Choose the Right Tile

Porcelain and ceramic tiles are most commonly used in bathrooms because they are water-resistant and easy to clean. Make sure to pick a tile that has a rating of at least 3 on the MOHS hardness scale so it stands up to frequent use and cleaning. Smaller tiles like mosaics create a classic, elegant look but require more grout lines which can get dirty. Larger tiles are faster to install and have fewer grout lines to clean. Measure your space and create a layout before purchasing tiles to ensure you buy enough.

Prepare the Surface

Proper surface prep is crucial for tiles to adhere correctly. Thoroughly clean the installation area and remove any old adhesive or flaky paint. The surface should be smooth; fill any holes or divots with spackle and sand smooth. Seal porous surfaces like cement board to prevent moisture absorption. Apply a primer coat to create a uniform surface the thinset can grip.

Use the Right Tools

Investing in high-quality tiling tools will make installation easier and produce better results. A tile cutter will cut tiles neatly and precisely. Tile spacers keep grout lines uniform. A notched trowel creates the right depth and pattern for the thinset mortar. A grout float presses grout evenly into joints. Have a bucket for mixing thinset and plenty of clean rags on hand.

Apply Thinset and Tiles Correctly

Follow thinset package directions to mix it to the right consistency. Apply it to the surface using the notched side of the trowel held at a 45-degree angle. Only cover as much area as can be tiled before the thinset dries. Place tiles firmly in position, using spacers to maintain even grout lines. Push down on tiles to set them into the thinset. Check for 100% coverage by lifting a tile periodically.

Grout Application Tips

Let thinset cure fully before grouting, usually 24-48 hours. Apply grout using a rubber grout float, pressing it deeply into joints. Hold the float at a 90-degree angle and wipe diagonally across tiles to remove excess. Clean grout haze with a damp sponge. Use as little water as possible. Let grout cure fully before using shower, usually 72 hours minimum.

Caulk Critical Areas

Caulk where tile meets the tub, thresholds, changes in plane, and movement joints like where tile meets drywall. Silicone caulk withstands bathroom moisture better than grout in these spots. Smooth caulk with a finishing tool for a neat look. Allow caulk to cure fully before exposing it to water.

Seal Grout and Tile

Applying grout sealer protects grout from stains and moisture. It’s easiest to seal grout shortly after installation. Re-seal grout annually. Use a sealer formulated for porous tiles like natural stone as well. Do not seal pre-sealed porcelain or ceramic tile. Check manufacturer recommendations.

Maintain Your Tile

Sweep or vacuum tile floors regularly to prevent dirt buildup. Use a pH-neutral cleaner designed for tile and grout. Re-caulk when cracked or missing in high moisture areas. Address any loose or cracked tiles immediately to prevent damage to surrounding tiles. With proper installation and maintenance, you can enjoy beautiful tile in your bathroom for decades.

FAQs about Tiling a Bathroom

What size tile is best for a small bathroom?

Smaller mosaic tiles (2 inch hexagons or 1 inch squares) help a small bathroom feel larger by making the space seem more expansive. Larger tiles (8 inches or more) tend to make a small bath feel closed in. Aim for tiles in the 4-6 inch range for optimum effect in small baths.

What’s the minimum tile thickness for bathroom walls?

Tile should be at least 1/4 inch (6mm) thick on bathroom walls. Thicker tiles provide more durability and strength. Use extra care handling thinner mosaic tiles during installation to prevent cracking, chipping, and breaking.

Should bathroom floor tile go under toilets?

Yes, tile should run under the toilet flange and fully across the bathroom floor. Leaving exposed subfloor under the toilet just leaves rot-prone material exposed to moisture. Completely tiling under toilet flanges results in a clean, seamless look.

Is small bathroom wall tile laid out vertically or horizontally?

Vertically stacking rectangular wall tiles in a small bathroom helps walls appear taller. Horizontal lines tend to make small bath walls look busier. Stack tile with the long side vertical, or do a classic brick-laid pattern with subway tile. Keep grout lines minimal.

Should bathroom tile go all the way to the ceiling?

Tiling from floor to ceiling makes a bold design statement and removes the need for caulking where tile meets the ceiling. If not tiling to the ceiling, tile should at least extend 4-6 inches above showerhead height. Use durable waterproof drywall above the tile as needed.

How long does bathroom tile installation take?

For an average sized bathroom, expect professional installation to take 2-3 days. Showers or intricate tile layouts take more time. Doing it yourself generally doubles the timeline. Factor in extra time for tile prep work, setting, mortar curing, careful grouting, and sealant application. Rushing the job can result in major mistakes.

Conclusion

With thoughtful planning and preparation, tiling a bathroom successfully is an achievable DIY project or a task for a qualified tile installer. Focus on proper surface prep, precision tile cutting, adequate thinset mortar coverage, careful grouting, and ample curing time. Use high-quality bathroom-rated tiles and installation materials for best results. Protect your efforts with grout sealing and proper maintenance. A well-tiled bathroom is a space you can enjoy for decades to come.
