22 Inch Undermount Bathroom Sink Rectangle Undermount Sink - Compact

In this review the 22 Inch Undermount Bathroom Sink is evaluated as a straightforward, reliable option for small to medium vanities where a clean, modern rectangular basin is desired. The sink's main appeal is its compact, accurate dimensions and glazed vitreous china finish, which combine to deliver a durable under-counter installation that looks crisp and is easy to maintain. It is best suited to remodels or replacements when a no-fuss, no-faucet-hole undermount is required, and the review focuses on fit, finish and practical installation considerations.

Key Features

• Size and fit: The 21.8in x 14.0in external footprint is ideal for tight vanity tops and small bathrooms where full-size sinks would overwhelm the counter.
• Material and finish: Glazed vitreous china provides a smooth, non-porous surface that resists stains and is simple to wipe clean after daily use.
• Undermount design: The sink is made for under-counter installation, producing a seamless edge with the countertop and simplifying cleanup of spills.
• Overflow protection: Built-in overflow adds practical protection against accidental overfilling in a busy bathroom setting.
• Drain compatibility: A US standard 1.75in drain opening fits common pop-up drains, though the package does not include the drain or faucet hardware.
• Rectangular profile: Vertical sides and a rectangular bowl deliver a modern look and maximize usable bowl space within the compact external dimensions.

Who It's For

The sink is a good match for homeowners and contractors fitting small vanities, powder rooms, or guest bathrooms where a neat, rectangular undermount will save counter space and create a clean appearance. It suits renovation projects that require a reliable vitreous china basin without faucet holes, allowing flexibility in countertop-mounted or wall-mounted faucet placements.

Those who should look elsewhere include buyers who need integrated faucet holes or a larger basin for heavy family use, and anyone expecting included drain hardware or a specific non-standard drain size, since the package contains only the sink with overflow.

Pros & Cons

• Compact external dimensions that fit small vanities while still offering a useful internal bowl depth.

Cons

• Pop-up drain and faucet are not included, so additional purchases and checks for hardware compatibility are required.
