Installing glass bathroom tiles on the ceiling is the same as installing tiles on the floor or wall. Here is a step by step guide to install glass bathroom tiles on the ceiling.

Step 1 - Attach Substrate

A substrate is a plane between the tile and the surface, or in this case, the ceiling. It is not recommended to install glass tiles directly to wood substrates. Measure and cut the substrate according to the size and shape of your ceiling. Then attach the substrate to the ceiling using drywall screws and a power drill. Drill into the ceiling beams.

Step 2 - Apply the Setting Materials

Any good grade and flexible mortar system is recommended. Mix the setting materials according to the manufacturers specifications. Using a 3/16-inch square notched trowel, apply the setting materials to the substrate. Smooth the trowel ridges using the flat before setting the tile. Apply a thin layer of the setting material to the back of the tile as well.

Step 3 - Place the Tile Where It Needs to Go

The beveled edge of the tile is placed into the setting material; the larger area of the tile is facing you. Leave 1/16-inch between each tile. Gently press the tile into the setting material using a rubber float or equivalent tool. Be careful not to press down too hard, as the setting material will begin to fill the gaps of the tile. Adjust the tiles to level them and create even spaces. Wipe the tiles with a damp sponge to remove excess setting material.

Step 4 - Grout the Tile

Wait 24 hours before applying grout. Mix the grout according to the manufacturer’s specifications. If the joints of the tiles range from 1/16-inch to 1/8-inch, then use non-sanded grout. If the joints are larger than 1/8-inch, use sanded grout. Follow the manufacturer’s instructions to grout the space between the tiles. Wipe the tiles with a damp sponge to remove excess grout. Caulk the joints on the corners where the walls intersect.

Step 5 - Cut Glass Tiles When Necessary

Depending on the size and shape of your ceiling, your glass tile will need to be cut. Use a wet saw and a diamond rimmed blade for glass tiles. Push the tile into the blade slowly. Smooth the edge with a diamond hand pad, dressing stone, or tile blade. If you need to drill holes, use a diamond core bit and a power drill on low speed. To prevent the tile from cracking, continuously mist the tile and power bit. Drill holes 1/8-inch larger to prevent stress transfer to the tile if anything is being attached with anchoring bolts.
