Getting the Heat Right in Your Bathroom
When you’re picking out an infrared heater for the bathroom, the temptation is to just grab the most powerful one on the shelf. But here’s the thing: more power isn’t always better. If you go overboard, you’re just throwing money away on your electric bill and turning your bathroom into a sauna. Go too low? You’re still shivering when you step out of the shower. It’s all about finding that sweet spot where the heat actually fits the room. Finding your number Think about the size of your space. If you’ve got a tiny powder room—something under 3m²—a 250W to 400W lamp does the trick. These are great because they warm you up instantly without having to heat up every single inch of air in the room. For those medium-sized bathrooms (around 3m² to 6m²), you’ll want something in the 600W to 800W range. I usually suggest going with two lamps here. It spreads the warmth around better so you don’t end up with one scorching hot spot and a cold shoulder. If you’re dealing with a massive master bath over 6m², you’re looking at 1000W or more. You might even want to set up a few different heating zones so the whole room feels cozy. The nitty-gritty on water and heat Since this is a bathroom, water is the enemy. These heaters use quartz glass tubes tucked into IPX4 or IPX5 rated housings. Basically, it’s a seal that keeps steam and splashes away from the electrical bits. Without that, you’re looking at a blown fuse or a short circuit, which is a nightmare nobody wants. But be careful with the hardware. A 1000W lamp gets hot at the base. If the housing isn’t built to handle that kind of heat, the plastic can actually warp over time. Always double-check that the fixture can handle the wattage before you crank it up. A pro tip for your wallet If you want to get the most out of your setup, install a tiered switch with low, medium, and high settings. It’s a simple move that makes a huge difference. You can blast it at 800W to get that initial “warm hug” feeling on your skin, then click it down to 250W just to keep the chill away. Your circuit breaker—and your bank account—will thank you.
