Picking the Right Wattage for Your Bathroom Infrared Heater
Here is the thing about mirror infrared heaters: they don’t actually heat the air in your bathroom. Instead, they send out shortwave radiation that hits you and your towels directly. It’s like stepping into a patch of sunlight on a cold day. But if you pick the wrong wattage, you’re either going to be shivering or feeling like you’re in a sauna. Getting the power right You have to look at the size of your room first. If you’ve got a tiny powder room—something under 4m²—stick with a 250W to 400W lamp. Go any higher and the room will get stuffy way too fast, and your thermostat will just keep clicking off. For a standard medium bathroom (around 5-10m²), 600W to 800W is usually the sweet spot. But if you have a massive master bath, you’re looking at 1000W or more. You might even want a few lamps working together to make sure there aren’t any cold spots. Why the “mirror” part actually matters That mirror backing isn’t just there to look sleek. It’s doing the heavy lifting. It catches the heat that would normally drift up to the ceiling and bounces it right back down toward you. It means you feel warmer on your skin without having to crank up the electricity bill. A few things to watch out for Before you go for the most powerful lamp available, check your wiring. A 1200W lamp puts a lot more stress on your electrical system than a 400W one. If your wiring isn’t up to the task, you’re looking at tripped breakers or worn-out sockets. It’s just not worth the headache. Also, keep in mind that these things are built for speed. They blast you with heat the second you flip the switch, but that warmth disappears just as fast once you turn them off. They aren’t meant to keep the whole room at a steady 22°C all day. If that’s what you’re after, you’ll want to use these alongside a regular heater. Use the infrared lamp for that instant “ahhh” feeling the moment you step out of the shower.
