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.
