Step 1: Prep the Floor

If your home only has one toilet, you can keep it until you install the backer board. And you also should prepare the wax rings on hand if you plan to reinstall the toilet at the end of each day. If you are not to keep the toilet, you need to stuff a rag in the hole to block the sewer after disassembling the toilet.
As for the vanity, if you want to keep the vanity for later years, you can leave it and tile around it. If not, you can remove the old vanity and reinstall the old vanity or put in a new one.
Pull off the baseboard or plan to add base shoe molding. It would make the job neater because the edge of the tiles can be covered. In other words, the cut edge of the tiles and slightly measuring mistakes are hidden.

Step 2: Install the Uncoupling Bathroom Tiles Membrane

In this step, you need to transfer the size of the bathroom flooring porcelain tile to the off-size uncoupling tile membrane by tape measure and marker on the membrane with an indelible marker. After that, you should cut the membrane and prepare the subfloor by skimming out unmodified thin-set grout. When the membrane is pressed into the still-wet thinset. Then, you need to wait FOR 24 hours for full bonding of the membrane.

Step 3: Design the Tile Layout

This is the most important part to determine the style of your bathroom. According to the size and style of the bathroom, you need to use the chalk to strike a line down the center of the room and determine the center point with a tape measure.

Step 4: Dry Layout
This step is to make sure the following job is right and exact. You need to lay out the tile from the centerline outward. Ideally, the most visible sections of the floor should be covered by full-size and uncut tiles. Firstly, in order to have equal spaces along walls that face each other, you need to center rows of bathroom floor tiles between walls. Second, set the two rows parallel to the two most prominent walls.

In this step, you should manage to complete the following goals:

1. Can use full-size tiles at doorways and along with the bathtub or shower
2. Avoid using narrow tiles along walls. In ideal, you just cut the tile to half size or larger.
3. Minimize cutting and try to avoid difficult cuts. For example, when an "L" shaped gap is less than 2-inch in width. It is difficult for you to cut. The L-shaped tiles usually tend to break off as you cut.

Step 5: Cut the Door Jambs

If you expect to leave the door jambs in place, you need to stack a piece of backer board, tile, and two layers of cardboard and raise the saw to the correct height above the door, and cut the door jambs. The cardboard should be above the tiles.

Tip: The height of cardboard space is equivalent to the height of the thinset mortar.

Step 6: Fill the Tile Membrane Cavities

Mix up the thinset in a bucket. Then, you can use the trowel to fill the membrane of the bathroom floor tiles. In this step, you should use the straight, un-notch side of the trowel, which could fill the membrane very well.

Step 7: Install the Bathroom Tiles with Thinset

In this step, you also need to spread mortar across a small section of the floor with the notched side of the trowel. This spreading is about 2 feet by 2 feet. After that, you also need to spread the thinset on the back of the tiles, like spreading the butter. After that, you should press the tiles onto the floor. You need to confirm the tiles for the floor bathroom are firmly stuck onto the floor. As you plan to progress to adjacent tiles, you should insert tile spacers.

Step 8: Apply Tile Grout

After the full set of the bathroom tile(about 24 to 48 hours), you need to mix the tile grout and apply it with the rubber grout float.

Step 9: Remove the Grout Haze

After the grout has cured, add grout haze remover to the bucket with cool water. Clean the grout haze from the tile surface with the tile sponge.

Step 10: Seal the Grout

After the tile has dried, apply grout sealer. This will prevent water from percolating through the tile seams and under the tiles.
