Infrared Heating for Bathrooms: A Practical Buyer’s Guide (UK) + What to Buy
Infrared Heating for Bathrooms: A Practical Buyer’s Guide (UK) + What to Buy
Bathrooms can be some of the hardest rooms to heat: lots of hard surfaces, frequent ventilation, and sudden bursts of humidity. Infrared bathroom heaters solve this differently to radiators and fan heaters — they warm people and surfaces directly, helping comfort arrive faster and discouraging condensation from settling on cold walls and mirrors.

Why Infrared Works So Well in Bathrooms
Traditional convection heating warms the air first — but bathrooms often lose that warmth quickly through extraction and drafts. Infrared works the other way around: it warms surfaces (tiles, walls, towels) and you, so the room feels comfortable even when the air is changing.
- Fast comfort: you feel warmth quickly, typically within minutes.
- Lower condensation risk: warmed surfaces are less likely to attract moisture.
- Quiet + clean heat: no fans, no air movement, less dust circulation.
- Space-saving: ceiling or wall mounting keeps floors clear.

Bathroom Safety: Can You Install Infrared Heaters in Bathrooms?
Yes — as long as the heater is suitable for bathroom zones and installed to UK electrical regulations. The key thing to look for is the IP rating, which tells you how protected the heater is against moisture and splashes.
What IP Rating Do I Need?
- IP44: commonly suitable for bathroom zones where splash protection is required.
- IP54: adds improved protection against water splashes + dust ingress.
- IP65: higher protection, typically used where exposure is more direct (product/zone dependent).
Always follow the manufacturer’s zone guidance and your electrician’s advice — and if you want help selecting the right heater for your bathroom layout, you can reach us here: Contact Eco Friendly Heating.
Can I Put a Heater Directly in the Shower?
Generally, no. Most bathroom heaters must be positioned outside the most exposed wet areas and installed with correct clearances. As a simple rule of thumb, maintain safe separation from direct water spray areas and always follow zone rules and product instructions.
Do Infrared Bathroom Heaters Help With Damp, Condensation & Mould?
They can help — not by “dehumidifying” the room like a dedicated appliance, but by warming surfaces so condensation is less likely to settle. That can reduce the conditions that encourage mould, especially when combined with good ventilation and sensible heating schedules.
If you’re aiming to reduce wasted heat and run bathrooms efficiently, our Carbon Neutral Heating Guide is packed with practical tips on zoning and heating only what you use.
Do Far Infrared Panels Glow?
No — the type typically used for home heating does not emit visible light. It’s silent, steady warmth without the orange glow you’d see from halogen or quartz-style heaters.
How Fast Do They Heat Up?
You’ll usually feel the effect quickly because infrared warms you and nearby surfaces directly. Full room comfort depends on insulation, extractor use, and heater sizing.
Choosing the Right Type of Infrared Bathroom Heater
1) Mirror Infrared Heaters
Perfect when wall space is tight. A mirror heater gives you two functions in one — bathroom mirror + comfortable radiant heat. Many customers choose these for en-suites and smaller bathrooms.

2) Towel Rail / Towel Heaters (Infrared)
If you want warm towels and a warm bathroom, towel-style infrared heaters are a brilliant option. They deliver radiant comfort and can help keep the room’s “cold corners” feeling less clammy.
Where to add products:
3) Ceiling-Mounted Infrared Panels
Ceiling mounting is often the cleanest look and keeps the heater safely out of reach — great for family bathrooms and compact spaces. It can also improve coverage because heat is delivered down into the room.

Controls & Running Costs: How to Keep Bathroom Heating Efficient
Bathroom heating is a classic “short burst” zone: you want warmth when you’re in there — and minimal energy use when you’re not. The easiest win is pairing infrared with appropriate controls so it runs on a schedule or only when needed.

Quick Sizing Guide: What Wattage Do I Need for a Bathroom?
As a very general guide, many bathrooms fall around 75–100W per m² depending on insulation, extraction, external walls, and ceiling height. This is only a starting point — bathrooms vary a lot.

Frequently Asked Questions
Can I safely install an infrared heater in a bathroom?
Yes — provided it is correctly IP-rated for bathroom use and installed in line with UK electrical regulations and bathroom zone requirements.
What IP rating do I need for a bathroom?
Common bathroom-friendly products are often IP44 or higher, but the correct rating depends on where it will be installed (bathroom zones) and the product’s guidance.
Are infrared bathroom heaters safe for children and pets?
Yes, when installed correctly. Ceiling mounting keeps heaters out of reach, and wall-mounted heaters should be positioned sensibly because surfaces can become warm during operation.
Do infrared heaters help with mould and damp?
They can help by warming surfaces so condensation is less likely to settle. For best results, combine with good ventilation and heating schedules.
Do far infrared panels glow?
No. Far infrared used for home heating does not emit visible light — you get silent warmth without an orange glow.
How fast do infrared bathroom heaters heat up?
You’ll usually feel radiant warmth quickly because infrared heats people and surfaces directly. Total room comfort depends on room size, insulation and heater output.
Do infrared heaters work as anti-fog mirrors?
Many infrared mirror heaters stay clearer during use because the mirror surface is warmed. For standard mirrors, you can also use a dedicated demister pad.
Can I heat the whole bathroom with infrared?
Yes, when heaters are sized correctly for the room and controlled properly. Larger or poorly insulated bathrooms may need a higher wattage option or more than one heater.
Where is the best place to mount an infrared heater in a bathroom?
Often on the ceiling or high on a wall for good coverage and to keep floor space clear. Always follow zone guidance and the manufacturer’s recommended placement.
Do I need an electrician to install it?
For bathrooms, hard-wired installation is typically recommended and should be carried out by a qualified electrician.
Are infrared bathroom heaters expensive to run?
They can be very efficient because they convert electricity into usable heat and work well with zoned, timed heating. Running costs depend on your tariff, heater wattage and how long it runs.
Do infrared heaters need servicing?
No — there are no moving parts. Occasional gentle cleaning is usually all that’s required.
How long do infrared panels last?
Quality infrared panels are designed for long lifespans — often many years — especially when installed and controlled correctly.
