Hi Ed,

Yes, yes and yes. :) It's legal and you must have a shower pan liner. Hop on down to our place and sign in. The folks will help you with the project. :)

: Hi. I'm looking to expand our old 30 inch neo-angle shower that is located in our basement. I won't be moving the drain,, but I do want to build out the shower sevveral inches and still use an off the shelf neo angle panels and door.

: The issue is, since I am on a concrete slab, and plan
: to custom frame the unit with wood, cover with backer board, seal, and then tile, do I still need to install either a PVC, or copper or lead liner? I could have a custom plastic or vynyl liner made, but that would be cost prohibitive, and we prefer the look of the tile.

: Which brings another point. Tile on a shower floor. Assuming it's legal to have tile at all, should/can you even use a liner with a tile floor?
