All Oceanside Glasstile is made primarily from silica sand, an abundant natural resource, with many colors also containing recycled content that may include pre-consumer, post-industrial, and/or post-consumer recycled bottle glass from curbside recycling programs. All Oceanside Glasstile materials are designed to work together in colors that are consistent across all product lines. You can easily combine liners, decos, and trim from one line with mosaics or field tile from another. The entire Oceanside Glasstile product family integrates to allow unlimited possibilities. Have fun. Be creative.
