In contemporary architecture and interior design, the demand for clean, uninterrupted surfaces has driven the adoption of 1600x3200 sintered stone panels. Measuring 1.6 meters wide by 3.2 meters long, each panel covers 5.12 square meters of surface area — equivalent to more than fourteen standard 600×600mm tiles. This translates directly into fewer joints, faster installation, and a dramatically elevated visual result.
For architects and designers, large-format sintered stone eliminates the fragmented, grout-heavy appearance of traditional tile work. A single panel can span an entire bathroom wall, wrap a kitchen island without interruption, or clad a continuous facade elevation with clean, monolithic lines. The result is a surface that reads as a single piece of stone rather than a collection of individual tiles.
The 1600×3200mm format is available across all three Wharton Slabs product lines, each optimized for different applications:
| Thickness | Weight | Primary Applications | Panels per 20ft Container |
|---|---|---|---|
| 3mm | ~7.5 kg/m² | Facade cladding, wall panels, furniture surfaces | ~650 |
| 6mm | ~15 kg/m² | Countertops, bathroom walls, backsplash, interior walls | ~320 |
| 12mm | ~30 kg/m² | Flooring, heavy-duty countertops, stair treads, exterior paving | ~160 |
The most immediately visible benefit of 1600×3200mm sintered stone is the reduction in visible joints. Consider a typical commercial lobby feature wall measuring 6.4 meters wide by 3.2 meters tall (20.48 m²):
For projects where marble or stone veining patterns are critical, large-format panels ensure that the natural-looking grain flows continuously across the surface. This is particularly important for Calacatta and Statuario designs where the veining is a defining aesthetic feature. Small tiles break the pattern into fragments; large-format sintered stone preserves the design intent.
Large-format 1600x3200 sintered stone is particularly well-suited to open-plan commercial environments where visual continuity creates a sense of space and sophistication:
Grand reception walls, elevator lobbies, and reception desk cladding benefit from the seamless, premium appearance that only large-format panels can deliver. The material's scratch and impact resistance ensures longevity in high-traffic zones.
Modern office design emphasizes clean lines and natural materials. 1600×3200mm panels on feature walls, meeting room partitions, and reception areas create an environment that communicates professionalism and quality. The large format is compatible with demountable partition systems for flexible office layouts.
Branded retail spaces require consistent visual language across multiple locations. Sintered stone provides uniform color and pattern that natural stone cannot guarantee. Large-format installation ensures that flagship store designs translate accurately to satellite locations.
In hygiene-critical environments, the non-porous surface of sintered stone (water absorption < 0.05%) meets strict infection control standards. Large-format panels minimize the number of joints where bacteria could accumulate, making cleaning and sterilization more efficient. The material is also resistant to harsh cleaning chemicals, including bleach and hydrogen peroxide.
Working with panels of this size requires proper planning and handling:
