Installation type and countertop material are the primary cost drivers. Undermount sinks require stone or solid surface countertops with polished edges and mounting hardware — higher material and labor cost per unit. Drop-in (top-mount) sinks seat into a standard cutout and work with laminate — significantly faster and cheaper to install. Bowl configuration matters too: single bowl has one cutout and one rough-in per unit; double bowl does not add meaningful install complexity but increases SKU count. At scale, the undermount-vs-drop-in decision and the countertop material choice drive more total cost variation than the sink itself.

Sink size is driven by cabinet width. A 23-inch sink fits a 27-inch cabinet. A 30-inch sink fits a 33-inch cabinet. A 33-inch sink fits a 36-inch cabinet. The general rule is the sink should be at least 3 inches shorter than the base cabinet width for proper undermount clearance. For projects with multiple unit layouts, Allora USA can build a specification package that matches each floor plan's cabinet configuration.

Single bowl undermount in stainless steel is the default across most multifamily and residential specifications. Single bowl reduces SKU complexity, simplifies countertop templating, and gives installers one consistent rough-in per unit.

Allora USA offers kitchen sinks in 5.5-inch (ADA-supportive), 7-inch, 8-inch, 9-inch, and 10-inch bowl depths. 8 inches is the industry standard for most projects — it accommodates everyday cookware while clearing garbage disposals and standard plumbing. 9- and 10-inch depths are upgrade specifications for premium units. 7-inch works for compact layouts with under-counter clearance constraints.

ADA compliance is an installation condition — bowl depth, counter height, knee and toe clearance, pipe protection, and faucet operability all factor in. A shallow-depth sink supports an accessible installation, but the fixture alone does not establish compliance. For multi-bowl sinks, only one bowl must meet clearance requirements. Allora USA offers ADA-supportive models that match the finish and material of standard-depth sinks. Final compliance should be confirmed by the project's architect or code consultant.
