The design of the piece has been conceived by Phoenix Design. It sports a sophisticated and ergonomic style with a wide rim which is positioned along one length of the tub. The interior portion of Asymmetric Duo is designed to offer comfort and incorporates a contoured pattern.

The rim of the bath comprises a ledge for mounting tap and shower fittings while also offering storage space for holding bath items, when aligned against the wall. The rim of the piece can also be placed in the room for use as a storage area, while making room for easy tub access.
