So I am starting on our main bathroom remodel and we want to do a walk in shower instead of a tub (there is a tub in the downstairs bath). I understand how to do the sloping for the floor drain and shower liner. The question i cant seem to find the answer to is do i need to do any prep to the subfloor like waterproofing or changing the type of wood before laying the mortar and shower pan? via /r/DIY https://ift.tt/2QuvvAV
