1What's the difference between a fan heater and an infrared bathroom heater?
Fan heaters blow warm air quickly, heating the whole room fast but using more energy, while infrared heaters warm objects and people directly with less air movement and lower power consumption. Infrared is better for small bathrooms or targeted warmth, whereas fan heaters work best if you need to heat a larger space rapidly.
2How do I know what wattage I need for my bathroom?
A rule of thumb is 10 watts per square foot of bathroom space — so a 50 sq ft bathroom needs around 500 watts minimum. For faster heating or poorly insulated bathrooms, go for 1500-2000 watts, but check your home's electrical capacity first.
3Should I buy a heater with a thermostat or timer?
A thermostat is worth the extra cost because it maintains a set temperature automatically and prevents overheating, saving energy and money long-term. A timer is helpful if you want the heater running before you shower, but it's less essential than temperature control.
4What safety features should I look for in a bathroom heater?
Look for overheat protection, tip-over shutoff, and waterproof or moisture-resistant housing — essential in a humid bathroom environment. Models with auto shut-off timers and cool-touch exteriors are safer if you have kids or limited bathroom space.
5Is it worth paying more for a wall-mounted heater instead of a portable one?
Wall-mounted heaters save floor space and provide permanent heating, making them ideal if you use the bathroom daily, while portable units offer flexibility if you move or want options. Spend more on wall-mounted only if you have the budget and plan to stay in your home long-term.
