In our new addition, we had floor to ceiling tile put in the shower. After only a couple of weeks we noticed that in 2 corners of the shower there is an almost floor to ceiling crack. Builder first said it is natural settlement of house and patched part of it (with wrong color grout) and it cracked again. Now he is saying that we need to wait 6 months to do anything because as the wood dries out it will crack more. I am worried that the wood won't dry out because there will be water getting back there. Is this a flaw in the tiling/grouting job, the framing job or am I just over reacting? I am not comfortable waiting the 6 months. Should I relax or am I just being given one more "line" from the contractor?

You are getting some bull and some truth.

The corners should not be grouted, they should be caulked. Most grout manufacturers carry a companion line of caulks that match up to their grout colors. He is right that the new wood needs to dry and in doing so some shrinkage will occur. Even though it is small, you have already seen what a small amount of movement can do. Have him dig out the grout in the corners and apply the caulk instead. That could be done today, let it dry a day or two then ok to use it.

Even with the cracked grout you should not have a leak problem if the walls under the tile were constructed properly. The studs should be covered with a 4 or 6 mil thick plastic sheet or roofing felt. The corners of the backerboard in the shower should be taped with mesh tape and covered with a coat of modified thinset much in the same way that drywall tape gets coated with joint compound. Any water getting through the cement board will hit the plastic and not the studs.

Thanks for the info. Unfortunately, I have no idea what he did under the tile. It is really unfortunate that in order to know what they are doing you really need to sit there and watch every second. When they put in our radiant floor they put over 2 inches of cement over it when it called for no more than 2 coats of 3/8" thinset. He keeeps saying, don't worry, we garuntee for a year. I fear we will have a lot to repair in the upcoming years...

you are being mislead and lied to.

According to The Tile Council of America (http:// specifications handbook, all transitional areas and corners need to be filled with expansion material (colored flexible caulk matching the grout colors OR have a corner system to prevent cracking from expansion and contraction such as Schluter Kerdi (, and in fact, every grout manufacturer should have a selection matching ever grout color to make adhereing to these specs as problem free as possible.

your builder and tile company is either cutting corenrs or are inexperienced.


There are two ways to do any job. The right way and the wrong way. Do it right everytime.
