Buying Bathroom Sinks from Columbus Granite

Please note: Columbus Granite may not have all sink models shown in stock. We recommend contacting us to confirm availability before making any purchasing or installation plans.

We primarily carry ceramic sinks, which are the most popular choice for bathroom vanity tops due to their classic look and durability. Our porcelain sinks are available in both rectangular and oval shapes.

Rectangular Ceramic Sinks

  • 18″ x 13″ – The most common size, ideal for standard vanity cabinets and offers a spacious basin.
  • 16″ x 11″ – A more compact option suitable for smaller vanities.

Oval Ceramic Sinks

  • 17″ x 14″
  • 15″ x 12″

White is the most frequently selected color, but we also offer biscuit to match fixtures like toilets in that tone.

Installation Style

We highly recommend undermount sink installations for a seamless look and easy countertop cleaning. As a result, we do not carry drop-in sinks.

When you order a sink with your countertop, we precisely fabricate the sink cutout to ensure your sink fits perfectly. This process is customized for the specific sink model you select.

Pickup and Mounting Options

  • Pre-mounted: We can securely attach your sink to the countertop at our facility before pickup.
  • Mounting clips: If you prefer to mount the sink onsite after installing the countertop, we provide the required clips and guidance.

We do not carry vessel sinks at this time. However, customers are welcome to provide their own sinks for their projects, and we will ensure the sink cutout is fabricated with precision to match the specifications.

Understanding Bathroom Sink Types, Shapes, and Materials

Common Sink Shapes

  • Rectangular: Offers a modern look with larger basin space.
  • Oval: Traditional and soft-lined, ideal for a classic aesthetic.
  • Round: Compact and symmetrical, often used in smaller spaces.
  • Square: Sleek and contemporary for a minimalist feel.
  • Asymmetrical or Custom: Unique shapes available for designer bathrooms.

Sink Material Types

  • Porcelain/Ceramic: Most common for bathrooms—durable, non-porous, and easy to clean.
  • Glass: Stylish and often used in vessel sinks, but requires frequent cleaning and careful use.
  • Natural Stone: Adds luxury and uniqueness. Requires sealing and professional maintenance.
  • Resin or Solid Surface: Smooth, seamless appearance, available in custom shapes and finishes.
  • Metal (Stainless or Copper): Rare in bathrooms but can be striking in modern or rustic designs.

Sink Installation Types Explained

  • Undermount: Installed below the countertop surface for a clean edge. Best suited for stone or quartz countertops. Columbus Granite will fabricate your sink cutout with exact measurements for a perfect fit.
  • Drop-in: Also known as self-rimming. These are easy to install but leave a raised lip around the sink. Not stocked by Columbus Granite.
  • Vessel: Sits on top of the countertop. A dramatic visual option but requires specific faucet heights and base support. Customers can provide their own vessel sinks for cutout fabrication.
  • Wall-mounted: Installed directly to the wall, freeing up vanity space. Common in small or commercial bathrooms.
  • Pedestal: Includes a base and sink unit. Classic and elegant, but with no storage beneath.

Things to Consider When Choosing a Bathroom Sink

  • Cabinet and vanity size: Make sure the sink fits proportionally within the available space.
  • Faucet configuration: Some sinks require single-hole faucets, others accommodate widespread or wall-mounted options.
  • Countertop material: Undermount sinks pair best with stone or quartz tops. Columbus Granite can help ensure compatibility with your selected materials.
  • Design goals: Choose a sink shape and style that aligns with your overall bathroom aesthetic.
  • Cutout precision: Accurate sink cutouts are essential for durability and fit. Columbus Granite ensures all sink openings are professionally fabricated to match your sink model and countertop material.

If you’re planning a bathroom remodel or simply replacing your vanity top, understanding your sink options—and how they’re installed—can make a big difference. Whether you choose to purchase a sink through us or bring your own, we’re here to make sure your countertop and sink are fabricated to work together flawlessly.
