How to Pick the Right Power for Your Bathroom Infrared Heater
Let’s be honest: nobody likes stepping out of a warm shower into a freezing cold bathroom. It’s the worst part of the morning. If you’re looking at ceiling-mounted infrared lamps, the first thing you’ll notice is the wattage. It can be confusing, but here is the secret: these aren’t like old-school space heaters. They don’t waste time trying to heat up all the air in the room. Instead, they beam heat directly onto you. It feels like stepping into a patch of sunlight on a spring day. Getting the wattage right You can’t just grab the most powerful lamp on the shelf and call it a day. If you’re dealing with a tiny powder room (under 4m²), a 400W to 600W lamp is plenty. Go any higher in a space that small and you’ll basically be roasting yourself—not to mention wasting money on your electric bill. For your average-sized bathroom (around 5-8m²), you’re looking at 800W to 1200W. If you’ve got a massive master bath over 10m², you’ll probably want a couple of lamps or one heavy-hitter over 1500W to make sure you aren’t left shivering in the corners. The “Hot Spot” Problem Here is something the brochures won’t tell you. High wattage means more heat, but it also means the heat is more concentrated. If you put a 1500W lamp in a room with low ceilings (anything under 2.4 meters), you’re going to create a “hot spot.” It’ll feel great for a second, then it’ll feel like you’re standing under a heat lamp at a buffet. If your ceilings are low, stick to lower-wattage lamps and spread them out. It keeps the warmth gentle and even. A few tips for the install Before you start wiring, double-check your circuits. These lamps pull a decent amount of power, so make sure your wiring can handle the load. You don’t want any voltage drops or tripped breakers halfway through your morning routine. Also, notice that these lamps use quartz glass. That’s a good thing—it means the steam and moisture from your shower won’t eat away at the filament. One last thing: placement is everything. Short-wave infrared heat has a very sharp cutoff. The moment you step out of the beam, the heat vanishes. Don’t just center the lamp in the middle of the room for symmetry. Put it exactly where you’ll actually be standing—usually right by the shower or the vanity. That’s where you’ll actually feel the magic.
