Hello. I have learned so much from reading the threads on this site but I have run into a slight problem with a tub install. I have searched and found several topics with the same issue.
I have a Bootz porcelain over steel tub from HD. The tub has a stryofoam base. When the tub rest on it's base it is stable but is no where near level. Bathroom floor is solid concrete and level. When leveled with a stringer the stryofoam base on the srtinger side is about a 1/2" off the ground but does touch on the apron side. This creates lots of flex and squeaks.
Should I just scrape off the stryofoam and motar bed it? When I shimmed it it seems like the stryofoam just compressed around the shims.
