Wholesale 33-Inch Kitchen Sinks for Multifamily & Commercial Projects

Wholesale 33-inch kitchen sinks are the most commonly specified kitchen sink size in U.S. multifamily and residential construction, paired with the 36-inch base cabinet that defines the standard full-size kitchen layout. Developers, general contractors, and procurement teams source 33-inch sinks for full-size multifamily, hospitality, and senior living kitchens where the project budget supports the larger cabinet footprint — 30-inch is the practical alternative when 36-inch cabinets aren't in the floor plan. Allora USA stocks 33-inch sinks in undermount, drop-in, farmhouse, and ADA-compliant configurations across single-bowl and double-bowl layouts. Trade accounts coordinate premium-unit fixture packages, phased delivery, and documentation through the Allora Advantage program.

Frequently Asked Questions

A 33-inch kitchen sink typically fits a 36-inch base cabinet — the most common kitchen sink base cabinet width across U.S. multifamily and residential construction. The 1.5-inch clearance leaves room for mounting and plumbing.

33-inch is the full-size default — specify when unit floor plans support a 36-inch cabinet. 30-inch is the practical step down when the floor plan uses 33-inch cabinets; 32-inch is the option when 33-inch reads too aggressive against the 36-inch cabinet edges.

Undermount, drop-in, farmhouse (apron-front), and ADA-compliant in single-bowl and double-bowl layouts. Materials include stainless steel, fireclay, and granite composite. 33-inch has the widest configuration range of any kitchen sink size in the lineup.

Yes. Allora offers ADA-compliant 33-inch sinks in the same product families as standard sinks — matched finish, cabinet fit, and external dimensions. Project teams specify both within a single order 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.
