Round Japanese Soaking Tub – Freestanding Concrete

A deep, round freestanding soaking tub inspired by the Japanese ofuro and handmade in Los Angeles from lightweight concrete. At almost 59 inches across and holding 162 gallons, it is our deepest bathing experience and a centerpiece for primary bathrooms, spa rooms and wellness suites.

In the mountains of Japan, onsen bathhouses are places where water means pleasure as much as cleanliness. We followed the round, staved forms of Hinoki cypress ofuro tubs, then let ours flare gently as it rises.
