How to pick the right wattage for your bathroom heater
When you’re picking out an infrared heater for the bathroom, your first instinct might be to just grab the most powerful one on the shelf. But here’s the thing: more power doesn’t always mean more comfort. It’s really just about finding the right balance for the size of your room so you aren’t wasting money or dealing with weird cold spots. Matching the power to the room If you’ve got a tiny powder room—something under 4 square meters—you don’t need a beast of a machine. A small lamp between 400W and 600W usually does the trick. If you go overboard with the wattage in a small space, the room hits its temperature limit way too fast. The thermostat will just keep clicking on and off every few seconds. It’s annoying, and honestly, it wears out the internal parts much faster than it should. For those mid-to-large bathrooms (around 6 to 10 square meters), you’ll want to step up to 800W or 1200W. Since the heat has further to travel, I usually suggest splitting the load. Instead of one giant, scorching heater, try two smaller ones. It makes the warmth feel more even across the whole floor. The trick to placement These heaters work differently than the old-school ones. They don’t just warm up the air; they send out shortwave radiation that hits you and the walls directly. It’s that instant, cozy feeling the second you step in. Because of that, where you put the lamp is everything. If you mount it too high, you lose that immediate “hit” of warmth. Try angling them at about 45 degrees toward where you actually stand. That’s how you get the most out of the radiant heat. Watch your electrics High-wattage lamps feel great, but they’re hungry for power. Before you install a massive 1500W setup, take a quick look at your circuit breaker and your wiring. If your wires are too thin for the load, you’ll get a voltage drop. In plain English? Your lamp won’t actually reach the temperature it’s supposed to, and you’re paying for power you aren’t even feeling. Stick to the wattage that fits your square footage. Overdoing it won’t make the room feel any warmer—it’ll just inflate your electric bill and put a lot of unnecessary stress on your electrical panel.
