How to pick the right infrared heater for your bathroom
Getting the wattage right on an infrared heater is a bit of a balancing act. You’re dealing with steam, cold tiles, and usually a ceiling that feels just a bit too high. If you go too low on the power, you’ll be shivering in your towel long after you’ve finished your shower. But if you go overboard? You’re just wasting electricity—or worse, you’ll be staring at a tripped circuit breaker in the dark. Finding the sweet spot for your space It really comes down to how much room you’re trying to warm up. For those tiny powder rooms (anything under 4m²), a 400W to 600W heater usually does the trick. If you’ve got a medium-sized bathroom—somewhere between 4m² and 8m²—you’ll probably want something in the 800W to 1200W range. Here’s a pro tip for the big master baths over 10m²: don’t just buy one giant 1200W lamp. It’s a mistake. You’ll end up with one scorching “hot spot” right under the light while the rest of the room stays chilly. Instead, grab two 600W units and spread them out. It feels way more natural. Why the “IP55” thing actually matters You’ll see “IP55” on the box, and you shouldn’t ignore it. In plain English, it means the heater is built to keep dust out and can handle being sprayed with water. Bathrooms are basically steam rooms. Without those seals and the quartz glass, moisture creeps into the wiring and causes corrosion. Trust me, you don’t want that happening above your head while you’re stepping out of the tub. Speed vs. Power The trade-off is simple: more watts means faster heat. A 1200W unit hits you with warmth almost the second you flip the switch. But keep in mind that these high-power lamps create a big “spike” in electricity the moment they start. If your house is a bit older, make sure your wiring and breakers can actually handle that load. The goal isn’t to have the most powerful heater on the market. It’s just to have the one that fits your room. Keep it simple. Don’t over-spec.
