Step 3 - Finished Custom Concrete Sink – Built to Last

Your custom concrete sink is crafted precisely according to approved drawings, expertly finished, and carefully shipped—built to last and ready to enhance your space for years.



Countertop Integration

Our custom concrete washbasins are designed as one seamless piece, combining the basin and countertop into a single monolithic surface. This makes them perfect for tight spaces—like fitting snugly between two walls—while maintaining a clean, modern look.


Choice of any color

Bespoke washbasins can be made in nearly any color, based on your preferences. We offer two finishing options: the concrete can be pigmented throughout the mix for a rich, durable color, or coated with a specialist concrete paint available in any RAL shade. Both methods ensure a long-lasting, high-quality finish tailored to your design vision.
