Bathroom Heater Buying Guide 

bathroom heater mounted on a wallWhen shopping for a bathroom heater, there are several factors and considerations you need to keep in mind. The rest of this guide is intended to help you select the best product to suit your needs. Let’s start with why one would need a bathroom heater.

 What are the benefits of a bathroom heater?

A heater for your bathroom comes with three main benefits; 

  • Gets rid of moisture and foul odor: Many homeowners already use exhaust fans to keep the bathroom dry and free of foul smells. Unfortunately, that’s rarely enough. Even the most powerful exhaust fan may not prevent moisture from accumulating in your bathroom and fogging your mirrors. Bathroom heaters are excellent at keeping the bathroom dry, fending off mildew, mold, and slippery floors. By keeping the bathroom dry, the heaters also keep away foul odors.
  • Keeps your bathroom warm: Another reason you should consider installing a heater in your bathroom is to fend off morning chills. This would be especially important if you take your showers in the morning. During the winter season, the bathroom can be freezing. A bathroom heater would help warm up the area so you can enjoy every moment spent in the bathroom. 
  • Keeps the environment dry: Finally, a bathroom heater also keeps the floors and walls dry. After a shower, you’re likely to have spilled water everywhere, especially on the floors. A wet floor is a huge safety hazard; it only takes one misjudged step for the occupant to slip and fall. Depending on the flooring material, a slip-and-fall accident in the bathroom can lead to various degrees of injuries. A bathroom heater keeps the whole place dry, significantly reducing the risk of slipping.

Types of Bathroom Heaters

If you’re excited by the benefits of bathroom heating, the next step is to learn about the different types of bathroom heaters. There are three broad categories of bathroom heaters;

  1. Portable heaters: Portable bathroom heaters are small and easy to maintain. As the name suggests, they are portable, i.e. can be carried around the home with ease. However, they’re also durable and specially designed to withstand temperature, fumes, and moisture. Most portable bathroom heaters are built with heat-resistant polyethylene (sturdy plastic) while others are made from aluminum. The heaters also feature an ALCI plug that prevents water from penetrating the plug and potentially causing trouble inside the heater. 
  2. Wall heaters: When it comes to wall-mounted electric heaters for bathrooms, there are two subcategories to choose from; built-in and detachable. Built-in bathroom heaters are installed into the wall. A hole is drilled into the wall so that the entire electrical network is tucked away and remains out of sight. Detachable bathroom heaters, meanwhile, is installed on a metal frame. The frame is screwed to the wall, and then the heater is either slid into or screwed to the frame. In this setup, the wiring network is visible and runs across the bathroom wall. 
  3. Ceiling heaters: Ceiling fan heaters are similar to wall heaters, the most significant difference being that they are installed on the ceiling rather than on the wall. Most ceiling bathroom fans are permanent fixtures installed by professionals. A hole is drilled into the ceiling, and the heater installed into that hole, with the wiring tucked away. Since they sit high above on the ceiling, the heaters can’t be obstructed and are much safer than both portable and wall heaters. 
  4. Radiant floor heaters: Finally, you could also opt for radiant floor heating systems for bathrooms. The most popular heating method in this category is baseboard heating. These heaters have a minimal footprint so, don’t take up much space. They also produce significant amounts of heat without consuming a lot of electricity.  

Most baseboard bathroom heaters are plugged into a wall outlet while others need to be wired into the home’s electric wiring system. One downside, however, is that they take longer to warm up a room. A standard baseboard bathroom heater can take a whole two hours to raise bathroom temperatures to the desired level. The great news, though, is that they keep radiating heat long after the unit is turned OFF.

How to Select a Bathroom Heater

installed space heater for bathroomAside from heater type, there are at least five other critical factors to consider when choosing a bathroom heater. These are;

  • Heater Footprint 

The term “footprint” refers to the amount of space the heater takes up. Since space is at a premium in the bathroom, you should aim for heaters that take up as little space as possible. Fortunately, most bathroom heaters are designed with this in mind.

Ceiling bathroom heaters, for example, take up no space valuable space in at all. That’s because the ceiling heaters rests on the ceiling. They won’t interfere with movement in the bathroom at all. They also don’t block the water source.

Wall mounted water sources take up a bit of space, but not so much as to block your way around the bathroom. The same applies to radiant floor heaters. The only heater types that may impact free movement in the bathroom are portable heaters. Although small, they still take up some space. You may even have to change your routes in the bathroom to avoid knocking down the heater. 

