Picking the Right Infrared Heater for Your Bathroom
Getting the wattage right is everything. If you go too small, you’re shivering in a towel. Go too big, and you’ve basically turned your bathroom into a sauna—which sounds great until you’re sweating through your morning routine.
Let’s talk power
You can’t just grab any lamp and hope for the best. If you’ve got a tiny powder room (under 4m²), a 400W to 600W lamp is plenty. It gets the room cozy fast. Trust me, if you overkill it here, you’re just asking to trip a breaker or create those annoying “hot spots” where one side of the room is roasting and the other is freezing. For those medium-sized bathrooms (5-10m²), you’re looking at 800W to 1200W. And for the big master baths or wet rooms over 12m²? You’ll need 1500W or more. But here’s a pro tip: instead of one giant, scorching unit, try two smaller heaters. It spreads the warmth around the floor much better. No more ice-cold tiles under your toes.
Dealing with steam and splashes
Bathrooms are wet. That’s why we use IP55-rated lamps. It basically means the internals are sealed up tight so steam and splashes don’t cause a short circuit. We stick with shortwave infrared because it’s just smarter for this space. Instead of trying to heat up all the air in the room, it warms you and the surfaces you’re touching. You feel that glow the second you step in, even if there’s a draft coming from the window.
A few things to watch out for
High wattage means a heavier pull on your electricity. If you’re putting this into an old house, please check your wiring first. Plugging a 2000W heater into some thin, decades-old cables is a recipe for voltage drops. You might need a dedicated circuit so you don’t fry the lamp’s filament. Oh, and one last thing: keep the heater away from your mirrors. Huge temperature jumps can cause the glass to crack, and that’s a mess nobody wants to clean up.
