How to actually pick the right infrared heater for your bathroom

Nobody likes that sudden shock of cold air the second you step out of a hot shower. It’s the worst. But here’s the thing: solving it isn’t about just buying the biggest, most powerful heater you can find. If you go overkill, you’re basically burning money on your electric bill and turning your bathroom into a sauna. Go too small? You’re still shivering. It’s all about finding that sweet spot based on your room size and how high your ceilings are. Picking your power If you’ve got a tiny powder room or a compact ensuite (we’re talking under 4 square meters), a 250W to 400W lamp usually does the trick. It creates a nice, cozy pocket of warmth right where you need it without trying to heat every single inch of air in the room. For those medium-sized bathrooms—somewhere between 5 and 10 square meters—you’ll want to bump it up to 600W or 800W. Since you’re likely further away from the heater, you need a bit more punch to make sure that warmth actually reaches you before it fades away. Got a massive master bath over 12 square meters? Don’t rely on one giant heater. You’ll end up with one spot that’s scorching and another that’s freezing. Instead, space out a few 800W lamps. It keeps the warmth even and feels much more natural. The ceiling trap Here is where it gets tricky. Your ceiling height totally changes the game. A 600W lamp feels great at 2.4 meters, but if your ceilings are 3 meters high, that same lamp is going to feel way weaker. Infrared heat drops off quickly as it travels. So, if you’ve got high ceilings, you’ll need a higher wattage lamp just to get that same “toasty” feeling on your skin. One last thing—and this is important. More power means more stress on your electrics. If you’re putting a high-power lamp into an old bathroom, please check your wiring first. You don’t want to trip your breakers every time you take a shower because the cables can’t handle the load. Just a quick check of the cable gauge can save you a massive headache later.
