Bathroom floor tile selection involves safety requirements that don't apply in other applications.
Bathroom Renovation Essentials
Bathroom floor tile is a functional material selection before it's an aesthetic one. The safety requirements for wet floor surfaces constrain design choices in ways that other flooring decisions don't.
Slip resistance is the primary functional requirement. Tiles are rated for slip resistance by their DCOF (Dynamic Coefficient of Friction). Tiles with DCOF above 0.42 are generally suitable for wet floors. Smaller tiles and matte or textured finishes typically offer better grip.
Design Choices That Matter
Grout joint density improves traction. More grout joints provide more texture for foot grip. Mosaic tiles (small tiles with proportionally more grout) are inherently slip-resistant because of the dense joint pattern — a reason they're traditional in shower floors.
Large-format tiles (600mm and larger) are increasingly popular for bathrooms. They're sleek and modern, with fewer joints to maintain. On floors, they require excellent subfloor flatness to prevent rocking and edge chipping.
Hiring the Right Contractor
Porcelain versus ceramic: porcelain is denser, absorbs less water, and is more durable. For bathroom floors, porcelain is the preferred material — particularly in high-use bathrooms. Ceramic is acceptable for low-use secondary bathrooms.
Grout selection: sanded grout for joints 3mm and wider; unsanded for narrower joints. Epoxy grout is the most stain and moisture resistant option for bathroom floors — higher cost is offset by dramatically lower maintenance requirements.
Colour considerations: darker grout hides dirt and stains; lighter grout brightens the floor but requires more maintenance. Matching grout to tile colour creates a monolithic appearance; contrasting grout emphasizes the tile pattern.
