I know Ive seen a thread on this subject but I cant find it. My plumbers are getting close to roughing in the jetted tub. My question is what type of bedding do you use to set these units. Sand, mortar, expandable foam, equipment pad grout??????

I've heard guys are using spray foam, havn't done that and don't actually know anyone who has.

Anyone doing this?

I think its better than nothing, however, you have to be careful what type of foam you are using - if it expands too much, its gonna lift or warp the tub.

Concrete is also, well, concrete - foam is obviously not that hard
