About Hydro Systems OBS5830STO-BIS Ston Obsidian 58" Hydroluxe Solid Surface Freestanding Oval Bathtub

Obsidian is a striking noir volcanic glass that ancient human civilizations chiseled to use as tools, weapons, and ornaments. Hydro Systems references that harmony of function and aesthetic through the thoughtful design of the Obsidian bathtub. The sloped backrest channels ergonomic comfort, while the rim draws the contours and makes for an arresting silhouette. As lustrous as a perfectly tumbled piece of obsidian, this bathtub is crafted from earth’s natural elements and refined to its most beautiful form.
