How to Pick the Right Infrared Heater for Your Bathroom
Ever stepped out of a hot shower into a bathroom that feels like a walk-in freezer? It’s the worst. You want that cozy, warm feeling, but getting the wattage right is where most people trip up. If you’re working with a tiny bathroom—maybe around 3 to 5 square meters—keep it simple. A 400W to 600W lamp is usually plenty. Go any higher in a cramped space and you’ll basically be turning your bathroom into a sauna. It’s a waste of power and, frankly, just too hot. Thinking bigger? For those medium-sized bathrooms (6–10m²), you’ll want to bump things up to 800W or 1200W. But here is a pro tip: don’t just slap in one massive 2000W lamp. That creates one scorching hot spot while the rest of the room stays chilly. Instead, try two 600W lamps. It spreads the warmth around so you don’t end up with those annoying “cold corners.” Then you’ve got the big, luxury bathrooms—anything over 12m². For these, you’re looking at 1500W or more. One thing to watch out for here is your ceiling height. If your ceilings are high (over 2.5 meters), a lot of that heat just vanishes into the upper air. You’ll need a bit more power to make sure the warmth actually reaches you. A few things to keep in mind Higher wattage means you aren’t standing around shivering while the heater warms up. A 1200W lamp hits its stride almost instantly. But—and this is a big but—check your wiring first. High-wattage lamps pull a lot of juice. If your circuit can’t handle the amperage, you’re just going to trip the breaker and end up in the dark. I’d suggest going with short-wave infrared. It cuts through steam and moisture way better than long-wave options, which is exactly what you need in a humid bathroom. Just make sure the housing is tough. Bathrooms are brutal on electronics, so you need something that won’t rust or corrode the moment things get steamy. Quick cheat sheet:
- **Small (3-5m²):**Stick with 400W-600W. Keep it efficient.
- **Medium (6-10m²):**Go for 800W-1200W. It’s all about the coverage.
- **Large (12m²+):**1500W+. You need that extra punch to feel the heat.
