Astro Dio Bathroom Wall Light

The Astro Dio Bathroom Wall Light is a slim, minimalist LED bathroom fitting from Astro, finished in polished chrome and designed for reliable, moisture-resistant performance in bathroom settings.

Its long, tubular form uses a frosted opal diffuser set between matching metallic end caps, with a central rectangular wall plate for a discreet, balanced appearance. The fitting is finished in polished chrome and presents a restrained, architectural profile that works quietly alongside contemporary or pared-back interiors.

Constructed from metal with a frosted diffuser, the Dio conceals wiring and fixings behind the mounting plate and uses symmetrical end caps to create a neat, finished look. The product is Class II double insulated and supplied with a three-year manufacturer warranty.

The integrated 3.6W LED delivers an even, continuous glow along the length of the tube; the frosted diffuser moderates glare and provides soft, diffused illumination. The LED has a CRI of 80, making this fitting suitable for ambient or vanity-adjacent lighting in bathrooms.

The fitting is IP44 rated and suitable for installation in bathroom zones 2 and 3. It mounts to a vertical wall via the central plate; as a Class II appliance it does not require an earth connection. Check technical notes for dimming compatibility where required.

At Lighting Design Online we recommend the Dio when you need a focused, low-profile bathroom wall light that resolves into the scheme rather than shouting for attention. Our guidance helps specify the correct protection, placement and finish so the fitting performs as intended while delivering a considered, long-lasting outcome backed by professional assurance and clear technical support.
