17 Inch Undermount Bathroom Sink - Compact Rectangular Porcelain Sink

In this review of the 17 Inch Undermount Bathroom Sink the bottom line is simple: this compact rectangular porcelain sink is aimed at homeowners who need a high-quality, space-saving undermount basin for a powder room, guest bath, or small bathroom. The single biggest reason to buy is its balance of durable ceramic construction and a practical overflow feature, which together offer reliable everyday use without taking up precious counter space. Installation is straightforward for standard undermount setups, making it a solid choice for DIYers and renovators seeking a tidy, deep basin.

Key Features

• Compact dimensions: The 17.25in x 12.25in x 6.75in footprint fits most countertops and makes it ideal for small bathrooms or vanity tops with limited space.
• Overflow protection: Built-in overflow prevents water from rising too high, protecting cabinets and floors from accidental spills or blocked drains.
• Ceramic construction: High-quality porcelain ceramic provides strong resistance to scratches and chips for long-term durability.
• Premium glaze: A smooth, baked-on glaze creates a non-porous surface that resists stains and is easy to clean with routine household cleaners.
• US and Canada standards: Manufactured to meet regional plumbing standards for dependable fit and performance in typical installations.
• Standard drain opening: Works with a US standard 1.75in drain, simplifying compatibility with common drain assemblies and pop-up options.

Who It's For

This sink is well suited for homeowners remodeling a small bathroom, a powder room, or a guest bath where counter space is limited but a quality finish is still desired. Its compact size and understated rectangular design also make it a good match for rental properties, cabins, or bars where a neat, deep basin is preferred.

Those who need a larger, multi-user main bathroom sink or who want an integrated countertop-sink combo should look elsewhere, since the compact undermount shape is optimized for space savings rather than double-sink layouts or very wide vanities.
