Stone and water have always belonged together — one shaped by the other over geological time. Conca makes this relationship explicit: a vessel carved to receive and hold water, finished to a standard that improves with every encounter.

All basins leave the atelier sealed to a hospitality-grade standard. Annual resealing is recommended for long-term performance.
Basins are drilled for standard 40 mm waste fittings. We work with your plumber to specify the optimal drain position.
Overflow channels can be incorporated into the design at the commissioning stage. Advise your plumber of the requirement early.
