Getting the Heat Right in Your Bathroom

Picking out infrared lamps for your bathroom isn’t just about grabbing a bulb and hoping for the best. It’s about making sure you actually feel warm without turning your bathroom into a sauna. Since bathrooms get steamy, we build our lamps with an IPX5 rating. In plain English? They can handle water splashes and humidity without blowing a fuse or shorting out.

Finding the Sweet Spot for Power

You want to hit that perfect temperature without throwing money away on your electric bill. If you’re dealing with a tiny powder room (under 4m²), a single 250W to 400W lamp is usually plenty. Go any higher in a space that small and you’ll just overheat the room. It’s overkill. For those big master baths (around 8m² to 12m²), you’ll need a few more. I’d suggest spreading the load across three or four 500W units. This keeps the heat even. Nobody likes that weird feeling of being scorched on one shoulder while their toes are still freezing.
