IDEAL FOR
Residential Applications:
Transform your home with the dramatic character of Black Riven Slate stone tile flooring. The 100% waterproof construction makes it perfect for hallways and entrances, where the traditional slate aesthetic creates impactful first impressions while handling muddy boots, wet umbrellas, and heavy foot traffic with ease. In boot rooms and utility rooms, the rugged black slate appearance provides practical elegance for hard-working spaces that need to look good while withstanding daily wear. Create stunning bathrooms and wet rooms where the riven slate texture adds natural beauty and spa-like ambience, while the waterproof construction eliminates concerns about moisture damage that would affect natural slate. In kitchens and dining rooms, the deep black tones provide sophisticated grounding for contemporary cabinetry or striking contrast for traditional country kitchens. The dramatic slate aesthetic works beautifully in living rooms for those seeking bold, characterful flooring with natural stone authenticity. Consider Black Riven Slate for conservatories where the stone aesthetic bridges indoor and outdoor spaces, and even home offices requiring professional elegance with earthy, grounding tones. The timeless slate aesthetic suits both traditional country cottages seeking authentic stone flooring and contemporary townhouses embracing industrial-natural design fusion.
Commercial Applications:
Black Riven Slate ST15 excels in commercial environments where authentic stone aesthetics meet budget constraints and performance requirements. Ideal for care homes and assisted living facilities requiring slip-resistant, waterproof flooring with easy maintenance, the riven slate texture provides grip while the black tones hide soiling in high-traffic areas. Perfect for student accommodation and rental properties where durability and style must coexist with budget considerations – slate aesthetics suggest quality without premium pricing. Excellent for community living schemes and traditional housebuilds requiring specification flooring that delivers natural stone authenticity at entry-level prices.

The authentic slate aesthetic works particularly well in hospitality washrooms, changing facilities, and public convenience areas where the stone-look appearance suggests hygiene and quality. The riven texture provides inherent slip resistance ideal for wet environments, while the Knight Tile pricing makes it viable for larger-scale commercial projects where natural slate would be cost-prohibitive.

TECHNICAL EXCELLENCE
Karndean Knight Tile Black Riven Slate ST15 features advanced multi-layer construction engineered for long-lasting performance:
K-Guard+ Surface Protection: The innovative K-Guard+ coating with PU technology creates a hygienic, durable surface that resists everyday wear, spills, and scuffs. This advanced protection makes cleaning effortless – simply sweep and mop with Karndean Clean. Unlike natural slate which can be porous and require sealing to prevent staining, K-Guard+ eliminates the need for specialist treatments while providing superior stain resistance and hygiene. The surface protection enhances the riven texture, maintaining the authentic slate appearance while delivering practical benefits natural stone cannot match.
0.3mm Wear Layer: This substantial wear layer protects the high-definition slate design from everyday wear and tear, ensuring your floor maintains its dramatic appearance throughout its 15-year residential warranty period. Suitable for both residential and moderate commercial applications, the wear layer provides excellent indentation resistance and recovery, crucial for heavy furniture and high-traffic areas.
High-Definition Photographic Layer: Advanced printing technology captures every nuance of natural riven slate – from the deep black base tones to the subtle surface variations and texture that characterize hand-split slate stone. The result is a strikingly realistic stone aesthetic that's indistinguishable from genuine slate tile at a fraction of the cost and without the maintenance headaches.
Engineered Stability Layers: Multiple stability layers work together to minimize expansion and contraction, ensuring your slate tile pattern remains perfectly aligned regardless of temperature fluctuations. This engineered construction provides superior dimensional stability compared to natural stone, which can crack or shift with temperature changes or building movement.
Heavy-Duty PVC Backing Layer: The robust backing layer provides excellent indentation resistance and recovery, protecting against furniture marks and heavy traffic. This durable foundation ensures long-term performance even in busy commercial environments, while natural slate would require careful underlayment and could chip or crack under similar conditions.
2.0mm Total Thickness: The slim 2.0mm profile makes Black Riven Slate ideal for renovation projects where height transitions must be minimized. Install directly over existing hard floors without extensive preparation, making it perfect for updating tired spaces quickly and cost-effectively. Natural slate requires thick adhesive beds and substantial subfloor preparation – Knight Tile eliminates these complications.
INSTALLATION & MAINTENANCE
Professional Installation:
Karndean Knight Tile Black Riven Slate ST15 requires professional glue-down installation for permanent, reliable performance. The 305x457mm (12"x18") stone tile format provides authentic proportions that replicate traditional slate tile installations. Professional installers can create various patterns to suit your design vision:
Straight Lay Pattern: Install tiles in a clean grid pattern for contemporary, architectural aesthetics. This classic layout showcases the riven texture and natural variation while maintaining orderly sophistication.
