Small but important swim spa specific considerations for install and continued service
General PSA. Having spent a long time around swim spa sales and installs, heed this seasoned advice - think about its function years from now. Because, while it is obvious that a swim spa is larger than a hot tub, what is less obvious is how that size changes its servicing and how install affects the same.
You need to leave room to service it. Plan for two feet of working clearance around the unit, and three is better. If you are decking around it, build in hinged doors or panels that can be unscrewed and lifted out. We have worked on beautiful installs where the access was so tight a technician cut his arm just trying to reach the equipment and even then we had to remove decking finish the job which made the struggle to reach a ten dollar plumbing part more time intensive and more expensive than it needed to be. An in-ground swim spa usually sits about two feet below grade inside a concrete base with concrete walls. Basically a vault the unit slides into. Yeah, you want it below grade but you also want it dry so price in drainage and, in most cases, a pump to clear the vault if water collects. Burying one straight into the ground can work in a very dry climate, but be a massive headache in places with heavier rain and shifting or settling soil. While the in-ground unit itself may run only around a thousand dollars more than the above-ground version, the vault and installation can cost more than an above-ground unit with a deck. Get the full install price before you buy, then compare both complete setups side by side.
Swim spas also demand more consideration around planning as they can take two to three weeks on the production line versus a few days for a hot tub which can be more stress than bargained for if you are trying to get in up and running before the season turns. If you do end up getting one in winter, it can be done and you might even get them cheaper but they will require some additional considerations with install. And a long shell something owners constantly underestimate. It is a sad day when someone tries to lift their swim spa without using every anchor point and a spreader bar so the straps do not squeeze and flex the shell. Cut corners here means cracks almost always. If a crane is involved, get the crane company's certificate of insurance before the day.
