Double Marble Sink & Trough Basins — One Solid Block

A double marble sink carved from one block — no seam down the middle, no joints to fail — is the centerpiece of a serious master bathroom. Marbly Design carves double basins and long trough sinks to your exact vanity width and ships them worldwide, insured and duties paid.

Shared bathrooms work better with two basins; they work beautifully when both are hollowed from the same stone, veining flowing uninterrupted across the full length. Our troughs run up to 200 cm from single blocks.

Specify total width, basin split and faucet drilling; we confirm everything on a technical drawing before carving. Weight guidance and bracket options are included for floating installations.

Frequently Asked Questions

How wide is a double marble sink?

Most of our doubles run 100–160 cm (40–63 in); as custom work we can carve to your exact vanity width, up to ~200 cm from a single block.

Is a one-piece trough better than two separate sinks?

One carved block means no seams to collect grime or fail, uninterrupted veining, and a cleaner installation with fewer drains if you prefer a shared slope.

How heavy are double sinks, and can walls support them?

Doubles typically weigh 40–90 kg; our steel bracket system with stud or masonry fixing is engineered for it, and we provide guidance for your installer.
