CUPC Kitchen Sink

CUPC certification is of great significance in both the Canadian and US markets, particularly in the construction and engineering sectors.

Our company is proud to offer a range of CUPC certified stainless steel sinks that fully comply with industry standards, providing assurance and reliability to customers looking to purchase CUPC certified products for their projects.

CUPC (Canadian Uniform Plumbing Code) certification is a seal of quality and safety, ensuring our stainless steel sinks meet and exceed the strict plumbing and mechanical standards required for safe and reliable use in a variety of applications.

In the Canadian market, compliance with CUPC requirements is not only necessary but mandatory for plumbing products, including sinks. Likewise, in the United States, CUPC certification is significant, meaning our sinks have been tested and approved to meet the strict plumbing standards set by both countries.

The critical importance of CUPC certification in the engineering and construction fields cannot be underestimated. The CUPC sink not only means adhering to building codes and regulations but also ensuring the highest quality and safety standards.

By offering CUPC certified stainless steel sinks, we give our customers confidence that our products are not only reliable but also meet necessary industry standards. In the competitive construction and engineering sectors, CUPC sink certification demonstrates the quality and reliability of our products. CUPC sink provides a baseline of compliance and performance and assures our customers that they are selecting a product that has been rigorously tested and approved.

Characteristics of CUPC Kitchen Sink

Crafted from stainless steel, this sink features a seamless design with zero-radius corners and a rounded radius, making it not only easier to clean but also capable of retaining its original luster with just household cleanser and a soft towel. Enhanced with thick undercoating and sound-dampening pads, it includes a standard 3.5” (90mm) drain opening to accommodate various sink accessories. Its versatile installation options—topmount, undermount, and flushmount—cater to the requirements of most settings. These handmade sinks boast an expanded indoor space, extending the sink body horizontally for a pronounced wire-frame effect, enhancing both the aesthetic appeal and the sense of structure. The design is characterized by its straight sides and defined edges, lending a more textured and robust appearance. The precision of handmade craftsmanship allows for a seamless under-mount installation, effectively preventing water leakage.

Constructed from either 304 or 316 stainless steel, these sinks are shaped through laser cutting, sheet metal bending, and welding, ensuring durability and quality. The manual grooves are notably thick, typically ranging from 1.2mm to 1.5mm, with the option to increase the thickness up to 2mm or more for added flexibility in size. This meticulous attention to detail and quality materials make these handmade sinks a superior choice for enhancing the functionality and elegance of any space.
