Getting Your Bathroom Heat Just Right
If you’re looking into infrared heating for your bathroom, the first thing to realize is that this isn’t like a standard space heater. You aren’t just warming up the air and hoping for the best. Instead, the heat travels in a straight line from the lamp directly to you. It’s that instant, cozy feeling the second you step under it. But here’s the trick: you have to get the wattage right. If you put a powerhouse lamp in a tiny powder room, you’re just wasting electricity and wearing out the bulb. On the flip side, a weak lamp in a huge master bath will leave you shivering.
Finding the Sweet Spot
It really comes down to how much floor space you’re working with. For those tiny bathrooms—you know, the ones under 4m²—a single 250W to 400W shortwave lamp does the job perfectly. It’s a small space, so the heat hits you fast. You don’t need anything more. Once you move into a medium-sized room (around 4m² to 8m²), you’ll want to bump that up to 600W or 800W. But for the big bathrooms? Don’t just buy one massive, scorching heater. That usually creates one “hot zone” and leaves the rest of the room freezing. Instead, go with a few lower-wattage lamps spread out. It covers the whole room and feels way more natural.
A Few Things to Keep in Mind
More power isn’t always better. A 1000W lamp is a beast, but it puts a lot of stress on your wiring. You don’t want to be worrying about your circuit breakers tripping or your ceiling fixture getting too hot. Also, think about your ceilings. Shortwave lamps are great for instant heat, but they don’t “throw” the heat very far. If you have massive, vaulted ceilings, you might need a bit more wattage or a reflector that focuses the beam. Otherwise, the heat disappears before it ever reaches your toes. The best bet is to wire everything based on the actual size of the room. Your energy bill will thank you, and your lamps will last a lot longer.
