Sky-blue mineral plaster, one backlit timber slat wall and a ribbon of clerestory glass: a bathroom designed around daylight and a single warm centre.
The idea behind it
The scheme is a study in one warm object inside a cool field. Blue plaster wraps the entire volume; the slat panel provides the sole warm note, and the eye returns to it the way it returns to a fire. Rooms with one temperature contrast feel deliberately designed.
Continuous finishes — same plaster all round, same grey stone floor — erase the visual borders between bathing, washing and showering, so a normal-sized room reads as open-plan architecture.

Steal the look
Step 1
Finish all walls in sky-blue limewash or mineral paint, ceiling kept white to lift the light.
Step 2
Build the slat panel floor-to-ceiling at the room's focal centre, routing two niches with LED backlight.
Step 3
Place the white oval tub before the panel on a woven mat, filler mounted on the slat wall.
Step 4
Hang the floating stone vanity with two black-framed soft-rectangle mirrors and slim sconces.
Step 5
Fit the frameless shower along the far wall in tone-matched grey porcelain.
Step 6
Keep hardware exclusively matte black and slim in profile throughout.
Step 7
Layer light: bright neutral downlights for morning, niche and cove glow at 2700K for evening scenes.

Frequently AskedQuestions
Yes, outside the direct wet zone: sealed hardwood or quality wood-look slat panels handle bathroom humidity well with ventilation. For inside showers, use wood-effect porcelain planks instead.
Grey-washed powder blues pair beautifully with honey and oak timbers — the grey undertone keeps the combination sophisticated rather than nautical. Test large swatches beside your wood sample.
Pale matte walls, a large mirror opposite the light source, glass shower panels instead of curtains, and layered artificial light — bright 4000K for mornings, warm 2700K scenes for evenings.
