Understanding Quartz Countertop Thickness
Quartz countertops are available in different thicknesses, typically ranging from 1/4 inch to 3/4 inch. Two inches is considered an extra thick quartz countertop. The thickness affects the cost, weight, and stiffness of the countertop. Here are some guidelines on thickness:
- 1/4 inch – Best for vertical surfaces like backsplashes. Too thin for countertops.
- 1/2 inch – The standard thickness for most quartz countertop installations. Provides adequate durability for most homes.
- 3/4 inch – Provides additional durability for heavy usage areas. Good for kitchen counters.
- 1 inch – Ideal for kitchen islands and heavy duty use. Very durable but heavier.
- 1 1/4+ inch – Usually only needed for very large spans or commercial use. Significantly heavier.
For most residential kitchen counters, 3/4 inch provides the best balance of durability and weight. Some areas may benefit from 1 inch for additional stiffness.
When shopping for thick quartz countertops, you have several options:
Big Box Stores
Home improvement stores like Home Depot and Lowe’s have a selection of 1/2 inch and 3/4 inch stock quartz countertops available for purchase. This provides an easy and convenient option if you find an in-stock color and size you like. Cutting and fabrication are typically outsourced.
Using a local quartz fabricator gives you the most customization options. They can source slabs of any thickness and create counters to your exact specifications. Most fabricators offer 1/2 inch, 3/4 inch, and 1 inch options. This is the best choice for made-to-order sizing.
Some quartz brands like Caesarstone have dealer showrooms where you can select slabs and purchase directly from the manufacturer. This gives you the full range of colors and thicknesses. Expect to pay MSRP pricing with this option.
Several internet retailers sell quartz countertops with shipping nationwide. This can be convenient, but watch out for hidden fees and long lead times. Inspect slabs carefully before finalizing purchase.
What to Look For When Purchasing
No matter where you purchase thick quartz slabs, be sure to:
- Carefully inspect for any cracks, chips or defects before finalizing.
- Review technical documents to ensure proper thickness and specifications.
- Know what is covered under warranty and any disclaimers.
- Understand whether installation services are included or need to be hired separately.
- Get everything in writing – prices, services, timelines, thickness confirmation.
Factors That Impact Cost
The total installed cost of thick quartz countertops will depend on:
- Selected quartz material: More premium brands cost more.
- Slab thickness: 3/4″ is standard. 1″ or 1 1/4″ is premium.
- Edge treatments: Decorative edges like ogee/bevel cost extra.
- Fabrication: Complex cutting or seaming ups cost.
- Installation: Getting pros to install raises cost. DIY lowers it.
- Local market factors: Prices vary regionally based on demand.
Expect to pay $80-100 per square foot for typical 3/4″ quartz with straight edges, mid-grade material and professional fabrication/install. Thicker material, high-end quartz, and more complex fab/install adds $10-50+ per square foot.
Tips for Installation
Thicker countertops are heavier, so proper cabinet/base support is crucial. Follow these tips:
- Reinforce cabinets with additional cross-braces if needed before install.
- Ensure base units are level and plumb with no uneven gaps.
- Don’t install directly over old laminate—remove first to improve support.
- Have at least two people maneuver countertops during install due to weight.
- Use broad support strips to disperse weight, not just narrow edge strips.
- Follow adhesive manufacturer’s instructions to ensure permanent bond.
Where can I view quartz slabs in-person before purchase?
Most fabricators and big box stores have slab yards where you can go see materials before purchase. Manufacturer showrooms also have displays.
Can I install a thicker quartz countertop myself?
It’s possible for DIYers to install their own 1/2″ or 3/4″ quartz countertop carefully, but may require professional help maneuvering heavier 1″ and up slabs.
What thickness should I use for kitchen counters?
3/4″ is recommended for most residential kitchen counters. 1″ may be preferable for heavy usage zones like a chef’s kitchen.
Is it better to get a thicker quartz backsplash?
No, 1/4″ to 1/2″ is ideal for quartz backsplashes which see less wear and tear. Thicker is overkill and will increase costs.
Can you cut thicker quartz slabs on site?
Yes, fabricators have specialized tools to cut even 1 1/4″ slabs, allowing them to customize sizing. Expect on-site cutting fees.
With some planning and careful purchasing, installing thick quartz countertops can give your kitchen or bath added durability and style. Assess your needs, budget, and timeline before selecting a retailer. Inspect all materials thoroughly before purchase and install. With strong cabinets and proper support, your new 2 inch quartz countertops will last for decades to come. Work with experts like fabricators and don’t be afraid to ask questions to get the best results!
