Custom Bespoke Stone Baths
Every stone bath we build is entirely bespoke — designed around your bathroom, your dimensions, and your choice of material. Our stonemasons fabricate each bath from premium stone slabs, creating clean square-cornered surrounds with undermounted tubs that transform any bathroom into a statement of luxury.

Beautiful Design Styles
No two bathrooms are the same, and no two stone baths we build are alike. Every design is drawn up around your space, your lifestyle, and the materials you fall in love with. Here are three approaches we craft for homeowners across Portsmouth, Hampshire and the surrounding area.
Dramatic Dark Granite Bath
Dark charcoal granite slab panels form a bold, angular bath surround with clean 90-degree edges and a generous flat ledge. Matte black fixtures and moody ambient lighting complete a hotel-suite aesthetic — every panel cut and fitted to your exact bathroom dimensions.
Contemporary Marble Bath
White calacatta marble slabs with soft grey veining wrap this rectangular bath in quiet elegance. The wide stone ledge provides practical space for bathing essentials, while natural daylight brings out the stone's delicate movement — bespoke dimensions ensure a perfect fit for the room.
Warm Natural Stone Spa Bath
Warm beige travertine slab panels bring a calming, spa-like warmth to this bespoke bath surround. A matching stone accent wall ties the scheme together, while the wide flat ledge invites candles, towels, and unhurried relaxation — crafted entirely to the homeowner's specification.

