Step 1: Measure Your Space

The first step is to determine your layout. Sketching the dimensions of the shower will help you figure out what you want to do — and what works for your particular situation. Computer programs are available that can create 3-D images that will give you an idea of what your finished shower will look like.

Make sure you can access the pipes behind your shower. Then, measure the shower to make sure you have enough space for the system you want to install.

Step 2: Take Out the Old Showerhead

Collect the tools and materials you will need for the job. If your new unit is heavy, get someone to help with the lifting.

Cut off the water supply and remove the old showerhead.

Step 3: Remove the Old Tile

Use a rotary tool to grind out the grout (Image 1).

Score the tile and hit it with a cold chisel to crack the tile (Image 2). Since the grout has been removed, you do not need to worry about cracking the rest of the tiles.

Remove the tile and the leftover thinset. You can scrape the old thinset off using a 5-in-1 tool and a hammer (Image 3). The area where the old tile was located needs to be leveled so the new tile will not stick out.

Step 4: Lay the New Tile

Then spread thinset on the back of the new tile. Place 1/8" spacers so that all of the grout lines remain the same. After the thinset has dried, remove the spacers and then apply grout with a rubber float. The key here is to turn the float at an angle and spread the grout across the joints.

When the grout sets, but is not too dry, wipe off the excess with a damp sponge.

Tip: If you don't have enough matching tile for your particular repair job, think about removing additional tiles in a decorative pattern and replacing them with tiles in contrasting colors.
