Stop Guessing Your Bathroom Heater Wattage
When you’re picking out an infrared heater for the bathroom, it’s tempting to just go for the biggest number on the box. More power equals more heat, right? Not exactly. If you overdo it, you’re just throwing money away on your electric bill. If you underdo it, you’re still shivering while you dry off. The trick is matching the power to the actual size of your space. The space vs. power struggle Think about a tiny powder room. It’s a small box. A low-wattage lamp—something around 200W to 400W—is plenty. In a space that small, a massive heater will turn the room into a sauna in about thirty seconds. Nobody wants that. But then you’ve got the master bath. Those are bigger, airier, and way colder. For those, you’ll want 600W or more, or maybe a couple of lamps working together. Here is the part most people miss: if you put a weak heater in a huge room, it’ll work overtime trying to warm you up. It never actually hits that “cozy” temperature, and that constant straining is what burns out the bulb way faster than it should. It’s about where the heat lands Since these are for bathrooms, they’re built with quartz glass and sealed connectors so the steam doesn’t fry the electronics. But here is the cool thing about infrared: it doesn’t actually heat the air. It heats you. It’s like stepping into a patch of sunlight on a winter day. Because of that, where you hang the lamp matters more than how powerful it is. You want that “cone of heat” to land exactly where you stand when you’re stepping out of the shower. The danger of going too big Sure, a 1000W setup gets you warm instantly. But there’s a catch. First, you have to make sure your wiring can actually handle that kind of pull without tripping your breaker. Second, high-wattage lamps can be… aggressive. You end up with these intense “hot spots.” You’ll feel like you’re standing too close to a campfire in one spot, while your toes are still freezing in the corner. Keep it balanced. Match the wattage to your square footage, and you’ll get a nice, even warmth that doesn’t break the bank.
