Getting the Heat Right: Choosing Your Bathroom Infrared Lamp
Here is the thing about infrared heat: it doesn’t actually warm up the air in the room. It goes straight for the surface—meaning you. If you pick a lamp that’s too weak for a room with high ceilings, that heat just vanishes before it ever hits your skin. You’ll be standing there wondering why you’re still shivering.
How much power do you actually need?
It mostly comes down to how much space you’re trying to cover. If you’ve got a tiny powder room, you don’t need much. A single 250W to 400W shortwave lamp does the trick. It gets the space cozy almost instantly without making it feel like a sauna. But once you move into a full-sized bathroom, you’ve got to bump those numbers up to 600W or 800W. And here is a pro tip: don’t just buy one massive, high-wattage lamp. You’ll end up with one scorching “hot spot” right under the light while your toes stay freezing. Instead, go with a few smaller lamps—like three 400W units—spread across the ceiling. It feels much more natural.
The technical side of things
More wattage means you get warm faster. Simple. But it also puts more stress on your electrical system. Check your wiring and breakers before you go overboard. If you hook up four 800W lamps to thin wires, you’ll get voltage drops. That doesn’t just affect the heat; it actually kills the life of your lamps. Now, shortwave lamps are great because they hit you with heat the second you flip the switch. No waiting around. The only downside? The glare can be blinding. To fix that, we use coated quartz glass. It kills the blinding light but lets all that warmth through.
A few tips for installation
Mount your lamps as high as they can go. Just make sure you leave at least 10cm of breathing room between the lamp and anything that could catch fire. And if you’re dealing with an extra-high ceiling—anything over 3 meters—you’ll probably want to add about 20% more wattage. That extra push helps the heat make the trip down to the floor.
