22' x 41' Kidney Polymer Wall In Ground Pool W/ Step

22' x 41' Kidney Polymer Wall In-Ground Pool Kit (42" Wall)

The 22' x 41' Kidney Polymer Wall In-Ground Pool Kit delivers a full-scale, resort-sized swimming footprint paired with a natural, free-flowing silhouette that softens backyard landscaping. Featuring sweeping curves and a gentle inward contour along one side, this spacious kidney layout blends smoothly into large landscaped yards, garden beds, and custom stone or concrete patios. Its organic shape also naturally separates shallow lounging and step-entry areas from the deeper swimming end, while its continuous curved perimeter promotes smooth water circulation with fewer dead spots.

Unlike traditional steel-wall pools that can eventually rust or oxidize when exposed to damp soil or sanitizing chemicals, this pool system is engineered from heavy-duty structural thermoplastic polymer panels. Polymer will never rust, rot, or corrode, making it completely unaffected by groundwater, acidic soil conditions, and saltwater chlorination systems. Each panel features a deep-ribbed structural backing that provides dependable load-bearing strength against soil backfill while remaining lightweight enough for straightforward handling and alignment during installation.

The 42" wall height serves as a versatile perimeter foundation that adapts to your backyard plans. Your kit comes supplied with a standard diving-approved liner design, or you can customize the liner depth and floor profile—such as a flat-bottom layout or a custom-sloped deep end—to match your exact swimming needs. Paired with continuous curved polymer wall panels, the vinyl liner seats smoothly along the kidney contour without sharp corner stress or overstretching.

Key Structural & Design Features

• Classic Kidney Silhouette: Smooth, organic curves soften hard patio lines, nestle easily into spacious or irregular yard layouts, and create natural shallow and deep-end zones.
• 42" Industry-Standard Wall Height: Pairs seamlessly with the included standard diving-approved floor profile, or accommodates custom flat-bottom and sloped excavation depths.
• Custom Liner Depth Options: Supplied standard with a diving-approved liner design, with full customization available to tailor the floor depth and slope to your preferences.
• Non-Corrosive Structural Polymer Panels: Molded thermoplastic walls resist rust, corrosion, and underground deterioration for long-term structural reliability.
• 100% Saltwater Compatible: Non-metallic wall panels, braces, and fasteners prevent galvanic corrosion when paired with saltwater chlorine generators.
• Reinforced Wall Bracing System: Includes heavy-duty polymer X-braces with integrated deck supports and ground stakes to keep walls plumb and transfer patio weight evenly.
• Non-Corrosive Fasteners: Self-aligning nylon shoulder bolts lock panels together tightly without seizing or rusting underground.
• Factory-Molded Openings: Skimmer and return openings are pre-molded directly into the structural panels for a clean, watertight seal without field cutting.

Common Questions & Answers

What are the benefits of a kidney-shaped in-ground pool?

A kidney pool offers a softer, natural look that blends seamlessly into backyard landscaping and irregular lot shapes. The gentle inward curve naturally separates the shallow lounging area from the deep swimming zone, and the lack of sharp corners improves water circulation and lets robotic pool cleaners glide smoothly along the walls.

Why choose polymer wall panels over galvanized steel walls?

Polymer panels will never rust, oxidize, or corrode when exposed to wet soil, high groundwater, or pool chemicals. They are also lighter than steel panels, making them easier to carry and position during excavation and assembly while still offering full structural strength once backfilled and locked into a concrete collar.

Can I use a saltwater chlorine generator with this pool kit?

Yes. Because the wall panels, support braces, and nylon assembly bolts are 100% non-metallic, there is no risk of saltwater causing galvanic corrosion or rusting the pool structure underground.

How deep is the pool with 42" walls?

The 42" measurement refers to the height of the perimeter wall panels, which holds roughly 36" to 38" of water along the shallow perimeter. Your kit comes standard with a diving-approved liner profile (featuring a sloped deep-end hopper), or you can order a custom liner tailored to a flat-bottom layout or a specific deep-end depth.

What additional materials do I need to purchase locally for installation?

In addition to your pool kit (and any filtration, step, or ladder upgrades you select), you will source concrete for the perimeter collar footing, pool base material (such as vermiculite or a sand/Portland cement mix), Schedule 40 PVC pipe and fittings, backfill material, and electrical wiring/bonding supplies locally.

How is the pool kit delivered, and do I need a lift-gate?

Pool kits ship via commercial freight carrier on oversized pallets. Unless you have a forklift or loading dock at the delivery address to unload the pallets from the truck bed, lift-gate service is needed at an additional cost to lower the freight to the ground. You can also save $300 by picking up your order directly at our local warehouse.

Can I install this pool kit myself as a DIY project?

Yes, many homeowners install polymer wall in-ground pool kits themselves or act as their own general contractor by hiring local subcontractors for specific stages such as excavation, concrete collar pouring, and electrical bonding.
