We hand-selected volcanic slate from England's Lake District, sourcing unique pieces of 300 million-year-old stone. Originally rough in texture, honed slate undergoes a grinding and polishing process for a smooth finish. Our designers created this look in a neutral tone to allow the linear markings and fractured features to shine through. Add history to your project, without the maintenance, with our Honed Oyster Slate.

Available in large format 24" x 12" tiles, Portland Stone features waterproof K-Core® technology for a floating installation over most existing hard floors.

Each box contains 16 tiles.

This color is also available in a 12" x 18"
