In response to Re: Tile shower - "pan"dora's box!
: Help someone!
: Please explain the process/materials to consider when attempting a leak free shower remodel - specifically, we intend to replace a fiberglass surround with tile (shower stall only).
: We prefer not to use a fiberglass (or other) pan for the base. Instead we'll continue with our cermamic tile. Do we need to install a rubber backing (under the cement board) and, if
: so, what's it called? Also, how high should we build the "curb" ? Thanks in advance for any and all advice!
