To safely use a space heater in a bathroom, ensure it’s designed for wet areas, keep it away from water sources, maintain a safe distance from flammable materials, never leave it unattended, and regularly check for damage.
Using a space heater in a bathroom requires extra precautions due to the combination of water and electricity. Follow these expert safety guidelines to stay warm without risking shock or fire hazards.
1. Use GFCI Outlets Only
Ground-fault circuit interrupter (GFCI) outlets are mandatory in bathrooms for good reason. They detect current leaks and cut power within milliseconds to prevent fatal shocks. Look for outlets with “Test” and “Reset” buttons.
How to Test GFCI Protection
- Press the “Test” button – power should immediately cut off
- Press “Reset” to restore power
- Repeat monthly to ensure proper function
For added protection, consider installing a GFCI circuit breaker at your main panel.
2. Choose Bathroom-Safe Heater Models
Only select heaters specifically designed for bathroom use with these features:
| Safety Feature | Purpose |
|---|---|
| ALCI Plug | Prevents electrical shock |
| Tip-Over Switch | Auto-shutoff if knocked over |
| Thermal Cutoff | Prevents overheating |
The Consumer Reports recommends models with appliance leakage current interrupters (ALCI) for bathroom use.
3. Maintain Proper Placement
Safe Locations
- At least 3 feet from shower/tub
- On dry, level surfaces only
- Away from towels and curtains
Danger Zones to Avoid
- Near sinks or toilet tanks
- On wet floors
- Under towel racks
Consider installing a wall-mounted heater to keep it safely out of reach.
4. Never Leave Unattended
Bathroom heaters should always be monitored when in use. Follow these rules:
- Turn off before showering/bathing
- Unplug when leaving the room
- Keep children and pets away
5. Regular Maintenance Checks
Perform these safety inspections monthly:
- Examine cords for fraying
- Clean dust from vents
- Test safety features
- Check for moisture damage
According to the NY Times Wirecutter, space heaters cause 25,000 residential fires annually – proper maintenance reduces this risk.
