    Default shower floor

    I will be turning my bath/shower into a shower only and have had two different recommendations for the soon to be tiled shower floor. Mud/Rubber/cement or mud/fiberglass. I was told fiberglass moves and the tiles may become disloged but I was also told it was better for preventing leaks. Don't know which way to go.

    Check out johnbridge.com

    Fiberglass 'receptors' are not (generally) intended to be tiled upon. They're mostly prefinished.

    There are 2 ways to do a tiled floor:
    1) mud bed + membrane

    2) preformed shower base. Check out Kerdi from Schluter Systems. It's a 'foam' tray that gets cemented to the floor, protected with a membrane, and then tiled upon. It works in conjunction with a special drain also sold by Schluter.

    You can find out all about it at jb or Schluter's website.

    Shower floors needs to be properly sloped. You may be able to find a preformed base if your floor is one of the standard sizes. Custom or wonky shaped floors usually fare better with a mud floor.

    I'm all for the prefab shower bases or "receptors" as they are sometimes called. There is quite a variety in the sizes.

    A properly membraned floor will be as strong and leakproof as a fiberglass receptor.

    You still have wp the walls. A receptor can still leak at the wall/receptor junction. With a fully membraned shower, there is no 'seam' there. But you gotta membrane up the floor.

    At this level of leak-proof-ness, I am discriminating based on ease of installation.
