Who it fits

Key specs explained for ATTOP sink

Material: Stainless Steel

This material provides a durable, non-porous surface that resists rust and corrosion. You can scrub it without worrying about damaging the finish. It pairs well with stainless steel dishwashers and faucets for a cohesive look. The brushed finish helps hide water spots and minor scratches better than polished metal, keeping the kitchen looking clean with less effort.

Steel Gauge: 20 Gauge

Gauge indicates thickness, where a lower number means thicker steel. At 20 gauge, this sink offers solid durability for daily use. It is less prone to denting than thinner 22-gauge options. This thickness helps dampen noise when water hits the basin or when you place heavy pots inside. It is a practical choice for households that wash large cookware regularly.

Installation Type: Undermount

Undermount sinks attach beneath the countertop, leaving the counter edge exposed. This design allows you to wipe crumbs and debris directly into the basin without a rim getting in the way. It creates a seamless look that matches modern kitchen aesthetics. Ensure your countertop material, such as granite or quartz, is suitable for this installation style before proceeding.

Bowl Configuration: Single Bowl

A single bowl offers one large, uninterrupted workspace. This is ideal for washing large items like baking sheets or stock pots that might not fit in a double-bowl sink. You can use accessories like cutting boards or drying racks across the width. It is particularly useful if you have a dishwasher, as you only need one basin for pre-rinsing or soaking.

Exterior Dimensions: 30 x 18 inches

These measurements define the footprint of the sink on your counter. The 30-inch width provides ample space for washing multiple items side by side. The 18-inch depth from front to back ensures stability and prevents items from sliding off. Verify that your base cabinet is at least 33 inches wide to accommodate this sink and allow for proper plumbing and mounting hardware installation.

Build Quality and Design Details

According to the listing, this sink is constructed from 20-gauge stainless steel. This thickness provides a solid feel and helps resist dents during heavy use. The exterior measures 30 inches wide by 18 inches deep, with a height of 9 inches. It weighs 19 pounds, which suggests a sturdy build that requires a secure undermount installation. You will need a minimum cabinet size of 33 inches to accommodate this unit properly.

The finish is described as a commercial-grade brushed satin stainless steel with a nano coating. This coating is designed to repel oil stains and reduce floating rust, making daily cleaning easier. The surface wipes clean with minimal effort, matching most modern kitchen appliances. The design includes a 10mm radius corner for easier scrubbing and a slanted bottom with elegant drain grooves to improve water flow efficiency.

Layout features include a single bowl configuration and a rear drain placement. This positioning ensures dishes do not settle directly on the drain, protecting both the strainer and your cookware. The sink includes a stainless steel basket strainer to trap food waste. It also comes with a cut-out template and mounting hardware for installation. The universal 3.5-inch drain opening fits standard garbage disposal units, ensuring compatibility with common kitchen setups.

Setup and Daily Use Guide

Installing this undermount sink requires a minimum 33-inch cabinet. The cutout dimensions are 28 inches by 16 inches. The listing includes mounting brackets and a template to help with placement. You need to ensure your cabinetry meets these size requirements before beginning installation. The USA standard 3.5-inch drain opening allows compatibility with most garbage disposal units. This universal fit simplifies the connection process for your waste disposal system.

Daily use benefits from the nano coating technology. This layer prevents scratches and resists oil stains. Floating rust is less likely to adhere to the surface. Water beads up and flows off easily, similar to the lotus leaf effect. This feature reduces the effort needed for routine cleaning. The commercial grade brushed finish also helps hide dirt and grime. You can wipe the surface clean with minimal scrubbing.

The sink design includes a 10mm radius corner. This curve eliminates sharp edges that trap debris. The slanted bottom and elegant drain grooves guide water toward the rear drain. Dishes do not settle directly on the drain opening. This positioning keeps food waste contained in the stainless steel basket strainer. You can easily remove the strainer and empty it into the trash. The heavy-duty sound guard undercoating and thick rubber padding reduce noise during washing. Condensation buildup is also minimized, keeping the exterior cabinet drier.

Before You Buy This Sink

Before you buy this ATTOP sink, verify your cabinet space. The listing requires a minimum 33-inch cabinet for proper installation. You must also confirm your countertop cutout matches the 28-by-16-inch dimensions. This undermount design demands precise cutting, so professional help may be necessary if you lack experience. Check your existing garbage disposal compatibility. The sink features a standard 3.5-inch drain opening, which fits most common disposal units. However, you should measure your current unit to ensure a seamless fit. Regarding upkeep, the nano coating helps resist stains and rust, but you should still clean it regularly to maintain the brushed finish. Avoid abrasive pads that could damage the surface. When comparing this to other options in our 1 dishwasher guide, consider how the sink size affects your workflow. A single bowl offers more room for large pots, which complements efficient dishwashing cycles. Ensure your faucet and sprayer align with the sink’s rear drain placement for optimal ergonomics.

Check before you buy

• Verify your cabinet is at least 33 inches wide.
• Confirm your countertop cutout is 28 by 16 inches.
• Check if your garbage disposal fits the 3.5-inch opening.
• Ensure you have tools for precise undermount installation.
• Plan for regular cleaning to maintain the nano coating.
