Shower floor replacement
Hello all- I'm a new member and I'm not sure if this is the right forum. I didn't see one for tile, so I'll throw it out there and see if someone can help me out. To make a loooong story short, we recently had a house built and the guy screwed up our shower floor and it needs to be replaced. I've laid tile in my old house and feel confident in that aspect, but I've never done it in a shower. I know there is a shell underneath and that is my concern. Does it go up into the lower tiles of the wall? Am I going to have to replace the shell as well as the tile? The problem originated with bad grout. Is there one grout that is better than others for this kind of job? I would really appreciate any advice you can offer. Thanks in advance and I'll be checking back in about an hour (9 am) if you need more information.

Does it leak, what do mean it has bad grout?, need more info on what the problem is, why redo it all if the grout is bad.:)

What type of grout is it?

Yes, the pan usually goes 4 to 6 inches up the walls, so it is under the first row of wall tiles.

What do you mean "bad grout"? And what happened that you think the tiles have to come up for replacement. How about cleaning out the "bad grout" and regrouting the floor?

I don't personally find any differences in brands of grout, but many professional tile men have their favorite brands. Stick with any brand from a flooring supply house and I think you will be ok.

Someone is bound to try to convince you to use epoxy here. Stay away from it , as it is very unforgiving.

The grout is flaking out and tiles are coming up around the drain. I had a guy come out and try to fix it twice. He worked for the builder and he said after the second time that if that didn't fix it, it would need to be replaced. In hindsight, I don't put a lot of faith in what he said, so maybe I can get by with regrouting. I think he just grouted over the old grout without removing it. What is the best way of removing it? I have a Dremel, but have hardly used it. What about the tiles that are popping up? I appreciate the advice.

I have no idea what kind of grout it is. It started to dry out and flake almost immediately.

Pictures might help get you a better understanding, and a better answer to your problem.

Can you provide some information on the construction of the shower? If grout is coming out and tiles are loose you have some serious problems that regrouting is not going to help. Do you know what kind of thinset and grout were used? Just wondering if this wasnt some of that premixed stuff.

I don't know what they used on the floor and I can't get that info since the builder is no longer returning my calls. I filed a complaint with the building dept, but they can't do anything if it's not "structural damage". I'm done dealing with him and just want to take care of it. We haven't been using it (the shower), but when I get off shift tomorrow I'll check and see if they are still loose. One of my main concerns was that the thinset didn't seem to be drying. It was, for lack of a better word, gooey for a long time after it was installed and that's where a couple of the tiles came up. I believe it has since hardened. Thanks again.

HJ1 10-31-2006 04:01 PM

Sounds like another case of premixed thinset. If thats the case you'll need to remove the tile, remove all the goo and reset the tile with real thinset. The kind that comes in powder form in a bag that you mix with water or admix. Sorry for the bad news. If the builder used this crap he should be responsible for paying to fix it.

Or mastic, still no good, he probably used whatever it is on the walls as well, I would also be worried about what else this guy did to cut corners.:furious:

wgfirefighter 10-31-2006 08:11 PM

I appreciate all of the advice. I'm gonna go home tomorrow and take a good look at it. If whatever they used has hardened will I still need to replace it all? I'm hoping (after reading these replies) that I can sand down and replace the few tiles with good thinset/mastic and regrout it all properly.

Now , with tiles popping loose, the problem sounds more serious. Makes me tend to agree with you on wanting to remove the floor and do it right. I also suspect mastic was used instead of thinset. Is there a mud bed in the pan or did someone just stick the tiles to the pan directly? Unfortunately this sounds like a redo inorder to get it right. A half way fix on something like this will haunt you forever.
