The Kobe tub is part of the "stone likes water" collection designed by Hikaru Mori, this collection originates from the contemporary reinterpretation of the heritage of objects and environments in the Japanese thermal bath tradition: it is made of natural stones, essential shapes and stimulating surfaces conceived to exalt their privileged relationship with water. The "esterna" tub comes with an exterior drain designed to gather the overflow of water.The standard finishes are: "string" or rigato for the exterior and honed for the interior.
