How to Enclose a Corner Bathtub

Measure one of the walls behind the tub, from end to end. Mark the middle. Draw a vertical line from the tub rim up the wall to the top at the middle, using a pencil and level.

Spread tile adhesive over the wall, from the rim up by more than the height of your tiles. You will still be able to see the vertical line through the adhesive.

Set the first course of tiles into the adhesive along the tub rim, starting at the middle line and working sideways. Put spacers between tiles and under them, to separate them from the tub rim.

Cut the tiles for the two ends of the course on your tile saw, as needed, to fit at the ends.

Spread more adhesive across the wall. Press the second course of tiles in place above the first, again beginning at the center line and building to the sides. Set spacers between the tiles. Cut around any plumbing fixtures as needed with the tile saw.

Continue working your way up the wall course by course, spreading more adhesive as needed. Cover the whole wall. Repeat for the other walls around the tub.

Let the adhesive set for 12 hours. Pull out the spacers.

Spread grout over each of the walls, starting at the top of each and scraping the long edge of the float over the surface to press it into the spaces. Wipe up the excess grout with a dampened sponge.

Let the grout set 24 hours. Run caulk along the joints where the tiles meet the tub rim and the walls meet each other. Let the caulk set 24 hours.
