How to Pick the Right Infrared Heater for Your Bathroom
Nobody likes that sudden shock of cold air when you step out of a hot shower. It’s miserable. But here’s the trick: you don’t actually need to heat the whole room to feel warm. That’s why we use shortwave infrared. Instead of trying to warm up the air—which just gets sucked out by your ventilation fan anyway—these heaters beam warmth directly onto you. It feels like standing in a patch of sunlight.
Getting the Wattage Right
Most people just grab a 1500W ceiling unit because it’s the standard. For a medium-sized bathroom, that works great. But if you’re dealing with a tiny powder room, 1500W is just too much. It’s overkill. You’ll hit your target temperature in seconds, and your thermostat will spend the whole time clicking on and off. That’s a great way to burn out your relays. In those tight spaces, stick with 600W or 800W. It’s a much gentler heat. Then you have the big master baths. One lamp isn’t going to cut it there. You’ll end up with “cold spots” where you’re shivering in one corner and roasting in another. To keep things even, we usually space 1500W lamps about 2 meters apart. That way, the warmth follows you across the floor.
The Nitty-Gritty Stuff
Here is something to keep in mind: more wattage means more power draw. If you go with the heavy-duty lamps, make sure your wiring can actually handle it. If the wires are too thin, you’ll get a voltage drop, and your lamp won’t even reach its full temperature. It’s frustrating to buy a powerful heater only to have it underperform because of the cables in the wall. Also, a quick tip on placement. These lamps use quartz glass to protect the filament, which is great for handling steam and humidity. But remember, the heat travels in a specific direction. If you mount them too high, the warmth disappears before it ever reaches you. Aim for a height between 2.2 and 2.6 meters. That’s the sweet spot where you actually feel the glow.
