Tile Selection for Bathrooms: From Floor to Wall to Shower

Tile selection is one of the most complex decisions in bathroom renovation. Here's a systematic guide.

Bathroom Renovation Essentials

Bathroom tile selection involves multiple surfaces, each with different functional requirements, visual roles, and sizing considerations. Approaching it systematically produces a cohesive result rather than a collection of individually chosen materials.

Floor tile must be slip-resistant when wet. Tiles with a COF (coefficient of friction) rating above 0.50 are considered safe for wet floor applications. Smaller mosaic tiles provide more grout joint texture, which improves grip.

Design Choices That Matter

Shower wall tile requires water-resistant installation regardless of tile type. Large-format tiles (300x600mm and larger) have fewer grout joints, which means fewer potential water entry points and easier cleaning.

Grout joint width affects both appearance and function. Large-format tile typically uses 1.5-2mm joints; smaller tile uses proportionally wider joints. Non-sanded grout is for joints under 3mm; sanded grout for joints 3mm and wider.

Hiring the Right Contractor

Rectified tile (cut to precise dimensions with minimal variation) is required for large-format installations and for achieving minimal grout joints. Non-rectified tile has more size variation and requires wider joints to accommodate it.

Coordinate floor and wall tile selections. They don't need to match, but they should relate — through shared colour family, complementary scale, or consistent tone. An unrelated floor and wall tile combination creates a disjointed appearance.

Finish selection affects appearance and maintenance. Polished tiles show fingerprints and water spots readily; honed and matte finishes are more forgiving. Highly textured tiles are more slip-resistant but harder to clean. Match finish to both aesthetic and practical requirements.
