Why Bathrooms Need Thoughtful Rooflight Design
Bathrooms tend to be small, enclosed spaces where traditional vertical windows aren’t always practical. Rooflights are an excellent way to:
Increase daylight without sacrificing privacy
Reduce reliance on artificial lighting
Minimise wall condensation and damp
“In 2025, rooflights are becoming essential in contemporary bathroom layouts. Homeowners want more light with less clutter — and skylights are a natural fit.”
— Frances Maynard, Interior Architect, BSc (Hons) Design
Key Features to Look for in a Bathroom Rooflight
✅ 1. Glazing Type
Triple glazing reduces condensation and heat loss
Frosted or obscure glass offers privacy without blinds
Solar-control coatings minimize glare in bright, south-facing bathrooms
✅ 2. Ventilation
Opening models allows steam to escape naturally
Manual or electric options available, depending on ceiling height
Fixed frameless units can be paired with mechanical extractors or passive vents
✅ 3. Frame and Seal Durability
Must resist high humidity and temperature changes
Frameless units from Skylights.co.uk feature UV-stable seals and thermally broken frames
✅ 4. Safety Compliance
- Use laminated/toughened glass that complies with BS EN 12150 and BS EN 14449

FAQs: Choosing Bathroom Rooflights
Yes — but use a fixed model with obscured, toughened glass. Ensure it’s IP-rated or sufficiently sealed from splash zones.
Combine triple glazing, ventilation, and a good extractor fan. Frameless units with low U-values help prevent cold bridging.
Not typically. If the rooflight doesn’t project more than 150mm from the roof plane, it falls under permitted development. Always check locally.
For bathrooms under 10 m², a 600mm x 900mm or 1.0m x 1.2m rooflight is usually sufficient to effectively light the space.
Expert Tips for Installation and Maintenance
Install on a slight slope (even on flat roofs) to promote drainage
Ensure the sealant used is mould-resistant and waterproof
Choose self-cleaning glass to reduce buildup from mineral-rich steam
“We recommend an annual inspection of seals and drainage — especially in wet areas where debris or soap buildup can affect performance.”
— Graham Till, Senior Rooflight Installer
