First be okay with the fact the bathroom tiles might need to be replaced. All of them. Replacing them in the bathroom will have the least impact on the rest of the house and whatever comes out in one piece, can be stored for future cracks. Maybe you can find a similar color but a different size, so it won't look too awkward, just an idea. Taking out a cracked tile is quite easy. Put on some gloves and safety glasses and (carefully) smash the broken tile with a hammer. An old screwdriver or chisel will help you tilt the pieces out. Work from the hole outwards to remove the other tiles. Removing a good tile is nearly impossible. Assuming it is still glued firmly, I'd say impossible. But, if you want to try anyway, you'll need to mill out the grout and then figure out a way to lift the tile..

Geez chookchook2 you are interesting. Again, negative sarcastic humor. Another innocent targeted with a reply that has nothing related to applecakes1 legitimate question. FYI Arafat's keffiyeh wasn't chevron. and BTW, I've followed Houzz for a longtime. Your vile comment to another innocent on the dilemma of the vaulted ceiling space is what made me open sign up. To applecake1; pay no mind those yuks ... a saying from my late mum.

Thank you. My husband and I chose the tile (per recommendation at the tile store) and used a professional tiler (per recommendation at the tile store) for the install. It isn't a flip. This is a family home that we purchased and spent a year renovating—not DIY but with all professional hired help and a contractor to oversee the job. This tile person wasn't hired by him, though, as he was happy to use the person that we were told was very good by the tile store…. My heart is sinking. I absolutely hate the idea of retiling the shower as there is matching tile on all walls, including shower. I'm hoping there is some other idea out there that will help. I do personally think the tiler should have informed us if the tiles we supplied to him weren't suited to be mitered…we discussed it even before tiles were purchased and he didn't mention any specifications. I'm just worried now that if we put it on him to fix it, we'll end up with a bigger mess...

Stacked splashbacks always look wonderful!
