Craftsman Trade Advice

Essential technical rules from master tilers for durable tile installations.

Waterproofing

Waterproofing & Substrate

Apply a liquid waterproofing membrane or sealing slurry directly under the tiles, with perimeter sealing tape along all wall-floor transitions. Around walk-in showers, ensure a continuous 2% drainage slope toward the drain before applying adhesive.

Sightline

Starting Axis & Sightline

Align your primary tile axis starting from the bathroom door threshold. Full tiles should greet you when stepping in, pushing narrow cut tiles to less visible zones under the vanity or behind the toilet.

Expansion Joint

Flexible Perimeter Joints

Never grout floor-to-wall transitions with rigid cement grout. Use sanitary silicone with a closed-cell backer rod to absorb building deflection, prevent moisture ingress, and protect edge tiles from cracking.

Frequently Asked Questions

How much tile waste should I calculate for a bathroom?
For a standard bathroom, calculate 12–15% waste rather than the usual 10%. Bathrooms feature extensive cutting around toilet flanges, shower drains, radiator pipes, and door frames, which generates higher offcut scrap.
Which tile size makes a small bathroom feel larger and more open?
Large format tiles such as 60×60 cm or 60×30 cm visually expand small bathrooms. By minimizing the number of grout joints, the floor surface appears calm and unified rather than divided into a busy grid.
Should floor tile joints align with wall tile joints in a bathroom?
Continuous joint alignment between floor and wall creates a harmonious, architectural look if tiles share exact dimensions (such as 60 cm). If wall and floor tiles differ in size, choose an offset layout on the wall to avoid discordant near-alignments.
How do I tile around a walk-in shower tray in a bathroom?
Maintain a consistent 3–5 mm expansion joint between the shower tray rim and surrounding floor tiles. Fill this joint with sanitary silicone instead of cement grout to absorb temperature expansion and tray deflection.
