes them a great fit for DIY installs.
Our standard depth is 4 feet, and we also offer custom depth options. We can do shallower options at 2 ft and 3 ft, and various depths between 4–5 ft for the best fit in your backyard.
Yes. Our pools can be installed above-ground, semi-inground, or fully inground as long as proper base prep, drainage, and backfill methods are used. For below-grade installs, we recommend our optional Liquid Rubber coating on the underground portion.
The pool is bottomless by design. The liner holds the water, and the base you build supports the liner and the water.
No. The top edge is finished with our top lock rubber trim, which secures the liner in place and creates a clean, safe-to-touch edge.
We don’t recommend dogs in the pool. Dog claws can damage the vinyl liner.
For above-ground installs, we recommend an A-frame ladder (sold separately). For semi-inground or inground installs, most customers build an exterior deck platform. For interior entry, we offer a stainless steel ladder, but you’re welcome to use any ladder or steps you prefer as long as they are vinyl-liner compatible.
In most cases, no. StainlessSwim pools are larger and deeper than typical stock tanks, so the water temperature is more stable. Since the pool is bottomless, it can also cool naturally through the ground, and the water helps keep the metal from getting hot. Like any pool, temperature still depends on sun exposure and placement.
With proper installation and maintenance, these pools can last for decades. The biggest enemy is leaks, because constant moisture in one area can accelerate corrosion. Water chemistry, drainage, and environment also matter.
We use a swirl bottom pattern liner, which helps hide debris and minor bottom imperfections. Our liner is a heavy-duty 25-gauge vinyl pool liner.
We use an overlap liner that folds over the top edge of the pool. It’s secured with the included top lock rubber trim, and once the pool is filled, water pressure helps hold it in place.
With proper care, liners typically last 10–15 years. Proper care means maintaining balanced water chemistry and avoiding rough use. If the liner is punctured, it can often be patched, even underwater.
The most common mistake is overestimating the size they need. Many customers initially think they need the biggest and deepest option, but the pool often feels much bigger once it’s installed than it seems by the numbers.
The wall system components supplied by StainlessSwim (galvanized steel walls and matching wall hardware) are covered by a 10-year warranty against defects in materials and workmanship. The pool liner and any equipment or third-party components (if purchased through StainlessSwim) are covered under their manufacturer warranties.
Yes. Semi-inground and inground installs are allowed, but proper drainage and backfill are required. For below-grade installs, we recommend Liquid Rubber coating on the underground portion to reduce corrosion risk.
Common non-covered items include installation or site-prep issues (base/leveling, ground shifting, drainage/backfill), liner punctures/tears/cuts, mechanical damage, misuse or accidents, improper maintenance or winterizing, and damage caused by water chemistry issues.
The liner is covered under the liner manufacturer’s warranty for 15 years. Liner warranty coverage applies to seam separation and does not cover tears, punctures, cuts, abrasion, chemical imbalance, or other installation/handling damage.
Rust or corrosion caused by water chemistry, environment, salt exposure, scratches, leaks, or installation conditions is not covered under warranty.
Saltwater systems can accelerate corrosion, so we do not recommend them. Any salt-related corrosion or damage is not covered under warranty.
