Getting Your Bathroom Heat Just Right
If you’re putting infrared lamps in a bathroom, the first thing you’ll see is the IP44 rating. That’s just the basics—it keeps the steam and splashes out of the electronics so nothing shorts out. But the part people actually struggle with? Figure out how much power you actually need. Get it wrong, and you’re either shivering in a cold room or paying for electricity you aren’t even using.
Picking the Right Wattage
Here is the thing about infrared: it doesn’t actually “warm up the air.” It warms up whatever it hits—your skin, the tiles, the towel rack. If you’ve got a tiny powder room (under 4m²), a single 250W to 400W lamp is usually plenty. If you go overboard here, you’ll just bake the room, wear out the lamp faster, and waste money. For those mid-sized bathrooms (4m² to 8m²), I’d suggest either one 600W unit or two smaller lamps. And for the big master baths? You can’t just throw one big heater in the middle. You need “zones.” Spreading 800W to 1200W across a few different spots is the only way to make sure you don’t end up with those annoying cold patches.
The Trade-off
It’s tempting to go for the highest wattage possible because it heats up almost instantly. A 1000W lamp is fast. Really fast. But there’s a catch. That much power puts a lot of stress on your wiring and can make the fixture housing get way too hot. Before you go big, just make sure your circuit breaker and wires can actually handle the load without tripping every time you turn the light on.
Some Real-World Advice
I see this all the time: installers cramming high-wattage lamps into tiny spaces. It turns the bathroom into an oven. It’s uncomfortable and, frankly, a bit silly. To make it actually work for you, throw in a timer or a motion sensor. That way, the heat stops the second you leave the room. Also, keep the lamp at least 2.2 meters off the floor. If it’s too low, the heat hits you in one concentrated spot, which can feel a bit intense on the skin. Higher up, the warmth spreads out, giving you that cozy, enveloping feeling instead of a heat lamp at a buffet.
