Long gone are the days when bathroom radiators were considered a luxury item and owning them was a dream for many. Now bathroom radiators are deemed essential for bathroom heating because who doesn’t want to step out to a warm and cozy bathroom after a long and soothing hot water shower.

However, buying a perfect bathroom radiator among all the available options can be a daunting task. But don’t worry!! Here we have listed five essential things that you must consider before buying a bathroom radiator.

1.    What Size Do You Need?

First things first, you must determine what size of bathroom radiator is suitable for your bathroom. Bathroom radiators come in all sorts of sizes ranging from 700x400mm to 1800x600mm.

So, while choosing the right size, you must consider that a too big radiator would increase your heating bill and wouldn’t look as well, and too small a radiator would be of no use if it fails to heat the bathroom.

2.    What Storage Capacity Are You Looking For?

Bathroom radiators are multifunctional devices. Apart from heating your bathroom, they also serve as towel dryers or heaters.

So, while you have assessed the size of your bathroom and what size of bathroom radiator is best for you, you must determine how many people use the bathroom? or how many towels would be hanged on the towel rail at a time?

3.    How Much Heat Do You Need?

Now you should determine how much energy would be required to heat your bathroom. This is essential because it would help you buy the appropriate electric bathroom wall heater or bathroom radiator for your bathroom.

Heat output or BTU (British Thermal Unit) can be easily calculated using an online tool. All you need to do is input your room’s dimension, type of windows in the room, sun exposure time, and climatic conditions, and you will have your BTU with you.

4.    Which Heating System Do You Want?

Well, there are two types of radiators. First is the fully integrated bathroom radiator. It works with your underfloor heating system, and installing them is tricky. You need to figure out where your pipes are located; what type of walls do you have? And would you need new valves or the old ones would work?

With electric radiators, an underfloor heating system does not matter. They are independent devices; you can turn them on and off any time, and they are easy to install.

Another option is dual fuel bathroom radiators. You can use these radiators with an underfloor heating system as well as independently as electric radiators.


Lastly, the most critical step is to decide which material is suitable for your bathroom and budget. Affordable options are made of mild steel, which is not ideal for wet and humid rooms.

Stainless steel, chrome, and aluminum are safer but expensive options. However, aluminum is the most popular because of its high heat output and space-saving feature for smaller bathrooms.
