Picking the Right Infrared Heater for Your Bathroom
Here is the secret: you don’t actually want the most powerful heater on the shelf. If you go overboard, you’re just throwing money away on your electric bill—or worse, turning your bathroom into a sauna. It’s all about finding that sweet spot where the wattage matches the size of your room. Getting the wattage right If you’re dealing with a tiny powder room (anything under 4m²), a 400W to 600W shortwave lamp is usually plenty. These rooms are small, so they heat up fast. A lower wattage keeps things cozy without making the air feel stifling after two minutes. For those mid-sized bathrooms (4m² to 8m²), you’ll probably want something in the 800W to 1200W range. Steam changes things here. Damp air handles heat differently than dry air, so you need a bit more kick to feel the warmth. Then you’ve got the big master baths. If you’re over 8m², look at 1500W or more—or even better, a few smaller lamps spread out. If you try to use a weak lamp in a huge room, it’ll run at full blast non-stop. That’s a great way to burn out the filament way sooner than it should. It’s not just about the power Here’s the thing about infrared: it heats stuff, not air. It warms your skin and the tiles, not the empty space. That means where you put the lamp matters way more than the number on the box. If you mount a 1000W lamp too high, the heat dissipates before it even reaches you. Aim for a height where the beam actually hits where you’ll be standing. And a quick heads-up on the electrical side. High wattage pulls more current. Just make sure your wiring can handle the load. If you plug a 2000W setup into thin, old wires, you’ll get a voltage drop. You’ll be paying for the power, but you won’t actually feel the heat. Comfort vs. Intensity High-wattage lamps are intense. They’re amazing for drying off quickly, but they can feel scorching if you’re standing right under them. If you have a larger space, try using two 600W lamps instead of one giant 1200W unit. It spreads the warmth around and gets rid of those annoying “hot spots” where one part of your shoulder is roasting while your toes are still freezing.
