Can I Put a Skylight in My Bathroom?
By Regal Glass Group
If your bathroom feels dark, cramped, or just lacks that spa-like feel, you’re probably wondering:
“Can I put a skylight in my bathroom?”
The answer is a solid yes — and it might just be the smartest thing you do for your space.
Skylights in bathrooms are becoming more popular across the UK, especially in modern loft conversions, flat roof extensions, and internal bathrooms with no windows. They provide privacy, natural light, and even help reduce dampness and mould.
At Regal Glass Group, we often recommend our frameless fixed Regal Glass Skylights for bathrooms — especially when paired with good airflow. Here’s why they work so well, plus the best skylight options depending on your space.

💬 FAQ
Yes — as long as it’s designed for moisture-rich environments and installed properly. Modern skylights are built with sealed, thermally efficient glass that can easily handle humidity.
It depends. A vented skylight (manual or electric) can improve airflow. But many customers pair a fixed frameless skylight with an extractor fan — it’s cleaner, easier, and looks sleek.
Absolutely. Our frameless Regal Glass Rooflights are ideal for flat roof bathrooms — offering privacy, daylight, and a modern finish.
Not at all. Because skylights face upward, no one can see in — and you still get natural daylight without needing blinds or frosted windows.
Not if you choose the right glazing. Our Regal Glass Skylights come triple-glazed with low-E coatings to reduce glare and maintain temperature comfort.
