Quartz countertops are an increasingly popular choice for kitchen and bathroom remodels due to their durability, aesthetics, and easy maintenance. When selecting quartz, one of the biggest decisions is choosing the right thickness for your needs. This comprehensive guide covers everything you need to know about quartz countertop thicknesses to make the best choice for your home.
Standard Thicknesses for Quartz Countertops
Quartz slabs are cut into the following standard thicknesses:
- 3/4 inch – This is the most common and affordable thickness for quartz countertops. A 3/4 inch slab is sturdy enough for most residential uses.
- 1 1/4 inches – A step up in thickness, 1 1/4 inch slabs add more depth and dimension to your countertops. This thickness offers increased sturdiness.
- 2 cm – 2 cm is equivalent to roughly 3/4 inch. This European measurement is becoming more popular for quartz fabrication.
- 3 cm – 3 cm equals 1 1/4 inches. This thicker slab is widely used overseas.
Factors to Consider When Choosing Quartz Thickness
When deciding what quartz thickness is right for your project, keep the following considerations in mind:
Aesthetics
Thicker quartz countertops make a bolder visual statement. The additional depth and dimension show off the veining and patterns within the material. A 1 1/4 inch slab has presence and weight that a thinner 3/4 inch piece lacks.
Overhangs, backsplashes, islands or any areas with exposed edges will be more prominent with a thicker quartz top. Visually, the thickness enhances these design features.
Durability
Quartz is an extremely durable material resistant to scratches, stains and heat. However, thicker slabs are less prone to damage over time.
With a sturdier base, they can better withstand daily wear-and-tear. Thicker countertops are less vulnerable to cracks or breaks from bumps, knocks or excessive weight placed on them.
Support for sinks and appliances
Standard sinks and counter appliances require solid support underneath. A 3/4 inch quartz countertop provides an adequate base in most cases.
However, some sinks or appliances may dictate a need for 1 1/4 inch or thicker material. Things like heavy stone vessel sinks and commercial grade appliances benefit from the stability of thicker quartz below.
Overhangs
An overhang refers to a countertop that extends past the cabinetry below. This creates visual space and a handy area to pull up stools for an eat-in kitchen island.
The thicker the quartz material, the more support it provides to overhangs. A longer overhang of 6-12 inches should have a 1 1/4 inch or thicker slab to prevent sagging over time.
Weight
Quartz is made from roughly 90% crushed natural stone blended with resins and pigments. This makes an entire slab quite heavy. Thicker quartz tops add significant weight.
Make sure your cabinetry and support structures are built to easily handle the load bearing down. Also factor in challenges with moving and installing unwieldy jumbo slabs.
Budget
Not surprisingly, thinner 3/4 inch quartz is the most budget friendly option. As thickness increases to 1 1/4 inch and beyond, the price per square foot rises accordingly. There is more fabricated material, plus thicker slabs weigh more, adding to shipping costs.
Matching Edges
When designing adjacent areas with different quartz thicknesses – like a kitchen island meeting a countertop – the finished edges may not perfectly align. There are ways to smooth and shape borders for an integrated look. However, some difference in heights is typical.
Family Use
Active families with kids and constant activity do well with 1 1/4 inch quartz for added durability. The rigidity stands up to rambunctious households over years of use. For those seeking bulletproof surfaces, opt for the thickest quartz possible.
Standard Thicknesses by Area
Beyond the above considerations, quartz thickness needs vary depending on the functional use of the space. Here are typical quartz thicknesses by location:
Kitchen Countertops
For most kitchen settings, 3/4 inch quartz provides adequate strength and support. The majority of homeowners select this most affordable and widely available thickness.
Island overhangs beyond 6 inches may benefit from 1 1/4 inch to prevent bowing under weight. For heavy-use kitchens or solid surface sinks above the norm, consider thicker quartz up to 2 cm.
Kitchen Backsplashes
Backsplashes normally use 3/4 inch quartz fabricated into a matching panel. 1 1/4 inches can create a backsplash that stands out with added volume.
