Kitchen & Bar Sink Products
The six kitchen sink styles below differ by mounting method and basin design. Match each to the countertop, cabinet, and daily workload.
Top Mount Kitchen Sinks
A drop in kitchen sink sets into a countertop cutout, and its rim rests on the surface and seals with a bead of silicone. Top mount sinks are compatible with laminate, tile, wood, and stone, and they suit replacement jobs where the existing cutout stays in place.
Undermount Kitchen Sinks
An undermount kitchen sink mounts below the countertop with clips or brackets secured to the underside, leaving an exposed countertop edge. This method requires a solid surface such as granite, quartz, or solid-surface material. It removes the rim, so debris wipes into the bowl.
Dual Mount Sinks
A dual mount sink is built to install as either a top mount or an undermount unit. The same model works across laminate and stone countertops, which simplifies ordering when the final countertop material is not confirmed.
Farmhouse Apron Front Sinks
A farmhouse sink has an exposed front apron that replaces the cabinet face above the doors. It requires an apron-front sink base or a modified standard base, plus a support frame that carries the loaded weight, since fireclay and cast iron units are heavy when filled.
Workstation Sinks
A workstation sink includes an integrated ledge along the bowl walls. The ledge supports sliding accessories such as cutting boards, colanders, and drying racks, so prep and cleanup happen directly over the basin. Workstation models are available in undermount and top-mount versions.
Bar Prep Sinks
A bar prep sink is a compact single-bowl unit, typically 12 to 21 inches wide, designed for islands, wet bars, butler's pantries, and coffee stations. Outdoor kitchens call for stainless steel rated for exterior exposure. Many bar sinks use a smaller drain opening than a main kitchen sink.
How Kitchen and Bar Sinks Install and Where They Work
Mounting and Countertop Support
Top-mount kitchen sinks rely on the rim and sealant to hold position and block water from reaching the cabinet. Undermount sinks depend on clips, epoxy, or a support system, so the countertop fabricator and installer should confirm the method before the top is set.
Drainage and Plumbing Connections
Kitchen sinks use a 3-1/2 inch drain opening that accepts a basket strainer or disposal flange. Many bar sinks use a 2-inch opening with a matching drain. Both connect to a trap, vent, and supply lines like any fixture, so bar sinks need no special plumbing beyond a correctly sized drain.
Kitchens, Islands, Wet Bars, and Secondary Stations
The main difference between a kitchen sink and a bar sink is size and role. The kitchen sink handles cookware, dishwashing, and disposal use. A bar sink serves a secondary station for rinsing glassware, filling pitchers, and light food prep.
Key Specifications & Planning Steps
Size and Cabinet Fit
Confirm the manufacturer's minimum cabinet size before ordering. A common starting point is a cabinet about 3 inches wider than the sink's exterior, so a 33 inch sink fits a 36 inch base. For replacements, measure the existing cutout; a top-mount unit with a wider rim can cover it.
Material and Gauge
Stainless steel kitchen sinks are measured in gauge, and a lower number means thicker steel. Sixteen gauge resists denting better than 18 gauge under heavy use. Fireclay, cast iron, and granite composite add weight and need confirmed cabinet support. ADA-compliant models limit bowl depth to 6-1/2 inches.
Bowl Configuration, Drain Placement, and Faucet Holes
Kitchen sink configurations include single bowl, double bowl, and offset double bowl layouts. A rear or offset drain frees cabinet space for a disposal and the dishwasher drain connection. Faucet holes range from none to five; no-hole undermount sinks use faucet holes drilled into the countertop, including extra holes for a side sprayer or soap dispenser.
Choosing the Right Kitchen or Bar Sink
Narrow kitchen sink options by the countertop first: laminate points to top mount or dual mount, while stone and quartz support undermount and farmhouse installs. Next, match bowl layout to workload and confirm cabinet width. Workstation designs and large single bowls are common in current installs. Finish with kitchen sink accessories such as bottom grids, strainers, and cutting boards, which protect the basin and extend the work surface. For a secondary station, pair a bar prep sink with a compact bar faucet.
Frequently Asked Questions
What is the difference between a bar sink and a kitchen sink?
A kitchen sink is the main basin, usually 30 to 36 inches wide with a 3-1/2 inch drain that accepts a disposal. A bar sink is a compact secondary unit, typically 12 to 21 inches wide and often fitted with a 2-inch drain, used for rinsing glassware and light prep.
Should I use an undermount, top-mount, or dual-mount sink with quartz, granite, or laminate countertops?
Quartz and granite support undermount sinks, which mount below the countertop with clips or adhesive. Laminate calls for a top-mount sink, since the rim covers and seals the cut edge. A dual-mount sink installs either way, which helps when the countertop material is not final.
Do bar sinks need special plumbing?
No. Bar sinks connect to a trap, vent, and supply lines like any fixture. The main difference is drain size: many bar sinks use a 2-inch opening that needs a matching bar sink drain rather than a standard 3-1/2-inch kitchen basket strainer.
What size base cabinet do I need for a kitchen sink or bar sink?
Start with a cabinet about 3 inches wider than the sink's exterior width, such as a 36 inch base for a 33 inch kitchen sink or an 18 inch base for a 15 inch bar sink. Always confirm the manufacturer's listed minimum cabinet size.
What kitchen sink accessories are worth adding?
Bottom grids protect the basin floor from scratches, basket strainers catch debris at the drain, and cutting boards or colanders sized to the sink extend the work surface. On workstation sinks, these accessories slide along the integrated ledge.
What kitchen sink styles are contractors installing most right now?
Undermount sinks paired with quartz countertops, large single-bowl layouts, farmhouse apron-front sinks, and workstation sinks with integrated ledges are frequently specified in current installs. Bar prep sinks in islands and pantries are also common in larger kitchens.
