How to Make a Tile Baseboard

Determine the desired height of the tile baseboard from the floor up the wall. Transfer this measurement to one wall's right end, left end and centered between the two marks. Connect all three marks with a chalk line and snap it to leave a level chalk line across the wall, indicating the tiles' top edge. Repeat with the remaining walls.

Transfer the height measurement from Step 1 to a tile. Lay the tile on a tile cutter. Drag the carbide wheel over the tile's front surface, to score a line where you want the tile to break. Center the carbide wheel's back edge over the tile and press down to snap the tile along the score line.

Place a tube of construction adhesive in a caulk gun and cut off the tip with a utility knife. Flip the cut tile over and squeeze a bead of adhesive along the back in a wavy line. Slide the tile up to the wall, still flipped over, with the edge you cut touching the wall.

Lift the tile up and press it flat against the wall. Wiggle it back and forth slightly so it forms a tight seal against the drywall. Adjust the tile so the top edge lines up with the chalk line you made in Step 1.

Prepare a second tile the same way you prepared the first tile, by following Steps 2 and 3. Place the tile's cut edge against the wall. Leave a slight gap between the first tile and the second tile, to be filled with grout. The gap's width depends on the grout gap you used for your tile floor. Aim to match up the baseboard's grout lines as closely as possible with the flooring's grout lines. Continue to install tiles all the way around the room.

Mix grout with water according to the manufacturer's directions. Let the mixture sit for 10 minutes and stir it again. Apply the grout to the tile baseboard with a grout float. Fill the gaps between the tiles with grout and scrape any extra grout off the tiles' surface. Apply the grout to only one wall's tile baseboard.

Dip a sponge into a bucket of clean water. Wring the sponge out so it is damp. Wipe the sponge over the baseboard tile in a circular motion to clean the tiles' surface. Rinse the sponge often.

Apply grout to a second wall and wipe it with a sponge. Repeat with the third and then the fourth wall.
