Onyx Blue Large-Format Porcelain Panels
Onyx Blue large-format porcelain panels feature deep blue tones with dramatic translucent stone movement inspired by natural onyx. The rich color variation and luminous veining create a bold, high-impact surface ideal for statement spaces and luxury interiors.
Designed for showers, feature walls, bathroom walls, and floors, Onyx Blue panels deliver a seamless slab-style appearance with minimal grout lines. The result is a refined, modern surface that balances visual drama with the durability and low maintenance of porcelain.
Due to their size and precision requirements, Onyx Blue porcelain panels must be installed with specialized handling, accurate layout, and proper substrate preparation. Sonoma installs porcelain panels as a complete system — focusing on flatness, alignment, waterproofing, and long-term performance — ensuring the final installation is clean, intentional, and built to last.
