In response to Re: FOAM IN LIEU OF MORTAR IN WHIRLPOOL FRAME
: I am installing an American Standard Williamsburg Elite whirlpool tub and would like to know if using high density spray foam insulation would work in lieu of mortar in the frame the tub is to sit in?

Reply:
I would follow the manufacturers suggestion to use mortar, although I use Structolite gypsum mix.
The foam insulation can expand too much and knock the bathtub out of level.
Good Luck. e-plumber
