KOHLER Caxton Rectangle Undermount Sink with Overflow

The KOHLER Caxton is a rectangular undermount sink designed for bathroom vanities. It features an overflow drain to help manage accidental water accumulation and prevent overflow. The sink does not include faucet holes, so installation requires wall- or counter-mount faucets. Its simple white finish complements a variety of vanity styles and countertop materials.

Key features include a rectangular basin and an overflow drain, with a faucet-hole-free design to allow flexible faucet placement. Ideal for modern bathrooms seeking a clean, minimalist look with practical overflow protection.

KOHLER Verticyl 17″ Undermount Bathroom Vanity Sink


KOHLER Verticyl 17-Inch Undermount Sink with Overflow

The Verticyl undermount sink features a geometric rectangular basin with vertical sides, offering a contemporary silhouette. It includes an overflow drain, helping to prevent overflow scenarios. Like many undermount designs, it has no faucet holes, so installation requires separate wall- or counter-mount faucets. This sink pairs well with modern vanities and stone countertops.

Consider its depth and mounting requirements when planning the vanity cutout and faucet configuration. The overflow adds a safety margin for households with busy bathrooms or higher water flow.

This 24-inch undermount sink offers a roomy rectangle basin with a white vitreous china finish. It includes an overflow and is designed for under-counter installation. Its smooth glaze resists staining and makes cleaning straightforward. Faucet holes are not included, so you’ll need a compatible faucet setup to complete the installation.

Its generous width supports larger vanity configurations and can accommodate higher usage in family bathrooms. The overflow helps manage water volume without compromising the clean lines of the sink’s profile.

Kes S2008D Series Vessel Sink Drains


KES Vessel Sink Drain Without Overflow

These Kes vessel sink drains are designed for all-metal construction with brass and 304 stainless steel components, emphasizing rust resistance and durability. They feature a pop-up drain design with silicone gaskets to help prevent leaks. Note that these drains themselves do not provide an overflow feature, so compatibility with sinks that already include overflow channels should be verified.

The three-piece sealing ring construction aids in preventing leaks, and the all-metal build supports reliable long-term use in bathroom vanities that require a sturdy drain assembly.

Kes S2008D-BN / S2008D-CH Vessel Sink Drains


Kes Vessel Sink Drain with Brushed Nickel/Chrome Finish

This Kes line offers similar all-metal, rustproof performance with finishes in brushed nickel or polished chrome. Like the prior Kes product, these drains are designed without an overflow feature in the drain itself, emphasizing durability and anti-leak design. They are suitable for vessels or undermount sinks that require a high-quality pop-up drain assembly.

When pairing with a vanity that includes an overflow, ensure the sink and drain compatibility to avoid drainage conflicts and ensure proper sealing around the overflow channel.

Buying Guide: Key Considerations For Overflow Sinks

  • Overflow integration: Ensure the sink explicitly states an overflow drain to prevent overflow in case of faucet issues or high water flow.
  • Mounting style: Undermount sinks offer a seamless countertop appearance, but require precise cutouts and professional installation. Vessel sinks provide a distinct look but may affect cabinet height and plumbing layout.
  • Faucet compatibility: Many sinks list no faucet holes; plan faucet placement (wall-mounted vs. deck-mounted) accordingly and verify with your vanity’s design.
  • Material and finish: Porcelain/ vitreous china finishes resist staining and are easy to clean, while matte or metal finishes require regular care to preserve appearance and prevent corrosion.
  • Drain design: Drains with less complex assemblies and high-quality gaskets reduce leak risk. If choosing a vessel drain, confirm compatibility with any overflow on the sink.
  • Size and configuration: Measure vanity width, sink depth, and cabinet clearance. Wider sinks require larger cutouts and may impact storage beneath the counter.
  • Installation considerations: Some sinks require professional mounting to ensure proper alignment, leak prevention, and support for weight when loaded with water and used daily.
  • Maintenance: Look for smooth-glazed interiors and rounded basins to ease cleaning and minimize residue buildup around corners and overflow channels.
