Getting the Right IR Heater for Your Bathroom
Here is the biggest mistake people make when buying an infrared heater: they think “more power equals more comfort.” In reality, buying the biggest lamp you can find is usually a waste of money. It’s all about the fit. If the wattage doesn’t match your room size and ceiling height, you’ll either end up shivering in a cold corner or feeling like you’re standing inside a toaster.
Let’s talk about size
Think about your space. If you’ve just got a tiny powder room (under 4m²), a 400W to 600W shortwave lamp is plenty. In a space that small, anything more powerful will just overheat the room in a few minutes. That forces the heater to click on and off constantly, which wears out the filament and kills the bulb way faster than it should. For those medium-sized bathrooms (5m² to 10m²), you’re looking at something in the 800W to 1200W range. Then you have the big master baths or commercial spaces. For those, don’t just buy one massive lamp. You’ll end up with one scorching “hot spot” right under the bulb while the rest of the room stays freezing. Your best bet? A few 1500W units spread out evenly.
The electrical side of things
One cool thing about shortwave IR lamps is that they heat you, not the air. That’s a lifesaver in a bathroom where steam and drafts usually steal all the warmth the second you turn the heat off. But keep in mind: higher wattage means a heavier pull on your electricity. If you’re putting a 1500W lamp into an old house, double-check your wiring and breakers first. Old wires can struggle with that kind of load, and you don’t want to be tripping your circuit breaker every time you take a shower.
A quick cheat sheet
If you’re staring at a catalog and aren’t sure what to pick, try these baselines: ***Small (1-4m²):**400W-600W. One lamp is all you need. ***Medium (5-10m²):**800W-1200W. Try to aim it right where you step out of the shower. ***Large (10m²+):**1500W+ or a couple of 800W units. Just don’t overdo it. Putting a 2000W lamp in a tiny stall is just throwing money away on your electric bill—and it puts a lot of unnecessary stress on the fixture itself.
