Frequently asked questions

Corner sink questions before ordering

What dimensions are needed for a corner sink?

Measure both wall runs from the corner, the front projection, overall height and usable bowl dimensions. Also record the finished mounting height and every faucet and drain centerline from fixed edges.

Can a triangle corner sink be made to a custom size?

Many MarbleSinkCo corner designs can be reviewed for project-specific dimensions. Send a plan drawing with both wall lengths, front edge, bowl size and plumbing positions for written feasibility confirmation on Etsy.

Can the faucet be wall-mounted to save space?

Yes, a wall-mounted faucet can preserve deck space when the room plan allows it. Confirm the selected fitting, spout reach, outlet height and supply positions with the local plumber before fabrication.

How is a heavy corner stone sink supported?

The actual wall construction, backing, bracket or frame system, anchors and finished load must be verified by qualified local professionals. Do not rely on drywall alone as structural support.

What is included with a MarbleSinkCo corner sink?

Unless the current Etsy listing says otherwise, the price covers the natural-stone sink only. Faucet, drain, siphon, brackets, furniture, mirror and styling accessories are not included.
