Can you put a wall heater in a bathroom?

Quick Answer

Yes, you can install a wall heater in a bathroom, but there are some important safety considerations to keep in mind. Wall heaters are required to be installed a certain distance from bathtubs and showers and must be on a GFCI circuit. Proper ventilation is also critical to prevent moisture buildup. As long as you follow all electrical and building codes, a wall heater can be a nice way to add supplemental heat to a bathroom.

Safety Requirements for Bathroom Wall Heaters

Installing any electrical appliance in a bathroom requires extra safety precautions because of the presence of water. Here are some key requirements for installing a wall heater in a bathroom:

• The heater must be installed at least 3 feet horizontally from the edge of any bathtub or shower stall.
• The electrical circuit powering the heater must be GFCI protected. This will provide protection in case of electric shock.
• The heater must be properly grounded.
• The heater must be installed high enough off the floor that it does not present a burn risk or be easily splashed with water.
• Any electrical outlets in the bathroom must be GFCI protected and located at least 3 feet from water sources.
• The heater should not be located directly under a bathroom exhaust fan.
• Proper ventilation should be provided to prevent excessive moisture buildup.

Always check your local electrical and building codes for any additional requirements when installing electrical appliances in bathrooms. Getting the proper permits and having the work inspected is also critical for safety.

Choosing a Wall Heater for a Bathroom

When selecting a wall heater for bathroom use, there are a few specific features to look for:

• Moisture-Resistance: Choose a heater that is designed for bathroom use and is resistant to moisture. Models with enclosed, water-tight heating elements are ideal.
• GFCI Plug: Select a heater with a built-in GFCI plug for added safety and convenience.
• Thermostat: Models with adjustable thermostats allow you to control the temperature setting.
• Safety Certification: Choose a heater certified by Underwriters Laboratories or another reputable safety testing organization.
• Wattage: Choose an appropriate wattage based on the size of the bathroom. Often 750-1500 watts is adequate for a small to medium-sized bathroom.

A fan-forced electric heater or an oil-filled radiant heater are good options for bathrooms. Avoid using unprotected space heaters or units not specifically designed for bathroom use.

Installing a Bathroom Wall Heater

Here are some step-by-step instructions for safely installing a wall heater in a bathroom:

Step 1: Turn Off Power

Turn off the power at the circuit breaker for any electrical circuit that will power the heater. Use a contact voltage tester to confirm power is off before proceeding.

Step 2: Install Electrical Box

If one does not exist already, install an electrical box for the heater. The box should be located at least 3 feet horizontally from any bathtub or shower.

Step 3: Run Electrical Wires

Run the necessary electrical wires from the circuit breaker panel to the electrical box. The circuit must be GFCI protected. Use appropriate gauge wire based on the amperage draw of the heater.

Step 4: Install Wall Heater

Mount the heater securely onto the wall according to the manufacturer’s instructions. Attach the wire connections—hot, neutral, and ground. Make sure all connections are tight and secure.

Step 5: Caulk and Weatherproof

Caulk around the heater mounting plate and electrical box to prevent moisture intrusion. Provide any necessary weatherproofing based on the heater location on an exterior wall.

Step 6: Test and Confirm Operation

Restore power and test operation of the heater. Make sure the GFCI outlet functions properly by pressing the “Test” and “Reset” buttons. Verify the thermostat and heating elements work correctly.

Step 7: Inspect and Get Permits

Have an electrician inspect the finished installation for safety. Obtain any required permits and schedule inspections by local building officials.

Following proper codes and installation methods is extremely important for safety when installing wall heaters in bathrooms. Consult a qualified electrician if unsure of any part of the process.

Maintenance Tips for Bathroom Wall Heaters

To keep your bathroom wall heater operating safely and efficiently, follow these maintenance recommendations:

• Clean dust and debris from around heating elements and fan guards regularly using compressed air.
• Inspect the exterior for any signs of damage or moisture intrusion.
• Test the GFCI outlet monthly by pressing the “Test” and “Reset” buttons.
• Check that heating elements are in good condition and not burned out.
• Make sure intake and outlet grilles are not obstructed by objects or dirt.
• Confirm that mounting hardware, electrical connections, and grounding are still secure.
• Check that insulation, caulking, and weatherstripping around the heater are still intact.
• Verify the thermostat is functioning properly.

Following the manufacturer’s maintenance instructions can also help prevent issues. Promptly repairing any damage or replacing worn parts will help ensure safe operation.

Safety Tips for Bathroom Wall Heaters

Improper use can make any wall heater unsafe. Keep these safety guidelines in mind:

• Keep electrical appliances away from water – never use near bathtubs or showers.
• Do not place towels or other objects on the heater.
• Check for damaged plugs or cords – discontinue use if found.
• Do not use if the exterior is damaged.
• Never leave operating heaters unattended.
• Always turn off when not in use.
• Keep air intakes and outlets clear.
• Do not attempt to repair yourself – seek professional help.
• Do not exceeding the heater’s rated wattage.
• Keep children and pets away from operating heaters.

Proper use, maintenance, and following safety guidelines will help ensure your bathroom wall heater provides warmth safely for years to come. Seek professional assistance if ever in doubt.

Conclusion

Installing a wall heater in a bathroom can be a nice way to provide supplemental heat, but does require taking some additional safety precautions. As long as the proper electrical codes and installation guidelines are followed, a wall-mounted electric or radiant heater can be a good heating option for small to medium-sized bathrooms. Choosing a moisture-resistant model designed for bathroom use and ensuring proper placement, ventilation, and GFCI electrical circuits are key. With routine maintenance and safe operation, a bathroom wall heater can provide extra warmth and comfort for your daily routine. Just be sure to consult professionals if ever in doubt during installation or repair.
