A bathroom heater, in the form of an electric designer panel or downflow heater, is the perfect way to give your bathroom an instant burst of heat. Whether your bathroom or en-suite is small or large, it’s the best way to keep it nice and cosy without having to install a radiator.

Although there are many electric heaters on the market, not all of them are bathroom-safe. Therefore, for complete peace of mind, all of our recommendations have been tested for bathroom use and have a waterproof rating of IP20 or greater.

To assist you in selecting a bathroom heater, our handpicked selection lists top-performing models, chosen based on our first-hand experience installing and using a range of bathroom-safe heaters. Our testing and up-to-date research further ensure the quality of our recommendations.

How The DIY Works Team Tests & Rates Bathroom Heaters

As we own a number of properties (Airbnb’s and rental properties), we’ve installed several electric heaters over the years to take the chill away in the bathrooms. From the latest designer panel heaters to the downflow alternatives, we’ve installed multiple types and they’ve certainly made a big difference during the winter.

To keep up our commitment to reviewing and testing the latest bathroom heaters (for this article), we are continually testing the latest offerings from top brands in the UK. This means that when we notice that a brand has released a new and improved heater, we will attempt to upgrade our current bathroom heaters for testing (where applicable).

During our ongoing testing, we analyse the heater’s performance, usability, ease of installation, heat settings and timers. Below are some photos of both a panel and downflow heater that we recently put to the test.

As well as our testing and experience installing multiple bathroom heaters, we also based our recommendations on the latest research and several factors. Some of the factors that we took into consideration included the heater’s build quality, performance, ease of operation and installation, heat settings, additional functionality, IP rating, power options available, timers, design, warranty and value for money.

1. Best Electric: Purus Eco Bathroom Heater

(How We Review →)

Although there are many electric heaters on the market, there are very few that are dedicated for use in the bathroom. However, the Purus Eco is a bathroom safe heater that’s IP24 rated and features plenty of intuitive functions.

According to the brand, their bathroom heater has a simple “plug in and go installation” and it also has a 1.45-metre power cable for reaching most sockets.

  • Available as a 600, 1200, 1600 electric heaters
  • Bathroom safe with a IP24 waterproof rating
  • Choice of three heating modes
  • 24/7 digital timer that’s easily programmable
  • Easy to install and setup
  • Backed by a 2 year guarantee
  • From our testing, we found that programming the schedules wasn't as straightforward when compared to the alternatives

To conclude, the Purus Bathroom Heater is an excellent all-round option that’s completely bathroom safe and available in a range of heat outputs to best suit your requirements. Compared to similar heaters designed for a bathroom, it also offers great value for the money and a two-year warranty for peace of mind.

2. Best All Rounder: FUTURA Eco Electric Bathroom Heater

(How We Review →)

The Futura Eco is another bathroom heater that’s available in a variety of heat outputs and has an IP24 rating. However, the design differs as the display isn’t facing outwards and it’s slightly smaller in size.

In terms of the available heat outputs, the brand offers this heater as a 600, 1000, 1200, 1500, 1800 or 2000W model.

  • Multiple heat outputs available
  • Lightweight at just 5.8 KG
  • Wall mounted or free standing design
  • Automatic functionality for maximum efficiency
  • Relatively expensive when compared to other electric bathroom heaters

Overall, the Futura Eco ticks all the boxes and combines performance with value for money. It’s also available in a great selection of heat outputs to best suit your requirements and room size.

3. Best Smart: Wärme Designer Electric Heater

(How We Review →)

Another premium electric bathroom heater that’s worth considering is by the Warme brand. It’s a stylish, splashproof and completely maintenance-free heater that’ll make the perfect addition to any modern bathroom.

It’s the brand’s new and improved model that’s known as the Generation X and it’s now WiFi enabled. The benefit of this is that you can now connect the heater to the brand’s dedicated application for remote control access and scheduling.

  • Ultra slim design (8 cm)
  • 2,000 watt heat output
  • IP22 waterproof rated
  • Programmable thermostat
  • WiFi enabled for remote control access
  • Compatible with the Alexa
  • Versatile design that can be installed around the home
  • Limited options to choose from in terms of power and sizes

Although expensive, the Wärme Heater is the ultimate gadget for heating your bathroom and it’s packed full of functionality. The dedicated WiFi application is a great bonus that’s convenient and also really easy to use too. As well as testing this electric heater in bathrooms, we’ve also used it to heat conservatories, which it also does brilliantly.

4. Best Fan: Dimplex FX20VE Downflow Bathroom Heater

(How We Review →)

The Dimplex brand has been producing heaters for many years and most old-school electricians will favour their products. The FX20VE model in particular is the brand’s bathroom downflow heater that can be wall mounted and features a simple pull cord for turning it on and off at your convenience.

In terms of the installation, to install this bathroom heater, it requires no plug and it can be fixed to a wall with 3 screws.

  • Simple pull cord operation
  • Runs from a 30 minute timer
  • Backed by a two year guarantee
  • Easy to install with three screws and an earth wire
  • Power output of 2,000W
  • Quiet operation
  • Most expensive bathroom fan heater within our roundup

If there is no room for any of the designer bathroom heaters recommended above, the Dimplex FX20VE downflow heater is the perfect solution. Its wall-mounted design pushes heated air down into the bathroom for instant heat and during testing, the additional power from this model heated the bathroom very quickly.

5. Best Value Fan: Winterwarm Bathroom Downflow Heater

(How We Review →)

Another downflow bathroom heater that’s perfect for small bathrooms is the Winterwarm WWDF20E. It’s very similar in design to the Dimplex alternative above and features a pull cord for operation as well as two heat settings.

  • 2,000 watt heat output
  • Pull cord operation that provides instant heat
  • Easy three wire installation
  • Choice of two heat settings
  • Flame resistant construction
  • IP22 rated
  • During testing, we felt that the build quality could be improved (plastic quality wasn't as solid as the Dimplex alternative above)

To conclude, the Winterwarm WWDF20E is another great option for providing instant heat to your bathroom at an affordable price. It’s completely bathroom safe with an IP22 rating and is easy to install and use daily during the winter.


Unlike bathroom towel radiators, an electric heater (in the form of a designer or downflow heater) requires no plumbing and it can be installed in a matter of minutes. Whether you opt for one of the designer or downflow recommendations above, both are bathroom safe and provide much-needed instant heat during the cold winter months.
