A swim spa is the perfect centerpiece, offering the best of a pool and hydromassage, exercise and recovery—all year round. Here are your foundation options to consider:
Concrete: The quickest and easiest way to install a swim spa is above-ground with a level, structurally-sound and level. The concrete pad should be slightly larger than the swim spa, and large enough to accommodate steps if needed. The slab can be expanded even further for space to walk around.
In-Ground or Below Grade: Having your swim spa partially or fully submerged in the ground is an attractive option. The swim spa is placed on a concrete pad, partially or fully recessed in the ground. This needs a level concrete base and concrete retaining wall to form a “bunker” for your swim spa.
Frame Shim for All Installations: It is mandatory to have full support of all gussets on your swim spa to keep it level and prevent bowing, so you may need to add a frame shim. You may not need a shim if your slab is perfectly flat and the frame makes perfect contact with the ground. Every swim spa will be delivered with a packet of shims in case they are needed.
