The Perfect Standard Upgrade: 31″ Topmount Single Bowl

Upgrade your kitchen functionality without remodeling the entire counter. Our 780x500mm Topmount Single Bowl Sink is sized to fit the most common kitchen cabinet cutouts, making it the ideal choice for renovation projects and home upgrades. Combining a generous washing capacity with industrial-grade construction, it outperforms standard builder-grade sinks in every way.

Engineered for Stability: 3.0mm Thick Deck

Standard drop-in sinks often suffer from a flexible rim that bends under the weight of heavy faucets. We have solved this issue by forging the mounting deck from 3.0mm thick stainless steel.

Zero Wobble: Provides a rock-solid foundation for modern high-arch pull-down faucets.
Flush Look: The thick, precision-cut rim sits flat against the countertop for a premium, built-in appearance.

Spacious & Deep Capacity

Don’t let the standard footprint fool you. The 730mm wide internal basin is optimized to maximize washing space.
Deep 228mm (9″) Bowl: Unlike shallow standard sinks, this deep basin easily accommodates tall stockpots and hides dirty dishes from view, keeping your kitchen looking tidy.

Handmade Precision

Features R10 Tight Radius corners that offer a sleek, rectangular aesthetic while remaining easy to clean. The sink is fully equipped with SoundGuard™ technology, utilizing thick rubber dampening pads and protective undercoating to minimize noise and prevent condensation damage to your cabinets.

Wholesale Note: The 780x500mm size is a high-volume “bread and butter” SKU. It is widely used in mid-to-high-end apartment complexes and residential renovations as a premium replacement for standard sinks.
