Bathroom lighting has to do more than one job at once: bright enough for shaving or make-up, gentle enough for a relaxing soak, and safe enough for a room full of water and moisture. Getting the balance right takes a mix of fixture types, not just one.

The importance of bathroom lighting

Good bathroom lighting balances three things:

• Overall illumination

• Precision task lighting for shaving or make-up

• Gentler lighting for relaxation

Getting this combination right makes the space both practical and inviting.

Types of bathroom lighting

Bathroom lighting splits into three categories, and most well-lit bathrooms use a blend of all three.

1. General lighting

Keeps the whole bathroom well-lit:

• Downlights: recessed spotlights giving widespread illumination

• Directional spotlights: good for ambient lighting or picking out design features

• Flush ceiling lights: sit flush to the ceiling rather than recessed within it, giving a gentle glow

• Pendant lights: a decorative option for larger bathrooms

2. Task lighting

This is what you need for precision tasks, like shaving or doing your make-up:

• Wall lights: positioned either side of the mirror for even illumination, better than a downlight directly overhead, which casts shadows across your face

• Integrated mirror lights: LED lighting built into the mirror itself, cost-effective and space-saving

3. Accent lighting

Creates ambience, aiming for something closer to a spa than a clinical exam room:

• LED strip lighting: flexible and waterproof, good under cabinets, shelves, or around the base of a bath

• Niche lighting: recessed lighting in shelving alcoves, both functional and decorative

How to choose the best bathroom lighting for your home

Style and design

• Modern bathrooms: chrome finishes and clean lines

• Sleek, minimalist looks: recessed spotlights and LED strips

• Traditional bathrooms: brass, antique bronze, or ornate designs

• Industrial feel: matt black paired with metallic accents

• Rustic settings: lantern-style pendants

• Spa-like ambience: under-cabinet, mirror, and niche lighting for soft, diffused light

Bathroom size

• Smaller bathrooms: flush or recessed lighting saves space; backlit mirrors work well too.

• Larger bathrooms: a pendant or even a chandelier can work, combined with recessed lights, wall sconces, and accent lighting for a fuller effect.

Colour temperature

• Warm white (2,700-3,000K): creates a cosy, relaxed atmosphere.

• Cool white (4,000-5,000K): better suited to task lighting, particularly around a mirror.

Safety: IP ratings and bathroom zones

This is the one area where "buying guide" tips become genuine legal requirements. UK wiring regulations (BS 7671) divide bathrooms into zones based on proximity to water, each with a minimum IP (Ingress Protection) rating a light fixture must meet:

• Zone 0: inside the bath or shower itself. Fixtures must be low voltage (max 12V) and rated at least IP67 (fully submersible).

• Zone 1: the area above the bath or shower up to 2.25m high. The regulatory minimum is IPX4, but IP65 is standard practice, and any 240V fitting here needs 30mA RCD protection.

• Zone 2: up to 0.6m outside the bath or shower perimeter, and up to 2.25m high. Requires a minimum of IP44. It's also good practice to treat the 0.6m area around a sink as Zone 2.

• Beyond Zone 2: no specific IP rating is required by the regulations (the older "Zone 3" concept was removed from BS 7671), though an IP20-rated fixture is a sensible minimum for peace of mind.

Getting this wrong isn't just a style mistake. It's a genuine electrical safety and compliance issue. Always confirm the rating with your electrician before buying a fixture for a specific spot in the room.

Energy efficiency

LED is the standard choice. It uses up to 90% less energy than incandescent bulbs and lasts significantly longer.

LED bathroom fixtures often come with useful extras:

• Dimmable settings for mood lighting

• Smart control of timing, temperature, and brightness from an app

• Motion sensors that stop lights being left on, particularly useful at night

How much does bathroom lighting installation cost?

Cost depends on the scope of work, fixture type and quality, and installation complexity. Our downlight installation cost guide gives a current steer on supply-and-fit pricing. For an accurate quote for your specific bathroom, contact a qualified local electrician.

Before you head out to buy fixtures, run through this quick checklist.

Before you buy

• Map out which zone (0, 1, or 2) each fixture will sit in

• Confirm each fixture's IP rating matches or exceeds its zone's minimum

• Decide on colour temperature by area (task vs relaxation)

• Check dimmer or smart compatibility if you want that functionality

• Get a qualified electrician to install, and to confirm zone compliance before you buy

Key takeaways

• Combine general, task, and accent lighting for a bathroom that's both practical and inviting

• IP ratings tied to bathroom zones are a genuine safety requirement, not just a suggestion

• Always hire a qualified electrician for installation

• LED is the standard, most cost-effective choice for bathroom lighting today
