The Immersion bathtub, inspired by traditional timber bathing vessels used in Japan and China, is deeper than a standard tub and occupies a smaller footprint. Similar to an onsen hot spring experience, it offers two posture of bathing: one more upright rather than reclined thanks to a seat realised in iroko wood or Cristalplant® positioned along one of the side; while the added depth allows a full immersion of the entire body for deep relaxation. The bathtub is made in white Cristalplant® biobased or two coloured.
