Tiling over Tile

I have a shower that I recently re-tiled. However when I laid the shower floor I did a poor job around the drain and now I am left with a few low spots around the drain, now I am getting standing water in my shower. I am wondering about tiling over what is there now to make the correction instead of ripping the entire floor. Any thoughts?

That would be a really terrible idea. If done properly you would have to rip out the first row of wall tile, tear out the floor, use a cement bonder and re-slope. Then re-lay the tile.

It sort of depends on whether you have birdbaths in your sloped floor, or the overall slope is not correct.

Raising the drain to accommodate a second layer of tile may not be possible. I may be possble to remove the floor tile without compromising the liner...depends, it can be risky.

Many people put the floor tile in first, then cover it with the wall tile. This is not a requirement, it's just easier since the edge cuts look crappy if you don't get them straight - the wall tile going over them helps hide things. It is eminently possible to leave the wall tile in place and tile up to them. Industry standards call for that gap to be caulked rather than grouted. You could risk it and grout it, but it might fail. Doing it either way can look good...good workmanship is critical, though if you want it to look good.

I do believe the slope is fine, and the drain is able to accommodate a higher floor. I just want to make sure if I do it, I do it right.

existing tiles are one of the best surfaces to tile to so if you are confident of raising the drain and gettin the correct fall into it and keep it water tight i say go for it!

You might have to raise the floor more than you think to get a good bond between the two tiles. Unless the tile was seriously out of kilter, the drain should not be high enough to accomodate a second layer of tile.
