You step out of a hot shower, the tile feels like a freezer aisle, and you towel off at record speed. Bathroom space heaters fix that by warming a small, damp room before you reach for the robe. After comparing 6 models, the Lasko CD08200 is the best fit: it puts out 1,500 watts, carries ETL certification and weighs 3.4 pounds.

What We Looked For in a Bathroom Heater for Small, Damp Rooms
A bathroom combines water, tight floor space and outlets that rarely sit where you want them. A heater that works fine in a bedroom can be the wrong choice here, so we ranked these models on the points below.
- Built for a damp room: We gave the most weight to heaters whose listings say they are made for bathroom use. Three of our picks use an ALCI plug that cuts power on a short or on contact with water. The Lasko CD08200 pairs that bathroom-approved plug with ETL certification and 1,500 watts in a 3.4-pound body, which is why it leads the list. The U.S. Consumer Product Safety Commission recommends choosing a heater certified by a nationally recognized testing laboratory.
- Enough wattage for a small room: Most bathrooms are small, so a standard plug-in heater has enough output. Five of our picks run at 1,500 watts and one tops out at 1,200 watts, which is plenty for a powder room where you only need to take the edge off. Several also drop to a 900-watt low setting that holds the temperature once the mirror has cleared.
- Tip-over and overheat protection: According to the CPSC, electric heaters need an automatic cut-off that turns them off if they tip over, and five of our picks list tip-over protection. The Amazon Basics Ceramic Heater adds overheat protection, a 900-watt low setting under its 1,500-watt high and a 43 dB noise rating. Its listing warns against use in bathrooms and other high-moisture rooms, though, so it belongs in a dry bedroom or office next to the bath.
- Thermostat and timer: A timer lets the heater shut itself off after you leave, and among our picks timers run from 1 hour to 12 hours. Two picks add a digital thermostat that adjusts from 41 to 95 degrees Fahrenheit in 1-degree steps. The Reaks Ceramic Heater has a 12-hour timer, an ECO mode that adjusts output to room temperature and ETL certification. It also switches between 1,500-watt and 900-watt settings and has an ALCI plug for bathroom use.
- Size and outlet placement: Bathroom outlets often sit beside the sink, so the heater has to fit on a small, level spot away from water. The smallest of our picks measures 8.2 by 5.9 by 5.5 inches, and the tallest stands 10.3 inches. The U.S. Fire Administration says to keep anything that can burn at least 3 feet away. The CPSC adds that a heater belongs on a level, hard, nonflammable surface, which rules out the bath mat.
We left out central furnaces and whole-house systems because they need professional installation, and a quick fix for a cold bathroom should not. Water heaters and heated blankets do a different job. We also skipped unvented fuel heaters without an indoor rating, since they create a carbon monoxide risk in a closed room. If none of our main picks suits your layout, the models below are also worth a look.
Other Bathroom Heaters Worth Considering
These are other bathroom heaters we looked at but did not put on our main list.
If you want a gentler low setting, the GiveBest Space Heater drops to 750 watts, compared with 900 watts on our alternative pick. It is rated for up to 200 square feet and adds an adjustable thermostat plus tip-over and overheat protection. It offers a different design and feature mix at the same 1,500-watt peak as our top pick.
A similar 750-watt low setting shows up on the Black+Decker BHDC201, which weighs 2.8 pounds, about 0.6 pounds less than our top pick. It keeps an adjustable thermostat along with tip-over and overheat protection. That makes it a reasonable swap if a lighter body matters more to you than the bathroom-approved plug on our top pick.
Lighter still, the Aubkn Space Heater weighs 2.2 pounds, against 3.4 pounds for our top pick. It runs at 1,500 watts with a 700-watt low setting and carries ETL certification. Its 12-hour timer matches the longest timer on our alternative pick.
And if you have a large primary bath, the Heat Storm HS-1500 is rated for up to 750 square feet with 5,200 BTU of output and an adjustable thermostat. At 9 pounds, it weighs about 2.6 times as much as our top pick. That extra weight makes it harder to lift out of the way when you clean the floor.
FAQs
Is it safe to use a space heater in a bathroom?
It can be, as long as the heater is designed for damp rooms. Three of our picks use an ALCI plug that cuts power on contact with water, while one pick’s listing warns against bathroom use entirely. The CDC recommends electric heaters with automatic shut-off switches and non-glowing elements.
How far should a bathroom heater sit from towels and the tub?
The U.S. Fire Administration and the CPSC both say to keep anything that can burn at least 3 feet from a space heater, and that includes hanging towels and bath mats. The CDC also says never to cover a space heater, so do not use one to dry a towel.
Should you leave a bathroom heater running after your shower?
No. The U.S. Fire Administration advises turning space heaters off when you leave the room, and it reports that portable heaters cause only 3 percent of home heating fires but 41 percent of fatal ones. Timers on our picks range from 1 hour to 12 hours, so set a short one if you tend to forget.
How many watts does a small bathroom need?
Our picks range from 1,200 to 1,500 watts, which covers a typical bathroom. Low settings of 900 watts on several models keep the room warm with less output once the initial chill is gone.
