Calacatta Picasso Polished Marble Siena Basin 45×55×20 cm

A sink designed for those who like everything in the bathroom to be in its proper place, yet far from ordinary: the Calacatta Picasso Polished Marble Siena Sink. Lilac veins wandering across a glossy white ground, flutes that turn around rounded corners, and a rear deck that carries the faucet directly on it.

Faucet-Ready Rear Deck

Behind the basin of the Siena there is a flat deck, and this deck has 3 faucet holes. The holes are designed for a three-hole countertop faucet: two valves and a spout in the middle. Because the faucet is mounted on the sink itself, there is no need for work such as drilling holes in the countertop or changing plumbing in the wall. Simplifying installation in both new bathrooms and renovation projects, this detail turns the sink and the faucet into a single design whole.

Shining Veins

On the white ground of Calacatta Picasso, purple, lilac and gray veins move with a dynamic, almost painterly motion. The polished surface sharpens these veins and increases the saturation of the colors. As light reflects off the surface, the white ground looks brighter and the lilac tones more vivid. Owing to the nature of natural stone, even when you place two pieces side by side, you see that the veins pass through different places.

The Shape of the Body

The outer surfaces of the sink are worked with vertical flutes, and all its corners are rounded. On polished marble, the ridges of the flutes remain glossy and the gaps shaded; at the corners, these lines of light turn without interruption. Carved from a monolithic block, the body measures 45 × 55 × 20 cm. The basin slopes toward the drain at the center point of the base. The sink takes shape in the hands of stonemasons in Türkiye.

Siena in the Bathroom Setup

Polished Picasso creates a natural focal point in bathrooms that combine classic and modern lines. White or light gray stone countertops, cabinets in walnut or dark lacquered wood, and soft wall colors such as lavender and sage harmonize with this sink. On a three-hole faucet, polished chrome or gold plating reflects the sparkle of the polished surface; classic cross-handle valves add a timeless air.

Care for the Polished Surface

Glossy marble is sensitive to acidic substances: lemon, vinegar, some cosmetics and limescale removers can leave dull spots on the surface. Use a pH-neutral stone cleaner and a microfiber cloth for cleaning. Regularly wiping away water that collects around the valves prevents white deposits from forming around the holes. Cleaning the flutes with a soft brush is sufficient.

Tips for Countertop Planning

The 20 cm height, when added to the countertop level, determines the level at which the sink rim will sit; for comfortable use, you may consider keeping the countertop slightly lower than standard. The 55 cm length leaves a comfortable distance between the faucet on the rear deck and the front edge. It is important that the countertop depth is sufficient to comfortably carry the entire sink and the deck behind it. When you use two Sienas side by side in a double-sink layout, the different vein patterns add a natural richness to the countertop and a symmetrical layout is created.

If you want to bring both function and appearance together in a single piece, Calacatta Picasso Siena meets your expectations with elegance.
