Ishiburo Bathtub
Designer:
Kengo Kuma
The Ishiburo Bathtub, designed by award-winning Japanese architect Kengo Kuma, offers a calming retreat from the outside world. “I aspired to maximise the inherent material quality of stone. Being immersed in warm water contained within stone brings instinctive comfort to human beings,” says Kuma. Ishiburo's distinctive design features a random arrangement of stone batons that come together to form a harmonious, angular composition. Available in various stone finishes.
