I recently had a contractor install a mosaic tile floor in a shower. Unfortunately the floor was not pitched correctly and is level. So water puddles instead of flowing towards the drain. The shower pan was done correctly prior to this with a preslope and panliner installed below the final mud bed.

Is there any way possible for me to create pitch by adding more thinset on top of the ruined floor without removing the tile, pitching it towards the drain and tiling over that? The drain should still be adjustable up to accommodate if needed. The tile itself is the 3/4" x 3/4" mosaic tumbled marble finish. Would this be an acceptable approach?

I appreciate the help!

Thanks again.

It would be risky to patch and re-slope the floor leaving the tiles in place. It might work? I say that because it'll take you several pores to get it right. Plus I'm not so sure the drain will unscrew. It's best to remove the tiles and work off the deck mud instead. You'll have to raise it probably 1/2" around the perimeter depending on its size.

Is the person that did the final slope out of the picture now?

Well fortunately or unfortunately he's out of the picture. This is the second time he screwed it up. At this point I'm on my own. So if I can get the tiles off cleanly how would you raise the level of the mudbed? Is skimcoated thinset OK or should I use more mud?

Thanks for the quick reply.

Deck mud isn't going to work at all. Thinset will not either. I would use a Portland based patching and leveling cement. Do NOT use a SLC, self leveling cement. You may be able to correct the slope in a few tries? Remember, 1/4" per ft to the furthest corner in min. slope.

Jaz, can you recommend by name exactly what to use please? Also I'm assuming I'm troweling that on and creating pitch, let dry and then thinset/tile over that? Is this what you mean?

Thanks.

I am confused, how did you go from a correct sloped pan to flat? I would not try to put more band aides on this and just tear everything he did out down to the sloped liner.
