Durrock or other for shower?

I'm a DIYer and I've only done one shower stall. The poster that mentions the slope, I feel, is correct. I had a "L" shape walkin shower floor to do and I wound up using the "Dry Pack" mud (I died of sticker shock from the preslope foam packages) and a custom built slope. Then the rubber liner, tested by filling with water and letting it set, then another layer of "Dry Pack" mud then the tile. Kind of a pain to get the slopes right before the mud sets up. You need a good finish on the slopes to get the tile to set properly (I used the 2" squares). If you desire you can slope down from finish floor level (drain has to be set at a lower level) so you wouldn't need a raised sill to step over, just something to consider. bjr23

The entire shower needs to be water proof. Tile with grout is not water proof, neither is Durock. So regardless of what you use, it has to be made water proof before you tile.

I used the Shlater system including the foam base. It included the drain which also handles any water that gets under the tile. For the walls, I put in 2x6 blocking in places for any future Han holds and documented where I put them. I built a corner seat. Used drywall for the walls.

Then applied shluter fabric (like wallpaper but water proof). I don't remember what product is used to adhere it. Works great. I'm a believer. Then I tiled the floor with 2 in squares. I added something to the grout when mixing it that seals it. My bill also used the shluter stuff on 2 showers several years ago. No problems.

My sil hired a friend who is a professional tiler. He created his own pan including the rubber and then more dry bed on top as mentioned above. He used Durock on the walls and coated the walls with a waterproof product, made specifically for tiling.

Either method will work. Just don't rely on tiling as your water barrier.
