We are installing an American Standard 65" whirlpool tub. It will be a "drop-in" installation into a platform built on a cement floor (ground floor).
Most manufacturers recommend placing the tub into a "mortar bed" during installation. However, I have my concerns about heat loss....our cement floor is certainly "cold".
I developed an alternate approach that would employe high-tech spray foam which forms a strong support as well as some decent insulation.
TO do the job properly, I'll probably have to use a slow-curing foam with a high strength rating.
We had planned on building a small floor out of 2x4's and can actually build a small "dam" where the tub bottom will be sitting.
Anyone see a problem with this approach ?
Anyone have a recommendation on the manufacturer of the proper foam ?
see previous explanation....
