Each ceramic undermount basin is finished in a glossy white glaze and supplied in color White across the full range. The glazed ceramic surface gives a smooth, uniform appearance suited to both residential and commercial bathroom specifications. White-tone consistency from batch to batch matters when basins appear on a showroom wall or across repeated units in a development, and finish references are available on request to support reorders. Additional material details and finish specifications are set out on the spec sheet.
All four models are designed to mount beneath the countertop, with the rim set below the counter surface for a clean edge where the countertop meets the basin. Each size has its own cutout footprint, and the matching cutout dimensions and mounting templates are provided on request so fabricators can cut the opening accurately. The drawings show a 1.8 in (45 mm) drain opening with a 2.8 in (70 mm) reference dimension.
Overflow configuration is confirmed by model at the quotation stage. For installation planning, the drain must match the overflow condition: a basin supplied without an overflow is paired with a non-overflow free-flow drain, while a basin supplied with an overflow uses a standard pop-up drain rated for overflow basins. The correct drain pairing for each model is documented on the spec sheet before the order is placed.
