How to actually pick the right infrared heater for your bathroom
Nobody likes that shock of cold air when you step out of the shower. But here’s the thing: getting your bathroom warm isn’t about just buying the biggest, most powerful heater you can find. If you go overboard, you’re just wasting electricity. If you go too small? You’re still shivering. We use short-wave infrared lamps for these ceiling mounts because they’re smart. Instead of trying to heat up all the air in the room—which takes forever—they beam heat directly onto you. It’s like stepping into a patch of sunlight on a winter day.
Finding the right power
Think of wattage as the “strength” of the heat. If you’ve just got a tiny powder room (under 4m²), a single 400W to 600W lamp is usually plenty. You’ll feel the warmth almost instantly. But if you’re dealing with a main bathroom (somewhere between 6m² and 10m²), you’ll probably want a few more lamps or a higher wattage setup to cover the space. And don’t forget to look up. If your ceilings are higher than 2.5 meters, a 400W lamp might struggle. The heat loses its punch before it even reaches you. In those cases, you’ll want to bump up the wattage or add another unit. Just a heads-up: higher wattage means more pull on your electrics. Double-check that your breakers can handle the load so you don’t trip the power the second you flip the switch.
The trade-offs
More lamps mean more stuff on your ceiling, but it keeps things comfortable. The trick is spacing them out. You don’t want “hot spots” where it feels like a sauna in one corner and a freezer in the other. Short-wave lamps are incredibly fast. They’re on, and you’re warm. Period. But if you mount them too low, that instant heat can feel a bit too intense—almost jarring. That’s where the balance comes in. Higher wattage lets you mount the lamps higher up. This spreads the warmth more evenly across the room, though it does require a beefier electrical setup. On the flip side, if you go too low on the wattage, the lamp has to work overtime. It’ll run constantly to try and keep up, which wears out the filament and kills the tube way faster than it should.
