How to Pick the Right Infrared Lamp for Your Bathroom
When you’re picking out an infrared heater for the bathroom, it’s tempting to just grab the one with the biggest number on the box. But trust me, more power isn’t always better. It’s really just about making sure the heat matches the size of your room so you aren’t wasting money on your electric bill—or shivering in the shower. Finding the right fit for your space If you’ve got a tiny bathroom—you know, those little powder rooms under 4m²—stick with something in the 250W to 400W range. If you go too high in a cramped space, you’ll just bake the ceiling while you’re still feeling a chill. Now, if you’re dealing with a big master bath (somewhere between 6m² and 10m²), you’ll want to step it up to 600W or 800W. Here’s the thing: shortwave infrared doesn’t actually heat up the air; it hits your skin directly. It’s an amazing feeling—almost like stepping into sunlight. But if you overdo the wattage, that “warm glow” quickly turns into “too hot to handle.” Dealing with the steam Bathrooms are pretty brutal environments for electronics. All that steam and humidity can kill a heating element fast. That’s why we use quartz glass with special coatings—it keeps the lamps from burning out when things get foggy. You also want to make sure your wiring is rated IPX4 or higher. Basically, you want a tight seal so moisture doesn’t sneak in and short out your terminals. Most of these use R7s or SK15 connectors, which are great because they just pop in and out. But a quick heads-up: check your circuit breaker. If you try to run four 800W lamps on a thin wire, you’re asking for trouble. You’ll see voltage drops, and your filaments will probably pop way sooner than they should. Speed vs. Power High-wattage lamps are fast. Like, “instant heat” fast. The only catch is the initial power spike when you flip the switch. If your electrical panel is already struggling to keep up with the rest of the house, maybe go with a few medium-wattage lamps instead of one giant one. It spreads the heat out more evenly across the room and keeps your breakers from tripping every time you want a warm bathroom.
