Would this be any different than a source/vendor for quartz countertops? If not, I used TrueStone in SF and thought they were excellent.

Thanks. I'll check them out, but I believe quartz wall panels are usually thinner than countertops.

We are using quartz for a tub surround and behind the toilet up to the vanity. I found that Cambria, Caesarstone and Silestone all provide some thin ones. There are likely other quartz companies that do it as well. It is around 1/2 inch or 13mm. We ordered Dreamy Marfil from Caesarstone. It's not in yet due to countless delays with our bathroom reno. But hopefully will be before the end of this month. Caesarstone only made about 10 of their patterns in the thin slabs. I think all of the Cambria ones could be ordered like that. I didn't check as far into Silestone, but I think maybe all of them are available in the thin version. I did get the impression some fabricators didn't feel comfortable working with the thin slabs so that may also have some bearing on what you do.

Looking for another recommendation other in addition to TrueStone. They have not returned my email, which doesn't say much for them wanting my business.

Thanks.
