Can You Use a Heater in The Bathroom? [Top 3 Safe Bathroom Heaters]

Can you use a heater in the bathroom?

Heaters have been known to be man’s reliable companion when the blistering winter winds come around. In the thick of winter when snow falls heavily on our homes, it is very likely to find smoke coming out of the chimney of certain houses, especially those built before 1970.

Today, there are other alternatives that allow you to use electricity and propane, and also focus on heating in specific rooms and spots. This is why you can have a heater in that one room in your home where heating is most needed.

But what about bathrooms? While you can use portable heaters in your bedroom, living room, and other parts of your home, is it also possible to use them in the bathroom?

Are there concerns about electrocution or even damage to the appliance itself? And if you can use them in bathrooms, are there safety precautions to consider? These are some of the questions we’ll answer in this post, and we urge you to stay with us.

Top 3 Safe Heaters for Bathrooms

Is It Safe to Use Heaters in A Bathroom?

For most people, this is a resounding No, and we can understand why. The thought of having an electrical appliance close to water or water vapor can be quite scary, and rightly so.

In fact, the U.S. Consumer Product Safety Commission (CPSC) warns that you should NOT use electric heaters in bathrooms.

This was as far back as 1990 and was issued after several accidents involving the use of electric heaters in Missouri, Illinois, and several other states in the country.

However, that was more than 20 years ago, and while the danger is still very much present, there are now ways to get around using heaters in the bathroom.

For starters, there are now many wall-mounted propane heaters you can use in the bathroom, as long as the bathroom has an outer wall, the unit’s input rating is well below 6,000 BTU, and there is an Oxygen Depletion Sensor (ODS).

Central heating systems may also be connected to the bathroom, depending on the design.

But let’s focus on portable heaters. Using Ground Fault Circuit Interrupters (GFCI) is one way to safely use a heater in a bathroom. In fact, GFCI outlets are a legal requirement for bathrooms in the US built since 1975.

The outlet is designed to automatically shut off power when fluctuations in current occur. This can be due to contact between vapor/water and the unit.

They are also pretty sensitive and reliable that even the CPSC admits that the GFCI will detect and shut off power for as little as a slight current interruption of 0.006 amperes.

Also, the quality of the heater you use is a factor. Cheap, low-quality heaters under $30 are usually not what you need in a bathroom, except for a few exceptions.

Apart from wearing off and rusting away due to water vapor, they are also less likely to have protection against electrocution in case of contact with water.

Instead, get a powerful space heater that heats up fast and adequately. By getting hot, the heater protects itself- evaporating the water around it and in the air and dehumidifying the room in some way as well. Also, the high heating power means you don’t have to leave it on for too long.

But beyond getting a top-quality heater for your bathroom, where you place it matters a lot. You should never drop your space heater on the side of your bathtub or hanging above it.

You should also never keep it close to the shower area. The best spot is close to the exit door and close to the floor as possible, or even on the floor.

Most accidents involving a heater in a bathroom occurred because the appliance fell into the bathtub causing electrocution. By leaving it on the ground, there’s no chance of it falling into the bathtub, or even falling at all.

Can I Use a Heater While I Shower?

Can you use a heater in the bathroom? What Kind of Heater Is Safe for The Bathroom?

You certainly can, as long as it is a top-quality heater, with some level of protection against electrocution from contact with water. Also, ensure that you have a GFCI installed in your bathroom and that the heater is placed on the ground far away from the bath area.

Also, you need to ensure that there is no continuous splashing of water on the unit. While quality heaters may withstand water vapor, they cannot withstand contact with high amounts of water.

You also need to shut off the heater from the outlet once you step out of the bath area or tub, to prevent your wet body from coming in contact with a running heater.

After showering, ensure you air the bathroom to allow water vapor to escape. Otherwise, it may settle on your heater and cause some damage. You can simply open the windows and doors, but if you have a ventilator, that’s an even better option.

What Kind of Heater Is Safe for The Bathroom?

Sadly, waterproof and weatherproof electric heaters are often built for outdoor patio use. You can talk to your local electrician or HVAC professional to see if any of those fit in your bathroom.

As long as it’s not hanging over your tub, you should find something that works. However, there are some indoor space heaters built with certain safety features that can work well in your bathroom.

Important safety features to look out for in bathroom heaters:

1. Automatic Shut-off Switch

This will shut down the unit when there’s a surge or interruption in the flow of current.

2. Tip-over Protection

With such a feature, the unit automatically shuts down when it is tipped over. This can help avert accidents in your bathroom.

3. Cool-touch Exterior

This is another safety feature that you should look out for in a heater whether in your bathroom or elsewhere in your home. Burns and injuries can be prevented.

4. Non-conductive Exterior Casing

It is better to purchase a heater with a plastic or other non-metallic, non-conductive outer casing. This can help to prevent electrocution if water touches the body.
