1. Assess your bathroom first

Before investing in any new lighting, think about the times of the day that you use the bathroom; the natural light levels it benefits from; window locations; and whether there are any obstructions to light outside, such as trees.

Always consider lighting once the location of fixtures has been finalised – think about the ambience you want to create and the features that you’d like to draw attention to, such as a bath or architectural details. Lay out a floorplan showing the location and dimensions of sanitary ware, doors and windows, as well as wall, ceiling and floor lights and switches, working closely with your electrician to find practical solutions for your space.

2. Layering bathroom lighting

No matter the size of your suite, multiple lights will always enhance the design. A combination of downlights, task lighting, accent spotlights and recessed styles will create a scheme to suit all needs, providing practical lighting for day-to-day tasks, low-level ambient light and illumination at night.

Aim to include two circuits on dimmers and one circuit to control a presence detector for automatic night lights. Consider linking your extractor fan to one of the circuits, too.

When designing a bathroom scheme, I like to include:

Task Lighting – to illuminate areas where you need good visibility, such as by the mirror or around the basin. Effectively placed task lighting will prevent eye strain and improve precision when applying make-up or shaving. Mount wall lights at eye level either side of a mirror to avoid shadows.

Downlights – to provide good ambient light with a comfortable level of brightness. Position them around the sides of the room instead of the middle to avoid shadows, and use them to enhance features such as a statement wallpaper or a towel radiator.

Don’t add a downlight directly above a vanity unit or mirror, as this will throw a strong light onto your forehead and cast shadows below the eyes, nose and chin. Consider a chandelier for a high-ceilinged bathroom.

Feature lighting – to highlight design details and create atmosphere. Using LED strips in niches, under wall-mounted units or bath panels can add interest or draw the eye to a particular area.

Night lights – to come on automatically via a presence detector when someone enters at night. Try a low-level light to create a floor wash, or an LED strip under a vanity or bath panel – it’ll provide illumination while being sufficiently muted so it won’t wake others in the house.

3. Bathroom lighting safety

Bathroom lighting must adhere to strict regulations so it is safe to use in a wet environment. A suite is made up of different zones, depending on the distance to the water source, which determines the type of lighting allowed. Known as an IP (ingress protection) rating, the higher the rating, the more protected the light is.

Each zone has a rating, starting from 0, which is closest to a water source, so lighting must be immersion-proof. Outside zones are areas where no water is present. I would suggest all bathroom lights are at least IP44, even in outside zones, but always consult your electrician, and check the product descriptions before buying. Look out for lighting specifically designed to be in line with IP ratings.

Consider IP ratings

When planning a new suite, whether large or small, the space is broken into zones, each with each own level of safety regulation. Each zone has an IP rating, which determines the level of protection from moisture required and the types of light fittings allowed. All lights used in a bathroom environment, where proximity to water or steam is likely, must have an IP rating.


This is inside the bath or shower itself. Any fitting used in this zone must be rated at least IP67, which means the fitting is totally immersion proof.


This covers the area above the bath or shower to a height of 2.25m from the floor. In this zone, a minimum rating of IP45 is required but it is generally accepted that IP65 should be used to ensure safety.


This covers the area stretching 0.6m outside the perimeter of the bath and to a height of 2.25m from the floor as well as the area around the basin within a 60cm radius of any tap. In this zone an IP rating of at least IP44 is required.

Outside Zones

This is anywhere outside of zones 0,1 and 2 and where no water jet is likely to be used. There are no special IP requirements in this zone, however I always suggest that any lights used in a bathroom has an IP rating of at least IP44.

4. Energy saving bathroom lighting

While LEDs cost more, the bulbs last for up to 25 years and significantly reduce energy usage. Look out for built-in LEDs in mirrors, furniture, drawers, sanitaryware and showers, available in a range of styles and with touch-screen operation. In a contemporary bathroom, you could introduce colour-changing LED lighting or an LED rainfall showerhead.
