Things You'll Need

Instructions

1

Mark diagonal lines from one corner to the other on two tiles to divide them into triangles.
2

Cut the tiles along the lines with a tile scribe. To cut a tile, place a straightedge against the line and score the tile, applying firm pressure. Place a taut, straight wire under the tile, aligned with the cut. Push down on either side of the tile to snap it.
3

Create two triangular wood blocks to accommodate the tiles. Create triangular blocks by cutting a square out of a thick piece of wood. Make the square 3/8-inch larger in both directions than the tiles. Cut the square down the middle to make two triangles. Sand the cut ends.
4

Measure the cut side of one of the blocks. Cut two rectangular tile pieces to fit the dimensions, using the scribe.
5

Apply mortar to the backs of the tile. Rough up the mortar with a fork and stick the tiles onto the tile, leaving the square sides of the blocks bare. Allow the mortar to harden.
6

Adhere the tiled blocks in the corners of the tub, using construction adhesive. Allow the construction adhesive to dry.
7

Spread grout into the spaces between the tubs. Wipe the splash guards down with a damp sponge to remove any excess grout. Wait for the grout to dry.
8

Run a bead of caulk along the seam where the splash guard edges meet the tub. Run a finger down the caulk to smooth it down.
9

Allow the grout to fully cure then paint it with grout sealer.
