Thanks for the insight. I found this contractor on a local group. They said they were a master tile setter
They are not.
I did take pics after the waterproofing was done and here is a final pic with the grout. What really has me worried now though is the lippage on this tile by the faucet
The tile lippage is the least of your concerns. The faucet escutcheon can be sealed with some silicone sealant all the way around, and that will fill that gap.
The problems are:
- he did not tape the seams on the cement board. You can read this on page 2 of the installation manual.
- he did not complete the waterproofing - he only applied it to the seams. Cement board by itself is not waterproof. It will get wet. This won't damage it, but cement board is attached to studs, and so the studs will get wet and eventually rot.
- he put no finishing on the tile edges (grout is not tile edge finishing). This is aesthetic, but this is not what tile edges are supposed to look like.
- most importantly, he did not waterproof the seam between the walls and the shower pan, and the edge between the bench and the wall, and the curb. These are the three most common major leakage areas, and you will likely have problems. I've taken apart dozens of showers that have water damage in these three areas.
Of course if you bring these things up to them, they will claim that cement board is waterproof, and that that seams don't need to be taped, because "they've never had a problem". They are wrong.
I hope you haven't paid them yet.
