tools and materials

  • Tile Caulk, sanded or non sanded depending on grout joint width
  • Tile piece or formed shower shelf
  • Thinset
  • Laytex modifier
  • Tile Saw

step 1 Sizing The Shower Shelf

The shelf can be any size you like as long as it can be cut out of a single tile.

  • 12 x 12 tiles work best for tile shelf because they create enough surface area for a nice sized shelf.
  • Use a tile saw to cut the tile at 45 degrees from corner to corner.

step 2 Placing The Shower Corner Shelf

There are two ways to set a corner tile shelf. Either on top of a course of tiles or in the middle of a tile.

Tile Shelf Height: The height of a tile corner shelf is purely arbitrary but the higher the shelf the less water gets splashed on it and if you are putting soap on the dish then the less water to make it soggy the better.

Location On The Tile Joint: Tile joints are the easiest and strongest location to set a corner shelf. Set the wall tiles to the height you want the shelf set at and place the tile on the top of the row of tiles.

Cutting The Next Row Around The Shelf: The row of tiles above the shelf will be custom cut to fit over the tile. This locks the tile in place giving the shelf more strength.

step 3 Attaching The Tile Shelf

  • The best adhesive to use is cement based tile thinset mixed with a liquid laytex modifier.
  • Use the same thinset or tile adhesive you used to install the wall tile.
  • Place enough adhesive on the tile surface that will touch the wall to thouroughly embed the tile without spilling out around the tile.
  • Make sure there is a slight slope from the corner to the outer edge of the shelf so water will run of the shelf.

step 4 How To Grout Shower Corners

Grouting shower corners requires the use of a sanded or non sanded caulk, depending on the size of your grout joints. Any corner in a shower is a place where the two joining surfaces will move in different directions. Regular cement grout will crack because it cannot flex. Using a caulk in the shower corners keeps water on the right side of the tile which extends the life and good looks of your shower. Grout manufactures make a sanded and non sanded caulk that is the exact color of the grout they sell.

  • Use non sanded grout or grout caulk for grout joints of 1/8" or less. Grout joints larger than 1/8" need sanded grout to help strengthen the grout.
  • Cut the end of the caulk tube so that it puts out a bead of caulk that is 1/8" round.
  • Start at the end of a joint and apply caulk as far as possible. Keep the caulking gun moving at a constant speed.
  • Use a wet finger to press the caulk into the joint creating a good seal and to smooth the top of the caulk.
  • Let the caulking dry
