How to Add Backsplash to a Bathroom

A tiled backsplash can add a beautiful finishing touch to your bathroom. Whether you want to install a backsplash behind your sink, above your shower, or along your wall, doing so only requires a few tools and some time. Here, our bath solutions experts explain how to do it:

What you’ll need to add backsplash to a bathroom:bath solutions

  • Backsplash tiles
  • Measuring tape
  • Masking/painter’s tape
  • Mastic adhesive
  • Notched trowel
  • Tile cutter/saw
  • Grout, grout float
  • Damp sponge
  • Silicone sealant
  1. Before you begin, determine the pattern you want to make using your tile pieces.
  2. Turn off the power to the bathroom.
  3. Remove any outlet covers or switch plates that are in the area to be tiled.
  4. Use your measuring tape to measure and mark off the area you want to tile.
  5. After that, run masking tape or painter’s tape along the marked-off area to provide a stopping point for the backsplash.
  6. Next, spread a large dollop of mastic adhesive along the wall using your notched trowel.
  7. Use the trowel to spread it evenly both vertically and horizontally. (Make sure to leave an area dry at the top for your bull-nose tiles.)
  8. Then, beginning in the center, place your first tile at the bottom of the area to begin your first row.
  9. Continue placing tiles side-by-side to the left and the right until you reach a corner.
    1. If the last tile piece doesn’t fit for the row completion, you’ll need to cut it using a tile cutter or saw.
    2. When you put the cut pieces in place, install them with the cut corners facing the wall for a more flush look
  10. Next, complete the second row above the first row and continue until you’ve reached the top of the adhesive.
  11. Spread a small dollop of adhesive on the back of your first bull-nose tile and place at the top of your backsplash. (By doing this instead of placing it right on the wall, you won’t have to worry about too much adhesive on the wall.)
  12. Allow the mastic adhesive to dry completely.
  13. Next, mix up your grout and spread it evenly over your tiles using your grout float.
  14. After that, wait for the grout to set into a powdery film and wipe off the excess with a damp sponge.
  15. Using silicone sealer, fill in any gaps between the backsplash and your shower enclosure, sink, or countertop.
  16. Replace your outlet covers and/or switch plates (you may need to install box extenders so that they sit flush.)
