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. This lighting is often used in bathrooms and kitchens where precise, task lighting is needed.


Cool white light ranges from 5,000 to 6,500 kelvins and is often used in spotlights, plinth lighting, and LED strip lighting. When used correctly, you can add character to the room with beautiful white LED lighting, whether this is in plinth kits along the side of your bathtub, or under-cabinet strip lighting in kitchens to highlight the worktop.

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.
