That would be far too 5 minute fad that is over with busy, even if it were a tile.

We had a really bad experience with Merola's hex tiles, so I wouldn't recommend them. The batch we had were really poor quality and all improperly set on the mesh--our tiler finally refused to continue with them when they kept shattering when cut and he was constantly having to pull them off to reset them. We replaced them with a similar tile from a local tile shop that ended up costing about the same for the project since they sold it by the square foot, while Merola is sold by the case. So while I like that pattern, I'd look around for other makers of it, even if the initial cost per square foot might look higher. Especially if you plan to tile it yourself, you will get that cost back in not having to reset everything a million times. For the medicine cabinet, I'd look for something similar just without the side lights, and recessed. There are a bunch out there with the same general mid-century aesthetic--then you can wire sconces on the side instead of the attached lights and have better overall lighting while keeping the general look/feel of the era.

Patricia et al. He used Durock for the shower walls. I have no pics but I saw it. Most Durock is not waterproof. How did he waterproof the shower? That is the concern. If he didn't do anything else. How did he tape the seams? What type screws did he use? How did he water proof the floor and tie it into the walls? Why we're concerned is because if he didn't even know or understand that wood in a shower is a big no-no, how would he know to waterproof correctly? You may have a major mold problem in a short time if there was no proper waterproofing. Tile and grout are NOT waterproof. In a properly waterproofed shower, you could use the shower without ever adding a tile. The decorative border tile was made by me. They are tile blanks, glazed and fired, with ceramic waterslide decals sourced from Stoke-on-Trent England, and fired again. Im a successful ceramic artist and I dare anyone to criticize those! 😂 I think the tile is beautiful and don't listen to Patricia. She only likes large format bland tile for a shower. She insists EVERYONE should do it her way and she also insists everyone needs to use 4000k lighting.

Have you gone to see his work at other places and talked to other home owners? That should be done before you ever contract with someone. It just might keep you from joining many of the others, we see on this forum, with shoddy workmanship.
