8 Best Portable Bathroom Heater Reviews 2022

Instead of turning up the central heat in the morning, invest in the best portable bathroom heater to help save energy in the long term.

Bathroom heaters are intended to help you stay warm and enjoy the shower during those cold winter months. They heat the room instantly so you won’t have to wait for your primary heating system.

Modern bathroom heaters come with a lot of extra features that make your showers a lot more fan. However, it would be best if you always considered your needs first before selecting one for your home.

What type of heater are you looking for? What is the size of your bathroom? What is the wattage of the heater? These are some of the questions you must ask yourself before choosing the best small heater for the bathroom.

Benefits of a Bathroom Heater

The best portable bathroom heaterThe first thing you need to do is understand what makes a bathroom heater important. This will help you determine whether you need one in the first place. Portable bathroom heaters have four crucial benefits;

Warm your bathroom

The bathroom is the chilliest room in most homes. There are a couple of reasons for this, the main one being that bathrooms don’t have as much insulation as other rooms in the house. Another cause is the constant moisture. Portable bathroom heaters fix the chilliness by introducing a supplemental heating source.

Keep Out Mold, Mildew, and Odors

Moisture doesn’t just cause chilliness. It can also lead to the growth of mold and mildew. If left unchecked, it can even cause rotting, which can, in turn, result in odors. Warming the bathroom is the perfect remedy for the constant moisture. It keeps the moisture out and your fixtures dry.

Keep your Mirrors Clear

You might have also noticed that moisture in the bathroom causes your mirrors to fog. Fogging refers to the cloudiness you see on the mirrors that makes it impossible to see yourself. Drying out bathroom moisture using a portable heater can resolve the fog issue.

Extend the Life of your Bathroom Fixtures

We’ve mentioned the need to keep your bathroom fixtures dry. One benefit of keeping them dry is that constant exposure to water and moisture isn’t precisely good for all fixtures. Those made of metal, for instance, tend to rust quickly when exposed to moisture. Bathroom heating can help solve this problem.

Features to Consider when Choosing a Portable Bathroom Heater

Portable bathroom heaters are generally lightweight and easy to move from one place to another. But, they also differ in several ways. The following are top considerations when shopping for one;


Wattage will tell you two things about a heater. First, it tells you how much heat you can expect to generate with the heater. The higher the wattage value, the more the heat it produces. Secondly, the wattage will also tell you the cost of running the heater. Again, the higher the wattage value, the more it costs to run.

Coverage Area

How much space can the appliance warm comfortably? Remember that this isn’t entirely dependent on the wattage. It’s also affected by factors such as heat type (radiant or convectional) and a fan’s presence. Fortunately, most manufacturers prominently display the recommended coverage area for their products.

Size and Style Features

Portable bathroom heaters might be all small in size, but they are not all the same size. Make sure to find a unit that won’t take up too much space in your bathroom. Therefore, if you have a small bathroom, choose an even smaller heater. As for style features, colors, design style, and control features can add some style to your bathroom.

Heat Settings & Thermostat

The best portable bathroom heaters have easy-to-locate and simple to use settings and a thermostat to help with temperature regulation. In fact, for these heaters, a separately installed thermostat isn’t ideal. Instead, consider units that come with in-built thermostats.

Extra Features

As we mentioned earlier, the little extras are what make a portable bathroom heater great. Such features may include a timer that automatically turns on the unit a few minutes before you get to the bathroom and automatic shut-off for increased user safety.

Product Warranty

Finally, always check if there’s a warranty. Most bathroom heaters have one, but not all do. Additionally, warranty periods and the issues covered tend to vary. The best warranty lasts a long time (say a year or more) and covers many possible problems.  

Safety When Using the Best Portable Heater for Bathroom

safety precautions when using the best portable bathroom heaterMost portable bathroom heaters are generally safe. Most meet national and international safety standards and are equipped with vital safety features, including emergency shut-off and safe-to-touch surfaces. For added safety, consider the following tips;

  • Plug it into the main outlet: Electrical extension sockets aren’t very safe because most of them can’t handle the current needed for home heating. Plugging your heater into an extension socket, therefore, creates an overheating and burning risk.
  • Keep it away from water: You know what happens when the electric current comes in contact with water – electrocution. So, keep the unit as far away from water as possible and tuck away the cables for further safety.
  • Ensure regular maintenance: The bathroom heater can get clogged with hairs, debris, and other dirt particles. Use a blower to clean up the vents once a month for optimal performance.
  • Keep the kids and pets safe: Ensure that the unit is located in an area where it doesn’t pose a safety risk to the little ones and your pets.
