Relaxing in the bathroom, taking a long soak or shower is one of the most rewarding things to do after a long day. And making that space look and feel its best only adds to the whole experience. That’s why choosing a bathroom radiator is so much fun!
Most bathroom radiators these days come in the form of stylish heated towel rails, which double as a way to dry and store towels after washing. However, there are also the more traditional radiators that can feature in the bathroom, too.
Radiators that are specifically designed for the bathroom are not just a heat source, they also add style to your room. And you can be as creative as you wish with lots of different designs, shapes and colours to choose from.
In this article, we’re going to explain the benefits of bathroom radiators and what you need to consider before buying. Plus, some of our top picks to help you on your journey.
Benefits of bathroom radiators
Choosing to install a bathroom radiator or heated towel rail is a fantastic addition to your space. Not only do they help to keep your bathroom warm, dry and mould-free, they are also a great way to maximise your aesthetic.
Let’s take a look at some of the top benefits.
- Bathroom radiators can save on space making them ideal for smaller bathrooms, cloakrooms or ensuites, as well as larger rooms too.
- You can benefit from a year round heat source in your bathroom to make it super cosy.
- The warmer the surfaces are in your bathroom, the less condensation will settle, meaning less chance of damp.
- Having a bathroom radiator or towel rail will help to keep your room at an optimal temperature.
- Heated towel rails are designed to keep your towels fresh and warm, whilst providing heat across the room - perfect for when you just jump out of the shower!
- With so many great styles to choose from, you can match your bathroom styling or use the radiator to add wow factor as a statement piece.
Things to Consider when Choosing a Bathroom Radiator
When deciding on a radiator for your bathroom, what do you need to consider? Ask yourself at least these 3 questions before you take the plunge.
1. What is my BTU?
BTU stands for British Thermal Unit and is a measure of how much heat a radiator can output to increase the temperature of a room. Your BTU rating takes into consideration factors like floor space, room height and other specifics.
But no one expects you to know this off the top of your head. That’s why we’ve made it really easy to work out what your BTU rating is for any room, including your bathroom. Before you purchase any radiator, make sure to use our BTU calculator to find out which rating you need.
Each radiator on our site should have its heat output and BTU rating compatibility stated within the product descriptions. If you are unsure, just jump on a chat with one of the team and they’ll be happy to help.
2. Is a radiator or heated towel rail more suited for my bathroom?
These days, heated towel rails are a much more popular choice for those who are looking to add style to their bathroom. But how do they compare with traditional radiators?
If you have a small to medium sized space then a heated towel rail is likely to provide enough heat to keep the room warm. The beauty of this is that you have a much wider choice when it comes to design. And, with rising energy bills, a heated towel rail can be a much more economical choice.
For those who have a larger space, the right size radiator is probably going to be more efficient in heating your room, but you may find there’s still plenty of room to incorporate a heated towel rail too - so you have the best of both worlds!
If you do decide to go for a heated towel rail, then it’s important to check your BTU against your chosen product to make sure there is enough to heat your room.

3. Am I going to need building work?
If you currently do not have any heat source in your bathroom, then you need to consider whether installing a radiator or towel rail is going to be a bigger job than you imagined. If you decide to have a radiator plumbed into the mains, where are you likely to get access to the pipes and does that suit your bathroom layout and where you envisaged the heat source to go?
If you already have a radiator in place but are looking to upgrade or switch to a heated towel rail, then consider if there is enough space for you to do this?
We’ll come on to the different types of bathroom radiator next, but if you are not a confident DIYer or don’t have plumbing experience, then we would always suggest asking the advice of a professional before attempting to install on your own.
Types of bathroom radiators
OK, so lots to consider so far. But probably one of the biggest decisions of all, is what heating type your new bathroom radiator will use. So, let’s explore what heating type your radiator can be in the bathroom.
Electric
These radiators are wired into the mains and are operated by a switch just like you would switch on a light. They are easy to install and are ideal if you have a smaller space or do not have a gas supply or central heating system.
One of the great benefits of an electric radiator in the bathroom is that you have more control over the temperature of the room - and the heating can be isolated to this radiator if you are just wanting to dry towels, for example. Plus, maintenance of an electric radiator is fuss-free - there’s no need to bleed and you don’t need any additional pipework fitted in order to use.
Here’s some of the more popular electric radiators.
Central heating
Another option is to choose to use a central heating radiator. This will be plumbed into the mains and work just like any other radiator.
This is the most common radiator in the home, but in the bathroom you do find more people are now opting for one of the other types as it gives them greater control and more efficiency.
We still have a fantastic choice of central heating radiators, just like these which are ideal for the bathroom.
Dual Fuel
Finally, the dual fuel radiator, which offers greater flexibility on how you can use it. The radiator functions both with central heating and electricity, so you can decide which is the most efficient way to use it at any given time.
For example, in the summer you may wish to switch to electricity so that you don’t waste hot water by switching on all the radiators in your home, helping to save you money on your energy bills.
Here’s a look at some of our most popular dual fuel radiators for the bathroom.
