How to actually get the heat right in your bathroom

If you’ve ever stepped out of a shower into a freezing bathroom, you know the struggle. To fix it, we use short-wave infrared lamps. Here is the secret: these don’t bother heating up the air. They go straight for you and the surfaces around you. It’s way more efficient because you aren’t wasting energy trying to warm up a room full of empty space.

Getting the wattage right

You can’t just throw a random heater in there and hope for the best. Take a tiny powder room (under 4m²). A single 250W to 400W lamp is plenty. If you put a 1000W beast in a space that small, you’ll be sweating in seconds. Plus, the heater will keep clicking on and off, which just kills the relays faster. For those medium-sized bathrooms (5-10m²), I usually go with two lamps totaling around 800W to 1200W. And for the big master baths? You’ll want a few different zones. It’s much better to spread 2000W across three or four smaller lamps. If you just use one massive heat source, you end up with one “hot spot” while the other side of the room stays ice cold. Nobody wants that.
