The bathroom is an intimate space where we spend plenty of time getting ready in the morning, showering, and answering mother nature. As such, it should have warm air. Taking a shower or brushing your teeth in a freezing bathroom is very uncomfortable.

One of the best ways to make your post-shower experience enjoyable is by using the best bathroom space heater. Space heaters are bathroom accessories that give you much-needed warmth, especially during the cold winter. They are a fast and economical way of warming your bathroom.

What to Look For in a Bathroom Heater

1. Power Rating

The power rating of your bathroom space heater gives you an idea of its performance. Generally, a higher power rating gives better heating results. Therefore, always go with the highest power rating possible. The common power rating in most space heaters for bathrooms includes 750 watts,  1000 watts, 1500 watts, and 2000 watts.

2. Heater Types

Your needs will determine the type of space heater you need for your bathroom. If you wish to buy a bathroom heater that will function throughout the year, consider buying a ceiling heater.

It does not get in your way, and you can easily control it with a remote. If you have small children and pets, a wall-mounted heater is an excellent option, and it is barely noticeable if installed correctly. 

Another type of heater you can consider is the bathroom exhaust fan, which includes infrared lights. They are safe but do not have a large heating capacity like their propane and electric heater counterparts. 

The most common type of bathroom heaters is portable heaters because they are multifunctional. You can use them in any room and move them as frequently. You can also store them when they are no longer in use.

3. Controls and Modes

A powerful space heater for bathrooms should offer controls, modes, and features to make it effective. Without such, it will be utterly useless, no matter how powerful. These controls and modes make your space heater very practical and versatile. The common controls and modes to look for when purchasing a space heater for the bathroom include the heating mode, the temperature setting, fan speed, the timer setting, etc.  

4. Safety

It is important to consider safety features when purchasing space heaters for the bathroom. Bathrooms are the wettest areas in a home, and when using electric wall heaters, you need to consider certain specifications to ensure your safety and that of your family. Specifically, ensure that your heater has ALCI plugs that provide an extra layer of safety,  as these are specifically made to resist moisture. 

Heaters made with fire retardant material will protect you against fire accidents. Ensure your heater has built-in safety measures that shut it off if it overheats. If you have a standalone heater, ensure it has an anti-tip feature to prevent it from catching fire in case it falls or bends. 

Look out for timers in your heater. They are great in preventing you from overusing the heater or leaving it on while not in use. 

5. Recommended Area

The recommended area rating indicates the performance of your bathroom space heater. Many space heaters for bathrooms mention the maximum area of a room that can be heated using that space heater. This rating gives you a good idea of whether your space heat can effectively heat up the space you are purchasing it for.

The most common recommended area rating is 100 square feet, 150 square feet, and 200 square feet. Generally, a space heater with a rating of 200 square feet is more than enough to heat your bathroom.

6. Installation

If you are purchasing a portable space heater for your bathroom, it will require no installation. However, if you buy an exhaust fan heater, you must open an existing exhaust fan to put the infrared feature. 

Wall-mounted heaters require external wall mounts, which you can easily get online or at a local hardware store. Ceiling heaters, on the other hand, are more complex and will require a higher level of expertise to install. It involves cutting into your ceiling, so you should engage professionals, especially when electric work is involved. 

7. Size

 If you are mainly looking for a portable space heater, consider the weight and size of the unit. Some space heater units weigh as low as three pounds, while others weigh as much as 30 pounds. Strike a balance between portability and strength because lighter units produce less heat than larger units.

Frequently Asked Questions About the Best Space Heater for Bathrooms

1. How does a space heater for bathrooms work?

All electric space heaters for bathrooms use electric coils to produce the heat that is used to heat up the bathroom. These electric coils conduct heat, making them produce the heat used. The space heater has several of these coils, making them effective for use in heaters. 

2. Which one is better, the infrared heater or the ceramic heater?

Ceramic heaters conduct heat using ceramic plates and aluminum baffles. Due to their small size, they are incredibly efficient in heating and extremely portable. Also, they can heat a wider range of areas. On the other hand, infrared heaters work very well even in poorly ventilated areas because they focus on heating people directly rather than warming the air. And since they use radiant heat, they are the best for extended periods. They consume 60% less energy than convection heaters to give the same level of heat and comfort. 

3.  Are space heaters for bathrooms resistant to water damage?

Although bathroom space heaters are safe, they are not water resistant. Since most of them use electric coils to heat the air, the water can go into these coils and get spoiled. However, some space heaters are made with waterproof and condensation-proof material, making them resistant to any water damage. 

4. Is it safe to leave a space heater ON all night?

It is unsafe to leave a space heater in the bathroom all night. Although the space heaters have built-in safety measures, avoid leaving your heater ON unattended in the bathroom. If the auto shut-off malfunctions, it can cause fire accidents.

Also, leave a perimeter of around three feet around the unit to avoid accidents. Kids and pets can reach the unit at night without your knowledge and get burned.

5. What is the benefit of having a fan inside a bathroom space heater?

Although not all bathroom space heaters have an inbuilt fan, most have one. The fan helps in better convection of the produced heat produced by the space heater. This increases their efficiency and helps the heater to work faster.
