Getting Your Bathroom Heater Wattage Right
Nobody likes that shock of stepping out of a warm shower and hitting a freezing cold bathroom floor. But if you pick the wrong heater, you’re stuck with one of two problems: you’re either burning money on a massive unit you don’t need, or you’re still shivering because the heat just isn’t reaching you. We stick with short-wave infrared lamps for this. Why? Because they don’t waste time trying to heat up all the air in the room. They go straight for you and the surfaces around you. It’s an instant warmth.
Finding the Right Power
The amount of power you need mostly comes down to how much space you’re trying to warm up. If you’ve got a tiny powder room (under 4m²), a single lamp between 400W and 600W usually does the trick. It’s simple and effective. For those medium-sized bathrooms (around 5-8m²), you’ll want to bump that up to somewhere between 800W and 1200W. Now, if you’re dealing with a big master bath (over 10m²), don’t just buy one giant 2000W monster. Trust me on this. It’s much better to use three 600W lamps spread out across the ceiling. That way, you get a nice, even glow of heat instead of one scorching “hot spot” right under the light while the rest of the room stays chilly.
A Few Things to Watch Out For
Here’s the thing about high-wattage lamps: they’re thirsty for power. You’ve got to check your wiring. If you plug a 2000W heater into the same circuit as your hairdryer, you’re going to trip the breaker. It’s a pain. If you’re going for a high-power setup, just run a dedicated line to it. Then there’s the water. Since this is a bathroom, you need lamps sealed in quartz envelopes with the right IP rating. That extra layer of glass is great for safety, but it does block a tiny bit of the heat. To make up for that, we usually kick the wattage up by about 10%.
How to Set It Up
Placement is everything. Aim for a height of about 2.2 to 2.5 meters. If you mount them too low, it’s too intense—you might actually burn yourself. Too high, and the heat dissipates before it even hits your skin. And please, use a timer or a sensor to shut it off after 15 minutes. These things get hot fast. Leaving them on all day is just throwing money away and wearing out the filament for no reason.
