What heated towel rail should I choose?

Heated Towel Rails can suffer from being an afterthought in the bathroom, but they are a great way to add style and ensure your room is perfectly cosy. Discover more about this underrated item here in our product guide:

Types of Heated Towel Rail:

Most Heated Towel Rails are either floor or wall mounted. Floor mounted Heated Towel Rails are ideal for use when there is exiting pipework that you do not want to move. As the name suggests, these ‘sit’ on the floor and connect to the heating system through the floorboards.

Wall mounted Heated Towel Rails hang on the wall using brackets, with the heating system connecting through the wall. An advantage or a wall mounted Heated Towel Rail is that it frees up floor space, which can make you bathroom feel a little bigger, or it can be positioned in unused space in a smaller bathroom or cloakroom.


A lot of people associate Heated Towel Rails with highly contemporary designs that might not work in their bathroom at home, but that is not the case at all.

There are a variety of styles available, ranging from traditional styles such as the Oakham, more modern looks like angular and space-saving Quirinius, and designs that are somewhere in between, making them highly adaptable – Portland is a great example of this.

Size and heat output:

Heated Towel Rails are one type of product where bigger doesn’t necessarily mean better. The key thing to look out for with them is the output rating, usually given in British Thermal Units (BTUs). If a Heated Towel Rail is large but has low BTUs, then it’s not going to be particularly efficient at heating your bathroom, even if it takes up most of a wall!

Make sure your Heated Towel Rail can heat your room as well as your towels by working out how many BTUs are needed to keep your bathroom nice and warm.

As a general guide, we’d suggest the following (with some heat loss allowed for): 

Cloakroom with a double glazed window - 2m L x 1.8m W x 2.4m H = 1049 BTUs

We recommend one Heated Towel Rail with an output of around 1049 BTUs; a Heated Towel Rail like the Baby Clifton floor mounted, which would work well in a smaller space.

Family bathroom with a double glazed window - 2.2m L x 2m W x 2.4m H = 1283 BTUs

We recommend one Heated Towel Rail with an output of around 1283 BTUs, such as the stylish Dolebury, which is wall mounted.

Large bathroom room with a double glazed window - 3m L x 2.4m W x 2.4m H = 2100 BTUs

We recommend one Heated Towel Rail with a BTU output of around 2100 BTUs, like the striking Cabot, available as a floor or wall mounted option.

But don’t worry, if you’re still not sure what Heated Towel Rail will best suit your space your qualified and experienced plumber or installer will be able to help guide you.
