Wholesale 8-Inch Deep Kitchen Sinks for Multifamily & Commercial Projects

Wholesale 8-inch deep kitchen sinks are the standard depth specified across U.S. multifamily and residential construction — deep enough to handle most cookware and contain splashing, shallow enough to maintain comfortable reach across user heights. Developers, general contractors, and procurement teams default to 8-inch for standard apartment, hospitality, and senior living kitchens; 7-inch is the ADA/clearance-constrained alternative, 9-inch is the premium upgrade. Allora USA stocks 8-inch deep sinks across widths from 23 to 33 inches in single-bowl and double-bowl, undermount and drop-in. Allora Advantage handles trade pricing, fixture-schedule coordination, and phased delivery across the project timeline.

Frequently Asked Questions

8-inch deep sinks are available across all standard widths from 23 to 33 inches in single-bowl and double-bowl, undermount and drop-in. The 8-inch depth changes vertical clearance inside the cabinet but not external sink dimensions.

8-inch is the default depth for standard non-accessible kitchens — the right call when no ADA requirement applies, no cabinet clearance constraint exists, and no premium unit positioning justifies the 9-inch upgrade. Specify 7-inch for ADA units or tight clearance; specify 9-inch when basin capacity is a unit-differentiation feature.

Standard 8-inch depth does not meet ADA knee clearance requirements. For accessible units, Allora offers shallow-depth ADA sinks in matched product families — same external dimensions and visual style as 8-inch deep sinks, with ADA-compliant basin depth.

Yes. Allora produces 8-inch and 9-inch sinks in the same product families — matched finish, radius profile, and external dimensions. Project teams specify 8-inch in standard units and 9-inch in premium units within a single order while maintaining matched style.

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
