How to Pick the Right Infrared Heater for Your Bathroom
Nobody likes stepping out of a hot shower into a freezing bathroom. It’s a shock to the system. But if you just throw the biggest heater you can find into a tiny room, you’re going to end up feeling like you’re in a sauna—and your electric bill will show it. The trick is getting the wattage just right for your space. Since we’re talking about bathrooms, we use shortwave infrared. These aren’t like old-school space heaters that try to warm up all the air in the room. Instead, they heat you and the surfaces around you directly. It’s instant warmth.
Picking Your Wattage
Here is a rough guide to keep you from overdoing it. If you’ve got asmall bathroom (under 4m²), a single 400W to 600W lamp is plenty. Any more than that and the room will heat up way too fast, which is just a waste of power. Formedium spaces (4m² to 8m²), you’re looking at a single 800W to 1200W unit, or maybe two smaller lamps spread out. If you have amassive luxury bath or a huge wet room (over 8m²), you’ll need 1500W or more. In those big spaces, it’s usually better to create a few different “warm zones” rather than one giant heat source. One thing to watch out for:**your ceilings.**If your ceilings are extra high, the heat has further to travel before it hits you. You might need to bump up the wattage just to feel that same cozy warmth at floor level.
The “Waterproof” Part (IP65)
Since this is a bathroom, safety is the big deal. We use IP65-rated gear, which is just a fancy way of saying it’s sealed tight against dust and splashes. We use tempered glass and heavy-duty seals so moisture doesn’t sneak into the electrics. But here’s a pro tip: because these units are sealed tight to keep water out, they can trap heat inside the housing. If you put a massive 1200W lamp into a tiny, cramped waterproof fixture, the socket can get dangerously hot. Just make sure the housing is built to handle the heat without warping.
Getting the Most Bang for Your Buck
To make these really work, put them exactly where you feel the chill most. Right above the shower or the vanity is usually the sweet spot. And please, don’t just leave them running. Toss in a timer or a motion sensor. It keeps the lamps from burning out too quickly and saves you money. It’s a simple tweak, but it makes the whole system last a lot longer.