  • Permanent or Temporary

Another crucial consideration is the permanency of the heater. Bathroom heaters can be permanent or temporary. 

If you’re interested in a permanent heating fixture, ceiling and some wall mounted heaters are the best options. Two key advantages of permanent heating features are durability and extended warranties. The major downside, however, is that they are more difficult and costly to install. Permanently installed bathroom heaters are a great option if you’re the owner of the property. 

Temporary heaters are mostly portable types. Their biggest advantage is their mobility – the heaters can be moved around with ease. You can carry the heater to the bathroom when needed and take it back into the garage for storage when you’re done. Another reason to consider portable bathroom heaters is their low price.

Compared to permanent heating fixtures, portable options are significantly cheaper. The drawback, however, is the higher risk of breakage/damage. Temporary heating is an excellent option for tenants of if you expect to move out of the house soon.

  • Heater Efficiency 

Electricity is the most expensive fuel for home heating. Therefore, it’s prudent that you consider high-efficiency bathroom heaters that doesn’t consume too much power. Studies show that wall/ceiling heaters are the least energy efficient followed by portable heaters, with baseboard (under-floor heaters) being the most energy efficient 

What makes wall/ceiling heaters rather inefficient is that they don’t retain much heat. With wall heaters, you only get for the period that the heater is on. When you turn OFF the heater, the climate in the bathroom will be back to its previous cold state within seconds.

Another thing is that in wall/ceiling heaters, the heat is blown straight in front of the unit; it’s not spread out at all. This often leads to uneven heating, further contributing o inefficiency. 

Portable bathroom heaters work almost the same way. They don’t retain much heat. The difference, however, is that most portable bathroom heaters radiate heat in all directions, resulting in faster space heating. 

If you’re solely after heating efficiency, then baseboard (under-floor) heaters are the heaters for you. Like other electric heaters, they use significant amounts of electricity to warm up. But, once they’re warm enough, only a small amount of power is needed to keep them at the desired temperature. Even better, baseboard heaters are excellent at heat retention. Even half an hour after turning OFF the heater, you’ll still have sufficient warmth in the bathroom. 

  • Heat-Up Duration

Finally, it’s also important to consider the heat-up time or the amount of time the heater takes to raise the temperature in the bathroom to the levels you desire. 

Here, wall and ceiling heaters are the clear winners. As already mentioned, wall and ceiling heaters blow warm air directly through the front into your bathroom. Depending on the model, it only takes seconds to get the bathroom to the set temperature.

Portable bathroom heaters also work this way. But, since most of them are smaller than wall/ceiling-mounted heaters, it could take slightly longer to attain the desired temperatures.

 Under-floor baseboard heaters, however, take significantly longer to warm up. If using a baseboard heater in your bathroom, you may need to turn on the heater up to 30 or more minutes before bathroom time. 

Bathroom Heater Safety 

best wall mounted bathroom heaterBathroom heaters are generally safe. But that doesn’t mean that nothing can go wrong. The risk of electrocution and even fires, though negligible, is always there. The following tips should help keep you, your loved ones, and your home safe;

  • Buy the right heater: Safety starts with buying the right heater for the bathroom. Not all space heaters are designed for use in wet/humid areas; make sure your model is approved for use in the bathroom. In short, make sure it’s a bathroom heater. This is especially important when buying portable heaters. Using a heater not approved for wet/humid areas into the bathroom creates unnecessary electrocution risk. Additional, exposure to such conditions can damage the heater.
  • Don’t soak it in water: Even if it’s a waterproof bathroom heater designed to withstand humid conditions, intentionally soaking the unit in water is not advisable. First off, the heater is connected to an electric source and water is a good conductor of electricity. So, there’s a risk of electric shocks. Secondly, knowingly getting your heater wet is one of the quickest ways to damage the unit.
  • Install the heater in the right place: Where you install or place the heater is vital. If it’s a permanent ceiling or wall heater, install it in a position where it doesn’t stand in the way of occupants. You don’t want a situation where the bathroom occupant regularly brushes cross the heater when entering or leaving the bathroom, or grabbing something. Also, install or place your heaters in a position where they won’t come in contact with too much water or humidity.
  • Keep portable heaters away from traffic: One of the biggest downsides of portable electric heaters is the risk of being knocked down. Perhaps you’re in a hurry and carelessly place the heater somewhere on the floor close without thinking about the consequences. If it gets knocked over, there’s a risk of fire. For this reason, identify a safe location for your portable bathroom heaters and always double-check that the heater is in that spot.
  • Invest in an extinguisher: This might come as a surprise, but, yes, you’ll need a fire extinguisher if you don’t have one already. Electrical fires are rather stubborn and aren’t extinguished in the same way as other fires. Even if you never use it, it’s better to be safe than sorry.

