Where can I place my Freeflow Spa?
Effectively a firm and level surface
While a concrete slab is best for long-term use, other foundations like pavers, gravel, brick or wood decking are acceptable.
Always put your hot tub on a structurally sound, level within ½" per 10’ surface. Make certain that the location you choose can support the weight of your filled hot tub. A reinforced concrete pad at least four inches thick is suggested.
For a deck installation, you must know the deck’s maximum load capacity. Consult a qualified building contractor or structural engineer before you place the hot tub on an elevated deck or indoors.
