How to Tile a Bathroom Floor


Tiling is a useful skill to master, as you’ll be able to save hundreds of dollars by doing the job yourself instead of employing a professional tiler. Changing your floor tile is an easy and inexpensive way to update the look of your bathroom and can be completed in a day. If you don’t know how to tile a bathroom floor, the process is relatively simple and quick to learn.


Before starting, you’ll need to measure your bathroom floor in order to determine how many tiles you need to buy. While you can buy extra packs of tile later if you’re running short, it’s always better to buy enough tiles to finish the jobat the start, to avoid color and pattern mismatches from different tile batches.


If the floor is not already level and even, you can improve the tiling surface by laying an under layer of cement board. This should be cut to fit the space with a circular saw, and attached securely to the sub-floor with screws.


Once you’re ready to start tiling, start by laying the tiles out on the floor, using spacers to make sure they are positioned evenly. Don’t start in one corner and work out as this can result in small slivers of tile along wall edges.


The best method is to line up rows of whole tiles, centered in the middle of the room so there is an equal space on each side between the row of tiles and the wall.


After you’ve achieved a grid of full tiles taking up as much space as possible in the middle of the room, it’s easiest to set these tiles first before measuring and cutting the tiles around the edges of the room.


Apply thin-set mortar in small areas with a notched trowel and lay only a few tiles each time, before applying more mortar. After setting the tile in place, press down and wiggle it slightly to ensure it is embedded firmly in the mortar. Make sure all the tiles are level and flat and not tipped so one corner or edge is higher than the rest.


When all the full tiles are set and the mortar has been left to harden for several hours, you can measure and cut the tiles for around the edges of the room using a tile saw. Holes for pipes can be drilled or cut with a hole cutter.


After all the tiles are positioned and set, the final step is to apply tile grout to all the gaps between the tiles. Remove all the spacers between the tiles before you begin and use a grout float to work the grout back and forth over the floor. Scrape off as much excess grout as you can before it starts to dry.


Once the grout has started to harden, wipe over the tile surface with a damp sponge to clean away excess grout. This cleaning process should be repeated a second time and any remaining residue from the grout can be easily buffed away with a dry cloth.


If you wish to protect the grout against corrosion and discoloration, you can use a grout sealer to finish. Some sealers can be applied the day after grouting, while others recommend waiting several weeks for the grout to fully cure and settle before sealing. Follow the instructions on the sealer you choose for best results.
