Corian® pioneered solid surface and remains the best-known name in the category - for good reason. Its patent expiring is what allowed the wider solid surface market, including Baustone®, to exist at all.
What's changed since is manufacturing, not the underlying principle. Most solid surfaces today - Corian® included - share the same basic composition: a mineral-filled acrylic or polyester resin, cast and cured into a non-porous surface. The differences between brands come down to mineral ratio, resin quality, and finishing process - not a fundamentally different material.
Baustone® is formulated and manufactured to our own specification, developed specifically for the demands of vanity units, basins, and baths rather than adapted from a general-purpose sheet material. It shares the core properties the category is known for - non-porous, stain-resistant, seamless, repairable - and is backed by our own lifetime guarantee on the material.
We don't position Baustone® as "better than Corian®." We position it as ours: developed for BAULANE products, sold direct, without the distributor markup that Corian® based products typically carry by the time they reach a showroom floor.
