Custom Marble Sink — Your Dimensions, Carved to Order

Need a sink that fits your space exactly? A custom marble sink from Marbly Design is carved from a single block to your precise width, depth and height — in any of our 13 stones — typically at the same price as standard sizes, with a technical drawing approved by you before a single cut is made.

Renovations rarely come in catalog dimensions, and most homeowners have stopped trying to make them. In the 2025 U.S. Houzz Bathroom Trends Study, a survey of 1,737 U.S. homeowners, 55% specified a fully custom (33%) or semi-custom (22%) vanity rather than a stock unit — and vanity cabinets were the most frequently upgraded cabinetry type at 71%. Awkward alcoves, exact vanity widths and non-standard drain positions are precisely what a made-to-order atelier solves. You send measurements; we send a fixed quote within 24 hours and a drawing within 48 hours of payment.

Every stone on our Materials page is available, and every format: vessel, wall-mount, trough, vanity top, even bathtubs and fireplace surrounds. Production takes 2–3 weeks; insured DDP delivery about one more.

Why a made-to-order stone basin is worth the drawing stage

A custom basin is not just a fit decision — it is a service-life decision. Natural stone is generally credited with a 50–75 year service life and can exceed 100 years, against 30–50 years for porcelain and 25–30 years for engineered quartz (Use Natural Stone, Natural Stone Institute, 2019). The stone itself is dense: ASTM C503, the standard specification for marble dimension stone, caps water absorption at 0.20% by weight, with a minimum density of 2,600 kg/m³ for Class I calcite marble. Getting the dimensions right once therefore matters more than it would with a fixture you expect to replace in a decade.

Shannon Kim, vice-president of Hospitality at Toronto-based Figure3, put the material case to Hotelier Magazine in 2025 this way: “Natural stones, such as marble, travertine and onyx, instantly elevate a space with unique veining and timeless elegance.” Because veining is unique to each block, a custom piece is genuinely one of one — which is also why we confirm matched sets against a single block before quoting.

Frequently Asked Questions

How much extra does a custom size cost?

Usually nothing — custom dimensions typically cost the same or only slightly more than the nearest standard size.

How do I order a custom marble sink?

Use our Custom Order form or WhatsApp: send width x depth x height, stone choice and style. You'll have a fixed quote within 24 hours.

Can I approve the design before you carve?

Always — production starts only after you approve the technical drawing, and we send photos of your finished piece before it ships.

How long will a custom marble sink last?

Natural stone carries a typical 50–75 year service life and often exceeds 100 years (Natural Stone Institute, 2019) — compared with 25–30 years for engineered quartz. Use a pH-neutral cleaner and an impregnating sealer; a honed surface can be re-honed in place rather than replaced.
