The Project Standard: R30 Deep Drawn Undermount Sink

Streamline your construction or renovation projects with our 540x440mm Pressed Undermount Sink. Utilizing advanced deep-drawn technology, this sink is crafted from a single sheet of premium SUS304 stainless steel. This one-piece construction eliminates welds, ensuring leak-proof durability and a uniform grain finish, making it the preferred choice for high-volume hotel, apartment, and residential developments.

R30 Radius: Designed for Hygiene

Unlike sharp zero-radius sinks, this model features R30 Rounded Corners. The gently curved corners are:

Easy to Wipe: Eliminates blind spots where food debris and bacteria typically hide.
Aesthetically Soft: Offers a classic, transitional look that complements any kitchen style.
Maintenance Free: Perfect for busy households or rental properties where low maintenance is key.

Deep Bowl Capacity

Despite its compact 21-inch footprint, the sink offers a generous 210mm (8.3″) depth. The 500x400mm bowl provides ample space for stacking dishes and washing medium-sized pots, maximizing utility in compact kitchens.

Premium Finishes Available

Elevate the standard pressed sink with our high-end surface treatments. Beyond the classic Brushed or Satin finish, we offer Nano PVD Technology in:

Nano Black / Gunmetal: Modern, sleek, and fingerprint-resistant.
PVD Gold: Adds a touch of luxury to wet bars or high-end suites.

Wholesale Note: This pressed sink series offers excellent cost-efficiency for bulk orders. Stackable packaging is available to maximize container loading quantity (perfect for 20GP/40HQ shipping).
