How to actually pick the right infrared heat for your bathroom
Here’s a common mistake I see all the time: people think that when it comes to infrared lamps, bigger is always better. They grab the strongest bulb on the shelf and call it a day. But that’s not how it works. If you just throw raw power at a small room, you aren’t making it “cozier”—you’re just wasting electricity and killing your bulbs way faster than you should. It’s all about the balance between the room’s size and the materials inside it. Getting the wattage right You want that feeling of instant warmth on your skin, not a heatwave that makes you sweat. If you’re dealing with a tiny powder room (under 4m²), a 400W to 600W short-wave lamp is usually plenty. These little rooms hold onto heat. If you blast 1000W in there, you’ll end up with “hot spots” that feel aggressive and uncomfortable. Now, for those medium bathrooms (4m² to 8m²), you’ll want to bump it up to 800W or 1200W. Why? Because you’ve got more tiles, mirrors, and porcelain. Those surfaces act like sponges, soaking up that first burst of heat. For the big master baths or commercial spaces, don’t just buy one massive 2000W unit. Trust me on this: go with two 1000W lamps placed at opposite ends. It spreads the warmth around better so you don’t end up with freezing cold corners. The trade-offs you should know about The great thing about infrared is that it heats you, not the air. That’s why it feels so much better in a damp bathroom where a regular heater just struggles to keep up. But there is a catch. Higher wattage means a heavier pull on your electricity. Just double-check that your wiring and breakers can actually handle the load before you flip the switch. Also, keep in mind that while a high-wattage lamp hits you with heat faster, it can wear out the filament if you’re clicking it on and off every five minutes. A simple fix? Toss in a timer or a motion sensor. It keeps the heater from running when nobody’s in the room, which saves you money and keeps your bulbs lasting much longer.
