Stop Guessing Your Bathroom Heater Wattage

I see it all the time. Someone buys a generic heater, throws it on the wall, and hopes for the best. But here’s the thing: if you don’t actually look at the size of your room, you’re just throwing money away. When you’re using infrared (IR) towel rails, you aren’t trying to warm up the air in the room. You’re just warming up the towel. It’s direct. It’s fast.

Picking the right power for your space

You’ve got to match the wattage to the size of the room and how well it’s insulated. If you’re working with a tiny powder room (under 4m²), a 200W to 400W lamp usually does the trick. If you go overboard here, you’re just wasting electricity and risking a wall that feels way too hot to the touch. For those mid-sized bathrooms (5m² to 10m²), you’ll want something between 600W and 1000W. My advice? Split that power across two lamps. It makes the heat feel more even across the whole rail. Then you have the big master baths—anything over 12m². You’re looking at 1200W or more, or maybe a few different heating zones. If you go too low here, the lamp just runs at full blast forever without ever actually getting the towels hot. That’s a great way to burn out your filament way sooner than it should.
