Choosing to upgrade your kitchen or bathroom with custom stone countertops is a major investment—and one that pays off in beauty, durability, and long-term value. But if you’ve never gone through custom stone countertop installation before, it’s normal to wonder what the process looks like, how long it takes, and what you need to prepare.

This step-by-step guide walks you through the entire installation journey so you know exactly what to expect when working with Custom Marble Design LLC, Monte Vista’s trusted stone specialists.

Why Homeowners Choose Custom Stone Countertops

Custom stone isn’t just about appearance—it’s about performance and personal customization. Whether you love the sleek consistency of quartz, the rich luxury of marble, or the natural patterns of granite, stone countertops offer:

  • Long-lasting durability

  • Heat and scratch resistance

  • High resale value

  • Elegant, timeless appeal

  • Fully customized edge profiles, finishes, and layouts

Now, let’s walk through the installation process from start to finish.

Step 1: Initial Consultation & Material Selection

Your project begins with an in-depth design consultation where you meet with a stone expert to discuss your vision, needs, and budget.

During this stage, you will:

  • Choose your preferred stone (granite, quartz, marble, etc.)

  • Explore available colors, patterns, and slab options

  • Select your finish—polished, honed, suede, etc.

  • Pick an edge profile (eased, beveled, rounded, ogee, and more)

  • Review pricing, timeline, and project scope

At this point, your contractor will inspect your space, answer questions, and make recommendations that align with your design goals.

Step 2: On-Site Measurement & Templating

Accurate measurements are the backbone of perfect installation. A technician will visit your home to create a digital template of your current countertop layout.

This includes:

  • Measuring walls, cabinets, and appliance openings

  • Marking seam placement

  • Confirming sink and cooktop cutout locations

  • Double-checking cabinet support

Templating ensures your custom stone slab is cut with exact precision.

Step 3: Fabrication of Your Custom Stone Slab

Once your template is finalized, the slab you selected moves into fabrication.

Fabrication typically involves:

  • Cutting the stone according to your template

  • Polishing edges

  • Creating sink and appliance cutouts

  • Applying finishing touches

  • Quality inspection

This step is where the craftsmanship shines—your countertop is shaped, smoothed, and prepared to perfection.

Step 4: Pre-Installation Preparation in Your Home

Before installation day, you may need to prep your space.

Common homeowner tasks:

  • Clear the countertops and surrounding areas

  • Disconnect plumbing (sink, faucet, dishwasher)

  • Remove small appliances, décor, and fragile items

  • Ensure pathways are accessible

Your installers may also remove old countertops if this service is included.

Step 5: Professional Installation Day

This is the exciting part—your custom stone countertop installation takes place.

What typically happens on installation day:

  • Installers carefully bring the stone indoors

  • The slab is positioned, leveled, and secured

  • Sink and cooktop cutouts are checked for precise fit

  • Seams (if any) are bonded, tightened, and polished

  • Edges and surfaces are inspected

  • The stone is sealed (depending on the material)

Most installations take 2–5 hours, depending on the complexity of your project.

Step 6: Final Sealing, Cleanup & Quality Check

Once installation is complete, your team will:

  • Seal the countertop surface (if required)

  • Clean the workspace

  • Test alignment and stability

  • Review maintenance instructions with you

You’ll receive guidance on cleaning, sealing frequency, and how to maintain your stone for decades of beauty.

Step 7: Enjoy Your Newly Transformed Space

Your custom stone countertop installation is complete—and now you can enjoy a stunning, functional, and long-lasting surface that elevates your entire home.

At this point, many homeowners also choose backsplash installation or additional design upgrades while the space is already being worked on.
