Getting out of bed is hard enough when it’s cold out, and the idea of venturing into a frigid bathroom makes it even more daunting. The best bathroom heater remedies this by warming up the space quickly and easily. With various types and sizes available, we’re here to help you find the optimal option for your area.
According to Josh Mitchell, an HVAC technician and plumbing expert, the best type of heater for a bathroom is typically a wall-mounted fan or a radiant floor heating system. Mitchell, who is also the founder of the Air Conditioner Lab and Plumbing Lab, notes that wall-mounted fan heaters are compact and can swiftly warm up small spaces, making them ideal for bathrooms. “They’re also typically installed high up on the wall, away from water,” he adds. On the other hand, he says, “radiant floor heating provides a more even and luxurious heat, warming the entire floor surface, which is particularly pleasant in a bathroom.”
The first step in choosing a bathroom heater is to determine your square footage to ensure your selection is properly sized. Do this by adding the length of each wall, and multiplying that number by the height of the room from floor to ceiling. The resulting number represents the square footage of the room. From the top portable picks to wall- and ceiling-mounted designs, we found the best bathroom heaters to cater to every need. Still looking for ways to keep your bathroom warm?

Just because you’re on a budget doesn’t mean you can’t enjoy a comfortably toasty bathroom. Affordable heaters can still produce enough heat to warm up smaller rooms, and they’re typically more compact and take up less space than more expensive options. This Minetom compact pick boasts a convenient and easy-to-use plug-in design.
Unlike some space heaters with limited settings, this model lets you set the digital thermostat down to the degree (from 60°F to 90°F). It then automatically cycles on and off to maintain the selected temp. Overheat protection, automatic shutoff and a cool-touch exterior also mean you won’t be sacrificing safety for affordability.

You can confidently rely on the information presented in this article, as it stems from my extensive experience in the home improvement, DIY and appliance spaces. With more than five years spent as a residential and commercial carpenter in NYC, specializing in custom furniture construction and installation, I bring a wealth of real-world expertise and hands-on training to the table. As a freelance writer, I leverage my in-depth knowledge to craft thorough product reviews, insightful buying guides and practical how-to articles for Family Handyman. My work has also been featured in reputable outlets, such as CNN Underscored, Business Insider and Popular Mechanics.
For this article, I consulted with HVAC technician and plumbing expert, Josh Mitchell, who founded Air Conditioner Lab when he saw how confusing it was to shop for these common home appliances. He then began experimenting with ACs, heaters, air purifiers, dehumidifiers and humidifiers to find the best options to help people solve their HVAC problems. Mitchell also started other home improvement sites, the Plumbing Lab and Paint Sprayer Judge.
I also got advice from Brad Roberson, who has almost 20 years of experience and is the president of Aire Serv, a Neighborly company that provides HVAC services to residential and commercial clients. Caitlyn Fitzpatrick, an editor and writer since 2014 and a content strategist in the commerce journalism word since 2017, helped update this piece.

The three general types of bathroom heaters are portable, wall-mounted and ceiling-mounted models. Portable heaters offer flexibility and can easily be moved to different locations. Wall-mounted heaters are compact, quickly warm up small spaces and are typically installed high on the wall to avoid water exposure. Ceiling-mounted heaters are popular for their powerful output and discrete design—and because they don’t take up any valuable floor space.
According to Roberson, it’s best if your HVAC system vents to the bathroom. However, electric wall heaters or radiant heaters are practical alternatives. “These heaters are compact, provide quick warmth and are designed for smaller spaces like bathrooms,” he says. Additionally, they’re often equipped with safety features like overheat protection, making them a smart pick for powder rooms.
Roberson says infrared heaters are an efficient and cost-effective choice. “Infrared heaters directly warm objects and people in the room, providing targeted heat,” he explains. Mitchell agrees, noting that these heaters provide immediate warmth, which is beneficial in a typically cold, tiled room. “It’s also more energy efficient, as it doesn’t heat the air, which can quickly escape in small, often ventilated spaces,” he says.
Whenever you have a heater, you have a potential fire hazard, as you never know when it could overheat. It’s best to turn off a bathroom heater before going to sleep.
