How to pick the right infrared wattage for your bathroom
Let’s be honest: nobody likes stepping out of a hot shower into a freezing bathroom. It’s a shock to the system. That’s where infrared lamps come in, but if you just grab the strongest one on the shelf, you’re going to have a problem. First things first—since we’re talking about a room full of steam and splashes, make sure your lamp has anIPX5 waterproof rating. It’s the bare minimum. You don’t want to be worrying about short circuits while you’re brushing your teeth.
Getting the power right
You can’t just use one wattage for every room. It doesn’t work that way. If you’ve got a tiny powder room (around 3-5m²), a 250W to 400W lamp is plenty. If you go overkill here, you’ll just end up feeling stifled, and you’ll be throwing money away on your electric bill. For those mid-sized bathrooms (6-10m²), look at 600W to 800W. Now, if you’re dealing with a massive master bath (12m² or more), you’ll need 1000W or more. But here is a pro tip:**don’t put all those watts in one spot.**Split them across a few different lamp heads. Otherwise, you’ll have one scorching hot spot right under the light and the rest of the room will still feel like a refrigerator.
Why it feels different
Here is the thing about shortwave infrared: it doesn’t actually heat the air. It heats you and the things around you. That’s why the wattage matters so much. If you go too low in a big, damp room, the heat just won’t punch through the humidity. You’ll be standing there wondering why you don’t feel anything.
A few things to watch out for
More power means you get warm faster, but it also puts a lot more stress on your wiring. If you’re putting these into an old house with thin, dated wires, jumping straight to a 1200W setup is a great way to trip your breakers. Just double-check what your circuit can actually handle before you go big. And one last thing—look up. If you have really high ceilings, you’re going to lose a lot of that warmth before it hits the floor. In those cases, bump your wattage up by about 15-20% just to make sure it actually feels cozy when you’re standing on the bathmat.
