Basalt Mosaics
The deep, matte character of volcanic stone, in mesh-backed mosaic detail. Basalt mosaics in black and gray volcanic stone — hexagon, penny, and waterjet designs — for sleek, contemporary backsplashes, shower floors, and feature accents with understated, modern depth.
Why basalt mosaics
Basalt is a fine-grained volcanic stone with a soft, matte, charcoal-to-gray tone and a remarkably even, contemporary look — quietly sophisticated rather than flashy. In mosaic form it brings sleek, modern depth, and the many grout lines add slip resistance that makes smaller formats ideal for shower floors. From classic hexagon and penny round to striking waterjet blends pairing basalt with bright Thassos, these mosaics deliver understated, architectural style. Mesh-backed for fast, aligned installation.

Care & coverage: Basalt is a natural volcanic stone and porous — seal it, clean only with pH-neutral products, and avoid acidic cleaners. For the bright Thassos waterjet blend, set with white thinset so the bonding layer doesn't show through. Tone varies naturally from sheet to sheet; order a sample and blend sheets from multiple boxes. Mosaics are sold by the sheet, so confirm coverage.
