How to Install LED Strips in a Bathroom

LED strips run on safe 24V DC — but the driver connects to 230V mains. All mains wiring must be carried out by a qualified electrician.

1

Check the zone

Before ordering, identify which bathroom zone each installation point sits in. IP rating requirements are set by UK wiring regulations and are not optional.

Zone Location Minimum IP
Zone 0 Inside bath or shower IP67, 12V maximum
Zone 1 Above bath/shower up to 2.25m IP65 minimum
Zone 2 Within 600mm of bath/shower IP44 min — IP65 recommended
Outside zones Rest of bathroom IP20 acceptable — IP44 recommended

Mirror lighting

Mount a surface profile (HAZE) each side of the mirror at face height. 3000K warm white gives the most flattering light for a bathroom mirror. For a halo effect, run strips around all four sides, set back slightly from the mirror edge.

3

Plinth and under-vanity

Mount a surface profile at plinth level. Use IP65 strips throughout. Warm white (2700–3000K) gives the most appealing effect at floor level.

IP65 is recommended even outside Zone 2 at floor level — cleaning water reaches further than you might expect.
4

Shower niches

IP65 is the minimum for shower niches; IP67 is strongly recommended given direct water exposure. All electrical connections must be positioned outside the wet zone. Consult your electrician before specifying any in-shower lighting.

Never position connections or driver terminals inside the shower zone — even with IP65-rated strips.
5

Connect and test

Your electrician connects the driver to the mains supply. Test the full installation — all zones — before any tiling, grouting, or surface finishing takes place.

Always test before tiling — access to connections behind finished surfaces is very difficult to restore without damage.
