You can easily replace your bathroom radiator with a towel rail and they are both installed in the same way. You may want to do this to create more storage for your towels, or you might prefer the towel rail design to complement your bathroom decor.
The quickest way to replace your bathroom radiator with a towel rail is to choose a towel rail that is the same width as your original radiator. This means that you will not have to make any pipework adjustments.
You will be able to find a new towel rail with the same heat output as your bathroom radiator. Just bear in mind that the towel rail might take up more vertical wall space than the radiator.
