How to Pick the Right Infrared Heater for Your Bathroom
When you’re picking out an infrared heater, the temptation is to just go for the most powerful one on the shelf. But honestly? That’s usually a mistake. It’s more about finding a balance so you aren’t wasting electricity or, worse, shivering in a room that’s barely lukewarm. Getting the wattage right Think about the size of your space first. If you’ve just got a tiny powder room (under 4m²), a 400W to 600W unit is plenty. Since short-wave radiation hits you directly—rather than trying to warm up all the air in the room—you don’t need a powerhouse. For your average bathroom (between 4m² and 10m²), you’ll want something in the 800W to 1200W range. If you’re dealing with a massive master bath or a big wet room over 10m², you’re looking at 1500W, or maybe a couple of smaller units spread out to cover the area. Just a heads up: if you put a massive heater in a tiny room, you might end up overheating your fixtures or tripping your breakers, especially if your house has older wiring. Why the “IP55” thing actually matters Bathrooms are basically steam rooms. That’s why you need an IP55 rating. In plain English, it means the unit can handle dust and splashes of water coming from any direction. We use sealed gaskets and housings that don’t rust to keep the moisture away from the guts of the machine. If you skip this, the humidity will eat away at the terminals, and your heater will burn out way sooner than it should. The trade-offs Here’s the thing about those high-wattage lamps: they get you warm instantly, but they pull a lot of current. Before you install a 1500W unit, take a look at your wiring. If that same circuit is already powering a water heater or a loud exhaust fan, you might be pushing it. You can either drop down to a lower wattage or have an electrician split the load across two different circuits. I personally love short-wave infrared because it ignores the air and goes straight for your skin. It kills that “cold feet” feeling you get with those old-school convection heaters. One last tip: high-density heat puts a lot of stress on the quartz tube inside the lamp. Just make sure your mounting bracket has a little wiggle room to let the metal expand and contract as it heats up.
