Warm white vs cool white in the bathroom: which is best?

Colour temperature for the bathroom explained

LED colour temperature is measured in kelvins. Our bathroom mirrors and lighting range from 2,700 kelvins (warm white) to 6,500 kelvins (cool white). Many of our mirrors feature both cool and warm lighting - with just a simple press of a button, the LEDs can change from bright white task lighting to a relaxing warm white. Most of our mirrors also feature a memory function that stores your previously chosen colour for next time you switch on the mirror.

Around the home, both warm white and cool white are a great choice for downlights and spotlights, and this is best paired to suit your furniture and wall colour.

Warm Lighting

Warm white lighting has a slight yellow tint. This lighting is often used in room where you relax, such as bedrooms and lounges, as it creates a soft, calming atmosphere. Warm white light ranges from 2,500 to 4,000 kelvins and is often used in floor lamps and pendant ceiling lights.

Cool Lighting

Cool white lighting has a white output with a small tint of blue depending on the kelvin number. Ranging from 5,000 to 6,500 kelvins, it is often used in spotlights, plinth lighting and LED strip lighting. When used correctly, you can add character and dimension to your space.

In most households, you will find that the ensuite will have cool white lighting as this is more commonly used for morning routines including showering and shaving. The main bathroom is often going to have warm white lighting as this is where the family will bathe or relax during the evening and the soft light helps to set a relaxing mood.

Natural Lighting

If you fancy something in between, then try natural LED lighting. Designed to closely mimic daylight, it offers a clear and flattering illumination that’s ideal for grooming, makeup and daily routines. Typically emitting light within 4000 to 5000 kelvins, it delivers a neutral white glow that balances warmth and clarity. This combination of colour temperature and brightness helps create a natural, true-to-life appearance in any bathroom setting.

Smart Lighting Technology

Many of our illuminated mirrors feature adjustable brightness and colour temperature settings, giving you full control over your lighting experience. You can choose between fixed color options—such as cool or warm light—or opt for fully adjustable lighting, where you can slide along the kelvin scale to find your ideal temperature. Whether you're getting ready for the day or winding down in the evening, this level of customisation adds versatility and ensures the perfect lighting for any task or mood.
