You step out of a hot shower and the tile floor feels like the freezer aisle at the grocery store. A small heater fixes that in a few minutes without warming the whole house.

What We Looked For in a Bathroom Heater for Small, Damp Rooms
A bathroom is the hardest room in the house for a heater. It is small, it gets wet, and the only outlet usually sits right next to the sink, so the usual space heater priorities shift.
- A safe design for a damp room: Getting the heater off a wet floor and away from towels is the first job. The Broan-NuTone Wall Heater goes into the wall itself, carries a UL listing, and runs at 2,000 watts with a 1,000-watt low setting. It weighs about 6 pounds and the maker recommends professional installation, so treat it as a permanent fix rather than something you carry from room to room. Among the portable picks, one uses an ALCI safety plug that cuts power on contact with water, and the U.S. Consumer Product Safety Commission advises choosing a heater certified by a nationally recognized testing laboratory.
- Wattage for a small room: Most bathrooms do not need the 1,500 watts a living-room heater draws. The Amazon Basics Ceramic Heater uses 500 watts, enough to warm the space right around you while you dry off. It is also quiet at a listed 48 dB and weighs 1.4 pounds, so it moves easily off the counter. Across our picks, output runs from 500 to 2,000 watts, and two of them sit at the 500-watt end.
- Tip-over and overheat protection: The CPSC says electric heaters should have an automatic cut-off that turns them off if they tip over. Three of our picks list tip-over protection, and five of the six list overheat protection or a thermal cut-off. The 2 wall-mounted picks are fixed in place, so they lean on overheat protection instead. The Centers for Disease Control and Prevention also recommends electric heaters with automatic shut-off switches and non-glowing elements.
- Thermostat and timer: A thermostat keeps a heater from running flat out in a room that is already warm. Four of our picks have adjustable thermostats, and two add a 12-hour timer. The Good Housekeeping Wall Heater pairs a 750-watt output with both, plus a digital display. Its timer works in 1-hour steps, so it shuts itself off instead of running all day.
- Size and outlet placement: Bathroom outlets tend to sit beside the sink, so a heater has to fit on a small dry surface or on the outlet itself. The two smallest picks measure about 6 inches on their longest side, while the largest portable model is 10.3 inches. One pick plugs straight into the wall with a 180-degree rotatable plug, which keeps it off both the floor and the counter. The CPSC advises a level, hard, nonflammable surface, so keep any heater off bath mats and rugs.
We left out central furnaces and whole-house systems because they need professional installation and do far more than warm one small room. Water heaters and heated blankets do a different job entirely. We also skipped unvented fuel heaters without an indoor rating, since they bring a carbon monoxide risk into a closed room, and a bathroom with the door shut is about as closed as a room gets. A few more electric models came close, and they are worth a look if your bathroom is larger than average.
Other Bathroom Heaters Worth Considering
These are other bathroom heaters we looked at but did not put on our main list.
If you want more output than our top pick, the Lasko CD08200 delivers 1,500 watts, three times the 500 watts of our top pick. It is ETL certified, which lines up with the CPSC advice to buy a heater checked by a recognized testing laboratory. At 3.4 pounds it is still easy to move, but a full 1,500 watts is more than a small powder room usually calls for.
Need that same power with a gentler option? The Black+Decker BHDC201 also runs at 1,500 watts and steps down to 750 watts, with an adjustable thermostat and both tip-over and overheat protection. At 2.8 pounds it is double the weight of our top pick, which matters if it lives on a narrow vanity.
That same 1,500-watt and 750-watt pairing shows up on the GiveBest Space Heater, which is rated for up to 200 square feet. That coverage makes more sense for a large primary bath than for a compact guest bath. It also includes an adjustable thermostat plus tip-over and overheat protection.
And if you want a middle ground, the QQT Ceramic Heater sits at 1,200 watts, 700 more than our top pick, with tip-over and overheat protection. It weighs 2 pounds, still light enough to lift off the counter when you need the outlet for a hair dryer.
FAQs
Is it safe to use a portable heater in a bathroom?
It can be, as long as the heater shuts itself off when tipped or overheated and stays away from water. According to the CPSC, portable and fixed local heaters were tied to about 10,900 residential fires in a recent year. Pick a model certified by a recognized testing laboratory and keep it on a dry, hard surface.
How many watts does a bathroom heater need?
Our picks range from 500 to 2,000 watts. A 500-watt or 750-watt unit is enough to take the chill off a small bathroom, while 1,500 watts suits a larger room or a colder house.
Should I leave a bathroom heater running when I leave the room?
No. The U.S. Fire Administration says to turn space heaters off when you leave the room or go to bed. Portable heater fires were only 3 percent of home heating fires over a recent three-year period, but they accounted for 41 percent of the fatal ones. A timer, which two of our picks offer at up to 12 hours, adds a backup if you forget.
Where should a heater go in a small bathroom?
Keep it at least 3 feet from towels, shower curtains and anything else that can burn, as both the CDC and the USFA advise. Never cover it, and set it on a level, hard surface rather than a bath mat. If floor space is tight, a model that mounts on the outlet or the wall keeps it out of the way.
