How to actually size your bathroom heater without wasting money
If you’re picking out heating for a bathroom, you’ve probably seen “IP66” all over the spec sheets. Basically, that’s just a fancy way of saying the guts of the heater are sealed tight so steam and dust don’t fry the electronics. It’s a must-have. But the part where people usually mess up is the wattage. Get it wrong, and you’re either shivering in a cold room or paying for electricity you aren’t even feeling.
Picking the right power
Here is the thing about infrared: it doesn’t bother heating the air. It goes straight for the surfaces—and you. For a tiny powder room, a 400W to 600W lamp usually does the trick. It creates a nice little pocket of warmth right where you need it. But if you’re dealing with a big master bath, you’ll want to jump up to 800W or 1200W. Actually, a pro tip? Instead of one massive, scorching lamp, try a few smaller ones. It stops those annoying “hot spots” where one part of your shoulder is roasting while your toes are freezing. Just keep an eye on your wiring. High-wattage lamps kick in fast, but they pull a lot of current. You don’t want to find out the hard way that your circuit breaker can’t handle the load.
The ceiling trap
Since these units are sealed with quartz glass and heavy-duty gaskets to keep the moisture out, the heat stays really concentrated. But height matters. A lot. If you mount a 1200W lamp at 2.2 meters, it feels great. Move it up to 3 meters? You’re going to lose that “instant warmth” feeling. You’ll be burning power, but the heat will dissipate before it ever reaches you.
Making it work in real life
Don’t just flip a switch and leave it. A 1000W lamp running in an empty room is just throwing money out the window. Hook them up to a timer or a motion sensor. That way, the room is cozy the second you walk in, and it shuts off the moment you leave. Plus, make sure your ventilation fan is working. The IP66 shell protects the heater from the steam, but you still want that humidity out of the room so your mirrors don’t stay fogged up for an hour.
