The S3318 is a large single bowl undermount kitchen sink stamped from SUS304 stainless steel at 18 gauge (1.2 mm) for dent resistance under daily heavy use. Its standout feature is a wide basin spanning the full 33×18 footprint, giving a broad, flat washing floor for laying out cookware sheets. A protective undercoat and noise-dampening pads tame water drumming and disposal hum. The brushed finish carries a consistent grain that masks scratches across the basin face over years of service.
With a 33-inch width and an 18-inch depth dimension, the wide basin of the S3318 fits standard 36-inch sink bases while delivering maximum interior wash space. The undermount mount creates an unbroken counter-to-bowl transition that wipes clean with one pass. A centered or rear drain configuration is available to match your cabinet plumbing layout. The generous footprint suits busy family kitchens, rental units, and spec homes where wash capacity is a selling point.
SANIKB produces the S3318 wide-basin sink for builders, wholesalers, and property developers with OEM and ODM options spanning gauge, depth, corner radius, and finish.