Bathroom Vanities
Standard bathroom sinks and lighting fixtures generally work fine with 3/4 quartz vanity tops. Double check measurements for vessel or other stone sinks that require extra support underneath.
For bathrooms seeking a luxurious feel, 1 1/4 inch quartz vanities make a distinctive design statement.
Outdoor Kitchen Countertops
Outdoor entertaining areas call for maximum durability. Go for 1 1/4 inch or thicker quartz able to withstand temperature swings, UV rays, storms and the elements.
Bar Countertops
For home bars and entertainment rooms, thinner 3/4 inch quartz provides functionality. If regularly accommodating guests leaning on or sitting at the bar area, consider a 1 1/4 inch top or thicker.
Laundry Room Countertops
With minimal use, laundry rooms only require standard 3/4 inch quartz. This delivers convenience for folding and sorting clothes with resilience to detergents and dyes.
Quartz Thickness Recommendations
Here is a quick reference for recommended quartz thicknesses:
- Standard residential kitchen counters – 3/4 inch
- Kitchen islands with 6-12 inch overhangs – 1 1/4 inch
- Heavy stone vessel sinks – 1 1/4 inch or thicker
- Commercial grade appliances – 1 1/4 inch or thicker
- Active households with kids – 1 1/4 inch
- Bathroom vanity tops – 3/4 inch
- Outdoor kitchens – 1 1/4 inch or thicker
- Home bars – 3/4 inch or 1 1/4 inch
- Laundry room counters – 3/4 inch
Achieving the Right Thickness
Quartz slabs come pre-cut from the manufacturer in set thicknesses of 3/4 inch, 1 1/4 inch, 2 cm or 3 cm. The fabricator cannot adjust or modify the depth.
For specialized projects, combining two thinner pieces can add thickness. This requires extra fabrication and seams. The result may have slight visual differences compared to a solid thicker slab.
If unable to source your ideal thickness, remember thickness is just one aspect of an overall countertop design. Work with experienced quartz pros to maximize durability and aesthetics through proper installation and edge details.
Cost Differences by Thickness
As a general guide, here are approximate quartz countertop costs by thickness:
- 3/4 inch quartz countertops installed – $40-80 per square foot
- 1 1/4 inch quartz countertops installed – $70-120 per square foot
- 2 cm (3/4 inch) quartz countertops installed – $40-90 per square foot
- 3 cm (1 1/4 inch) quartz countertops installed – $70-130 per square foot
Exact pricing varies by supplier, design complexity, edge profiles and local labor costs. Be sure to factor in your overall budget when weighing thickness decisions. A thinner quartz top may allow for a larger installation area.

Achieving Thicker Edges
Quartz thickness refers to the overall slab depth. Edges can be built up beyond the slab thickness via edge profiles. Decorative edges add depth and customize the finished look.
Common ways to increase edge thickness include:
- Step down design – The quartz slab rests on a thicker border for definition.
- Thickened edge – Adding a strip of material builds up select edges.
- Laminated edges – Adhering additional quartz to edges achieves extra thickness.
- Wooden accents – Wood edging paired with quartz makes a bold impact.
How Thick of a Quartz Overhang is Safe?
A standard residential 3/4” quartz countertop should safely overhang a base cabinet by up to 6”. This span provides room for bar stools or design aesthetic without sagging.
For overhangs extending 6-12 inches, a 1 1/4” slab or thicker provides adequate structural support. Over 12” is not recommended without an underlying brace or corbel.
Always follow manufacturer rules of thumb for maximum overhang by thickness. Reinforcing overhangs is also an option if you desire an aggressive cantilevered look.

How to Choose Faucets for a Quartz Countertop
An important yet often overlooked decision when designing a kitchen or bath with quartz countertops is choosing complementary faucets. The style, finish, configuration and functionality of your faucets impact both aesthetics and ergonomics. Follow this essential advice for selecting the perfect faucets to match your new quartz countertops.
