How to actually pick the right wattage for your bathroom heater
Let’s be honest: there is nothing worse than stepping out of a hot shower into a bathroom that feels like a walk-in freezer. It kills the mood and makes you want to rush back into the water. When you’re picking out those IP65 waterproof infrared lamps, it’s all about balance. If you put a powerhouse lamp in a tiny powder room, you’re going to feel like you’re standing under a heat lamp at a buffet. Too much, too fast. But if you go too small in a big master bath? You’re still shivering. Getting the size right Here is a good rule of thumb. For those tiny bathrooms (under 4m²), a 250W to 400W shortwave lamp usually does the trick. The best part? You don’t have to wait for the whole room to warm up. The heat hits your skin almost instantly. If you’ve got a medium space (4m² to 8m²), you’ll want to bump that up to 600W or 800W. Now, if you’re dealing with a massive luxury bathroom over 10m², don’t just buy one giant heater. That’ll just leave you with “cold spots.” Instead, spread a few 600W units across the ceiling. Just a heads-up: don’t go overboard with the wattage. You don’t want to spike your electric bill or, worse, trip your breakers because the wiring can’t handle the load. The “Waterproof” factor Since we’re talking about bathrooms, waterproof seals are a must. That’s where the IP65 rating comes in. It basically means dust and water sprays won’t mess with the electrical guts of the lamp. But here’s the thing: to keep the water out, these lamps have a layer of glass or polycarbonate. That glass blocks a little bit of the heat. We always keep that in mind when we calculate the wattage, so you actually get the warmth you’re paying for. A few practical tips Shortwave lamps are great because they’re instant. You flip a switch, and you’re warm. The only downside is that the heat can feel a bit “sharp” if it’s too strong. To save some cash on your power bill, I highly recommend wiring these into a timer or a motion sensor. Running an 800W lamp in an empty room is just throwing money away. One last thing: check your ceiling height. You want it between 2.2m and 2.8m. If your ceilings are way higher than that, the heat just drifts away before it ever reaches you.
