How to Actually Pick the Right Infrared Heater for Your Bathroom
Here is the thing about bathroom heaters: more power isn’t always better. If you just buy the biggest, baddest lamp on the shelf, you aren’t necessarily getting a warmer room—you’re probably just wasting money on your electric bill. The trick is to match the heat to the actual size of your space. Finding your sweet spot If you’re dealing with a tiny powder room (anything under 4m²), a 400W to 600W lamp is plenty. It keeps you warm without making the room feel like a sauna. For those medium-sized bathrooms (between 4m² and 8m²), you’ll want to bump it up to 800W or 1000W. But if you have a massive master bath—we’re talking 10m² or more—don’t just buy one giant lamp. Instead, scatter a few 1200W units across the ceiling. It spreads the warmth around so you don’t end up with “cold zones” where you’re still shivering. Putting a 1200W lamp in a tiny stall is a bad move. It’ll eat electricity and likely shut itself off because it overheated. On the flip side, a 400W lamp in a huge room is basically useless; the heat just won’t reach you. How the heat actually works These lamps use short-wave infrared. Instead of trying to warm up all the air in the room (which takes forever), they beam heat directly onto you. It feels like standing in a patch of sunlight on a cold day. Because of that, where you put the lamp matters more than the wattage. Keep an eye on your ceiling height. If your ceilings are higher than 2.5 meters, you’ll need a bit more power to make sure that warmth actually hits the floor. A few warnings before you install Just a heads-up: higher wattage means more stress on your wiring. If you hook up three 1200W lamps to one circuit without checking your breaker, you’re probably going to trip the power. Not a great way to start a morning. Also, these things get hot. Really hot. Make sure there’s plenty of breathing room between the lamp and anything that could scorch, like low-hanging cabinets or trim. Give it some space to breathe, and you’ll be all set.
