How to Set Marble Tiles in a Shower
- 1). Spread wall mortar on the shower's walls and floor with a trowel, checking periodically with a level to ensure a smooth surface. Allow the wall mortar to dry completely.
- 2). Spread a small amount of thinset mortar at the bottom corner of one wall, using the notched trowel. Only spread as much as you'll use in 15 minutes.
- 3). Apply one row of tiles to the mortar, leaving a 1/16-inch space in between for grout. Place a long piece of scrap wood over the tiles and gently beat them into place with the rubber mallet.
- 4). Apply the tile upward and outward until you reach the shower wall and floor edges.
- 5). Measure the remaining space of the shower wall edges, using a tape measure. Cut tiles to fit the spaces, with a lubricated table saw. For small tiles, cut with tile nippers.
- 6). Mix the grout and spread it with a trowel into the spaces between the tiles. Clean excess grout off the surface of the tiles with a wet sponge. Allow the grout to dry.
- 7). Apply a marble sealer to the tile and grout with a clean rag. Allow it to dry and buff with another clean rag.
