Coastal Bathroom Ideas
Coastal interiors borrow their palette from the shoreline rather than from nautical decor — sand, driftwood, sea glass and bleached linen instead of anchors and rope. The defining move is light: pale surfaces bounce daylight around, and window treatments stay sheer so the view does the decorating. Materials look weathered on purpose, as if salt air has already softened them.
Applied to the bathroom, this style works best when the layout fundamentals are right first. Bathrooms reward continuity: run one tile or stone across floor and wet walls to make a small space read larger, and put niches in the shower instead of shelves. Lighting at the mirror should come from the sides or a backlit panel — a single overhead light casts unflattering shadows.
The Coastal palette
- Bleached oak, driftwood and rattan in matte, open-grain finishes
- Off-white and sand walls with sea-glass green or faded indigo accents
- Washed linen, cotton slipcovers and jute underfoot
- Unlacquered brass or aged nickel that is allowed to patina
- Sheer curtains and unobstructed daylight from every opening
Bathroom planning tips
- Use large-format tile with minimal grout lines to enlarge the space
- Light the mirror from both sides, not just above
- Build a recessed niche into the shower wall for storage
- Add a heated towel rail or underfloor heating for daily comfort
