Before laying the bathroom tiles, start by removing your old carpet and carpet strips. Use a cutoff saw to make room for the bathroom tile to slip under the doorjambs. Place a portion of the tile pattern starting at the doorway to set up a centerline and then strike a chalk line.
Cut the bathroom tile with a wet saw or tile snips. Work your way up one side of the room and down the other. Allow 1/8" for grout lines; spacers can be used for consistency. Mix the thinnest using an electric drill with a mixing bit.
Mix small amounts at a time, adding water slowly to maintain the right consistency. Mix enough to lay down a dozen or so bathroom tile at once, and be ready to go to work as the thinnest dries quickly using a trowel to apply the thinnest to the floor.
When the bathroom tiles are all in place and some-what dry, use a grout saw to scrape the excess thinnest out of the joints where the grout will go. A shop van will clean most of this up, but use a wet sponge to get the surface clean. Once dry, begin applying the grout with a rubber trowel.
One more sponge cleaning will be required to get up the film once the bathroom tiles is dried completely. It's recommended to apply a grout sealer after about 48 hours or so to help avoid any staining problems that occur during normal use.
