How to actually pick the right wattage for your bathroom heater

When you’re looking at infrared lamps, it’s tempting to just grab the one with the biggest number on the box. But here’s the thing: more power doesn’t always mean more comfort. It’s really just about making sure the heat fits the size of your room so you aren’t wasting electricity or shivering in a cold corner. Matching the power to your space Most of these bulbs run anywhere from 250W to 1200W. If you’ve got a tiny powder room—something under 4m²—a single 400W to 600W shortwave lamp is plenty. You’ll feel that warmth hit you the second you walk in. But if you’re dealing with a big master bath (8m² or more), one lamp isn’t going to cut it. You’ll want a few of them—maybe three 800W lamps—spread across the ceiling. That way, the heat is everywhere, not just in one hot spot. And a quick heads-up: don’t overdo it. Putting a massive heater in a tiny closet can actually burn the lamp out faster because it just gets too hot. On the flip side, if the lamp is too weak, it has to work overtime just to keep up, which fries the filament. Why shortwave is the way to go These lamps use quartz glass and tungsten to send out shortwave infrared radiation. Now, that sounds technical, but all it means is that the lamp doesn’t bother heating the air. Instead, it warms your skin and the surfaces around you directly. This is a huge win for bathrooms. Since you aren’t heating the air, you don’t end up with that annoying condensation and steam buildup on the mirrors. Plus, it’s fast. Like, really fast. You flip the switch and you’re warm. No waiting around for a bulky oil radiator to finally wake up. A few things to watch for during install Just keep in mind that higher wattage means more stress on your electrical system. If you’re installing 1200W units, take a look at your wiring. If the wires are too thin, they can actually get hot under the load. That leads to voltage drops and kills the life of your lamps. You just want to make sure your circuit can handle the load so you aren’t tripping breakers right in the middle of a freezing January morning.
