Slate is an old favorite for home construction; building a slate shower floor or wall is no exception. The tiles typically come in 12x12-inch inch dimensions. Since the tiles are this, the amount of time it takes to install them is not as great as with other materials. When installing a slate shower floor, be sure to choose the right sort of tile. The material should be moisture resistant and slip-proof.
Step 1 - Take the Measurements
Determine the exact center point of the floor by running a straight line along the floor connecting 2 opposite corners and another line connecting the other 2 corners. The cross in the middle will mark the center of the floor. Start tiling from the center of the room. In irregular floor spaces, you may find that it is easier to start tiling from the corner of the room.
Step 2 - Lay the Tiles on the Floor
Do not apply adhesive to the floor or tiles at this point. They should be placed onto the level floor. Place the tiles from the center point and work your way outwards. Use the tile spacers between the gaps. They are typically small plastic crosses which you use between the tiles to mark the gaps for grout. Lay the tiles carefully. When you reach the edges of the room, you will have narrow gaps which require tiles to be cut to fit. Determine how many tiles you need to cut. Set them aside, but do not cut them yet.
Step 3 - Fix the Tiles in Place
Mix the tile adhesive according to the manufacturer's instructions. Do not mix more than you will use in 30 minutes. Spread the adhesive on the floor with a trowel. Work in small sections, laying no more than 6 tiles at a time. Place a thin sheet of the adhesive onto the back of each tile before putting it in place. Use the tile spacers between each tile. Continue with each area of the floor in the same manner. When you reach the tiles that will be cut, mark the cut line on the underside of the tile and use a tile cutter to make the cuts.
Step 4 - Grouting the Tiles
Wait until the next day to grout the tiles. Apply sealant it to the cracks between the tiles, removing the tile spacers as you go. Clean excess grout with a damp sponge. Leave for several days before using the bathroom.
