In contrast, the interior basin unfolds with fluid, flared curves that create an enveloping space for the body. The transition between the rigid exterior and soft interior is subtle and gradual, forming a seamless and compact volume that reflects Fukasawa’s design ethos: intuitive, quiet, and refined. Complete with chrome drain, siphon, and overflow, Sabbia is not only a centerpiece of visual serenity but also a practical and timeless addition to contemporary bathroom environments.

Sabbia Stone
The Sabbia bathtub by Naoto Fukasawa for Boffi is a sculptural monobloc piece that explores the interplay between geometric precision and organic softness. Made from matt white Cristalplant®, its form balances strict architectural lines with gentle, flowing contours—offering a bathing experience that is both visually striking and sensorially calming. The outer structure is monolithic and vertically aligned, projecting a sense of grounded stability.
