Bathroom Heating Options for Winter and Beyond
With various bathroom heating options available today, choosing the right solution provides a warm, moisture-controlled environment while meeting budget and style preferences.
A warm bathroom can make all the difference during the colder months, turning an otherwise chilly morning routine into a much more comfortable experience.
Selecting bathroom heating options depends on several factors, including the size of the space, layout, budget, and desired heat output. Smaller bathrooms may require minimal heating, whereas larger rooms could benefit from multiple heat sources to ensure even warmth.
Positioning is also crucial; installing heaters near splash zones or too close to water sources can pose safety risks, so it’s essential to choose bathroom-specific solutions and ensure professional installation. A bathroom refurbishment or remodelling can potentially add between 4-5% onto the value of your home, according to The Property Centre.
Bathrooms have unique heating needs due to their high humidity levels, which increase after each shower or bath. Unlike other rooms, bathrooms are prone to dampness and mould growth if not adequately heated, especially in winter.
Proper heating can help prevent these issues by maintaining a consistent warmth, which reduces moisture buildup and keeps damp at bay.
Aside from functional reasons, bathroom heating can also create a more pleasant environment by adding warmth exactly where and when you need it. Whether your bathroom is large or compact, choosing the right heating solution can make a noticeable difference in comfort and maintenance.
#1 Radiators
Radiators remain a popular choice for bathroom heating, offering effective and reliable warmth.
They come in a variety of designs, from classic column styles to sleek, modern panels that can complement any decor.
Traditional column radiators
- Classic column radiators are large and very efficient, and will therefore supply substantial amounts of heat to large bathrooms.
- Modern versions come in a range of colours for a unique look, and these radiators are often available in neutral shades like white or anthracite.
- They occupy more wall space but offer a higher heat capacity making them suitable for larger rooms.
Flat panel radiators
- Modern flat panel radiators, typically fitted vertically, are excellent space savers due to their flat design.
- They come in various sizes to fit different wall dimensions and give off a high level of heat without looking out of place.
- For those that like the multi-functional options, some models feature a mirror as well, so you do not need a separate one hanging on the wall.

#2 Heated towel rails
- Heated towel rails double as bathroom heating and drying solutions, warming and drying towels at the same time.
- Wall mounted and slim, most heated towel rails are ideal for smaller bathrooms, or for providing additional warmth.
- Available with chrome or matte black finishes, modern heated towel rails are great in different bathroom styles and a heated towel rail may be enough to warm you in a smaller bathroom.
- However, in a larger space an additional heat source can help keep the temperature even across the room.

#3 Electric bathroom heaters
- Electric bathroom heaters are easy to use, and the instant heat and on/off switch makes it easy for people who want heat quickly rather than waiting for the central heating system to warm up.
- From compact fan heaters to more substantial electric radiators and heated towel rails, there are electric heaters available in a variety of styles.
- Additionally, these heaters are independent of the central heating system, and in some situations they can be a highly efficient choice. However, if you use these heaters often electricity costs will rise.

#4 Underfloor heating
Adding underfloor heating to your bathroom floor heats it, brings an added level of comfort and provides gentle, even heat across the room.
Two types are dry (electric) and wet (water-based):
Electric underfloor heating
- Electric underfloor heating requires low voltage electrical wiring positioned under the floor and should be easier to install in smaller spaces.
- This type of heating is energy efficient, since it can work with lower temperatures to offer comfort throughout the room.
Water-based underfloor heating
- Hot water systems use a pipe that is run from the boiler to push hot water under the floor providing consistent heat.
- This method is more expensive to install and when an area is large it may be more efficient.
- Professional installation is required for water based systems, but the upfront price is higher though with lower running costs, they represent a good economic option for large bathrooms or long term use.

Budget and energy efficiency
For choosing a bathroom heating option you should think about the installation cost and running costs. Assuming a three-bedroom house for instance, underfloor heating, especially water based systems, may have a higher up front cost but will often deliver better long term efficiency.
At the same time, electric heaters and towel rails would provide quick heat and little installation work for those looking for flexibility.
Depending on the type of heating system you use, some will be more energy efficient than others, and, as a result, some will prove to be costlier when running annually than others.
Installing an energy efficient heater can not only help the environment, but also help you save on your utility costs.
Practical installation tips
Due to safety regulations, bathroom heating installations must meet specific standards, as bathrooms are split into zones that determine which types of heating equipment can be used and where they can be placed.
As explained in the IET Wiring Regulations, these zones are defined by their proximity to water sources:
- Zone 0 covers areas within the bath or shower basin
- Zone 1 includes the area directly above Zone 0, up to 2.25 metres
- Zone 2 is the area within 0.6 metres horizontally from Zone 1
When installing any bathroom heating system, it’s best to consult a qualified professional to ensure safety compliance and efficient operation.
Proper placement can help reduce energy costs by ensuring heat is directed to where it’s most needed.
Final thoughts: Bathroom heating options
Selecting the right bathroom heating system can make winter mornings more pleasant and reduce the risk of damp-related issues in your bathroom.
From classic radiators to luxurious underfloor heating, each option has distinct benefits, and the ideal choice depends on your space, budget, and personal preferences.
