Lay out a single horizontal and vertical row of tiles design across the floor along the chalk reference lines. Shift the tiles, if needed, so any cuts that must be made by the wall are against the least noticeable wall tiles. You also don’t want cut marble tiles at the entrance to the bathroom, so adjust the wood tiles so cuts are against the far marble wall tiles. You can snap additional chalk reference lines, once the tiles layout is finalized, if you wish.

Set the first tile in the far corner of the room and work towards the doorway. You won’t want to step on the newly laid tile before the mortar has a chance to dry. Work on laying the tiles in small sections at a time. Mix up a small batch of thin-set mortar and spread a thin layer on the cement board with the notched trowel. Lay several pieces of cement tiles with tiles price spacers to establish even grout lines. Firmly press the tiles into the mortar so there are no air bubbles underneath.

Remove the excess grout from the surface of the tiles before it has a chance to dry. Fill a second bucket with water and use it to wet the large sponge with rounded corners. Wring out the sponge and then wipe over the tiles so that you are moving at a diagonal to the grout lines. If you wipe parallel to the grout lines, you might gouge out some of the grout and leave an uneven surface. Rinse the sponge in the bucket of water and repeat until all the grout is removed from the surface of the tiles.

Wait at least 2 days for the grout to cure before sealing it. Sometimes its smart to leave a humidifier on during the two days you’re letting it sit, to help the grout gain in strength.
