Best Bathroom Heater Reviews – Top 7 Picks

1. Wärme 2000W (Editor’s Choice)


Thanks to its high performance and sleek, modern design, the Wärme Electric Heater is our favourite wall mounted bathroom heater.

Its streamlined form takes up minimal space making it a great choice if your bathroom is on the small side, while its 2000W output is recommended for rooms as large as 22 square metres. Most importantly, it is waterproof and IP22 compliant.

This bathroom wall heater comes complete with a mounting kit, so you’ll be able to fix it to your wall within minutes. Unfortunately, the instructions provided are a little complicated and programming it is rather complex until you get the hang of it.

It has a convenient programmable weekly cycle, but equally, you can just use the instant heat mode and benefit from its speedy heating performance. The inbuilt thermostat works very well. However, you may want to set the temperature a little higher than you need as it requires a five-degree drop in temperature for the heater to come back on. It also comes with a child lock, making this a great choice for families with small children.



  • 2000W output suitable for rooms up to 22 square metres
  • Stylish, modern design
  • Meets IP22 – fully waterproof casing
  • Instant heat mode or programmable weekly cycle
  • Child lock for added safety


  • Instructions are difficult to understand

This stylish, curved-corner bathroom heater by Futura will look great in any bathroom. It has a modern circular control panel complete with thermostat, 24/7 programming and open window detection.

The electric Futura panel intelligent heater also comes with a child lock function, making it a safe choice if you have inquisitive children. There’s a choice of three heating modes: comfort, economy or frost-free. However, this electric heater for bathroom use comes with instructions that are rather difficult to understand. It’s also fairly complicated to program, although you could opt to use it on a simple start and stop basis.

While mounting this heater with its included wall brackets is fairly simple, there’s no template included. If DIY isn’t your thing, be prepared to spend a little while to get the holes correctly lined up.

  • IP24 rated
  • Three heating modes: comfort, economy and frost-free

The Purus Intelligent heater also features a 24/7 timer, so you can set it to come on at a specific date and time – although programming is quite tricky and takes a while. Another thing to note is that this bathroom heater is turned on and off via a touch button on the panel, so smart plugs won’t be compatible.

It comes complete with a handy thermostat setting to help you keep a constant comfortable temperature starting from the first splash of water until you dry off with your towel. Furthermore, the useful child lock function makes it a great choice if you have children in the home.

It is IP24 rated and Lot 20 compliant. Therefore, it safe to use in the bathroom, better for the environment and cheaper for you to run.

This heater can be used either free-standing or wall-mounted. However, due to the surprisingly bulky nature of its feet that comes with castor wheels, we would recommend wall mounting when possible.

The clear LED display is easy to read, although the programming instructions are difficult to understand. So, if you need to program your heater throughout the week, you’ll be better off looking at another of our recommendations. Otherwise, you can easily use this model with the on/off switch and its internal thermostat.

Like a lot of heaters, the thermostat could be more accurate. However, it is easy to use and this does not really detract from its performance.

It has a timer that can be used to set it to run for a certain length of time. But if you’re looking for a bathroom heater that can be set to come on at different times on different days, then you would need to purchase a separate timer for this added functionality.

If you open your window after you shower to air the room and prevent the build-up of humidity, you won’t have to worry about forgetting to turn off your heater.

Thanks to its fan that circulates warm air around your bathroom, you won’t have to wait to experience a warm sensation before taking your shower.

  • 600W portable ceramic fan heater for targeted heat
  • Over-heat and tip-over protection
  • Heats up in three seconds
  • Two speed, oscillating fan


  • Does not warm the whole room effectively
  • Not particularly durable

What Are the Different Types of Bathroom Heaters?

There are several different types of bathroom heater available. To help you to make the right choice, we’ve detailed some of the main types below along with their advantages.

1. Convection Bathroom Heaters


Convection electric bathroom heaters are one of the most common types that you will come across. As their name suggests, these heater work via convection. They warm the air surrounding them, which rises once warmed. This continues with the warmer air rising and then cooling, followed by more rising and cooling and so on.

The advantages of convection heaters are that, unlike fan heaters, they don’t have moving parts that can break, and they don’t require any regular maintenance. They are good at heating entire rooms over long periods of time, and once your convection bathroom heater is installed, you can simply forget about it. On the downside, they can take a while to warm up a room and you don’t get the same targeted warmth as you do with a fan heater.

2. Fan Bathroom Heaters

Fan heaters warm the air and then propel it forward, for a more intense, targeted hot air flow. They are useful for immediate heat – rather than waiting for a whole room to heat up. You can immediately bask in the warmth created by a fan heater.

However, while they are good at heating up small rooms, they are less effective in larger rooms. As with any fan, you’ll have to regularly check your bathroom fan heater for a build-up of dust or other particles that could block the filter and cause malfunction. Based on some bathroom heater reviews, most say that fan heaters tend to be pretty noisy. However, if you regularly use your electric shower rather than bathe, the noise is not likely to be noticeable.

3. Infrared Bathroom Heaters


Infrared heaters use infrared radiation to warm objects and people, rather than just the air as convection and fan heaters do.

This makes infrared heaters more efficient than convection heaters and more economical to run. They don’t create draughts and are completely silent, making them a good choice for many households.

One particular advantage of using infrared bathroom heaters is that the infrared rays will also warm the walls, rather than just the air. This means it can help to keep mould at bay. These can also be used as ceiling heaters for bathrooms in the UK if your area is limited and would like to save space.

Features to Consider When Choosing a Bathroom Heater

In this section, we look at some of the most important features to consider when picking the best bathroom heater for you.

1. Heat Output

You’ll need to make sure that your bathroom heater has a sufficient heat output for the size of your bathroom. If you have a large bathroom then you’ll need one with a larger wattage than someone with a smaller bathroom.

Therefore, make sure you check the recommended maximum room size before buying. If you use a heater that’s not powerful enough, it won’t be able to effectively warm your bathroom, resulting in slight warming that won’t make enough of a difference in the winter months.

2. Safety Standards

When you’re looking for a new bathroom heater, make sure you’re considering models which comply with the latest safety standards for use in bathrooms.

Heaters for bathrooms need to comply with certain ratings which depend on how waterproof or splash proof they are. This, in turn, dictates how close to a water source they may be installed.

Remember, if you are wall mounting your heater inside your bathroom, it must be installed by a professional. This is to guarantee your safety.

3. Portable or Wall Mounted

Some bathroom heaters come with both feet and brackets, giving you a choice while others are just one or the other.

A wall mounted bathroom heater saves space and makes for a tidier, less cluttered bathroom. Looks aside, it can also be more practical to have your bathroom heater wall mounted, avoiding trailing electrical cables and freeing up vital space in very small bathrooms.

However, using a portable bathroom heater can be preferable if you intend on using the heater as a complementary heat source for other rooms in your home. If you’re having some difficulty to get one fitted, then a portable one would be better.

4. Energy Efficiency

Not only are they important for ecological reasons, but an efficient bathroom heater will save you money. Make sure that your bathroom heater complies with all new efficiency standards to save on your electric bills.

Another thermostat function is the auto shut off. It allows you to save money by cutting off your bathroom heater when the room reaches the desired temperature. Open window detectors work in a similar way and are particularly useful if you regularly open your bathroom window to reduce humidity build up.

If you’re prone to forgetting to switch heaters off, a timer function is also useful to help you save electricity cost and money.
