Wholesale 30-Inch Kitchen Sinks for Multifamily & Commercial Projects

Wholesale 30-inch kitchen sinks are one of the two most commonly specified sink sizes in U.S. multifamily and residential construction, paired with 33-inch base cabinets across standard apartment and full-size unit layouts. Developers, general contractors, and procurement teams source 30-inch sinks for multifamily, hospitality, and senior living kitchens that need full-basin capacity without committing to a 33-inch sink and 36-inch cabinet — the step up from 27-inch (which pairs with a 30-inch cabinet) and the practical default below 33-inch. Allora USA stocks 30-inch sinks in undermount, drop-in, farmhouse, workstation, and ADA-compliant configurations across single-bowl and double-bowl layouts. Allora Advantage handles trade pricing, fixture-schedule coordination, and phased delivery across the project timeline.

Frequently Asked Questions

A 30-inch kitchen sink typically fits a 33-inch base cabinet — the most common pairing in standard multifamily and full-size residential kitchens. The 1.5-inch clearance on each side leaves room for mounting and plumbing.

30-inch is the mid-range default — meaningfully larger basin than 27-inch while fitting a smaller cabinet than 33-inch. Specify 30-inch when the unit floor plan supports a 33-inch cabinet and the kitchen workflow calls for full-basin capacity. Use 27-inch for compact unit layouts; use 33-inch for full-size kitchens with 36-inch cabinets.

30-inch is the most versatile width in the kitchen sink lineup. Allora stocks 30-inch sinks in undermount, drop-in, farmhouse, workstation, and ADA-compliant configurations across single-bowl and double-bowl layouts.

Yes. Allora offers ADA-compliant 30-inch sinks in the same product families as standard sinks — matched finish, cabinet fit, and external dimensions. The shallow-depth ADA basin meets accessibility requirements while maintaining matched style across accessible and standard units.

Spec sheets, cutout templates, BIM files, and DXF files are available for every SKU. Trade accounts request the full documentation package through their Allora Advantage rep before finalizing the fixture schedule.

Stock orders ship same-day when placed before noon EST. Phased project orders are scheduled during spec stage — Allora Advantage members get tier pricing, dedicated rep support, hold-back inventory, and finish coordination across the full fixture package.
