The Ingress Protection (IP) rating system, defined under standard BS EN 60529, classifies the degree of protection an electrical enclosure provides against solid objects and moisture. For illuminated bathroom mirrors, the IP rating determines where a given fixture may be legally and safely installed. Selecting the correct rating is not optional — it is a building regulation requirement that governs mirror placement in every hotel, residential and commercial washroom project.
Understanding the two-digit IP code
An IP rating is expressed as two digits — for example, IP44 or IP65. The first digit indicates protection against solid ingress (dust and foreign bodies), while the second digit indicates protection against moisture. Among illuminated mirrors, the two most common ratings supplied to the trade are IP44 and IP65, with each one mapping to a specific bathroom zone.
IP44 mirrors — general bathroom use
Rated IP44, a mirror is protected against solid objects larger than 1mm and against water splashing from any direction. This rating is suitable for the majority of hotel and residential vanity installations sited beyond the shower and bath zones. Where a mirror sits more than 600mm horizontally from the edge of a bath or shower, an IP44-rated mirror satisfies the requirements of BS 7671 (the IET Wiring Regulations). It is the standard specification for ensuite, guest-bathroom and powder-room mirror placements across hospitality projects.
IP65 mirrors — direct wet-area specification
Rated IP65, a mirror is fully dust-tight and protected against low-pressure water jets from any direction. This rating is required for mirrors installed inside shower enclosures, steam rooms or any location directly exposed to water spray. Spa facilities, wellness centres and high-end hotel suites with rainfall showers frequently specify IP65-rated mirrors to meet both safety and durability expectations over the lifetime of the installation.
Where each rating applies — bathroom zones
UK bathroom zones define the minimum IP rating required at each mounting position. The table below maps each zone to the minimum acceptable rating for an illuminated mirror.
Specifying the correct rating
When requesting a quote, specify the exact mounting location of each mirror — wall, distance from the nearest bath or shower, and whether the room includes a steam or wet-room function. Lumos manufactures both IP44 and IP65-rated illuminated mirrors to bespoke dimensions, with factory-fitted demister pads, tuneable-white LED lighting and capacitive touch controls. Every unit is powered up, inspected and logged before despatch to guarantee on-site compliance with no commissioning surprises.
Certified compliance
CE, UKCA and RoHS documentation included with every order.
Sealed LED systems
LED strips are encapsulated to preserve the stated IP rating across the mirror face.
Zone-accurate rating
Confirm the mounting zone for each unit — an incorrect rating fails compliance.
