A 27-inch kitchen sink is typically installed in a 30-inch base cabinet. This provides the standard 1.5 inches of clearance on each side needed for undermount mounting hardware and countertop support.

A 27-inch sink offers a meaningful step up in basin area from the 25-inch size while fitting a smaller cabinet than the 30-inch. For projects with 30-inch base cabinets, a 27-inch sink is the natural pairing. If the floor plan includes 33-inch cabinets in larger units, project teams may want to compare the 27-inch with the 30-inch to determine which provides the best balance of basin capacity and consistency across unit types.

They provide solid basin capacity while fitting within the 30-inch cabinet, which is a common standard in apartment units, student housing, and residential developments. The size works well for one-bedroom and two-bedroom layouts where the kitchen needs full functionality without oversizing the sink relative to the countertop.

ADA compliance depends on the full installation — bowl depth, counter height, knee and toe clearance, pipe protection, and faucet operability all factor in. Allora USA offers ADA-supportive models at this width with shallow bowl depths (typically 5.5 inches) that share the same finish and radius profiles as standard-depth sinks. Final compliance should be confirmed by the project's architect or code consultant.

For most multifamily and residential projects, single bowl is the standard. It maximizes usable basin area within the 27-inch footprint, which residents generally prefer for handling cookware and food preparation. Double bowl configurations are available for hospitality and senior living settings where separating wash and rinse functions is a design priority.

Allora USA offers 27-inch sinks in standard radius, tight radius, and zero radius profiles, in both single bowl and double bowl configurations. Single bowl is the most common specification for residential and multifamily kitchens at this size.
