The Best Bathroom Radiator: Our Choices

Buying and rating criteria for bathroom radiators

To help you buy the best bathroom radiator, we have made this section with the most important buying and rating criteria you should consider when buying a bathroom radiator. The most important are:


The size of the bathroom radiator is a very important buying criterion that you need to consider. The size of the bathroom radiator must be large depending on the size of your bathroom. For example: If your bathroom has a size of 10 sqm (the size of a main bathroom that also contains a shower), then a heater of 920 mm × 480 mm should be enough to heat it.

For a guest bathroom, which is usually smaller than main bathrooms, then you might decide to buy a 720 mm × 480 mm heater. The room size for which a heater size is ideal is mentioned almost every time in the product specifications. It is also important to keep in mind that the price of a heater changes with its size.


You might imagine that all bathroom heaters have the same white colour, which is kind of wild. But as you could read in our reviews and recommendations section, bathroom radiators like the Design, Panel and Finesa Design bathroom radiators have different colours in which you can choose and buy something other than the stock white colour.

If you have the option to choose a colour for your bathroom radiator, you must always make sure that it blends in with the rest of your bathroom. A poor choice of colour for a bathroom radiator could draw too much attention to it in your bathroom and even ruin it. So be careful.

Heat output

The heating capacity of a bathroom radiator depends on its size. The heating capacity of the bathroom radiator is usually measured in watts. You will always find the capacity of watts that a bathroom radiator has in its title or specifications. The larger the bathroom radiator, the greater the amount of watts it can offer. On average, most bathroom radiators offer an amount of 500 watts, which are heaters with a size of 920 mm × 480 mm.

It is also important to consider the size of the bathroom you will be buying the bathroom radiator for. You would not buy a bathroom radiator with 500 watts of heating power for a 5.5 sqm bathroom. In this case, it would be better to buy one with only 300 watts of power. The higher the wattage of a bathroom radiator, the higher the energy or gas consumption.

Connection location

Heaters have different connection locations. If you want to buy or change a heater, it is very important to take a look at where the connection point of the heater is located in your bathroom.

If you buy a bathroom heater with a connection location that is not in the connection location or adapted to the connection location of your bathroom, you will have to buy a new one. Some of the different locations of the connection point in bathroom radiators are:

  • Middle/below connection
  • Bottom/top connection
  • At the sides

We could say that electric bathroom radiators are an exception to this rule because they do not have a specifically located connection point. Instead, they use a cable that is then connected to the power supply.
