In today’s interior design trends, aluminium is becoming the go-to material for modern bathrooms. I’ve personally found that small spaces often push creativity further – lighter, reflective surfaces, and multi-functional elements really stand out. In this article, I’ll share 10 aluminium bathroom design ideas, blending my own project experiences with expert insights, to help you make the most of your space.

Aluminium-framed shower enclosures

My Take: I’ve used aluminium frames in compact bathrooms to maximise transparency and minimise visual clutter. They give a sleek, modern look that feels airy.

Cons: Fingerprints and water spots can be more visible on shiny aluminium, so they require regular cleaning.

Tip: Opt for matte finishes if you want less maintenance.
