Hi Debbie,
You MUST put up cement board on the walls too, if you’re gonna have a tiled shower-stall!! I believe it’s required as code. Only the actual shower-stall area has to have cement board behind it, but doublecheck with some tilers/builders.
It’s also very heavy!! Have some friends handy!!
>>> Ask your tile retailer what should be tiled first. Also inquire about your subfloor requirements. Most remodels DON’T have a stiff-enough subfloor!! Usually you have to lay additional plywood.
>>> DON’T skimp here…you’re not gonna want to see cracking grout lines/tiles because your floor flexes too much!!
Thanks!