Why Choose a Bespoke Stone Bath?
A stone bath isn’t something you pick off a shelf. Every bathroom has its own dimensions, its own quirks, and its own design personality — so every stone bath we build starts as a blank canvas. You tell us the size, the shape, the material, and the finish. Our stonemasons do the rest.
We fabricate each bath from premium stone slabs, precision-cut and assembled into clean, square-cornered surrounds with the bathtub undermounted beneath a flat stone top panel. The result is a seamless, architectural feature that looks and feels entirely intentional — because it was designed specifically for your space, not mass-produced in a factory.
This is what sets In2stone apart. We’re not reselling someone else’s product. We’re real stonemasons with over 25 years of experience, and we build every bath in our own workshop to your exact requirements. That’s the same approach that’s earned us a 4.9-star reputation across 90+ reviews — and it’s why families trust us with their most important rooms.
Entirely Built to Your Requirements
Your Dimensions, Your Layout
Whether your bathroom calls for a compact alcove bath, a generous island design positioned away from the wall, or an L-shaped surround that follows the contours of the room, we fabricate the stone panels to match. No standard sizes, no awkward gaps, no compromises. Every edge, every corner, every surface is cut to the millimetre.
Your Choice of Stone
The material you choose shapes the entire character of the bath. We guide you through the options in our showroom — where you can see and touch over 500 stone samples — helping you select the material that balances aesthetics, practicality, and maintenance for a wet bathroom environment.
Your Preferred Finish
From a high-gloss polished surface that reflects the light beautifully to a honed matte finish that feels soft and contemporary, the choice is yours. We can also combine finishes across different surfaces — a polished top ledge with honed side panels, for example — to create the exact look and feel you’re after.
Undermounted Tub Integration
The bathtub itself sits beneath the stone surround, mounted from below so that the stone top panel creates a clean, unbroken edge around the bath. This undermount technique gives you those crisp, architectural lines that define a luxury bathroom — and makes cleaning effortless, with no rim or lip where water can pool.
Choosing the Right Material
Granite — Enduring Natural Strength
Granite is extremely hard-wearing and naturally resistant to heat and scratches, making it a superb choice for a bath surround that will see daily use for decades. Each slab carries unique mineral patterns — crystalline flecks, flowing veins, and tonal depth that no engineered material can replicate. When properly sealed, granite handles moisture beautifully and develops a rich character over the years.
Best for: Master bathrooms, traditional and transitional designs, and homeowners who want the depth and authenticity of genuine natural stone.
Quartz — Low Maintenance Luxury
Engineered quartz is non-porous by nature, which means it won’t absorb water or harbour bacteria — ideal qualities for a bathroom environment. Brands like Silestone and Caesarstone offer hundreds of designs, from dramatic marble-effect veining to understated solid tones. Quartz requires no sealing and virtually no maintenance beyond a simple wipe-down.
Best for: Family bathrooms, contemporary designs, and anyone who wants a care-free surface with consistent colour and pattern.
Marble — Timeless Refinement
There is no material quite like real marble for creating a sense of occasion in a bathroom. Its soft, luminous veining and warm tones have been the hallmark of luxury bathing spaces for centuries. Marble does require more care than quartz — periodic sealing and careful cleaning — but many homeowners consider the natural patina that develops over time to be part of the stone’s living beauty.
Best for: Statement bathrooms, boutique hotel-inspired designs, and those who appreciate the character of a material that ages gracefully.
Sintered Stone — Engineered for Moisture
Brands like Dekton and Neolith produce ultra-compact surfaces that are purpose-built for wet environments. Completely non-porous, chemically resistant, and impervious to water absorption, sintered stone is arguably the most practical choice for a bath surround that faces constant humidity and splashing. Available in large formats, it allows us to minimise the number of joins for a cleaner finish.
Best for: High-use family bathrooms, wet room-adjacent baths, and homeowners who want maximum resilience with zero maintenance.
Design Possibilities
Full Surround with Wide Ledge
The most popular configuration. Stone slab panels wrap the entire bath — front, sides, and top — creating a generous flat ledge around the tub. This ledge provides practical space for candles, toiletries, and towels, while the clean geometry of the surround anchors the bath as the room’s centrepiece.
Alcove or Three-Sided Bath
For bathrooms where the bath sits into a recess or against walls, we fabricate stone panels for the exposed front face and top, with the side panels extending to meet the walls. The stone integrates seamlessly with your tiling or wall treatment, creating a built-in look that feels cohesive and considered.
Matching the Full Bathroom
One of the most rewarding aspects of a bespoke stone bath is the ability to match it perfectly with your vanity top, shower tray, or wall panels. Because we fabricate everything in our own workshop — often from the same slab — the colour, veining direction, and finish remain consistent across every surface. This level of visual harmony simply isn’t achievable with off-the-shelf products.
Practical Considerations
Waterproofing and Tanking
Every stone bath surround we build sits on a fully tanked substrate. This waterproof membrane protects against any moisture that might find its way behind or beneath the stone. We work alongside your builder or bathroom installer to ensure the tanking is correctly installed before we fit the stone — this collaboration is critical to a long-lasting result.
Weight and Floor Structure
Natural stone slabs carry meaningful weight, and a full bath surround represents a significant load on your floor structure. During our initial conversation, we discuss your subfloor and assess whether any reinforcement is needed before fabrication begins. In most modern homes the existing floor is more than adequate, but if additional support is required, we’ll advise you clearly and early.
Drainage and Plumbing Access
Even the most beautiful bath needs practical access to plumbing connections. We design discreet access panels into the surround where needed — typically on the front panel — so that your plumber can service the waste and pipework without disturbing the stone. These panels are fabricated from the same material and finished to match, so they’re virtually invisible in daily use.
Sealing and Care
Most stone bath surrounds need nothing more than periodic sealing and a wipe with a damp cloth. For natural stones like granite and marble, we recommend resealing every 12 months with a quality impregnating sealer — a simple 15-minute job. Quartz and sintered stone require no sealing at all.
Our Bespoke Bath Process
From the first conversation to the finished installation, you deal with the same small team of real stonemasons throughout. No handoffs, no subcontractors, no surprises:
- Showroom visit — Browse over 500 stone samples, compare materials and finishes, and discuss your bathroom vision with people who genuinely know stone
- Free quote — Transparent, honest pricing tailored to your exact requirements. The quote is the price — no hidden costs
- Hand templating — Once your bathroom is prepared, we take precision measurements of the bath area, accounting for waste positions, wall angles, and any irregularities
- In-house fabrication — Your stone panels are cut, shaped, and finished in our own workshop by the same team who templated your space
- Expert installation — Fitted, sealed, and finished to the highest standard. We leave your bathroom cleaner than we found it

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. Well done to the entire team - you've exceeded my expectations!"— Ashley ChapmanGoogle
