walk-in shower.

These walls are going to go and we'll replace them with this beautiful new tile.

In this video we'll show you how to do the prep. For the installation, check out How

to Install Shower Wall Tile on Lowes.com/HowTo.

You've got many choices with wall tile. Whatever you like, Lowe's has all the styles.

Just be sure to follow the instructions that come with your tile.

For our project you can find the steps, tools, and materials on our website—along with

some helpful tips.

One thing... since we're installing in a shower, we're going to have a few extra steps than

you would if you were tiling, say, a backsplash or another wall area.

Before you get started, figure out how much tile you'll need. Measure each wall area,

length times height, add 'em up and add 10% for extra.

All right, here comes the fun part—demo. We have to get rid of all this old tile. You're

in luck if you're starting with bare walls. Remember, don't start tearing into anything

until you've turned off all the power to the room—and adjacent rooms—just in case.

And if you're doing a wall that has outlets or light fixtures, remove those.

If you have old tile over concrete backerboard, sometimes you can remove just the tile with

a hammer and chisel. But typically it's best to remove everything to the studs and start

fresh.

This can get messy, so remember to protect your tub and floors.

OK, so we're down to the studs. At this point, if you need to reroute any plumbing or electrical,

now's the time to do it.

Now this is important.

If you see any black mold in the walls—stop and call a pro to remove it.

Now, we installed the new shower base and removed the old tub using the instructions

the manufacturer gave us.

Since the shower is a wet area, we're going to install a moisture barrier over the studs.

Plastic like this will work just fine.

Hold the plastic just over the shower base, making sure it hangs inside the base, and

staple it to the studs all the way around the surround.

Now, cut the bottom of the plastic so it still overlaps the flange and just touches the base.

Next step—putting up cement backerboard.

This is going to provide a strong foundation for our tile.

We're installing our backerboard

about six feet high, and it will be flush with the drywall at the edges or just outside

the shower area.

At the bottom it will be about a 1/4- to 1/2-inch above the shower base.

For an average DIYer, hanging this stuff is a two-person job. Hold it in place against

the studs—shims below keep it at the right height—and secure it with cement board screws.

Put in a screw about every eight inches.

If you need to cut the pieces to fit—score it and snap it. To cut curves for the plumbing,

use a jigsaw with a carbide blade. Cut this stuff outside.

Install all of the cement board, keeping the pieces tight together.

After the cement board is secured you need to tape the joints. Apply the cement board

tape, then another coat of mortar, and let it dry overnight.

After the mortar has cured, it's smart to apply a waterproof coating that acts like

a membrane to the cement board. Brush it on the seams and joints, let it dry, then apply

two more coats with a roller. Each coat takes about 30 to 60 minutes to dry.

From this point on the installation is the same as putting tile on drywall, like you

would for a regular wall or backsplash.

On to the layout.

Check your horizontal layout by marking a line in the center of the work area. Set the

tiles along the wall and check the ends. If the tiles are too thin, adjust the layout

to get wider pieces at the sides.

Next, check the vertical layout. This is where it can get tricky.

Plan on full tiles at the top and cut tiles at the bottom. Since we'll cut the tile to

fit, it's best to start one row up from the bottom because the shower base might not be

level.

To determine where to mark the starting line, use a level to find the lowest point. Hold

a full tile there, with a 1/4-inch gap at the bottom and spacer at the top, and mark

it. Extend this line level on the wall.

All right, next you'll want to see where the top tile will sit. Try this trick.

Take a straight board and mark it using the tiles and spacers in the vertical layout.

This is called a jury stick. Just hold it up to the wall to mark the location of the

top tiles.

If you need to adjust the layout, move it down if you can. Cutting a little bit off

the bottom row won't be noticeable. Once you have a good layout, extend your starting

line along each wall.

OK, got all that? Our layout is set, which means it's time to install some tile on this

wall. Check out the next video, How to Install Shower Wall Tile at Lowes.com/HowTo.
