Getting the Wattage Right for Your Bathroom Heater

When you’re picking out an infrared heater for the bathroom, the temptation is to just go for the most powerful one on the shelf. But here’s the thing: bigger isn’t always better. If you overdo it, you’re just throwing money away on your electric bill—and you might actually make the room feel stifling. On the flip side, if you go too low, you’ll be standing there shivering while the heat vanishes into thin air. You want that “just right” feeling. Matching the power to your space It mostly comes down to how much room you’re trying to warm up. For a tiny powder room, something in the 400W to 600W range usually does the trick. It’s a small space, so it heats up almost instantly. If you’ve got a standard guest bath, you’re probably looking at 800W to 1200W. Now, if you have a massive master bath with high ceilings, you’ll need 1500W or more to keep things cozy. One thing people often forget: tiles and glass are heat sponges. They suck the warmth right out of the room. If your bathroom is basically a giant glass and porcelain box, you might want to bump up the wattage just to fight that chill. How it actually works The cool part about infrared is that it doesn’t bother warming up the air. It warms you. It’s like standing in a patch of sunlight on a cold day. Because of that, you can often get away with less power than you’d think. To save even more on your bills, I’d suggest pairing the heater with a motion sensor or a simple timer. That way, it’s not running while the room is empty. Just a heads-up: be careful with those high-wattage units in tiny spaces. A 2000W heater in a small stall can feel a bit too intense—almost like a heat lamp at a buffet—if you stand too close. A few tips for the install Where you put the heater matters just as much as the power. Mount it so the heat hits you right in the torso. And for heaven’s sake, don’t put it directly under an AC vent. If you do, the cold air will just blow the heat away before you even feel it. Also, double-check your local voltage. You want a direct match so you don’t have to mess around with bulky transformers that just eat up your efficiency.
