How to Pick the Right Infrared Heater for Your Bathroom
Picking a ceiling heater isn’t about just grabbing the most powerful one on the shelf. I’ve seen people do that, and it usually ends in a disaster—mostly because they end up with a bathroom that feels like a sauna in one spot and a freezer in the other. It’s all about balance.
Getting the Power Right
Think about the size of your room. If you’re dealing with a tiny powder room (under 4m²), you probably only need 400W to 600W to keep things cozy. But if you’ve got a big master bath (somewhere between 8m² and 12m²), you’re looking at 1200W to 2000W. Here’s the thing: wattage is basically your “warm-up speed.” If you go too low, the heater just runs and runs. It never actually reaches the temperature you want, which is a great way to kill the heating element early and watch your electric bill skyrocket.
Where to Put Them (and Why it Matters)
Infrared is different from a standard space heater. It doesn’t warm up the air; it warms up you. It’s that instant, sun-on-your-skin feeling. If you have a larger room, don’t just put one massive, scorching lamp in the middle. That creates “hot pockets.” You’ll be roasting under the lamp, but the second you step two feet to the left to reach your towel, you’ll shiver. Instead, spread the love. Use a few smaller lamps across the ceiling. It makes the heat feel even and natural, rather than like you’re standing under a heat lamp at a buffet.
A Quick Warning on Wiring
Before you go big on wattage, please check your wiring. High-wattage lamps pull a lot of current. If you try to push 2000W through thin, old wires, you’ll get a voltage drop. The funny thing is, your meter will show you’re drawing all that power, but you won’t actually feel the heat. Plus, overheating your junction boxes is a problem nobody wants. Just make sure your wire gauge can handle the load. It’s a boring detail, but it’s the difference between a warm bathroom and a tripped breaker.
