Picking the Right Infrared Lamp for Your Bathroom
When you’re picking out an infrared lamp for the bathroom, your first instinct might be to just go for the most powerful one on the shelf. But that’s actually a mistake. It’s more about finding that “sweet spot” where the heat matches the size of your room and the materials you’ve got on the walls. Go too big, and you’re just throwing money away on your electric bill. Go too small, and you’ll still be shivering when you step out of the shower.
Let’s talk about room size
It really comes down to how much space you’re trying to warm up. If you’ve got a tiny powder room—something under 4m²—a 250W to 400W shortwave lamp is usually plenty. Those small spaces hold onto heat really well. But if you’re dealing with a big master bath (think 8m² to 12m²), you’ll want to bump that up to 600W or 800W. Here’s a pro tip: keep an eye on your tiles. Marble, stone, and porcelain act like “cold sinks”—they basically suck the heat right out of the air. If your bathroom is decked out in heavy stone, I’d suggest adding about 15-20% more wattage just to get past that initial chill.
The trick to shortwave heat
The cool thing about shortwave lamps is that they’re instant. They don’t waste time trying to warm up the air; they warm you directly. It feels like standing in a patch of sunlight on a cold day. This is why they’re so great for damp bathrooms where old-school heaters just struggle. But be careful with the power. An 800W lamp is intense. If you mount it too low, it’ll feel like a heat gun hitting you in the face, which isn’t exactly the “relaxing spa vibe” you’re going for. I usually recommend mounting them at least 2.2 meters up. This lets the heat spread out in a nice cone, covering more of the floor without creating those annoying “hot spots.”
Saving a bit of cash
If you want to stop wasting power, don’t just install one massive 1200W beast. Try this instead: put in two 400W lamps on separate switches. That way, you can just turn on the one you actually need depending on where you’re standing. It keeps the bills lower and means your lamps will actually last longer.
