Undermount 30/70 Double Bowl Offers a spacious 21-inch by 16-inch by 10-inch right bowl and a 9-inch by 16-inch by 8-inch left prep bowl for multitasking flexibility.
18-Gauge T304 Stainless Steel Constructed from premium-grade stainless steel to ensure long-lasting durability and resistance to everyday wear.
Zero-Radius Design Features sharp, clean angles and flat bottom ledges that capture a modern, minimalist aesthetic.
MegaShield Sound Insulation Minimizes clatter from pots and pans while preventing condensation from forming underneath the sink cabinet.
Rear-Set Drains Maximizes usable basin space and improves water drainage by shifting the drain placement backward.
Scored Drain Lines Directs water efficiently toward the 3.5-inch drain opening to prevent pooling at the bottom of the sink.
Understanding Zero-Radius Corners and Water Drainage
Zero-radius sinks feature sharp, 90-degree interior angles rather than traditional curved basin corners, delivering a sleek architectural look. Think of it like moving from a rounded wading pool to a crisp geometric lap pool; the straight walls and flat bottom maximize interior volume and create a bold, modern silhouette. To ensure water and debris do not get trapped in those sharp corners, this sink is engineered with precision-scored drain lines etched into the floor. These subtle channels help guide water effortlessly toward the rear-set drain, combining striking minimalist geometry with everyday functionality.
Installation Guide
Verify that your base cabinet measures at least 36 inches wide to properly accommodate the overall 33-inch by 18-inch frame.
Use the included cutout template to carefully mark and trace the undermount sink opening on your countertop material.
Apply a high-grade silicone sealant along the top rim of the sink before pressing it firmly against the underside of the countertop.
Secure the sink in place using the provided mounting clips, tightening them evenly to ensure a stable, flush hold.
Wipe away any excess silicone sealant immediately and let the installation cure completely before connecting plumbing fixtures.
Care & Maintenance
Daily Cleaning Wash the sink after each use with warm water, mild dish soap, and a soft sponge to prevent residue buildup.
Rinsing Rinse the stainless steel surface thoroughly after cleaning to remove soap film and maintain its lustrous satin finish.
Grain Direction Wipe and dry the sink in the direction of the metal polish lines to preserve the smooth texture.
Preventing Stains Avoid leaving wet cast iron pans or harsh chemical bleach sitting on the stainless steel surface for extended periods.
Avoiding Scratches Use a protective bottom grid if desired to shield the flat zero-radius floor from abrasive cookware scratches.

Crafting a Resilient and Timeless Kitchen Workspace
Investing in a high-grade stainless steel sink transforms the heart of your home into a durable, hygienic sanctuary that stands up to decades of culinary activity. The T304 stainless steel alloy used in this model offers exceptional resistance to rust, thermal shock, and everyday impact, ensuring that your investment maintains its structural integrity through countless family dinners and holiday gatherings. Unlike porcelain or composite materials that may chip or stain over time, a brushed satin stainless steel surface develops a gentle, uniform patina that ages gracefully alongside your cabinetry. By combining industrial-grade metal composition with refined architectural geometry, this sink delivers a long-term sanitary solution that keeps your kitchen looking pristine with minimal upkeep.
Beyond its striking visual appeal and robust material strength, this undermount double bowl fixture is engineered to enhance the overall ergonomics and environmental harmony of your kitchen routine. The strategic 30/70 basin split optimizes water usage by allowing you to fill only the smaller left bowl for quick rinsing tasks, conserving resources without sacrificing workspace. Meanwhile, the dense MegaShield undercoating absorbs acoustic vibrations, contributing to a quieter home environment while actively preventing condensation from collecting inside your cabinet base. Choosing a meticulously crafted Houzer sink means bringing professional-grade culinary reliability and thoughtful everyday efficiency right into your residential space.
