How to pick the right infrared heater for your bathroom
Picking a heater for your bathroom isn’t about guessing or hoping for the best. If you go too low on the wattage, you’re left with a damp, chilly room. Go too high, and you’re basically paying to bake your towels while wasting a ton of electricity.
Finding your sweet spot
It really comes down to how much space you’re dealing with and what your floors are made of. If you’ve just got a tiny powder room (under 4m²), a 400W to 600W short-wave lamp usually does the trick. It hits you with that instant warmth the second you step in. For mid-sized bathrooms (4-8m²), you’ll want something in the 800W to 1200W range. Why? Because tile and stone floors are heat sponges—they soak up the warmth, so you need a bit more muscle to fight that chill. Then you’ve got the big luxury baths (10m²+). For these, a single unit might not cut it. You’re looking at 1500W+ or maybe a couple of smaller units spread out to keep the whole room feeling cozy.
It’s about where you put it
Here’s the thing about infrared: it doesn’t actually heat the air. It heats you and whatever else it’s pointing at. That’s why where you mount the thing is actually more important than the raw power. Try angling it at 45 degrees. That way, the heat hits both you and the floor at the same time. And since we use quartz glass, these things warm up in seconds. No waiting around for a “pre-heat” cycle. You flip the switch, and you feel it. Immediately.
A quick warning on your wiring
More power is great, but it puts more stress on your electrical panel. Just a heads-up: if you plug a 1500W heater into the same circuit as your hair dryer, you’re probably going to trip the breaker. It’s a pain. If you’re going for a high-wattage setup, it’s worth having a dedicated line installed. One last tip. Look for the coldest spot in your room. If you’ve got a wall that faces the outdoors or your insulation is pretty thin, just bump your wattage up by about 20%. It’ll make up for the heat leaking out.
