Picking the Right Infrared Heater for Your Bathroom
Here is a common mistake: thinking that the biggest heater is always the best. It isn’t. If you just grab the most powerful lamp on the shelf, you’re probably just throwing money away—and you might actually make your bathroom less comfortable. The trick is matching the wattage to the actual size of your room. Let’s talk size. If you’ve got a tiny bathroom (anything under 4m²), you don’t need a powerhouse. A 250W to 400W lamp is usually plenty. If you go overboard here, the room gets hot way too fast. Your thermostat will start clicking on and off every few seconds to keep up, and that constant cycling is a great way to wear out your relays. For those mid-to-large bathrooms (around 6m² to 10m²), you’ll want to step up to 600W or 800W. Heat escapes faster in bigger rooms, so you need a bit more punch to keep things cozy. Pro tip: instead of one giant, scorching lamp, try splitting the load between two smaller ones. It makes the heat feel more natural and stops those annoying cold spots on the floor. The “Steam” Problem Bathrooms are basically torture chambers for electronics. Between the steam and the occasional splash, most wiring just gives up and rusts. That’s why we use IP65 sealing. It keeps the moisture out of the guts of the heater. You get a replacement that actually lasts, rather than something that burns out the moment the shower gets steamy. A quick warning on your wiring Higher wattage means the room warms up faster. Great, right? Well, just keep an eye on your electrical load. If you’re planning to install a few 800W lamps on one circuit, double-check your wiring gauge. If you overload the circuit, you’ll be tripping breakers or dealing with voltage drops—which actually makes your lamps put out less heat. Just make sure your wiring can handle the peak load. It’s a small detail, but it’s the difference between a warm morning and a tripped fuse.
