CALX Sinks, custom UHPC concrete bathroom sinks with turquoise inlays.

The CALX Sinks

Eureka Springs

2021

The CALX Sinks were crafted for the guest and powder baths in our rammed earth CALX Cabin in Northwest Arkansas. Designed to fit seamlessly against the home’s faceted rammed earth walls, the sinks were cast in Shale and accented with turquoise inlays sourced from Arizona mines.

Each basin was built with a recessed countertop and raised edge - practical details designed to help contain water (especially with three young children in the house). Beyond function, these sinks embody the philosophy that materials should support health as well as beauty. Crafted in UHPC concrete and finished with a healthy, food-safe sealer, they provide safe, durable, and non-toxic surfaces for daily use.

The CALX Sinks are a reminder that the best design starts with respect for the space and the people who will live with it.
