I have Koler whirlpool tub which was installed by my builder and when it is filled with water it pulls away from the wall about 1/8″. I feel that it needs to be supported from the bottom. Is there any type of foam that can be injected under it to help support it better. I have very little room to work in.
Fiberglass tub? When it was installed they were supposed to sit it in on top of wet mortor or cement to support the bottom because of the water weight.
