Osterley Porcelain Black Square

Inspired by the historic floors of Osterley Park, these tiles capture the essence of time-worn limestone in a practical porcelain format. The black square design echoes the iconic chequerboard pattern, bringing a touch of heritage to modern spaces.

Crafted from porcelain, these tiles offer the authentic look of aged stone with the added benefits of durability and low maintenance. The textured finish enhances their stone effect, creating a surface that is both tactile and visually engaging.

Designed for versatility, they are suitable for both indoor and outdoor use, boasting an R11 slip rating for enhanced safety in wet conditions. Their unrectified edges add to the rustic charm, though care should be taken when mixing colours due to potential size variations.

These tiles are well suited to a variety of settings, from bathrooms and kitchens to hallways and patios. Their classic black hue offers a timeless appeal, effortlessly complementing both traditional and contemporary interiors.

Osterley Porcelain Black Square tiles provide a refined balance between historical inspiration and modern practicality, making them a considered choice for any design scheme.
