Porcelain Slabs, Bespoke Basins, & Complex Tiling: Specialist Design for Luxury Builds
When undertaking a major private new build or extensive architectural refurbishment across Berkshire, Buckinghamshire, Surrey, or Oxfordshire, private clients usually assemble an outstanding main contracting team. Your main builder may be exceptional at structural framing, brickwork, and general fit-out.
However, when a luxury design calls for oversized porcelain slab tiles, decorative mosaics, bespoke slab-fabricated basins, IP-rated backlit onyx niches, or complex steam room and spa environments, standard site teams often reach the limit of their technical capability.
Installing 120cm × 280cm large-format porcelain slabs, mitring integrated stone-look basins, or laying out seamless, multi-room tile grids requires specialised vacuum-handling equipment, substrate movement joint calculations, and millimetre setting-out precision.
At Concept Virtual Design, we bridge this gap. As a specialist architectural design practice and major direct importer, we provide the visual master plans, technical working drawings, and material supply, or deploy our own specialist installation team to execute complex tiling schemes flawlessly.
1. Custom Fabricated Porcelain Basins & Integrated Architecture
One of the ultimate expressions of contemporary bathroom design is material continuity where the wall surface flows seamlessly into the vanity. Rather than specifying off-the-shelf ceramic sinks, Concept designs and supplies custom-fabricated basins crafted directly from the same porcelain tile slabs as your walls and floors.
Using specialist precision cutting and mitred edge-bonding, we create monolithic, floating vanity suites with integrated envelope-sloped bases or hidden slot drains:
- Continuous Vein-Mapping: We match the veining of the wall slab so it cascades down into the custom vanity and basin bowl without interruption.
- Zero-Grout Cleanliness: Because the vanity and basin are fabricated from non-porous porcelain stoneware, the entire unit is completely hygienic, stain-proof, and effortless to clean.
- Bespoke Proportions: Custom sizes accommodate wall-to-wall alcoves, double-suite master vanities, or dramatic cloakroom feature pieces to your exact measurements.
2. IP Rated Backlit Onyx Panels & Feature Shower Niches
Lighting should never be an afterthought in luxury design; it must be built directly into the wet room architecture. To elevate shower enclosures and master suite feature walls, Concept specifies and supplies IP-rated backlit translucent onyx and stone panels.
Integrated directly into recessed shower niches, steam rooms, or vanity backdrops, these waterproof, low-voltage LED panels illuminate the natural veining of the stone from behind:
- Certified Wet Room Safety: High-grade IP-rated LED diffusers ensure complete waterproofing and safety inside direct shower splash zones.
- Atmospheric Scene-Setting: Controlled via smooth dimming channels, backlit onyx creates a soft, ambient glow for evening unwind hours without bright overhead glare.
- Architectural Depth: Pairing dark, rich porcelain slabs with warm, glowing onyx niches adds dramatic visual contrast and tactile depth to the space.
3. Villeroy & Boch Slabs: The 2026 Alternative to Natural Marble
As a major direct importer of Villeroy & Boch tiles, Concept provides private clients with direct access to Europe’s most advanced ceramic engineering.
While natural marble has historically been favoured for high-end builds, its porous nature makes it vulnerable to acid etching, staining from bath oils, and ongoing sealing requirements. In 2026, Villeroy & Boch’s Marble Selection porcelain slab collection offers a superior alternative:
- Authentic Depth & Dramatic Veining: Utilising 6mm slimline OPTIMA formats up to 120cm × 280cm, ranges such as Port St. Laurent, Calacatta Gold, Statuario, and Arabescato Joy capture the plastic depth and natural movement of stone without the fragility.
- VilbostonePlus Surface Shield: Factory-sealed with VilbostonePlus, these porcelain slabs are non-porous, stain-resistant, and chemical-proof and requiring zero sealing or post-treatment over their lifetime.
- Structural Versatility: Lightweight 6mm porcelain stoneware enables seamless wall-to-floor transitions, custom door cladding, bespoke vanity facings, and matching basin fabrications.
4. Whole House Tiling, Staircases, & Spa Environments
Our visual and technical service extends far beyond standard bathroom walls:
- Whole-House Floor Continuity: We design unified floor layouts that flow seamlessly from grand entrance hallways into open-plan living zones, outdoor patio transitions, and principal bedroom suites, establishing a consistent architectural language.
- Bespoke Staircase Tread Design: We design and supply custom-fabricated porcelain stair treads, complete with mitred bullnose edges, slip-resistant step grooves, and integrated LED shadow-gap channels and creating floating, stone-look staircases that match your main floor grids precisely.
- Custom Steam Rooms & Spa Environments: Private wellness suites require intricate technical detailing. We calculate wall falls, substrate waterproofing membranes, steam-bench ergonomics, and ceiling domes to prevent cold condensation drips, ensuring your home spa performs like a five-star hotel https://www.conceptvirtualdesign.com/creating-saunas-and-steam-rooms/
5. Visual Precision & Technical Working Plans
What makes Concept Virtual Design unique is our exceptionally visual and technical process. We do not sell tiles from a catalogue and leave the rest to chance; we design the space digitally before a single tile is ordered.
- Hyper-Photorealistic 4K CGI: We model your exact rooms showing you how tile veining, backlit onyx niches, custom porcelain basins, and lighting washes interact in 4K clarity https://www.conceptvirtualdesign.com/the-future-of-luxury-bathroom-design-our-photorealistic-cgi-focus-explained/
- CAD Setting-Out & M&E Plans: We produce complete setting-out plans for site teams. These detail exact starting points, datum lines, waste outlet positions, shadow-gap details, and tile cuts down to the millimetre. Concept Design
