As such, bathroom heating should not be neglected as it could serve to make a more comfortable experience whenever we enter the bathroom.

In this article, we will go through some of the best bathroom heaters in today’s market as well as the pros and cons of each of our recommendations.

Why Bathroom Heating?

The benefits of bathroom heating would include staying warm while in the bathroom. Secondly having a heating unit in the bathroom can help remove moisture or odours from the air. A bathroom heater is also shown to improve overall health by improving cardiovascular circulation, a bonus is that it can help with some muscle and joint soreness.

Finding The Best Bathroom Heaters

When it comes to finding a bathroom heater, several things in mind must be considered to find the best one suited to meet the individual’s needs. We will go through some of the key aspects to look out for when looking for a bathroom heater in this article.

First, are there different types of bathroom heating? Well yes, there exist a wide variety of types, but the most common are as follows.

Portable heaters

These are small heating units that are easy to carry around and require little to no installation. A portable heater can be brought around the house if it is not needed in the bathroom. Most portable heaters use an electrically powered heating element inside accompanied by a fan to force hot air out of the heating unit into the surrounding space.

Wall heaters

Wall heaters are wall-mounted heaters. They can be mounted on a hook or permanently via screws. Wall heaters are generally inexpensive, durable, efficient, and ideal for most smaller bathrooms.

Ceiling Heater

This kind of heating unit is generally more portable compared to the other types of heaters as they can be removed and reinstalled in other places relatively easily. As the name suggests, ceiling heaters are mounted on the ceiling and are known for being reliable and compact enough to not take up too much space.

Heater with exhaust fan

This is a good option for those looking for an appliance they can use all year round. Heaters with built-in exhaust fans are great for bathroom use as they can help reduce the humidity and steam in the bathroom. During the warmer months of the year, you can use the exhaust function of the heater.

Underfloor heater

An underfloor heater is a heating system that is laid underneath the floor of the bathroom flooring. It will heat the room by radiating heat through the floors. There exist subtypes of underfloor heating units, namely in-slab heating, thin-film heating, and screed heating. Underfloor heaters generally utilize electric or hydronic heating methods.

Is Bathroom Heating Costly?

The cost of the bathroom heating will depend heavily on the heating system that you have chosen to implement in your bathroom. Certain types of heaters like radiant bar heaters are more costly than others.

What to Look Out For

When purchasing a bathroom heater, there are a few aspects that should be considered, among those would include:

Optimized Heating

Given that most of us do not spend our whole days in the bathroom, or do not wish to wait too long before using the bathroom, it is important to look for a heater that does not take too long to heat the room. A quick method to determine the efficiency of the heater in question would be to measure the wattage output and British Thermal Units (BTUs).

The higher the BTU, the more energy-efficient the heater is.

Is it Durable?

A bathroom heater is no different from a heater when it comes to durability. When purchasing a heater, one should always look for a heater that requires little to no maintenance and can last for a long time (8-10 years).

Is it Safe?

When it comes to any electrical appliance, safety is of the utmost importance, especially in the bathroom. When selecting a bathroom heater, you should bear in mind that it is often both a humid and wet environment and appliances are therefore more likely to short circuit or malfunction.

It is important to note that not all space heaters are suitable for bathroom use. When purchasing a space heater for the bathroom, ensure that it is suited to function in a wet and humid environment. It is also advised that you should purchase a model with an automatic overheat protection feature.


The size of your heater will be dependent on the size of the room and is one of the most important factors to look at. Bathroom heaters that are too small for a large bathroom will not be able to heat the room quickly enough and will therefore leave you unsatisfied.

Whereas a larger heater could be too much for the small bathroom. This can lead to an unsatisfactory experience along with an expensive utility bill. A simple guide would be to keep 10 watts of power for every square foot.


The size of the heater selected could affect the budget of the heating appliance. Another factor that could affect the budget would be the type of heating technology used in the bathroom heater. If you choose to purchase a heating device such as an underfloor heater, the installation will require some renovation and could incur costs.

Types of Heating Technology

Heaters as discussed above come in a variety of heating methods. These methods can range from convection heating to infrared heating. The type of heating element used by the appliance can also determine the rate of warmth production and spread.

Placement of Thermostat

When installing an external thermostat, it is key that you do not place it near the heating device. If you do place it too close to the heating unit, it will not be able to properly gauge the temperature of the room and could make the room too warm or too cold. A recommendation would be to use a heating appliance with a built-in thermostat or mounter thermostat if the space is small.

What Should the Heater Do?

When looking for bathroom heaters, you should consider what functions you want the heater to have. Some bathroom heaters offer a multipurpose feature that allows them to do things such as removing humidity and heating the shower water. This can lead to a versatile heating system that can serve various functions.

This fan heating device is one to look out for if you own a smaller bathroom. This affordable fan heater is small enough to not take up too much space, which is essential if you do not own a larger bathroom. Features of the Holmes heater would include its ALCI plug.

A downside to this heating unit would be the loud fan which could pose a problem if you plan on using it during the night. Not only that, the warranty provided is only good for 1 year, which is not great in the event of short-term issues. The UI of the thermostat is also confusing at times and will therefore require some getting used to. These are all reasonable issues as this is a budget option.

5. Broan Model 157 Bathroom Ceiling Heater

Another product of the Broan brand makes its way onto this list with the Broan Model 157 Bathroom Ceiling Heater. This heating appliance is good for small to medium bathrooms.

When it comes to safety features, the product comes included with overheating protection which will shut it down if it overheats. There are LED light indicators that help with temperature control as opposed to a thermostat. The timer function can be handy in some situations and is a nice addition to this product.

The main downside to a product this complex is that there could be issues that arise during operation. This is only made worse as it only comes with a 6-month warranty.
