We are in the process of doing a bathroom remodel and we noticed that the bathtub we ordered does not have a flange. The bathtub will be installed in an alcove setup (surrounded by 3 walls) and will mainly be used as a shower.
The bathroom is currently stripped to the studs, the floor is not finished (just leveled).
What is best practice to install this sort of flange"less" bathtub?
We have already purchased 1/2in Durock and stone tile that will be used in the bathroom walls around the bathtub.
