To tile a bathroom floor, follow these key steps for a professional and durable finish:
Preparation
- Assess and prepare the subfloor: Ensure the subfloor is flat, level, and free of damage. Replace any damaged areas and use a leveling compound for minor dips
- Remove existing flooring if necessary: Tiles can sometimes be laid over concrete or laminate floors if in good condition, but hardwood usually requires removal or a backer board for leveling
- Install an uncoupling membrane: This helps prevent cracking and waterproofs the floor. Cut the membrane to size and adhere it to the subfloor with thinset mortar, allowing it to cure for 24 hours
Planning and Layout
- Measure and plan tile layout: Snap chalk lines to mark the center and main reference lines. Dry-fit tiles starting from the center to ensure even cuts and a balanced look, avoiding small slivers of tile at edges
- Adjust layout to minimize cuts: Aim to use full tiles in visible areas and cut tiles no smaller than half their size
Tiling Process
- Mix thinset mortar according to instructions.
- Apply thinset: Use a notched trowel to spread thinset evenly on a small section of the floor and also back-butter the tile backs for better adhesion
- Lay tiles: Press tiles firmly into the thinset with a slight twisting motion. Use tile spacers between tiles to maintain even grout lines and a tile leveling system to keep tiles flat and level
- Cut tiles as needed: Measure spaces along walls or door jambs, mark tiles, and cut with a tile cutter or saw. Smooth edges with a tile file
Finishing
- Clean excess thinset: Wipe away thinset from tile surfaces and grout lines before it hardens using a damp sponge and tools like toothpicks or thinset removal tools
- Allow tiles to set: Let the adhesive cure for at least 24-48 hours before walking on the floor or applying grout
- Grout the tiles: Once set, remove spacers and apply grout with a grout float. Clean grout haze from tiles after it dries and seal grout if recommended
Tools and Materials Needed
- Tiles, thinset mortar, grout, tile spacers, tile leveling system
- Notched trowel, rubber mallet, tile cutter/saw, tile file
- Sponge, bucket, chalk line, measuring tape, gloves, safety gear
Following these steps carefully will ensure a well-laid, durable, and attractive bathroom tile floor
