Calandra CB039 gives a rectangular stone basin a rhythmic vertical exterior. Rounded ribs repeat across the front face beneath a straight upper edge. The inner basin has defined corners and flat-looking planes, keeping the overall geometry clear.

Golden Blue Onyx is shown in the featured image. Pale blue-green areas meet white and golden lines across the floor and walls. At the front, the repeated ribs break the same markings into narrow sections of light and shadow.

Vertical Rhythm and Stone Colour

Calacatta Oyster marble presents grey-beige veins on a pale ground, and Nero Marquina marble adds fine white lines over black. Notre Dame marble shows larger pale fragments, pink-beige areas and darker connecting veins. Ancient Green marble brings green-white bands, while French Red marble offers a deep red field crossed by finer light lines.

For Calandra, compare the broad interior pattern with its appearance on the ribbed front. A large vein can remain visible across several ribs, while smaller details may become more subtle between them. The actual stone selection determines the placement of those markings on the final basin.

Confirm the full rectangular footprint, basin depth and supporting arrangement before coordinating the surrounding counter. Product drawings and order details should establish waste requirements, tap positioning and the supplied fittings.
