Uh oh! We just put in a marble hex floor on our small shower in the powder room. But we used crema marfil, though I'm sure it has the same problems. The door was just installed and we still need to have the room painted and so haven't used the shower yet. It would only get limited use because hubby showers in there on very early golf days once or twice a week so he doesn't wake me up. Very considerate : ) Hopefully with limited use this doesn't happen but I have no idea and am now a bit worried. Charlesg270, any update? Have you used your shower yet?

I saw your posts on Tile Geeks, GTP, etc. I’m glad that you are undertaking this experiment. It’s valuable information for homeowners and Pro’s alike. Please post the photos directly here, in your post, rather than linking to a blog. Houzz tends to view posts designed to generate traffic for another website as spammy.

We stay in a very old hotel in Rome that has cararra marble everywhere in the bathroom and it has been there since 1947 there is no discoloration anywhere, not in the shower or the walls so maybe check with Italy they have been using this stone for a very long time.

I’m sorry this has happened to you. As a homeowner who dealt with something like this 2 years ago, here’s my advice: By email, ask the contractor to come meet with you to address your concerns about the shower. Before the meeting, order an online download of the TCNA tile manual (about $40). Read the shower construction sections. Also before the meeting read the online manufacturers instructions for the materials they used, if you know what they were. At the meeting, have a friend or spouse there to take notes. Use a checklist, go through your concerns, and ask the contractor to inspect the shower and diagnose the problems. Ask them to propose a plan for fixing the problems. After the meeting, type up the notes so you don’t forget what was said in the meeting. Send an email to the contractor re-capping the meeting and confirming the plan for the fix. Let them try to fix it. Make your home and schedule available, don’t interfere with the work. If/when the fix fails, send an email to the contractor expressing how disappointed you are that they were unable to fix it. Ask for a refund. After they refuse the refund or they ignore you, send a demand letter. After they ignore that, you have to decide whether to sue in small claims or district court. Meanwhile, you’re going to have to hire and pay a new pro to re-demo and re-build your shower. For that, since you have read the TCNA tile manual, you will know what the new contract should have in it. And you can post your new proposals on here to ask pros if they are correct. The whole court thing thing is a real PITA. In our case, the bad pro quit leaving us with an unusable and trashed bathroom, refusing to return to fix anything, refused our refund request, then sued us for payment for “mystery” cabinets that they never built or delivered. We responded in district court, represented ourselves, and won the case, made whole by the judge. The key was having everything in email as documentation, giving the contractor a chance to re-do it. Also we provided a cost analysis to the judge to show the dollar amount of the damages to us. With these hacks, it’s a numbers game. They can do hack jobs for years and years, sometimes never having to pay for their lies and cheating. Most of the time they get away with it. P.S. Our hack was the high bid and put all the right words in the proposal, they just didn’t do any of it. So you do need to read that TCNA manual so you know what to look out for next time.
