I have one of those almost 20 year old whirlpool tubs that only sprays out black schitt when you turn it on, and I never use it anyway. I want to rip it out and and do a walk-in tile shower. The house is on a concrete slab. What is the do and don't's to this operation? What are the key things to do for a floor and wall? Is there a special tile, grout, sub-floor material? TIA.
I still build them the old school way. The most important thing to make sure of is that there is a pre slop installed on the subfloor prior to the pvc membrane being installed. Once the membrane is in make sure the shower drain collar is sealed underneath and on top prior to the mud bed being built. The walls need at least 2 layers of red guard water proofing painted on .some guys will seal the surface of the mud bed but I don't like to.Make sure all the corners are sealed very good prior to the tile being installed. Get porcine tile. You will need a mosaic tile for the shower floor to cove with the concave mud bed.
