Our Drop-In Sink Cutouts and Installation Services

We focus on delivering precise sink cutouts, reliable mounting processes, and compatibility with various countertop materials. Our approach ensures a clean fit, durability, and a professional finish that aligns with your kitchen or bathroom design.

Precision Sink Cutout 

We use advanced measurement tools and templates to create exact cutouts tailored to your chosen sink model. This precision prevents gaps, misalignments, or instability. Each cutout is measured multiple times before cutting to maintain strict tolerances.



Our team employs waterjet or CNC cutting methods for granite, quartz, and marble surfaces. These techniques reduce chipping and ensure smooth edges. The result is a sink opening that fits perfectly without compromising the countertop’s strength.

Seamless Sink Mounting 

After cutting, we carefully mount the sink to guarantee a flush and stable fit. We use industry-standard sealants and brackets to secure the sink and prevent leaks. Our installation prioritizes both function and aesthetics.



We also inspect the sink’s alignment and water flow after installation. This step ensures your sink sits level and drains efficiently. Our process minimizes gaps that could collect dirt or moisture, maintaining cleanliness and durability.

Compatible Materials

We specialize in working with granite, quartz, and marble surfaces commonly found in Los Angeles homes. Each material requires a tailored cutting and installation method to protect its integrity.


Our team adjusts techniques based on the countertop’s hardness and thickness. For example:



  • Granite and marble: waterjet cutting for clean, precise edges.
  • Quartz: CNC cutting with protective measures against overheating.


This flexibility means we can work with your preferred surface confidently and safely.

Project Planning and Customization Options

We focus on precise measurements, tailored sink selections, and clear scheduling to ensure your drop-in sink cutout fits perfectly and is installed on time. Every step is designed for accuracy and convenience.

Consultation and Design Assessment


Our process begins with a detailed consultation. We evaluate your countertop material, kitchen layout, and sink preferences. This helps us determine the exact cutout dimensions and placement.


We also inspect the structural integrity of your countertop. Identifying any existing damage or weak spots ensures we reinforce areas as needed before cutting. This avoids future issues.


Using digital templates and measurements, we confirm the sink’s fit and style compatibility. This assessment guarantees a seamless transition between your countertop and sink.


Personalized Sink Selection


We offer guidance on sink types and brands suitable for your countertop material. Whether stainless steel, porcelain, or composite, we match the sink’s weight and size to your surface.


You can choose from various styles: single bowl, double bowl, farmhouse, or bar sinks. We discuss factors like depth, rim width, and faucet compatibility to fit your needs.


Additionally, we help select finishes that complement your countertop and kitchen design. This ensures your sink integrates smoothly with the overall aesthetic.


Timeline and Installation Scheduling


Once the design is finalized, we provide a clear timeline for cutting and installation. We coordinate to minimize disruption to your daily routine.


Our team schedules the cutout and sink installation based on countertop type and current workload. Typical projects take between one to three days.

Frequently Asked Questions (FAQs) About Drop-In Sink Cutouts and Installation


  • How much does drop-in sink installation cost in granite countertops?

    Drop-in sink installation in granite countertops typically ranges from $150 to $400, depending on the sink size, granite thickness, and cutout complexity. LA Custom Granite Quartz Marble Countertops provides competitive pricing with detailed estimates based on your specific sink dimensions and granite type. The cost includes precise cutting, edge polishing, and professional installation to ensure a perfect fit.

  • Can you cut drop-in sink holes in existing quartz countertops?

    Yes, we can cut drop-in sink holes in existing quartz countertops using specialized diamond-blade tools and proper dust collection systems. Our experienced team takes careful measurements and uses professional-grade equipment to prevent chipping or cracking during the cutting process. We ensure clean, precise cuts with properly finished edges that accommodate your new drop-in sink perfectly.

  • What's the difference between drop-in and undermount sink installation?

    Drop-in sinks sit on top of the countertop with a visible rim, while undermount sinks are attached underneath for a seamless look. Drop-in installation is generally more straightforward and less expensive, requiring only a cutout that matches the sink's outer dimensions. Undermount installation requires more precise cutting, additional support, and specialized mounting hardware, making it more complex and costly.

  • Do you provide drop-in sink cutouts for bathroom vanities?

    Absolutely, LA Custom Granite Quartz Marble Countertops provides drop-in sink cutouts for bathroom vanities in granite, quartz, and marble.

  • How long does drop-in sink cutout and installation take?

    Drop-in sink cutout and installation typically takes 1-3 hours to complete, depending on the countertop material and sink size. This includes measuring, cutting, edge finishing, and final installation. The process is generally faster than undermount installation since it requires less precision work and no additional mounting hardware. We complete the job efficiently while ensuring quality results.
