You step out of a hot shower, and the tile under your feet feels like it came out of the freezer. Electric bathroom heaters fix that by putting quick, focused warmth into a small room for the few minutes you need it. After comparing 4 models, the Fanspex Space Heater is our top pick for its 1,500-watt output, a 750-watt low setting and an adjustable thermostat backed by tip-over and overheat protection. The Dreo Space Heater is our alternative pick, with a 900-watt low setting and a water-sensing safety plug.

What We Looked For in a Bathroom Heater for Small, Damp Rooms
A bathroom is a hard place for any heater. Water splashes, floor space is tight and the nearest outlet is rarely where you want the heat, so we judged every model on the points below before anything else.
- A safe design for damp rooms: None of our 4 picks is wall-mounted, so the bathroom-specific protection has to come from the heater and its plug. Two of our picks use an ALCI safety plug that, according to their listings, shuts the heater off as soon as it detects contact with water or a short. The other two rely on standard protections, so they belong in a dry corner well away from the tub and sink. The U.S. Consumer Product Safety Commission also advises choosing a heater certified by a nationally recognized testing laboratory, and two of our picks list ETL certification.
- Wattage for a small room: All four picks top out at 1,500 watts, which is more than enough heat for a typical bathroom. In a small room, the low setting matters just as much, and our picks drop to between 750 and 900 watts. The Fanspex Space Heater has the lowest step at 750 watts, exactly half its high setting. That lets you take the chill off a compact bathroom without turning it into a sauna, while its thermostat knob cycles the heater on and off to hold the temperature you choose.
- Tip-over and overheat protection: According to the CPSC, an automatic cut-off is required to turn off electric heaters if they tip over, and all four of our picks list a tip-over switch. Each of them also lists overheat protection, which matters in a small room where warm air builds up fast. The U.S. Fire Administration notes that portable heater fires made up only 3 percent of home heating fires but 41 percent of fatal ones. That gap is why we did not consider any model without both switches.
- Thermostat and timer: A thermostat stops a heater from running at full power in a room that is already warm, and a timer keeps it from running after you leave. Two of our picks offer a timer of up to 12 hours. The Reaks Ceramic Heater pairs its 12-hour timer with an ECO mode that adjusts the heat to the room temperature, and it switches between 1,500 and 900 watts. You can set it before a shower and let it shut itself off afterward. The digital controls on our alternative pick go further, letting you choose a temperature from 41 to 95 degrees Fahrenheit in 1-degree steps.
- Size and outlet placement: Bathroom floor space is limited, and the CPSC says to place a heater on a level, hard, nonflammable surface rather than a rug. It also advises keeping a heater at least three feet from flammable materials, which in a bathroom means towels and bath mats. The Amazon Basics Ceramic Heater weighs 3 pounds, slightly under the 3.3 pounds of our top pick, and measures 7.5 by 6.3 by 9.5 inches. That footprint fits on a narrow strip of tile near an outlet. Its listed noise level of 43 dB also keeps it from competing with the bathroom fan.
We left out central furnaces and whole-house systems because they need professional installation, and that is not what you want for a quick fix in 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 carry a carbon monoxide risk indoors, and a closed bathroom is the last place to take that chance.
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 familiar name with the same output as our top pick, the Lasko CD08200 delivers 1,500 watts and carries ETL certification. At 3.4 pounds, it weighs only a tenth of a pound more than our top pick. The choice between them comes down to design and controls rather than heat.
Shaving weight is where the Black+Decker BHDC201 stands out: at 2.8 pounds, it is half a pound lighter than our top pick. It mirrors the top pick’s 1,500-watt high and 750-watt low settings, along with an adjustable thermostat and tip-over and overheat protection. That makes it a reasonable swap if you prefer its shape or controls.
Want a coverage figure before you buy? The GiveBest Space Heater is rated for up to 200 square feet and uses the same 1,500-watt and 750-watt settings as our top pick. Its adjustable thermostat and tip-over and overheat protection put it close to our main list, and it missed out on its design and feature mix rather than on heat.
And if floor space is the whole problem, the Dreo Wall Heater is the one to look at, rated for up to 750 square feet with a listed noise level of 28 dB. It weighs 6.1 pounds versus 3.3 pounds for our top pick. That makes it less of a grab-and-go heater and more of a fixture that stays put.
FAQs
Is it safe to use an electric heater in a bathroom?
It can be, as long as the heater has the right protections and sits away from water. Two of our picks add a safety plug that cuts power on contact with water, and all four list tip-over and overheat shutoff. The CDC also says never to cover a space heater, so keep towels off it at all times.
How many watts does a bathroom heater need?
Our picks all reach 1,500 watts on high, which warms a small bathroom quickly. Their low settings run from 750 to 900 watts, and that lower step is often all a compact room needs once the chill is gone.
Where should a heater go in a small bathroom?
Set it on a level, hard, nonflammable surface such as tile, not on a bath mat or rug, as the CPSC recommends. Keep it at least 3 feet from anything that can burn and as far from the tub and sink as the outlet allows.
Can I leave a bathroom heater running when I leave the room?
The U.S. Fire Administration says to turn space heaters off when you leave the room or go to bed. If you tend to forget, two of our picks have timers of up to 12 hours, so you can set a short run before a shower and let the heater switch itself off.
