Getting Your Bathroom Heat Just Right
When you’re picking out an infrared heater for the bathroom, your first instinct might be to go for the biggest, most powerful lamp on the shelf. But here’s the thing: more power isn’t always better. It’s really about finding that sweet spot where the heat matches the size of your room. If you get it wrong, you’re either shivering in a cold shower or paying for electricity you don’t actually need.
Finding the right wattage
If you’ve got a tiny bathroom—maybe something under 4m²—stick with a smaller lamp, probably in the 250W to 400W range. In a tight space, a massive heater is overkill. It’ll get too hot too fast, and the safety cut-offs will keep kicking in, which is just annoying. For those medium or larger bathrooms (around 6m² to 10m²), you can bump it up to 600W or 800W. Think about it like this: if you put a 1000W lamp in a small shower stall, you’ll end up with one blistering “hot spot” while the rest of the room stays chilly. Plus, the lamp will just cycle on and off constantly, which is a waste of energy.
The deal with IP66 ratings
Since we’re talking about bathrooms, moisture is the enemy. That’s why you want an IP66 rating. It basically means the heater is sealed up tight against steam and water sprays, so you don’t have to worry about the internals frying. One little detail to keep in mind: that protective waterproof housing does block a bit of the heat. Some of that infrared energy gets soaked up by the lens before it ever reaches you. Just keep that in mind when you’re deciding on the wattage—you might need a tiny bit more than you think to make up for that loss.
Speed vs. Savings
It comes down to a simple trade-off. High wattage means the room warms up almost instantly. It feels great, but your electricity bill will feel the spike. If you’re looking to save money in the long run, try installing a few lower-wattage lamps across the ceiling instead of one giant one. It spreads the warmth around more evenly and stops a single bulb from burning out because it’s doing all the heavy lifting. And a pro tip? Wire them to separate switches. That way, you only heat the part of the room you’re actually using. Simple, efficient, and way more comfortable.
