How to Actually Size Your Bathroom Infrared Heater

Here is a common mistake: thinking that the biggest wattage equals the best heat. It doesn’t. If you go overboard, you’re just throwing money away on your electric bill. The trick is matching the heat to the actual size of your space.

Getting the wattage right

If you’ve got a tiny bathroom—we’re talking under 4 square meters—you don’t need a powerhouse. A 400W to 600W lamp is usually plenty. Plus, if you put too much power in a small room, the thermostat will just freak out. It’ll kick on, hit the target temp in seconds, and shut off. Over and over. That constant clicking wears out the relays way faster than they should. For those medium or larger bathrooms (around 6–10 square meters), you’ll want to step up to 800W or 1200W. The great thing about shortwave infrared is that it doesn’t waste time heating the air. It goes straight to your skin and the walls. You feel that warmth the second you step in, even if there’s a drafty window nearby.
