Nobody enjoys stepping into a cold room after a warm shower or soak in the bath. With so many heating options now available at a range of price points, we’re often asked to advise on the best option.

With the colder months fast approaching, we’ve put together answers to the most common questions to help you choose the best heating solution for your suite.


Bathroom Heating Options

Bathrooms are unique in the home in that they tend to be one of the smallest rooms, accompanied by heat, humidity and a damp atmosphere. It’s particularly important not to let your bathroom become too cold because the naturally moist environment can lead to damp, which can affect your health. Proper heating and ventilation of a bathroom can avoid such a problem, which is why getting bathroom heating right is so important - it’s not just about comfort!

When it comes to keeping your bathroom warm, you need to first consider your bathroom size and how it is used. If you have a large space, will one heater be effective for the whole space? Alternatively, if wall space is at a premium in your small suite, adding a radiator or heated towel rail may not be an option, so underfloor heating would be a key consideration.

The most popular bathroom heating options are heated towel rails and underfloor heating. Let’s take a look at each of those in more detail:

Heated Towel Rails

Heated towel rails are available in a wide range of sizes and designs. They’re a popular heating solution in modern bathrooms due to their sleek aesthetic and practicality.


Can A Towel Rail Heat A Bathroom?

The good news is yes, heated towel rails can radiate enough heat to keep your bathroom warm, whilst providing the added luxury of keeping your towels toasty.

However, you will need to consider the size of your bathroom and the amount of potential heat loss via the size of your bathroom windows. This will determine how many BTU’s (British thermal units) your bathroom requires to stay warm.

The heated towel rail size and design properties will determine its BTUs and the amount of heat it can generate. For example, coloured heated towel rails have a 30-50% better heating output than chrome towel rails.

Compared to underfloor heating, the costs for installing a heated towel rail are relatively low as they’re a lot easier to install.


Underfloor Heating

If you have limited wall space, underfloor heating is a great solution to help keep your small suite warm. Or, if space isn’t an issue but you’re after adding an extra touch of luxury, stepping out of the shower onto a warm floor can’t be beaten.

A popular option for wet rooms, underfloor heating can dry the floor after use while eliminating the dreaded step onto a cold, tiled bathroom floor.

Underfloor heating is available in two options:

Water Systems

Also known as wet systems, water underfloor heating runs hot water generated from your boiler through pipes under the floor to generate heat in your bathroom.

Wire Systems

Also known as electric systems, wire underfloor heating uses wiring under the floor to generate heat in your bathroom.


How Much Does Bathroom Underfloor Heating Cost?

Underfloor heating varies in cost depending on your bathroom size and the type of underfloor heating chosen. Initially it is often the more expensive bathroom heating option due to the cost of installation, but can be more energy efficient in the long run as it requires a lower temperature to keep your suite warm.

You’ll also need to consider the cost per square meter of an underfloor heating system , the cost of installation of both the heating system and your bathroom flooring and the potential cost of new flooring materials.

How To Heat A Bathroom Without Central Heating?

In addition to underfloor heating if you want to keep your bathroom suite warm without having to turn your entire central heating system on, you can opt for an electric plug-in bathroom heater or an electric towel warmer.

These two specific heating solutions quickly heat up your suite without having to turn on the heating for the rest of your home. However, it’s important to ensure you purchase a heater that is specifically made for a bathroom environment.
