First, you'll want to know what kind of tile you should get. Definitely go for quality here. Don't put bargain bin tile in your shower. Because a shower is a small space, even spending $10 per square foot isn't going to cost you very much. Make sure it's tile you like and that you're not going to mind looking at at every day for the next several years. In addition, porcelain tile is best. Porcelain tile absorbs less moisture than ceramic
does and because this area is going to be wet every day, that's something to consider that's important.
Another thing to consider is that of course, you'll need to demolish the existing shower. What kind of
base do you have to start from? Is the shower going to be easy to get out or are you going to need some
help? For best results, rip out your existing shower and go right down to the studs. You'll want to start from scratch when you know How To Tile A Shower properly.
Still another thing you'll need is a vapor barrier. Tile isn't waterproof, despite what you might believe. If you just tile the wall and don't do anything else, you're asking for trouble. You'll need to protect the wall from moisture and the tile itself just won't do it.
Next, get some cement backer board. You're going to actually lay the tile on this. If you don't do this,
again, you're asking for future trouble. Cement backer board will give you a sturdy base to install the tile on. It's a lot like installing drywall and you simply cut it to fit and then screw it on.
Besides the tile, you'll need other proper materials. You'll need thinset and grout, and you'll need grout sealer after you've done the job. Get all the materials you need before you start. This way, you won't have any sudden stops during the process because you need to go out and get some supplies.
Lastly, bring the right tools with you to do the job right. You should have a wet saw to cut the tile
with, and you should have something to cut the cement board with, too. You'll also need spacers, buckets, trowels, and some other items to do the proper job. Unless you have the proper tools, you're not going to be able to install the shower properly. And if you don't install it properly, of course, it's going to leak down the line. That's a bad thing to have happen, of course, so avoid it by properly planning before you start the job.
