Heating a bathroom efficiently and effectively is a unique challenge compared to the rest of your house. The combination of moisture, limited space and changing temperatures means traditional heating systems aren’t always quite as effective as you’d like them to be.
Most conventional household heating works by warming the air, but this isn’t necessarily the most efficient and plenty of heat can be wasted. Traditional methods can also take a little while to warm up, which can leave bathrooms feeling cold and uninviting in the mornings.
Infrared heating offers a different solution. They work by warming objects and people up directly rather than heating the air. This targeted approach makes infrared heating an energy-efficient and effective way to keep bathrooms warm.
This guide will take a look at why infrared heating is an excellent choice for bathrooms, the types to choose from and why you should seriously consider installing it.
Best types of infrared heating for your bathroom
Infrared heating works differently from traditional bathroom heaters by directly warming objects and surfaces rather than heating the air. This makes it particularly effective in bathrooms, where steam and moisture can cause issues like condensation and mould growth.
Infrared panels work in a bathroom by emitting electromagnetic waves that are absorbed by walls, floors and fixtures, keeping them warm and reducing dampness. Unlike convection heaters, which circulate humid air, infrared panels prevent moisture build-up by keeping surfaces at a more consistent temperature. This helps to create a more comfortable and healthier bathroom environment.
There are various types of infrared heaters available for bathrooms:
- Ceiling-mounted panels – An excellent way to maximise space is to position an infrared panel on the ceiling. This provides uniform heat distribution and reduces the risk of contact with water. They are ideal for smaller bathrooms with limited wall space, but work just as well in larger bathrooms too.
- Wall-mounted panel – A popular option, wall-mounted infrared panels can be placed strategically to provide effective heating. Available in various finishes, including glass and ceramic, they can complement modern bathroom designs very nicely.
- Infrared mirror heaters – Infrared mirror panels are rather ingenuous and serve a double function: they work as both your mirror and heating. Because the mirror is heated, steam doesn’t form on the surface meaning you get a clear look at yourself every time!
What are the benefits of installing infrared heating in a bathroom?
Infrared heating provides a range of advantages for bathroom heating. These benefits can make it a superior choice for a lot of homeowners who want a change to something a little smarter and more suited to a bathroom environment.
- Energy efficiency and cost savings – Infrared heating converts almost 100% of the electricity it uses into heat. Since it directly warms bathroom surfaces, such as tiles and walls, rather than the surrounding air, it minimises energy waste and provides cost-effective heating. Compared to electric fan heaters or radiators, infrared panels require less power whilst delivering great, sun-like warmth, making them ideal for bathrooms where quick, efficient heating is needed.
- Quick heat-up time – Traditional radiators and underfloor heating systems can take time to warm up, leaving you with a chilly bathroom on cold mornings. Infrared panels however, provide almost instant heat as soon as they’re switched on. This means your bathroom will always be warm and toasty when needed – a massive bonus on those cold days when you get out of the shower.
- Health benefits – Infrared heating reduces moisture build-up, which helps prevent mold and mildew growth, both common issues in bathrooms. By keeping walls, ceilings and tiles drier, infrared heating promotes better air quality and reduces the risk of damp-related health issues.
- Space-saving – Infrared panels can be mounted on walls or ceilings, making them perfect for compact bathrooms where space is at a premium. Infrared mirror heaters are an excellent choice as they combine the functionality of a non-steam mirror with efficient heating.
- Moisture resistance and safety – Bathrooms are humid environments, so heating solutions must be resistant to moisture. Many infrared panels are IP-rated for bathroom use, meaning they are designed to withstand splashes and high humidity.
What are the upfront costs and on-going running costs?
The initial cost of infrared panels for a bathroom varies based on size, power output and design.
Prices tend to range from £150 to £500 per panel, with smaller models suited for compact bathrooms and larger, high-wattage panels providing more comprehensive heating.
Whilst this may be more expensive upfront compared to traditional electric heaters or towel rails, the long-term energy efficiency and lower running costs can help offset the initial expense.
A 500W infrared panel usually costs around 12.5p per hour to run – this is based on an electricity rate of 25p per kWh. Given that bathroom heating is often used in short bursts, such as 30-60 minutes in the morning and evening, the daily running cost can be as little as 12.5p-25p per day or approximately £3.75-£7.50 per month for regular use. We’d say that is excellent value.
For comparison an standard electric towel rail may use a similar amount of energy and cost roughly the same to run. However, because infrared heating directly warms surfaces and people, less energy is lost which makes infrared a more efficient heating option.

How to maximise efficiency and reduce costs
Infrared panels aren’t necessarily part of a central heating system. Instead they can be individually controlled and programmed in a smart, efficient way so that they’re only used when needed through the use of smart thermostats and timers.
Most infrared panels can be paired with mobile apps, allowing you to schedule heating times easily and avoid unnecessary energy use.
Here are some of the smart features you can make use of:
- Thermostat integration – Many infrared panels come with built-in thermostats or can be connected to an external thermostat for precise temperature control.
- Timer functions – Pre-set schedules allow users to turn heating on and off automatically.
- Mobile app control – Infrared heating systems that integrate with apps like Smart Life and Tuya provide remote control via smartphones.
- Voice control – Many systems work with Alexa and Google Assistant, allowing homeowners to adjust heating hands-free.
How to install infrared panels in a bathroom?
Installing infrared heating panels in a bathroom requires careful placement. Ceiling-mounted panels provide excellent coverage and keep heating elements safely out of reach, whilst wall-mounted options work well in larger bathrooms where space allows for strategic positioning.
Professional installation is recommended for most infrared bathroom heaters This is because they often need hardwiring into the electrical system. For bathroom use, make sure you get an IR panel with an IPX4 rating or higher so that it’s resistant to splashes and humidity.
Once installed correctly, there’s very minimal maintenance. The panels have no moving parts and require only an occasional wipe-down to keep them clean and free from dust. With this, you can expect an IR panel to last 10-15 years no problem.
How to choose the right infrared heating for your bathroom?
When choosing an infrared heating system for your bathroom, it’s essential to consider IP rating, power output and design suitability. Make sure the panel has an IPX4 rating or higher to guarantee moisture resistance. Also, check for thermostat compatibility and smart controls for improved energy management.
The size of your infrared panel should match the dimensions of your bathroom:
- For smaller bathrooms (up to 3m²), a 300W-400W panel is usually enough
- Medium-sized bathrooms (4-6m²) may require a 500W-700W model
- Larger bathrooms (7m² and above) may benefit from multiple panels or a 900W+ system.
There are a number of well-regarded brands that manufacture high-quality infrared heating panels suitable for bathrooms. Herschel, for example, offers mirror infrared panels and ceiling-mounted options specifically designed for wet environments. Other brands provide stylish black or white glass finishes to fit in nicely with modern bathrooms.
