Product Overview


The Handmade 304 SS Undermount Kitchen Sink represents the pinnacle of artisanal craftsmanship combined with industrial durability, designed for discerning homeowners and culinary enthusiasts. Each sink is meticulously handcrafted from 16-gauge (1.5mm thick) 304 stainless steel by skilled artisans, ensuring exceptional quality and attention to detail. The undermount design creates a seamless transition between sink and countertop, maximizing workspace while providing a sleek, modern aesthetic. With exterior dimensions of 30x22 inches and an 10-inch bowl depth, it offers ample capacity for large cookware and messy kitchen tasks. The hand-polished interior and subtly brushed exterior resist scratches and stains, maintaining their appearance even with heavy use. This handmade stainless steel sink brings both functional excellence and artisanal character to any kitchen design.


Product Features


Handcrafted 304 Stainless Steel

Each sink is individually handmade from high-grade 304 stainless steel with a 16-gauge (1.5mm) thickness that provides superior strength and durability. The 304 alloy contains 18% chromium and 8% nickel, offering exceptional corrosion resistance, preventing rust and discoloration even when exposed to food acids, salt, and cleaning agents. The handmade construction ensures precise welding and finishing, with each sink featuring unique subtle variations that reflect the artisan's craftsmanship. Unlike mass-produced sinks, the handmade process allows for thicker material in high-stress areas, enhancing long-term durability.


Undermount Design

The undermount installation creates a streamlined look with no rim interrupting the countertop surface, making cleanup easier and maximizing usable counter space. This design allows water and crumbs to be swept directly into the sink without catching on a rim, promoting a more hygienic kitchen environment. The sink mounts securely beneath the countertop, supported by heavy-duty brackets that distribute weight evenly, accommodating the weight of large pots and full water capacity without stressing the countertop. The undermount design works beautifully with solid surface countertops including granite, quartz, and marble.


Hand-Finished Surfaces

The sink features a hand-polished interior that creates a smooth, reflective surface resistant to food buildup and easy to clean. The exterior and rim receive a satin brushed finish that hides minor scratches and complements modern kitchen appliances. Artisans hand-finish each sink to ensure consistent quality, with rounded corners and smooth transitions that enhance both aesthetics and functionality. The hand-polishing process removes any burrs or imperfections, creating a safe, comfortable surface that won't snag on sponges or dishcloths.


Enhanced Functionality

Designed with practicality in mind, the sink includes several functional features including a sloped bottom that ensures complete water drainage, preventing standing water. The 10-inch bowl depth accommodates large cookware and reduces splashing, while the generous 30x22 inch dimensions provide ample workspace for food preparation and cleanup. Drain grooves channel water toward the drain opening, which is offset to provide more usable space in the cabinet below for plumbing connections. The sink's design also minimizes noise, with natural sound-dampening properties enhanced by the thick 16-gauge material.


How to Install


Installation of an undermount sink requires careful planning and is best completed during countertop installation. Begin by ensuring your cabinetry is properly reinforced to support the sink's weight—approximately 45 pounds empty, plus the weight of water and contents. The minimum cabinet size required is 33 inches to accommodate the 30x22 inch sink.

Work with your countertop fabricator to create a precise cutout that matches the sink's dimensions, typically 29x21 inches for a 30x22 inch sink, with proper support ledges around the perimeter. The countertop material must be solid surface (granite, quartz, etc.)—undermount sinks are not recommended for laminate countertops.

Apply a generous bead of high-quality silicone sealant to the rim of the sink. Carefully position the sink beneath the countertop cutout, ensuring it is centered and level. Secure the sink to the countertop from below using the provided undermount brackets, spacing them approximately 6-8 inches apart around the perimeter.

Tighten the brackets gradually and evenly to ensure the sink makes full contact with the countertop without warping. Allow the silicone sealant to cure for 24 hours before proceeding with plumbing connections to ensure a proper bond.

Connect the drain assembly according to the manufacturer's instructions, ensuring a watertight seal with plumber's putty or silicone. Install the faucet on the countertop following its specific installation guidelines. Once all connections are complete, turn on the water supply and check for leaks, making any necessary adjustments.


FAQ


What makes a handmade sink different from a mass-produced one?

Handmade sinks feature superior craftsmanship with attention to detail that mass-produced sinks often lack. Skilled artisans individually weld, polish, and finish each sink, ensuring consistent quality and addressing any imperfections during production. Handmade sinks typically have thicker material in critical areas, stronger welds, and smoother finishes. Each handmade sink also has subtle unique characteristics that reflect the artisan's work, adding character you won't find in identical mass-produced models.

How do I care for and maintain my handmade stainless steel sink?

Daily care involves rinsing with warm water and wiping with a soft cloth. For regular cleaning, use mild dish soap and a non-abrasive sponge, avoiding harsh chemicals or abrasive cleaners. To maintain the finish, apply a stainless steel cleaner quarterly, following the grain direction. Prevent water spots by drying the sink after use, especially in hard water areas. Avoid leaving acidic foods or standing water in the sink for extended periods, and use a bottom grid to protect against scratches from cookware.

Can this sink be installed in an existing countertop?

While best installed with new countertops, undermount sinks can be retrofitted into existing solid surface countertops by a professional. This process requires cutting the existing countertop to create the proper opening and installing support brackets. It's more complex than installing with new countertops and should only be attempted by experienced countertop professionals to avoid damaging the existing countertop.

Does the handmade nature affect the sink's warranty?

No, reputable manufacturers back their handmade sinks with warranties comparable to or better than mass-produced models, typically lifetime warranties on material defects and craftsmanship. The careful construction process often results in fewer defects, and manufacturers stand behind the quality of artisan craftsmanship. Be sure to follow care instructions and register your sink to activate the warranty, retaining proof of purchase and installation records.
