River Stone Sinks collection undeniably is the best selling collection of our products. This soaking tub is made of natural river stone, and is just another version of Flumen bathtub available in the same collection. The difference lies in the edges – they are finished thinly, to create a light and even more natural look. Made of only one piece of stone always. No glue, paint or artificial adhesive are used. Every Freestanding River Rock Bathtub is cut and manually drained by our best craftsmen in Indonesia. We can produce it in the size, shape and shade you desire as we take stone directly from the source. That is the reason why we can guarantee that the client gets the closest boulder bath to the one that is desired!
