Getting the Heat Right in Your Bathroom
When it comes to infrared heaters, more power isn’t always better. You don’t just grab the biggest lamp on the shelf and hope for the best. It’s really about how much space you’re trying to warm and what your walls are made of. Think about it: bathrooms are full of tiles and glass. Those materials just soak up heat and throw it away. That’s why we stick with short-wave infrared lamps. Instead of trying to warm up all the air in the room, they beam the heat directly onto you. It feels like stepping into a patch of sunlight on a cold morning. Finding your sweet spot If you’ve got a tiny bathroom (under 4m²), a 400W to 600W lamp is usually plenty. It keeps things cozy without turning the room into a sauna. For those mid-sized spaces, maybe 4m² to 8m², you’ll want something in the 800W to 1200W range. And for those big, open master baths? You’re looking at 1500W or more. Here’s the thing: if you put a massive heater in a tiny room, it’ll just click on and off constantly. That’s a great way to burn out your relays. But if you go too small, the lamp will run non-stop and you’ll still be shivering. The nitty-gritty on safety Since this is a bathroom, moisture is the enemy. We use quartz glass because it doesn’t corrode when things get steamy. Plus, the hardware has to be tough enough to handle the lamp expanding and contracting as it heats up, otherwise, those waterproof seals will just crack. One quick warning: high-wattage lamps get seriously hot at the base. You need to make sure your ceiling wiring can actually handle the load. If you plug a 1500W lamp into a circuit meant for 600W, you’re going to trip your breaker—or worse, melt some insulation. Not a great way to start your morning. Saving a bit of cash Sure, higher wattage means you feel the heat faster. But it also means a bigger hit to your electric bill. The easiest way to keep costs down? Toss in a motion sensor or a simple timer. There is nothing more wasteful than a heater blasting away in an empty room. Set it to run only when you’re actually in there, and you’re golden.
