I agree. Get your installer in there. It shouldn't affect the watertight integrity of the pan, being that the tile and grout themselves aren't supposed to be waterproof, but it still shouldn't crack, and especially cracking this soon would make me extremely nervous about longevity of the shower on the whole.

I'm extremely disappointed in Fireclay. Why aren't they forthcoming about appropriate uses for their tile? It's not cheap, I'm willing to pay whatever...but why are they the only manufacturer that says crazing is ok in wet environments? If they had a proprietary improvement in their tile, I'm sure they would share it! I don't think they do. I had a custom tilemaker tell me that their tile is perfectly fine to go into the wet environments...followed 30 minutes later in conversation by saying there likely will be some soap scum in there and to be very careful because the grout will go into the crazing (so don't use contrasting grout). So, to me, that is NOT perfectly fine! Tile - especially at Fireclay's prices - should not have ANY of these issues - and because they will, Fireclay should be forthcoming about the technical specifications and appropriate uses. They even say their tile can go in swimming pools!!! That leads me to believe it's sealed - but then there are these issues with the grout seeping into the crazing, even after sealing upon install, so clearly it's not. Bar Keeper's Friend?! After paying a RIDICULOUS amount for their tiles and WAITING for it to be custom made...not being told the proper technical information, then being told use Bar Keeper's Friend?!!?! Wow. Gosh, Lisa, I'm so sorry. Fireclay's website has a beautiful steam shower with gloss tile with crazing ON THE FLOOR of the shower. Every tile manufacturer and salesperson says not to do that - and common sense agrees - it's gloss and you'll fall on your booty! I tried to research applications on Fireclay's website because I wanted to be assured that the tile is ok. Their new Essentials line - the blog posts are clearly computer generated (same exact bathroom with different color tiles). The tile I wanted in a hotel - couldn't call the hotel because they have no phone number. Shady. Oh, and I Googled "Fireclay complaints" to see if anyone was unhappy with their crazing or the durability of the tile. No consumer complaints, but I did see a settlement with the State of California for violation of environmental regulations (i.e. polluting). That was the cherry on top for me, as SO MUCH of their literature is how good they are for the environment. Fireclay makes a truly beautiful tile. I'm very disappointed that I will not be moving forward with them. I wish they were just honest about proper applications - I'm shocked they wouldn't be. Wouldn't you want happy customers?!?!?! If there wasn't a series of red flags, I would have bought it for the whole house!

I know what you are saying but please post photos.

It's probably gonna fill with contamination and look nasty, but if your waterproofing is done correctly it's not going to leak. Try filling it with thin super glue before it gets bad. Did you get a plastic valve cover? That's how large the hole should be. I'll bet your tile is covering your escutcheon screw holes. If you've gotta recut the hole, you may as well replace the tile.