Offset/Brick Pattern: Stagger tiles in a traditional brick-bond pattern for authentic stone floor heritage. This offset installation adds visual interest while creating the appearance of naturally laid slate flooring common in traditional country properties.
Mixed Layout: Combine Black Riven Slate with other Knight Tile stone designs in lighter tones (such as T100 Cumbrian Stone or T101 Portland Stone) to create custom patterns with tonal contrast. This approach works beautifully for defining zones within open-plan spaces or creating feature areas.
Design Strip Enhancement:
Enhance your Black Riven Slate floor with Karndean Design Strips to create authentic grouting effects between tiles. The 3mm or 5mm Design Strips simulate traditional grout lines, adding even greater realism to the slate aesthetic. Consider:
Design Strips also allow you to create custom borders using the optional Windsor border system mentioned for this design, or to frame rooms with contrasting wood or stone tones from the wider Knight Tile collection.
Windsor Border Option:
Black Riven Slate ST15 has an optional matching Windsor border available, allowing you to create professional framed installations. Use the Windsor border system to define room perimeters, create feature panels, or add architectural detailing to your slate floor. This traditional detailing adds bespoke character at entry-level prices.
No Expansion Gaps Required:
The gluedown installation method means no expansion gaps are required – tiles fit tight against walls, fixtures, and cabinetry for a seamless, professional finish identical to traditional grouted slate installations.
Underfloor Heating:
Black Riven Slate ST15 is fully compatible with underfloor heating systems up to 27°C, bringing added warmth and comfort to your slate-look floors. Unlike natural slate which can feel uncomfortably cold underfoot, this luxury vinyl flooring provides superior thermal comfort even without heating. When used with underfloor heating, it responds quickly to temperature changes and distributes warmth efficiently.
Simple Maintenance:
One of Knight Tile's greatest advantages over natural slate is the effortless maintenance. Simply sweep or vacuum regularly to remove loose dirt and grit, then damp mop with Karndean Clean for sparkling results. The K-Guard+ surface protection means no sealing, no specialist slate treatments, and no worrying about acidic spills etching the surface. Spills wipe away easily without staining – wine, coffee, oils, and even harsh cleaning chemicals won't damage the surface as they would natural slate.
The riven texture appearance is printed and protected rather than physically textured, making cleaning easier than genuine riven slate where dirt can accumulate in the surface crevices. You get the aesthetic beauty of riven slate with smooth, hygienic surfaces that won't harbour dirt or bacteria.
Should any tile become damaged over time, individual tiles can be replaced without redoing the entire floor – a significant advantage over traditional slate installations where matching replacement tiles can be difficult to source and integrate seamlessly.
DESIGN INSPIRATION
Contemporary Black Interiors:
Black Riven Slate's deep tones suit contemporary minimalist interiors where dark floors anchor bright white walls and sleek furnishings. The natural slate texture adds organic warmth and visual interest to otherwise stark spaces, preventing them from feeling too sterile or cold. Pair with metallic accents in brass, copper, or brushed steel for sophisticated industrial-contemporary style, or combine with natural wood elements for earthy Scandinavian-influenced contrast. The riven texture provides tactile interest that elevates minimalist schemes beyond flat, monotonous surfaces.
Traditional Country Aesthetic:
In traditional country properties, Black Riven Slate delivers authentic stone flooring heritage. The riven texture evokes historic stone floors found in farmhouses, cottages, and period properties throughout the UK. Pair with exposed oak beams, rustic furniture, and traditional country décor for cohesive heritage styling. Use in kitchen diners to create farmhouse kitchen authenticity, in boot rooms for practical country living spaces, and in hallways for traditional stone floor welcome. The black slate aesthetic suits both coastal cottages seeking rugged natural materials and countryside retreats embracing rural heritage.
Industrial-Natural Fusion:
Black Riven Slate bridges industrial and natural design aesthetics beautifully. The deep black tones suit urban loft conversions and warehouse apartments, while the natural slate texture softens hard industrial edges. Combine with exposed brick, steel fixtures, and concrete elements for authentic industrial style, or mix with living greenery and natural textiles for biophilic design that brings nature into urban spaces. The slate aesthetic works particularly well in open-plan living where natural stone grounds contemporary architecture.
Spa-Like Bathrooms:
Create boutique hotel luxury in home bathrooms by using Black Riven Slate for dramatic slate-inspired wet rooms. The waterproof construction and riven texture combine to deliver spa aesthetics with practical performance. Pair with white sanitaryware for classic black-and-white contrast, natural wood vanities for earthy warmth, or brass fixtures for contemporary luxury. The slate aesthetic suggests natural materials and organic wellness, perfect for creating calming bathroom sanctuaries. Consider using Black Riven Slate on floors and combining with lighter Knight Tile stone tiles for walls (using Karndean's LooseLay format) to create coordinated wet room styling.
