Explore our CE-certified solid surface washbasins and engineered brass companion fittings designed for luxury hospitality, commercial, and high-end residential developments globally.
Backed by the formidable manufacturing heritage of Kajaria — India's premier tile manufacturer and a worldwide ceramic conglomerate — Kerovit brings unparalleled standards of industrial engineering, advanced polymer science, and strict ISO-certified quality assurance to the global stone resin countertop sink market.
Our state-of-the-art solid surface casting infrastructure incorporates zero-defect automated vacuum-casting technology, ensuring high chemical stability, non-porous structural integrity, and long-term mechanical resilience. Every single sink is rigorously certified under strict European Standards (EN 14688), offering global architectural partners a complete, turn-key sanitary solution backed by our industry-leading 10-Year Warranty Framework.
Understanding the chemical engineering, composite formulations, and structural performance parameters of high-grade stone resin countertop sinks.
Our stone resin composite utilizes an advanced blend of Aluminium Trihydrate (ATH) (65-70%) bonded with premium unsaturated polyester resin and PMMA acrylic matrix. This formulation yields extraordinary flexural strength compared to brittle vitreous china.
Subjected to extreme cycle tests (hot water at 90°C followed immediately by cold water at 15°C for 1,000 continuous cycles), our stone resin countertop sinks exhibit zero micro-fracturing, stress cracking, or surface delamination.
Infused with specialized UV light stabilizers and anti-yellowing agents, our white gel-coat surface maintains its pristine chromatic purity (Delta E < 1.2 over 10 years of natural sunlight exposure) meeting ISO 4892 standards.
| Performance Characteristic | High-Grade Stone Resin (Kerovit Solid Surface) | Traditional Vitreous China (Ceramic) | Natural Marble Countertops |
|---|---|---|---|
| Water Absorption Rate (EN 14688) | < 0.05% (Impermeable Non-Porous) | < 0.50% (Slight Porosity) | 0.20% - 2.00% (High Porosity) |
| Barcol Hardness Rating | > 65 HBa (Scratch Resistant) | Mohs 6-7 (Brittle Surface) | Mohs 3-4 (Prone to Etching) |
| Thermal Shock Resistance | Passed (EN 14688 1000 Hot/Cold Cycles) | Moderate (Prone to Thermal Craze) | Low (Vulnerable to Thermal Shock) |
| Renewability & Repairability | 100% Surface Renewable via Light Sanding | Irreparable if Chipped/Cracked | Requires Specialized Resin Filling |
| Edge Precision & Geometry | Ultra-Sharp Crisp Angles (R=2mm precision) | Rounded Distortion due to Kiln Shrinkage | High Precision CNC cut (Expensive) |
| Chemical & Stain Resistance | Resistant to Acids, Alkalis, Iodine, Hair Dyes | High Chemical Resistance | Vulnerable to Acidic Etching (Lemon, Vinegar) |
Strategic insights for B2B procurement managers, hotel developers, and architectural sourcing directors.
Global environmental mandates and European REACH directives are driving a rapid shift toward sustainable composite manufacturing. Future procurement specifications increasingly demand stone resin countertop sinks constructed with bio-based polyols and zero-crystalline silica content to mitigate health risks during on-site fabrication.
Kerovit is pioneering zero-silica solid surface technologies that incorporate recycled resin matrices without sacrificing structural tensile strength, providing commercial developers with critical LEED v4 and BREEAM sustainability points.
Hospitality projects are pivoting away from multi-piece undermount drop-in sinks toward single-piece continuous monoliths. Monolithic countertop sinks eliminate seam lines where mold and bacteria accumulate, drastically reducing commercial maintenance overhead while creating clean visual lines favored by modern minimalist luxury brands.
Our OEM custom mold capabilities enable architects to specify custom lengths, integrated drainage slopes, and integrated towel bar slots directly into the cast sink body.
When sourcing stone resin countertop sinks for large-scale hotel developments, residential towers, or healthcare facilities, verify that your manufacturer maintains full CE Certification under EN 14688 (Class 20/25/30 load tests), provides ISO 9001 quality audit reports, and offers matching PVD brassware companion systems to prevent site installation mismatches.
Inquire NowRigorous testing methodologies executed to ensure global regulatory compliance and long-term site reliability.
Sinks are subjected to a continuous downward vertical force of 150 kg (1.5 kN) applied at the front center edge for 1 hour without cracking, permanent deformation, or wall-anchor failure.
Basin internal geometry is tested with specified liquid dye solution to ensure 100% evacuation of water down the waste outlet without pooling or residual film accumulation.
Surface is exposed for 16 hours to aggressive chemical agents including ethanol, sodium hypochlorite, citric acid, methylene blue, and hair dye without color changes or pitting.
Evaluated under standard abrasion loads using Barcol Impressor to verify a minimum hardness rating of 65 HBa, assuring resistance against daily commercial wear.

CE Certification guarantees compliance with European Standard EN 14688, certifying that the stone resin sink meets strict requirements for static load testing, thermal shock endurance, surface cleanability, and chemical resistance. For hospitality developers, this translates to lower maintenance replacement costs, compliance with global building codes, and resistance to heavy daily guest usage.
Unlike vitreous china, which undergoes high-temperature kiln firing causing unpredictable shrinkage (typically 10-12%) and warped edges, stone resin is cold-cast in high-precision aluminum or fiberglass molds. This yields ultra-sharp 90-degree internal and external edges, zero dimensional warp, completely flat mounting surfaces, and unlimited custom design options (including custom lengths up to 3 meters and integrated drain covers).
Yes. Unlike ceramic sinks which feature a thin glazed shell over a porous clay body (making chips irreparable), solid surface stone resin is homogeneous throughout its entire thickness. Minor scratches, burns, or stubborn stains can be completely removed using 800-1200 grit fine sandpaper followed by light polishing, restoring the sink to brand-new condition without replacing the unit.
Standard production lead times range between 25 to 35 days upon drawing approval. For catalog products, our MOQ starts at 20 units per SKU. For custom OEM/ODM molds, prototype samples are produced within 14 days, with bulk production following mold validation. We also support full container load (FCL) mixed shipping across our faucet and basin collections.
Absolute yellowing protection is achieved by utilizing high-purity methyl methacrylate (PMMA) resin combined with specialized UV-stabilizer additives. Our solid surface formulas pass 1,000-hour accelerated QUV weatherometer testing with a Delta E color variance of less than 1.2, ensuring bright white and custom matte finishes remain color-fast even under direct sunlight.
Our countertop sinks feature standard international 45mm (1.75 inch) waste drain cutouts compatible with standard pop-up strainers (with or without overflow slots). Faucet holes can be pre-drilled at the factory for single-hole, 8-inch center-set, or left blank for wall-mounted spout configurations based on project specifications.
Every stone resin countertop sink is wrapped in protective PE film, reinforced with custom-cut molded EPS corner foam protectors, and sealed in heavy-duty 5-ply double-wall corrugated export cartons. For bulk project shipments, cartons are stacked on fumigated ISPM-15 wooden pallets and stretch-wrapped to prevent shift damage during container transit.
Yes. Kerovit provides complete, harmonized sanitaryware solutions including CE and SUS316 certified basin faucets, sensor taps, wall-mounted mixers, and pop-up drains in matching PVD finishes such as Gunmetal, Brushed Gold, Rose Gold, and Matte Black to streamline B2B procurement.
