Stone Sinks & Basins
An integrated stone sink transforms the ordinary into the extraordinary — a seamless surface with no joints to trap dirt, no edges to catch the eye, just one continuous sweep of natural or engineered stone that flows from worktop into basin.

Beautiful Design Styles
From dramatic undermounted kitchen sinks to sculptural bathroom basins, an integrated stone sink removes visual clutter and creates a surface that's as easy to clean as it is beautiful. Here are three ways our stonemasons bring this to life.
Undermounted Kitchen Sink
A dark granite worktop with an undermounted sink bonded seamlessly beneath — no rim, no lip, just one continuous surface. Crumbs and water sweep straight into the bowl without catching on edges.
Sculpted Bathroom Basin
A marble-effect quartz vanity with an integrated basin carved from the same slab. The veining flows uninterrupted from the flat surface into the bowl, creating a piece that feels more like sculpture than plumbing.
The Invisible Join
The hallmark of true stonemasonship — a close-up showing the perfectly smooth transition from worktop to sink bowl. No visible seam, no trapped dirt, just a continuous curve hand-finished by our team.

Guide
Your Guide to Stone Sinks & Basins
Crafted by Our Stonemasons, Not Bought Off a Shelf
Most stone companies fit a stainless steel or composite sink underneath a worktop and call it a day. We do something different. Our stonemasons fabricate bespoke stone sinks and basins in-house — shaped, carved, and hand-finished by the same team who craft your worktops. The result is a truly integrated piece where worktop and sink are one continuous sweep of stone, with no rim, no silicone seal to discolour, and no joint to harbour dirt.
We’ve already created custom sinks from granite, marble, and quartz, and we regularly work with sintered stone and porcelain for clients who want something more contemporary. If your project calls for a material we haven’t mentioned, talk to Ian — with over 25 years in the stone industry, chances are he’s already worked with it.
Kitchen Sinks — Seamless and Hardwearing
Undermount Stone Sinks
The most requested option. We bond the sink bowl to the underside of the worktop slab, then hand-polish the transition until it’s invisible. Water, crumbs, and spills sweep straight into the bowl without catching on a lip or rim. It’s the detail that makes guests run a finger along the edge and ask, “How is that all one piece?”
Integrated Butler Sinks
For a more traditional kitchen, we carve a deep butler-style basin from a contrasting stone — a crisp white quartz bowl set into a dark granite worktop, for example. The farmhouse warmth of a deep sink, built with the precision of modern stone fabrication.
Drainer Grooves
Instead of a stainless steel draining board, we machine drainage channels directly into the stone beside your sink. These subtle grooves guide water back into the bowl while keeping the entire surface clean and uncluttered — one of those small bespoke details that transforms a kitchen from nice to exceptional.
Bathroom Basins — Sculptural Luxury
Vanity Basins
A stone vanity basin carved from the same slab as the vanity top creates a completely seamless surface. The worktop flows elegantly into the bowl without interruption. Marble-effect quartz works beautifully here — the veining appears to cascade down into the basin, creating something that feels closer to sculpture than plumbing.
Freestanding Vessel Basins
For a bolder statement, we sculpt freestanding vessel basins from solid blocks of stone. Sitting atop a vanity or shelf, these pieces become a dramatic centrepiece in a contemporary bathroom, especially when paired with a wall-mounted tap.
Cloakroom Basins
Even the smallest spaces benefit from stone. A compact stone basin in a cloakroom or WC instantly elevates what’s usually an afterthought, giving visitors an immediate impression of quality and care throughout your home.
Materials We Fabricate Sinks From
Granite — Rugged Natural Beauty
Granite’s exceptional hardness makes it a superb choice for kitchen sinks that take daily punishment. Every slab carries unique natural movement and depth of colour. We’ve fabricated granite sinks in everything from deep blacks to warm speckled tones, sealed to last for decades.
Best for: Busy family kitchens, traditional designs, and anyone who wants a surface that shrugs off hot pans and heavy pots.
Marble — Timeless Elegance
Nothing matches the visual drama of a marble basin. The depth of veining, the warmth of the polished surface, the way light plays across a hand-finished bowl — it’s pure luxury. Marble does ask for a little more care, but many homeowners consider the subtle patina it develops over time to be part of its character.
Best for: Bathroom basins, powder rooms, and design-led spaces where aesthetics take priority.
Quartz — The Practical All-Rounder
Quartz is non-porous, stain-resistant, and available in hundreds of designs. It handles daily use without staining, won’t harbour bacteria, and never needs sealing. For an integrated kitchen sink that needs to survive family life without fuss, quartz is hard to beat. Brands like Silestone and Caesarstone offer stunning marble-look patterns with none of the maintenance.
Best for: Family kitchens, busy bathrooms, and anyone who wants beauty without compromise on upkeep.
Sintered Stone — Ultra-Modern Durability
Sintered stone from brands like Dekton and Neolith is virtually indestructible. It won’t scratch, stain, or discolour — even with bleach, red wine, or extreme heat. For kitchens that see serious use, or commercial settings where durability is non-negotiable, sintered stone is the ultimate material for a bespoke sink.
Best for: Contemporary kitchens, commercial bars, and anyone who wants zero-maintenance performance.
Porcelain — Sleek and Lightweight
Large-format porcelain slabs are increasingly popular for integrated sinks, offering a thinner profile with excellent resistance to scratches and chemicals. The range of finishes — from polished marble-look to raw concrete effect — means porcelain suits almost any design scheme.
Best for: Modern bathrooms, minimalist kitchens, and projects where a slimline aesthetic matters.
How We Make Them
Creating a bespoke stone sink is skilled stonemasonship, and it’s done entirely in our own workshop. The process starts with CNC machining, which cuts the initial bowl shape with sub-millimetre precision. From there, our craftsmen hand-polish the interior through progressively finer grits until the surface is perfectly smooth and consistent with the surrounding worktop.
The join — where the bowl meets the flat surface — is bonded and polished until you genuinely cannot see or feel the transition. This is the kind of work that separates real stonemasons from companies that simply supply slabs. As one of our customers said: “The difference between a stonemason and just suppliers of worktops is huge.”
Practical Details
Waste Fittings and Overflow
Every sink we fabricate accommodates standard waste fittings. We cut the waste outlet precisely to accept your chosen plug assembly. Overflow drainage can be routed through the stone itself, keeping everything hidden and clean.
Tap Holes
We cut tap holes through the worktop with the same CNC precision used for the sink bowl. Whether you want a traditional mixer, a boiling water tap, or a wall-mounted fitting, we’ll cut and finish the aperture to suit.
Weight and Support
Stone sinks add weight, which sometimes requires additional cabinet support underneath. During our hand templating visit, we assess the structure and recommend any reinforcement — no assumptions, no surprises later.

What Our Customers Say
"Excellent Service and Beautiful Results - Highly Recommended! I recently had In2stone install new quartz worktops in my kitchen, and I couldn't be happier with the results. From start to finish, the experience was completely stress-free. The team was not only competitively priced but also incredibly friendly and professional throughout the entire process. They handled everything seamlessly - removing the existing sink, hob, and old laminate worktops before fitting the new quartz surfaces. The finished worktops are absolutely beautiful and have transformed my kitchen into a modern, minimalist space that I love spending time in. The quality of workmanship is outstanding, and the attention to detail really shows. I'm a very satisfied customer and would highly recommend In2stone to anyone considering new worktops.