Zoning & Definition:
Use Black Riven Slate strategically to define spaces within open-plan layouts. Create a kitchen zone with slate-look tiles while surrounding living areas feature Knight Tile wood planks for visual contrast and spatial definition. Install slate tiles in entrance hallways to create durable threshold zones that handle outdoor debris, then transition to wood planks for living spaces. The dramatic black slate naturally draws the eye and anchors design schemes, making it perfect for creating focal points.
Mixed Stone Patterns:
Combine Black Riven Slate with other Knight Tile stone designs for custom installations:
Practical Commercial Design:
For commercial applications, Black Riven Slate creates robust, professional first impressions in reception areas and entrances. The deep black tones hide soiling in high-traffic areas, reducing visible maintenance requirements. The slate aesthetic suggests quality and permanence, ideal for care home communal areas, student accommodation hallways, hospitality public spaces, and retail changing facilities. The riven texture provides inherent slip resistance crucial for safety in wet areas and entrance zones.

WHY CHOOSE KNIGHT TILE BLACK RIVEN SLATE ST15
Affordable Stone Luxury: Enjoy the authentic aesthetics of premium riven slate at entry-range prices. Knight Tile delivers genuine stone beauty without the premium price tag of natural slate or high-end LVT collections.
100% Waterproof Performance: Unlike natural slate which can be porous and susceptible to staining, Black Riven Slate is completely waterproof and stain-resistant. Perfect for bathrooms, wet rooms, boot rooms, and kitchens where real slate would require extensive sealing and ongoing maintenance.
No Sealing Required: Natural slate requires regular sealing to prevent staining and moisture penetration. Knight Tile eliminates this ongoing maintenance expense and effort completely. K-Guard+ surface protection provides permanent stain resistance without any additional treatment.
Warmer Than Real Slate: Luxury vinyl provides superior thermal comfort compared to natural stone, feeling noticeably warmer underfoot even without underfloor heating. Real slate can feel uncomfortably cold, especially in bathrooms and hallways during winter months.
Won't Crack or Chip: Natural slate is brittle and can crack under impact or building movement. Knight Tile's flexible construction eliminates these concerns, providing durable performance that won't fracture or chip like stone.
Authentic Riven Texture: High-definition printing captures every nuance of hand-split riven slate, creating virtually indistinguishable aesthetics from genuine slate tile – but with smooth, easy-clean surfaces rather than textured crevices that harbour dirt.
Individual Tile Replacement: Should any tile become damaged, individual tiles can be replaced without redoing the entire floor. With natural slate, matching replacement tiles can be impossible to source, requiring extensive repairs.
Perfect for Renovations: The 2.0mm thickness makes installation straightforward even in renovation projects with tight height restrictions. Install over existing hard floors without the thick adhesive beds and extensive preparation required for natural slate.
Easier Installation: Natural slate requires experienced stone layers, thick adhesive beds, and careful subfloor preparation. Knight Tile installs faster with standard LVT installation methods, reducing labour costs significantly.
Lighter Weight: Luxury vinyl is substantially lighter than natural slate, eliminating structural load concerns in upper floors, renovations, or properties with weight restrictions.
Quieter & Softer: Luxury vinyl provides superior acoustic properties compared to slate, reducing noise transmission and creating more comfortable living environments. The slight cushioning underfoot is gentler on joints during prolonged standing – important in kitchens and utility areas.
Hygienic & Family-Friendly: Won't harbour dust, dirt, or allergens like carpet, and easier to maintain hygienically than porous natural stone. Safe for children and pets with slip-resistant riven texture appearance and smooth, splinter-free surface.
Consistent Appearance: Natural slate varies dramatically between batches, making additions or repairs visually obvious. Knight Tile provides consistent appearance with controlled natural variation, ensuring seamless repairs or future additions.
No Grout Maintenance: When installed with Design Strips, there's no porous grout to seal, clean, or replace. The vinyl Design Strips remain pristine without the discoloration, mould growth, and deterioration common with traditional grouting.
Quick Installation: Faster to install than traditional slate tile, reducing labour costs and minimizing disruption to your home or business. No grouting time or sealing waiting periods.
15-Year Residential Warranty: Comprehensive warranty coverage provides peace of mind that natural slate cannot match. Knight Tile is engineered to last, backed by Karndean's confidence in their products.
Budget-Conscious Projects: Ideal for rental properties, student accommodation, care homes, housebuilds, and commercial projects where slate aesthetics must coexist with tight budgets. Knight Tile delivers authentic stone appearance at prices that make larger-scale projects viable.
Underfloor Heating Compatible: Works seamlessly with modern heating systems, providing energy-efficient warmth throughout cold months. Responds faster to temperature changes than natural slate's thermal mass.
