How to Pick the Right Infrared Heater for Your Bathroom
Here is the first thing you need to know: bigger isn’t always better. You might think grabbing the highest wattage lamp is the way to go, but that’s a mistake. If you put a monster heater in a tiny powder room, you’re just wasting electricity and making the room feel like a sauna. On the flip side, a weak lamp in a huge master bath is basically useless. You’ll be standing there shivering, wondering why you even bought the thing. It’s all about the size of the space.
Finding Your Number
If you’re dealing with a small powder room—anything under 4 square meters—you can usually get away with a 400W to 600W lamp. It’s enough to get you warm the second you step inside without the thermostat constantly clicking on and off. For those medium-sized bathrooms (around 4 to 8 square meters), you’ll want something in the 800W to 1200W range. But here is a pro tip: don’t just buy one giant lamp. I’d suggest splitting that power across two smaller units. It spreads the heat around much better, so you don’t have one “hot spot” and one “cold spot” in the room. If you have a massive suite over 10 square meters, you’re looking at 1500W or more. At that point, you might even want to set up different heating zones.
The Trade-offs
Higher wattage means the heat hits you faster. A 1200W lamp is almost instant. It feels great, but keep an eye on your electrical panel. You don’t want to be the person who trips the circuit breaker right in the middle of a morning shower because the amp draw was too high. The cool thing about short-wave infrared is that it warms you, not the air. That’s why it works so well even if your bathroom is a bit drafty. Just be careful not to overdo it in a tight space, or the radiant heat can start to feel a bit oppressive.
Making it Work
To actually feel the benefit, placement is everything. You want the lamp mounted where the heat beam actually hits you while you’re standing. Aim for a ceiling height between 2.1 and 2.4 meters for the best results. And please, for the love of your electric bill, use a timer or a motion sensor. There is no point in heating an empty room. It’s the easiest way to keep the place cozy without throwing money away.
