Black Window Grill Design – 20 x 30 Casement Window for Bathrooms

Add privacy and character to your space with a black window grill design paired with a compact 20 x 30 casement window — a practical and stylish choice for bathrooms where ventilation, light control, and durability are essential. Designed as a retrofit solution, this window suits second-floor bathrooms in Toronto homes.

The black exterior frame gives the facade a crisp, modern look, while the white interior finish keeps the bathroom bright and clean. Decorative 5/8” aluminum grills in a 2×2 pattern add visual interest without blocking natural light. Built with Low-E 180 double-pane glass and argon gas fill, the window improves insulation, reduces condensation, and maintains comfort in moisture-prone environments.
