6 Bad Remodeling Ideas for Tile Shower Construction
Sheetrock in a shower and other bad ideas
Sometimes it’s nice to know what-not-to-do when remodeling a tile shower in your bathroom. Here’s a list of just a few of those things:

1. Drywall Shower Walls
Drywall (sheetrock) falls apart when it gets wet. Putting a product like this in a shower is just a bad idea.
I should mention that there are a couple of companies that will warranty their waterproofing over drywall. For example, Schluter approves their Kerdi Shower System over drywall in showers. The theory being that moisture should never penetrate the waterproofing on the surface.
So if you insist on tile over drywall in a shower then that’s how you “waterproof drywall” for showers.
Please keep in mind that liquid waterproofing products are not approved for this purpose. So if you see your contractor applying Redgard or another “waterproof paint” over drywall you might want to put a stop to things sooner rather than later.
2. Not taping and mudding the seams
Cement board is 3’x5′. I’ve walked into people’s homes that had cracks in their tile 3′ high all the way around their shower. This is a result of the walls flexing and the installer not taping and mudding the seams.
Make sure the seams in your shower enclosure are covered with alkaline resistant mesh tape.*
3. No waterproofing
I’ve covered this elsewhere but a shower should be waterproofed. So if you see a contractor tiling directly to cement board or Hardibacker then check and see if there’s plastic or tar paper behind the wall.
If not, read these posts and have a talk with him or her.
4. Not replacing your old faucet
One of the problems with remodeling is that once you get started it’s hard to draw a line of where to stop.
Take a good look at where the faucet is in relation to your home. What’s on the other side of the faucet wall? If it’s simply a closet or interior space then it could always be replaced from that side. Usually, this would include patching the drywall but otherwise isn’t too invasive.
If the other side of the wall is, for example, kitchen cabinets or the exterior of the home then you’re going to want to very seriously consider replacing the shower faucet while you have things opened up.
5. Tile mastic adhesive in a shower
Tile mastic is a premixed organic adhesive used for sticking tile to a wall. It comes in a bucket and resembles glue more than a cement mortar.
There are very few situations where mastic is an OK choice. Don’t use tile mastic in wet areas like showers, over cement board, fiber cement board, Kerdi, floors, or with glass tile, large format porcelain tile, natural stone, or most anywhere else.
The only place it’s OK to use it is when tiling in non-wet areas, over drywall, with small ceramic tile. These days that’s almost nowhere.
6. Not doing a flood test
If your shower is going to leak, wouldn’t you rather know sooner, before it’s tiled, rather than later? Wouldn’t you like to know that your shower doesn’t leak before you make your final payment to your tile contractor?
A simple flood test will help to determine this. Consequently, I would write it into your contract with your tile contractor
Just like baking a cake, it’s the ingredients that matter. If you are paying for a new tile shower and see the things listed above, I advise you to start asking questions. However, if you went with the low bid, you might not like the answers.
