The Onyx Collection
The Onyx Collection represents the next generation of precision-engineered bathroom solutions. Moving beyond traditional materials, Onyx utilizes advanced composite technology to deliver a "Guaranteed Forever" experience. Each component is digitally calibrated and custom-cast from a high-performance, non-porous resin, ensuring a seamless fit that eliminates the structural vulnerabilities of traditional tile and grout.
From standard-sized shower bases to algorithmically precise custom walk-in systems and vanity tops, the versatility of Onyx is unmatched. With an extensive palette of synthesized colors and textures—ranging from clean, contemporary gloss to rugged, slate-like finishes—Onyx allows for complete design freedom. Whether you are specifying a low-profile, barrier-free entry or a full-height wall kit, The Onyx Collection delivers a technically superior aesthetic that is as easy to install as it is to maintain.