Factors to Consider
Design Style
Look for faucets aligned with your desired design style – modern, traditional, farmhouse, industrial, etc. The faucet visuals should integrate and not conflict with countertop textures and colors.
A sleek modern quartz island pairs best with minimalist, high-arching faucets, not old school brass. Make sure faucet styling complements your overall vision.
Metal Finishes
Popular faucet finishes include polished chrome, brushed nickel, matte black, bronze, brass, copper, and more. Choose metal finishes that coordinate well with your quartz’s veining patterns and undertones.
Avoid matching a warm brass faucet with cool grey and white quartz. Seek cohesion between metals against the quartz backdrop.
Number of Handles
For a streamlined look, a single-handle faucet provides control of hot and cold water in one place. Dual-handle faucets have a more classic appeal. Decide between one or two handles based on aesthetics and functionality.
Spout Height/Reach
Consider the sink depth and configuration when selecting faucet height and reach. High-arching faucets clear vessel sinks, while low-profile styles maximize workspace next to shallow undermount sinks.
Water Pressure
Look for faucets rated for good water pressure. Quartz’s non-porous surface accentuates weak pressure. The faucet should provide adequate flow through the spout and pull-down/pull-out wands if present.
Integration
For a unified look, choose widespread faucets and handles that align with the shapes and lines of your quartz countertop and sinks. Custom faucet configurations can seamlessly integrate with your design.
Budget
As with most fixtures, faucet pricing spans a wide range. Have realistic expectations when matching affordable quartz with higher-end hardware. Seek harmony in finishes over perfect parity in costs.
Special Features
Consider special functions like touch-free motion sensors, smart home connectivity, hot/cold water filters, soap dispensers, LED lights, and adjustable wands. Know which unique faucet features matter most for your needs.
Faucet Styles for Quartz Countertops
Kitchen Faucets
The optimal kitchen faucet aligns with your sink type while offering convenience and flexibility through movable wands and sprays.
Pull-down spray faucets are popular for prep tasks. High-arc gooseneck styles make a statement. For modern styles, minimalist single-handle faucets integrate well with quartz.
Bar/prep faucets in a secondary work zone create a harmonious kitchen faucet “suite”.
Bathroom Faucets
Widespread faucet configurations allow creative combinations with quartz vanity tops. Waterfall faucets are on-trend statement pieces.
Vessel and undermount sinks need properly paired heights/clearances. Wall-mount faucets conserve space atop floating quartz vanities.
Laundry and Utility Room Faucets
Laundry faucets should provide adequate pressure for washing tasks with a convenient swiveling spout. Garage utility sinks pair well with sturdy wall-mount or industrial-style faucets.
Outdoor Kitchen Faucets
For outdoor entertaining areas, look for faucets with freeze-proof technology along with hand sprayers. Integrated soap dispensers add convenience by the grill or wet bar sink area.
Tips for Choosing Faucet Finishes with Quartz
Match metals to quartz veins – Select faucet finishes containing metal tones found in the countertop coloring. Brushed nickel picks up on grey veining. Oil-rubbed bronze reflects hints of brown.
** Harmonize neutrals** – For a neutral white or grey quartz, pair with chrome, nickel, or similar polished metals for crisp contrast. Don’t clash with brass or bronze.
Tone-on-tone – Alternately, choose faucet metals tonally “matching” the quartz. A black quartz island works with matte black fixtures. Copper quartz fits with rose gold hardware.
** Warm metal with cool slab** – A warm brass or gold finish faucet brings life to an icy blue-hued quartz countertop. The mix of cool and warm metals makes a pleasant dynamic.
** Avoid matching** – Directly matching the faucet metal to the quartz pattern often feels monotonous. Seek complementing finishes, not copies.
** Skew subdued** – For dramatic colored or heavily veined quartz, pick subdued faucets so the countertop steals focus. Save brass showstoppers for plain white quartz.
** Mind the edges** – Make faucet metals harmonize with countertop edges the same way they complement the slab colors. This unifies the full installation.
