AI Bathroom Design

A bathroom is decided by four surfaces: floor tile, wall tile, vanity front and metal finish. Get those four in a coherent palette and the room works even if everything else is builder-grade. Get one wrong — usually the metal, mixing chrome tapware with a brushed brass mirror — and the whole room reads as a rental.

Ask for the materials by name rather than by style. "Large-format warm grey porcelain, oak vanity, brushed brass tapware, white walls" will produce a coherent room. "Modern bathroom" will produce a stock photo that happens to be your bathroom's shape.

• Match metal finishes across tapware, shower frame and mirror. This is the most common miss.
• Large-format tile on the floor makes a small bathroom read bigger; small hex tile does the opposite.
• A wall-hung vanity shows floor underneath, which adds visible square footage.

Small bathrooms are a lighting problem disguised as a space problem. A render made from a photo with the ceiling light on will look flat and slightly yellow no matter what tile you choose; the same room with mirror lighting and a bright shower glass will look twice the size. Ask for the lighting change explicitly — it costs nothing and it is the single biggest improvement available.

Beyond light: run the tile to the ceiling so there is no horizontal band to stop the eye, use a glass screen instead of a curtain, and keep the floor and wall tile the same colour family so the room reads as one volume.

Waterproofing, drainage falls, extractor capacity and the position of the soil stack are invisible in a render and decisive in reality. A render will happily put a walk-in shower where the floor cannot drain, or a freestanding bath where the joists will not take the weight.

Use the render for the four surfaces and the light, then take the layout questions to a plumber. If you are changing the layout at all, get the render approved first so you only pay for one set of drawings.
