Picking the Right IR Heater for Your Bathroom
Here’s a secret: you don’t actually want the most powerful heater on the market. If you go overboard, you’re just throwing money away on your electric bill. The trick is finding that “sweet spot” where the room feels cozy, but you aren’t baking yourself alive.
Finding Your Fit
If you’ve got a tiny powder room (anything under 4m²), a 400W to 600W shortwave lamp is plenty. These things are great because they heat you up instantly, rather than trying to warm up every single molecule of air in the room. For those mid-sized bathrooms—around 4m² to 8m²—you’ll want something in the 800W to 1200W range. If you go too low here, the warmth just vanishes before it even reaches you. But if you’re dealing with a massive master bath (over 10m²), don’t just buy one giant 1200W monster. Trust me on this: get two 600W lamps instead. It spreads the heat around. Otherwise, you’ll end up with one scorching “hot zone” right under the lamp and freezing toes everywhere else.
Watch Your Height
Wattage is one thing, but where you hang the lamp is where people usually mess up. A 1000W lamp feels great when it’s mounted at 2.1 meters. It’s a nice, steady glow. But if you drop that same lamp down to 1.8 meters? Suddenly it’s way too intense. It’s the difference between a warm hug and a heat lamp at a buffet.
Saving Some Cash
Since shortwave IR lamps hit full temperature in seconds, there’s no reason to leave them running. I’d suggest wiring them into a motion sensor or a simple timer. Why pay to heat a room for 30 minutes when you’re only in there for five? It’s just a waste. One last thing—keep an eye on your breakers. Higher wattage means more pull from your electrical panel. Just make sure your wiring can handle the load so you don’t end up in the dark right in the middle of a winter shower.