How Much Does It Cost to Run an Electric Bathroom Heater?

Unfortunately, there’s no straightforward answer here. Different types of bathroom heaters consume different amounts of electricity and thus cost different amounts to run. Here’s what we know;

Baseboard (under-floor) heaters take the longest to warm up the place sufficiently. But, once they reach the desired temperature, they require the least amount of electricity to maintain the set temperature. Also, they keep radiating heat for up to half an hour or more after you turn off the power. However, with some models in this category requiring up to one hour or more to reach the set temperature, they are not the best choice cost-wise.

Wall and ceiling heaters are a much better choice. Although they have poor heat retention, they warm up the place fast. The good news is that when it comes to bathrooms, this is precisely what you want – fast heat-up.

Not many people spend a whole hour in the bathroom, so the heat-retention qualities of under-floor heaters may not benefit many of us. If you’ll be spending less than 30 minutes in the bathroom, this would be a great cost-effective option. 

Portable bathroom heaters, however, are a mixed bag. Since the heaters come in many different styles and materials, cost-efficiency is determined by the model you choose. Portable ultra-red heaters warm the objects in the room, including you, without warming the air. They also deliver instant radiation. Other types use PTC ceramic element to produce heat. They work in the same way as wall/ceiling heaters, but use up less power.  

How to Install a Bathroom Heater

Going by the heater types discussed earlier, you can already tell that the installation process varies from one heater to another. In this section, we’re only going to discuss how to install wall heaters are they are the most common bathroom heaters. More importantly, to avoid costly mistakes and safety hazards such as electrocution, the installation process should be left to a professional

That said, assuming that you have the heater as well as installation tools and materials at hand, proceed as follows;

  • Find the Electrical Circuit

The first thing you need to do is to identify the electrical wiring branch that passes through your bathroom and the short circuit that controls it. This step can be a lot simpler if you have an existing exhaust fan in the bathroom as you’d be able to use the same electrical circuit. If there’s no exhaust fan, you’ll have to bring a new circuit from the main electric panel that supplies light to your bathroom. 

Ensure that the panel has at least one empty circuit breaker – two if you’ll be installing a thermostat too. Where there’s no empty circuit breaker in the said electric panel, you’ll need to call a licensed electrician to handle this step. Otherwise, proceed to step two. 

  • Turn OFF Power

Never begin any electrical installation with electric power ON. It exposes you and even the home to serious safety hazards. So, begin by turning OFF the circuit breaker the bathroom branch. Use a tester to verify that the power on that line is indeed OFF. 

  • Identify a Location for the Heater

In a situation where you have an exhaust fan, you can install the bathroom heater in the fan’s place. But, where there’s no fan, you’ll need to identify an optimal location. An ideal location for a wall heater is at chest-height, a few feet away from the bathtub/shower, and at least three inches away from flammable items such as towels, curtains, etc. Any of the four bathroom walls is allowed.

Since a wall heater goes at least 4 inches into the wall, choose a solid wall. Then, create a cavity that can hold a 4 x 2 (inches) metal frame. Remember to keep away from plumbing, electrical wiring, heat vents, and ducts running across or buried in the wall.

  • Hardwire the Heater

The manufacturer’s manual should guide you through this process. Just remember that the majority of bathroom heaters use 240V electricity, so you’ll need to connect both the white and black wires. Wrap tape around both wires and tuck them away into the back of the framing. Mark the white wire as “hot wire.”

  • Finish Up and Test your Heater

In this final step, ensure the heater is secured to the frame, and the wires aren’t hanging out loosely. Then, turn the circuit breaker back ON and test the new heater. If you followed all the five steps, it should work.


Now that you’ve considered some of the best bathrooms space heaters currently available on the market, it’s up to you to decide which specifications are most important to you.

There are a wide variety of options to suit every preference, so the best thing you can do before purchasing a bathroom heater is to make a list and prioritize the most important features.

For example, if you lead a busy life, you might find that a thermostat is absolutely essential. If you have a small bathroom space, the dimensions might take preference over anything else. With all of the information provided in this article, however, the final decision will be much easier.
