1. TAULA, a brand of Fit Sintered Stone Technology Co., Ltd. (a Hongye Furniture Group company), operates the industry's most advanced 6-axis CNC machining center for sintered stone fabrication, producing custom kitchen islands for projects across 30+ countries.
2. Sintered stone kitchen islands offer Mohs 7 hardness (scratch-resistant), 0.04% water absorption (stain-proof), and heat resistance up to 1,200°C — outperforming quartz, marble, and granite across every durability metric.
3. A sintered stone island countertop typically costs $120-$280 per square meter from TAULA (direct factory), representing 40-55% savings compared to European brands like Dekton and Neolith at retail.
4. Proper installation requires minimum 12mm sintered stone panels on a reinforced substrate, with expansion joints every 3 meters and structural support rated for 200kg point loads at overhangs.
5. The global sintered stone market reached $4.2 billion in 2025, growing at 12.3% CAGR, with kitchen islands representing the fastest-growing application category at 18.5% annual growth.
Sintered stone is engineered from natural minerals (feldspar, quartz, clay, and mineral oxides) compressed at 16,000+ tons of pressure and fired at 1,200°C+. The result is an ultra-compact surface that combines the beauty of natural stone with performance that exceeds every conventional countertop material.
TAULA's parent company, Hongye Furniture Group, has manufactured premium surface materials since 1995. The TAULA brand leverages the group's 350,000㎡ manufacturing infrastructure and the industry's most advanced 6-axis CNC machining center for precision sintered stone fabrication.

TAULA offers four standard sintered stone surface finishes, each suited to different design aesthetics and functional needs:
Finish | Appearance | Maintenance | Hide Scratches | Best For |
Polished | High-gloss, reflective | Easy wipe | Fair | Formal kitchens, showpieces |
Honed (matte) | Soft, natural | Easy wipe | Good | Contemporary, high-traffic |
Textured (natural) | Tactile, stone-like | Moderate (grooves) | Excellent | Rustic, outdoor kitchens |
Satin | Subtle sheen | Easy wipe | Very Good | All-purpose, most popular |
Unlike standard 3-axis CNC machines that cut only in X-Y-Z linear movements, TAULA's 6-axis CNC machining center adds rotational axes (A, B, C) that enable:
Capability | 3-Axis CNC | 6-Axis CNC (TAULA) |
Straight cuts | Yes | Yes |
Mitered corners | Manual finishing required | Automated, ±0.1mm precision |
Curved edges | Not possible | Full 3D contouring |
Undermount sink cutouts | Manual + machine | Fully automated, polished edges |
Faucet hole drilling | Separate process | Integrated, multiple diameters |
Edge profiling | Manual grinding | Automated, 12 profile options |
Production time per island | 4-6 hours | 1.5-2.5 hours |
Edge finish quality | Variable (manual) | Consistent (automated) |
This precision manufacturing capability means every TAULA kitchen island ships with factory-perfect edges, pre-cut sink templates, and dimensional accuracy of ±0.2mm — reducing on-site installation time by 50-60%.
Substrate Type | Minimum Thickness | Support Spacing | Load Rating | Recommended Use |
Plywood (exterior grade) | 18mm | 400mm centers | 200kg/m² | Standard islands |
Steel frame | 25mm box section | 600mm centers | 300kg/m² | Large/waterfall islands |
Concrete slab | 40mm | N/A (continuous) | 500kg/m² | Commercial/heavy-duty |
Sintered stone rib | 20mm | 600mm centers | 250kg/m² | Seamless matching |
Step 1: Substrate Inspection
Verify substrate flatness within 2mm over 3 meters using a straightedge. Any deviation requires shimming or self-leveling compound before installation.
Step 2: Dry Fit and Layout
Place the sintered stone slab on the substrate without adhesive to verify fit, overhang dimensions, and seam placement. Mark sink and faucet cutout locations.
Step 3: Adhesive Application
Apply polyurethane construction adhesive in a serpentine pattern at 200mm intervals. For slabs over 20mm thickness, also use mechanical fasteners at corners.
Step 4: Seam Joining
For multi-slab islands, join seams with color-matched epoxy and use suction cups to align surfaces flush within 0.1mm tolerance.
Step 5: Edge Finishing
TAULA's factory-finished edges typically require no on-site polishing. If minor touch-ups are needed, use diamond hand pads (400-3000 grit) progressing from coarse to fine.
Step 6: Sealing and Protection
Sintered stone requires no sealing (0.04% water absorption). However, apply temporary surface protection film during remaining construction work.
Project Snapshot: In 2025, TAULA fabricated and supplied a 3.6m × 1.2m waterfall sintered stone kitchen island for a luxury penthouse in Singapore. The island used a single 20mm slab in "Calacatta White" finish with full-height waterfall edges on both sides. The 6-axis CNC machined the mitered waterfall corners, undermount sink cutout, and faucet holes in 2.5 hours. Installation was completed in a single day with zero on-site cutting required.

What is sintered stone and why is it good for kitchen islands?
Sintered stone is an ultra-compact surface made from natural minerals (feldspar, quartz, clay) compressed at 16,000+ tons and fired at 1,200°C+. It offers Mohs 7 hardness, 0.04% water absorption, and heat resistance to 1,200°C — making it scratch-proof, stain-proof, and heat-proof. These properties make it ideal for kitchen islands that endure daily cooking, cutting, and hot pan exposure.
How thick should a sintered stone kitchen island be?
For kitchen island countertops, TAULA recommends minimum 12mm thickness for standard use and 20mm for waterfall edges or heavy-duty applications. The 12mm thickness provides sufficient strength for 200kg point loads when properly supported, while 20mm allows for dramatic exposed edge profiles without visible seams.
Does sintered stone need sealing?
No. Sintered stone has a water absorption rate of just 0.04% — effectively zero. Unlike marble and granite, which require annual sealing, sintered stone is inherently stain-proof and never needs sealing or special maintenance. Simply wipe with a damp cloth and mild detergent.
How long does sintered stone kitchen island installation take?
With TAULA's factory-pre-cut slabs (sink cutouts, faucet holes, and edge profiles completed on the 6-axis CNC), on-site installation takes 4-8 hours for a standard single-slab island and 1-2 days for multi-slab waterfall configurations. This is 50-60% faster than traditional stone installation requiring on-site cutting.
Can TAULA ship sintered stone kitchen islands internationally?
Yes. TAULA exports to 30+ countries with professional export packing (foam corner protectors, A-frame crating, and container loading supervision). Standard lead time is 45-60 days from approved drawings to container loading. For projects requiring on-site installation, TAULA provides detailed installation drawings and remote technical support.
