Vessel sinks are popular options, especially in high-end bathroom remodels, and stone can be a striking choice, whether it be marble, granite, onyx, or another. This curvy bathroom sink (available in any of those natural stone materials) will definitely stand out.
The Niao from D’Vontz is a vessel sink that certainly has a distinct design. It’s 8″ tall at its highest point and runs 16.25″ in diameter, so it should fit in most spaces. You can get matching vanity tops from the company, though the real challenge is probably finding faucets and knobs cool enough to go with the sink.
