1. Product Overview

The Kraus KBU23 is a 32-inch undermount kitchen sink featuring a 70/30 double bowl configuration. Constructed from durable 16-gauge T304 stainless steel, this sink is designed for longevity and resistance to daily wear. It includes sound-absorbing pads to minimize noise and vibration, and a commercial-grade satin finish for a sleek appearance.

Key features of the KBU23 sink include:

• TRU16 Gauge Stainless Steel: Made with real 16-gauge T304 stainless steel for exceptional durability and dent resistance.
• Sound Dampening: Equipped with extra-thick pads covering over 80% of the sink base to absorb noise and vibration.
• Rear-Set Drain: Provides more usable space in the sink bowls and additional storage in the base cabinet.
• Wear-Resistant Finish: Commercial-grade satin finish offers lasting durability and is easy to clean.
• Optimized Drainage: Gently sloped bottom prevents water from pooling and facilitates efficient draining.

2. Installation and Setup

2.1 Cabinet Requirements

2.2 Included Components

The Kraus KBU23 sink package includes the following items necessary for installation and use:

• Kraus KBU23 Stainless Steel Sink
• 2 Bottom Grids (KBG-23) with soft rubber bumpers

3. Operating Your Sink

The KBU23 features a 70/30 double bowl design, offering versatile workspace for various kitchen tasks. The larger bowl is ideal for washing larger pots and pans, while the smaller bowl can be used for food preparation or as a dedicated space for utensils. The deep bowls provide ample capacity for stacking dishes.

The included bottom grids protect the sink's surface from scratches and allow water to drain freely, preventing items from sitting directly in standing water. The basket strainer and standard strainer effectively catch food debris, preventing clogs in your plumbing system.
