This attop 33 inch large single review focuses on the ATTOP 33-Inch Drop-In Single Bowl Sink. It measures 33 inches wide by 22 inches deep with a 9-inch bowl depth. The sink uses 20-gauge stainless steel for the basin and a 3.0mm edge plate. It installs as a drop-in model into your countertop. You get a single bowl configuration, which offers a large, continuous workspace. The listing highlights a nano coating and brushed finish for easier cleaning. We look at how these specifications affect your daily kitchen tasks and durability over time.
What stands out
- 20-gauge stainless steel bowl construction for durability
- 33-inch width with 22-inch front-to-back depth
- 9-inch bowl depth for handling large pots
- Nano commercial-grade brushed finish resists stains
- Heavy-duty sound guard and rubber padding reduce noise
Who it fits
Good fit for
This sink suits homeowners with standard 33-inch countertop cutouts who need a large, single workspace. The 9-inch depth helps you wash bulky items like roasting pans or baking sheets without water splashing. The drop-in installation is straightforward for DIYers or quick replacements. If you prefer a minimalist look with a single basin, this model fits. The sound dampening features also make it a practical choice for open-concept kitchens where noise travels easily to living areas.
Who should skip it
You should look elsewhere if you need a double-bowl setup for separating washing and rinsing. This model only comes in a single bowl configuration. If your countertop requires a 32x21-inch cutout, this sink fits, but verify your space first. It is not designed for undermount installation, as it is a drop-in style. Buyers seeking a black finish in this specific 33-inch size may need to check other variations, as the primary listing describes a silver stainless steel finish. It also lacks a built-in drying rack, though it includes a grid.
Verdict: The ATTOP 33-inch sink offers a spacious, durable single-bowl design with effective noise reduction. It is a solid choice for kitchens needing a large, easy-to-clean workspace.
Key specs explained for ATTOP
Bowl Configuration: Single Bowl
This sink features one large basin rather than two smaller compartments. This design maximizes available space for washing oversized items like baking sheets or large pots. You can submerge bulky cookware without fitting them into a narrow secondary bowl. This configuration suits households that prioritize washing large dishes over simultaneous draining and scrubbing. It is ideal if you need a wide, uninterrupted surface area for cleaning.
Steel Gauge: 20 Gauge
The basin is constructed from 20-gauge stainless steel, which indicates a thickness of approximately 0.0359 inches. This gauge offers a balance between durability and weight, providing better resistance to denting than thinner 22-gauge options. It helps maintain the structural integrity of the sink during daily use. When comparing sinks, lower gauge numbers mean thicker metal. This thickness ensures the sink feels sturdy and reduces noise during operation.
Installation Type: Drop in
This is a top-mount sink that rests on the countertop with a visible rim. Installation involves placing the sink into a pre-cut hole and securing it from above. This method is generally easier and less expensive to install than undermount styles. It creates a seal that directs water into the basin, protecting the cabinet edge from moisture. This type is suitable for standard countertops and simplifies replacement of existing sinks.
Exterior Dimensions: 33 x 22 inches
The sink measures 33 inches in width and 22 inches in depth. These dimensions require a countertop cutout of 32 by 21 inches. This size fits standard 36-inch base cabinets, providing a generous workspace for washing. The depth ensures the sink is substantial enough for heavy-duty cleaning tasks. You must verify your cabinet opening size before purchasing. This footprint is common for large single-bowl sinks in modern kitchens.
Design and Build Analysis
The ATTOP 33-Inch Drop-In Single Bowl Sink is constructed from stainless steel with a 20-gauge basin thickness. The listing specifies a 3.0mm edge plate for the rim. This combination of materials aims to provide structural rigidity while maintaining a slim profile. The exterior dimensions are 33 inches wide by 22 inches deep, requiring a countertop cutout of 32 by 21 inches. This size fits standard kitchen cabinetry layouts. The single bowl configuration offers a large, uninterrupted workspace. You can accommodate bulky items like large pots and baking sheets without the obstruction of a divider.
The finish is described as a nano commercial grade brushed surface. According to the listing, this coating prevents scratches and resists oil stains and floating rust. Liquid is said to bead up similarly to water on a lotus leaf, which simplifies cleaning. The satin finish is intended to match most kitchen appliances and resist dirt. A stainless steel bottom rinse grid is included. This grid protects the sink surface from scratches and serves as a drying rack for dishes.
Underneath the basin, heavy-duty sound guard undercoating and thick rubber padding are installed. These materials minimize noise during use and reduce condensation. The drain placement is rear-facing with a 3.5-inch opening. This standard size fits most garbage disposal units. The rear placement ensures that dishes do not settle directly on the drain, keeping waste contained in the basket strainer for easy disposal.
Setup and everyday use
Installation requires a countertop cutout measuring 32 inches by 21 inches. This fits the 33-inch by 22-inch exterior dimensions of the sink. The drop-in design places the rim on top of your counter, simplifying the mounting process compared to undermount styles. You must ensure the cutout matches the specified size for a proper fit.
The drain is positioned at the rear. This placement keeps dishes from settling directly over the opening, allowing you to stack pots and pans more effectively. The basin offers a 9-inch depth, providing ample room for tall items. The 3.5-inch drain opening is a standard US size, meaning it works with most garbage disposal units available on the market.
Daily cleaning is supported by a nano coating on the surface. This layer helps prevent oil stains and floating rust from adhering to the stainless steel. Liquid beads up and rolls off, similar to water on a lotus leaf. The brushed finish resists dirt and grime, allowing you to wipe the surface clean with minimal effort.
Underneath, heavy-duty sound guard undercoating and thick rubber padding reduce noise during use. A stainless steel bottom rinse grid protects the basin floor from scratches. This grid also functions as a drying rack for washed items. The included stainless steel basket strainer traps food waste, which you can easily remove and empty into the trash.
Check Fit And Maintenance
Before purchasing this ATTOP sink, verify your countertop cutout measures exactly 32 by 21 inches. The 33 by 22 inch exterior requires precise spacing. Confirm your garbage disposal unit fits the standard 3.5-inch drain opening. Rear drain placement keeps dishes away from the drain, but you must check clearance for disposal mounting hardware. This sink uses a drop-in installation, meaning the rim rests on the counter. Ensure your counter material can support the weight of the 20-gauge stainless steel basin and water load. The nano coating helps resist oil and rust, but you should still wipe it dry after use to maintain the brushed finish. While this guide focuses on dishwashers, this sink serves as the primary washing station. Its single bowl design accommodates large pots that may not fit in smaller dishwashers. Check if your faucet holes align with the sink’s pre-drilled options or if you need an adapter. Proper maintenance of the stainless steel surface ensures longevity and keeps the satin finish looking clean.
Check before you buy
- Verify countertop cutout is 32 by 21 inches.
- Confirm garbage disposal fits the 3.5-inch drain opening.
- Check faucet hole alignment or adapter needs.
- Ensure counter supports the sink weight and water load.
