Wholesale Tight Radius Kitchen Sinks for Multifamily & Commercial Projects

Wholesale tight radius kitchen sinks feature small corner radii (typically R15) — a contemporary interior profile that reads modern without the 90-degree corner cleaning consideration of zero radius. Developers, general contractors, and procurement teams source tight radius across mid-tier and luxury multifamily, hospitality residences, and design-forward residential where the contemporary aesthetic matters; standard radius (R30+) is the cost-efficient default for value-tier and standard multifamily, zero radius is the most aggressive contemporary option. Allora USA stocks tight radius sinks in stainless steel undermount across widths from 23 to 33 inches. Trade accounts coordinate premium-unit fixture packages, phased delivery, and documentation through the Allora Advantage program.
