How to Actually Pick the Right Power for Your Bathroom Heater
When you’re picking out an infrared heater for the bathroom, your first instinct might be to go for the biggest number on the box. But here’s the thing: more power isn’t always better. It’s really about how much space you’re trying to warm and what your walls are made of. Our waterproof lamps are designed to hit you with that instant, cozy warmth the second you flip the switch. They don’t waste time trying to heat up all the air in the room; they just warm you. Finding the right fit for your space If you’ve got a tiny bathroom—think under 4m²—you don’t need a monster of a heater. A 250W to 400W lamp usually does the trick. If you throw a 600W unit in a closet-sized bathroom, it’ll get way too hot, way too fast. You’ll end up wasting electricity and putting unnecessary stress on the fixture. For those mid-sized bathrooms (around 4m² to 8m²), you’ve got options. A single 600W unit works well, or you can spread the heat around with a dual-lamp setup. Then you have the big bathrooms or those with high, airy ceilings. In those cases, you’ll want 800W or more. Otherwise, the heat might vanish into the rafters before it ever reaches your shoulders. The “Sauna Effect” These heaters use short-wave infrared tech, which basically means the heat travels in a straight line. If you put too much power in a small room, the heat just bounces off the tiles and the ceiling. It creates this oppressive “sauna” feeling that forces your ventilation fan to work overtime. A good rule of thumb? Look at the distance from the lamp to the floor. The closer the lamp is, the less wattage you actually need to feel that same comforting warmth. A few things to keep in mind Making these heaters waterproof adds a bit of a challenge. We use sealed glass and moisture-resistant housings to keep everything safe from steam and splashes. But those seals can trap heat around the base of the lamp. If you jam a high-wattage bulb into a tiny, cramped housing with no airflow, you’re going to burn out the filament a lot faster. Also, double-check your wiring. Higher-power units pull more current, and if your wires can’t handle it, you’ll get a voltage drop. Keep it simple. Match the power to the size of your room, or you’re basically just burning money.
