How to pick the right infrared heater for your bathroom (without wasting money)
Most people think that when it comes to heaters, “more power” equals “more comfort.” But that’s not actually how it works. If you go overboard with the wattage, you’re just throwing money away on your electric bill and risking a burnt-out fixture. On the flip side, if you go too small? You’ll be standing there shivering, waiting for a warmth that never quite arrives. It’s all about the size of the room. For a tiny powder room (under 4m²), something in the 400W to 600W range is usually plenty. If you’ve got a mid-sized bathroom (4–8m²), you’re looking at 800W to 1200W. Now, for those big master baths over 10m², here is a pro tip: don’t just buy one massive, monster lamp. It’ll be scorching in one spot and freezing in the other. Instead, grab a few 600W units and spread them out. You’ll get that cozy, even warmth everywhere. The secret sauce here is shortwave infrared. Unlike a standard heater that tries to warm up all the air in the room—which just floats up to the ceiling and disappears—this stuff hits you and your skin directly. It feels like stepping into a patch of sunlight on a cold day. But a quick heads-up on the gear. High-wattage lamps pack a punch, but they put a lot of stress on the glass. That’s why we use halogen-filled tubes. They keep the filament from popping prematurely, so your heater actually lasts. Also, please check your wiring before you start. A 1500W setup pulls a lot more juice than a 400W one. If your circuits aren’t up to the task, you’re going to be tripping breakers all morning. Not a great way to start the day. When you’re installing them, think about where you actually spend your time. Put the heater right where you stand to brush your teeth or step out of the shower. That’s the “sweet spot.” One last thing: distance matters. Infrared loses its magic the further it has to travel. If you’ve got those fancy vaulted ceilings and mount the lamp way up high, you won’t feel a thing. Keep the lamp about 2 to 2.5 meters from the floor. That’s the trick to staying warm without breaking the bank.
