Stone Wet Rooms
A fully stone-clad wet room is the ultimate bathroom luxury — seamless, waterproof, and stunning. Every surface flows as one continuous material, turning an everyday bathroom into a private spa retreat.

Beautiful Design Styles
From dramatic dark enclosures to bright, open-plan sanctuaries, a stone wet room transforms the way you experience your bathroom. Here are three design directions we craft for homeowners across Portsmouth, Hampshire and the surrounding area.
Dramatic Dark Enclosure
Full-height charcoal sintered stone panels wrap every surface, including a built-in bench seat and linear floor drain. Recessed ceiling spotlights create pools of light against the dark veining — moody, immersive, and undeniably luxurious.
Bright Open-Plan Wet Room
White marble-effect porcelain panels flow seamlessly from the dual-head shower zone into the main bathroom space. No step, no threshold — just continuous stone underfoot with a discreet linear drain. Natural daylight reflects off the bright surfaces, creating an airy, hotel-suite atmosphere.
Warm Natural Stone Spa
Warm beige-toned stone panels with organic veining create a relaxed, spa-like retreat. A recessed niche keeps toiletries within reach, while under-vanity LED lighting and a skylight overhead bathe the room in soft, ambient warmth.

Why Choose a Stone Wet Room?
A wet room takes the shower enclosure and removes every boundary. There’s no tray to step over, no screen to squeeze behind, no tiles to grout and re-grout for years to come. Instead, the entire room becomes the shower — a single, seamless space clad in stone from floor to ceiling.
It’s the most complete expression of what stone can do in a bathroom. Where shower walls and vanity tops bring stone to individual surfaces, a wet room brings it to every surface — walls, floor, bench seats, niches, and drainage channels — creating a space that feels cohesive, luxurious, and genuinely different from anything you’ve experienced before.
At In2stone, we’ve been crafting stone surfaces for bathrooms across Portsmouth, Hampshire and the surrounding area for over 25 years. We understand the engineering behind wet rooms as well as the aesthetics — from gradient falls and tanking membranes to material selection and joint placement. The result is a space that’s as watertight as it is beautiful.
The Advantages of a Stone Wet Room
No Grout, No Mould, No Scrubbing
The single biggest frustration with tiled wet rooms is grout maintenance. Hundreds of grout lines in a permanently wet environment become magnets for mould, discolouration, and deterioration. Stone panels eliminate this problem entirely. Two or three large-format slabs cover an area that would need dozens of tiles, with joints so tight they’re virtually invisible. The surface is non-porous, waterproof from day one, and wipes clean in seconds.
A Sense of Space
Without the visual clutter of tile edges and grout lines, a stone wet room feels larger and more open than it actually is. The material flows continuously around corners, up walls, and across the floor — creating a sense of calm and spaciousness that makes even a compact en-suite feel generous.
Uninterrupted Design
Stone panels allow bold materials — dramatic veining, deep marbling, rich colour — to be displayed as they were meant to be seen: in large, sweeping expanses. A calacatta pattern that would be fragmented across tiles instead flows wall to wall, creating a genuine visual statement.
Choosing the Right Material
Sintered Stone — Built for Wet Environments
Brands like Dekton and Neolith produce ultra-compact surfaces engineered to handle constant moisture without flinching. They’re completely non-porous, resistant to chemicals and cleaning products, and available in large formats up to 3200 × 1600mm — enough to cover an entire wall in a single slab.
Best for: Family bathrooms, high-use wet rooms, and anyone who wants maximum durability with zero maintenance.
Porcelain — Design Versatility
Large-format porcelain slabs offer an extraordinary range of designs — from marble reproductions to concrete effects and raw stone textures — at a competitive price point. Thin formats keep weight manageable, while the material itself is completely waterproof and frost-resistant.
Best for: Design-led wet rooms, open-plan bathrooms, and projects where visual variety matters.
Granite — Natural Strength and Character
For homeowners who want authentic natural stone, granite delivers exceptional hardness and water resistance. Each slab is unique, with depth and character that engineered materials can’t replicate. When properly sealed, granite handles wet environments beautifully and develops a subtle patina that many homeowners find even more appealing over time.
Best for: Master bathrooms, traditional designs, and anyone who values the depth of genuine natural stone.
Quartz — Warm and Refined
Non-porous and available in hundreds of designs, quartz brings warmth and elegance to wet room walls and vanity surfaces. Marble-effect quartz from brands like Silestone captures the sophistication of natural marble without the sealing demands. Note that quartz is not recommended for shower floors due to its resin content — we’ll guide you on the best material combinations.
Best for: Wall panels, vanity areas, and homeowners who value a refined aesthetic with minimal upkeep.
Design Possibilities
Fully Clad Enclosures
The defining feature of a stone wet room is total immersion. Walls, floor, bench seats, and even the ceiling soffit can be clad in the same material, creating a seamless enclosure that feels more like a boutique spa than a domestic bathroom.
Walk-In Open Plan
Remove the glass screen entirely and let the wet room flow directly into the main bathroom space. A carefully calculated gradient fall directs water to a linear drain, while the stone floor extends unbroken across both zones. The effect is dramatic, modern, and makes the bathroom feel twice the size.
Built-In Features
Stone wet rooms lend themselves to integrated features that tiles simply can’t deliver. Recessed niches for toiletries carved directly into the stone panels. A floating bench seat for comfort. A full-width linear drain channel that disappears into the floor. These details elevate the room from functional to exceptional.
Book-Matched Walls
For the most dramatic effect, we can book-match adjacent slabs — opening them like the pages of a book so the veining creates a mirrored, symmetrical pattern. In a wet room, where the stone wraps around multiple walls, this technique creates a genuinely breathtaking focal point.
Practical Considerations
Gradient Falls and Drainage
A wet room floor must be precisely graded to direct water towards the drain. We work with your builder or bathroom installer to ensure the correct gradient fall is established before our stone is installed. This is engineering, not guesswork — typically a 1:80 fall across the floor surface.
Tanking and Waterproofing
Behind the stone, a full tanking system ensures the room structure is completely waterproof. This membrane wraps the floor, walls, and any junctions to create a watertight shell. The stone panels provide the beautiful surface; the tanking provides the structural protection underneath.
Panel Joints
Most wet rooms require multiple panels. The joints between them are filled with colour-matched flexible adhesive that’s completely waterproof and doesn’t degrade over time. Unlike grout, this material accommodates the natural movement of the building without cracking. Our stonemasons hand-finish every join to ensure a seamless transition.
Weight and Substrate
Stone panels need a solid, flat substrate — typically cement board or marine-grade plywood. We assess the wall and floor structure during our templating visit and recommend any reinforcement needed. This is one of the advantages of using experienced stonemasons rather than adapting a tiler’s approach — we understand the engineering as well as the aesthetics.

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
