These undermount bathroom sinks are manufactured in our own ceramic factory in vitreous china, so you buy factory-direct with no middleman markup. For non-ceramic items, we act as a one-stop sourcing partner, quality-controlling and consolidating from vetted partner factories. MOQ is one full 20ft container per supplier, which you mix freely across ceramic basins, toilets and other categories in a single shipment.
Undermount basins mount beneath the countertop, leaving a clean uninterrupted surface with no exposed rim. This makes wiping water and debris straight into the bowl effortless and gives projects a premium, seamless look that suits stone and solid-surface vanity tops. Drop-in models sit on top with a visible lip; undermount installation reads as higher-end, which helps importers and contractors position bathrooms at stronger price points.
Our undermount range spans compact cloakroom bowls through to generous wide-format basins, with rectangular, oval and round profiles. Each product lists overall footprint, internal bowl dimensions and drain position so you can match the cutout to your countertop. Mounting templates and tap-hole options are confirmed before production, ensuring every basin fits the fabricator's stone template precisely and reaches site ready to install without rework.
Because these basins come straight from our ceramic factory, we support OEM, ODM and private-label programs for distributors and brands. Send your drawings for OEM tooling, adapt an existing mould through ODM, or apply your logo, packaging and printed cartons under private label. Our service and efficiency keep sampling and production lead times tight, so your branded undermount bathroom sink line reaches market on schedule and on budget.
Every undermount basin is inspected for glaze integrity, dimensional accuracy and water absorption before it ships, and we support the certifications importers require. Strong service and fast response sit behind each order. After-sales responsibility is firm: any defective goods are replaced or fully compensated, and we never shirk responsibility. That commitment, plus a full price range, lets you order with confidence across entry-level and premium tiers.
