How to actually pick the right infrared heater for your bathroom
When you’re picking out an IP65 infrared heater, the instinct is usually to go for the most powerful thing on the shelf. But here’s the thing: more power doesn’t always mean more comfort. If you overdo it, you’re just burning electricity. If you underdo it, you’re left shivering in a cold corner. It’s all about finding that sweet spot. Matching the power to your space If you’ve just got a tiny powder room—you know, those little half-baths under 4m²—a 250W or 400W lamp is plenty. It hits you with immediate warmth without turning the room into a sauna. For a medium-sized bathroom (somewhere between 4m² and 8m²), you’ll want to step up to 600W or 800W. In these rooms, heat has more space to wander off. If you go too low here, the heater will just run non-stop, which wears out the filament way faster than it should. Then you have the big master baths. For anything over 8m², you’re looking at 1000W or more. But a pro tip? Instead of one giant 1200W beast, try two 600W lamps spread apart. It kills those annoying “cold zones” and makes the whole room feel cozy. The deal with IP65 and heat loss Since bathrooms are full of steam and splashes, you need IP65 protection. It’s non-negotiable. We seal these units tight so moisture can’t sneak into the electrical parts. The trade-off is that the sealing adds a bit of a barrier between the heating element and the air. You lose a tiny bit of heat to the housing itself, so keep that in mind when you’re deciding on your wattage. Power vs. Comfort High-wattage lamps have a real “punch” to them. They warm you up fast, which is great, but they can feel a bit intense. If your ceilings are low—under 2.2 meters—that intensity can feel like a glare or even a burning sensation on your skin. If you’re dealing with low ceilings, stick to lower wattage lamps. Just install a few more of them. It spreads the heat out and keeps everything feeling steady and comfortable, rather than overwhelming.
