Repairing Shower Pan

Randy32545

Installed shower pan for customer-after installing cust. wanted more of a slope in drain-can you go in and lay something like metal maze over existing concrete to pour additional or do you recommend tearing completely out the original and start all over??

Is it a mud pack shower base? How thin/thick will the additional later be at the drain and at the wall?

If you have to start with a feather edge and go up from there, I would use a vinyl modified concrete, such as Quikrete's vinyl patch. It can be feathered from 1/16" to 1 1/4" in one layer. Dampen the existing base first to help with adhesion. Then use a modified thinset and you should be all set.

What type of shower pan, how was it installed, is there a pre-slope under the liner, how was the curb built?

Yes, it is a mud pack base and I was going to add 1/4" at drain and 3/4" @ wall.

In removing tile on floor should I remove first row of tile along wall also for additional height @ wall?

R&D Tile

I understand that, what type of liner was used, lead, pvc, cpe, and is there a layer of mud under it, you don't have to remove any wall tile unless redoing the whole pan, still would like to know how this was constructed from the start.
