Bathrooms fail on moisture first and looks second. Ventilation, waterproofing and slip-safe floors are the invisible design decisions that decide whether a bathroom still looks good in five years — tile and taps are the easy part.
Plan extraction and storage before you fall in love with a tile: a fan sized to the room, a niche in the shower, and a vanity with drawers instead of doors will improve every single day you use the room.

Pro Tips That Make the Difference
Ventilate like you mean it
Fit an extractor rated at least 1 CFM per square foot (50 CFM minimum) on a timer that runs 20 minutes after showers. It prevents the mould that ruins grout and paint.
Store inside the walls
A shower niche and a mirrored cabinet put storage where you use it and keep the vanity top clear — the difference between spa and cluttered.
Choose tile by grip, not just looks
Use matte or textured tiles (high slip resistance) on floors, large formats to reduce grout lines, and keep gloss for walls only.
Layer light at the mirror
Vertical lights at face height on both sides of the mirror remove shadows; a single overhead light ages every face by ten years.
Mistakes to Avoid
- No extractor fan, or one too weak for the room
- Glossy polished tile on a wet floor
- Painting with standard emulsion — use bathroom paint rated for steam
Bathroom Design — Frequently Asked Questions
What makes a bathroom feel like a spa?
Warm layered light, one natural material (wood-look tile or a teak stool), plants that tolerate humidity, thick towels in one calm color, and everything else hidden in closed storage.
Are large tiles better in a small bathroom?
Yes — fewer grout lines make the room read bigger. Use large tiles on walls and slightly smaller, grippier ones on the floor.
Which paint finish survives bathroom steam?
A dedicated bathroom paint or satin/eggshell with mould resistance. Flat matte chalks and peels in daily steam.
