When to Use This Checklist
This checklist is for anyone making a purchasing decision between quartz and granite for a commercial or multi-unit residential project. I’ve been in procurement for over a decade, and I’ve seen this decision go wrong more often than it goes right. If you’re managing a budget and don’t have time to get burned by a ‘cheaper’ option, this is for you.
We’ll go through six steps. Each one has a check-point. Miss one, and you’re asking for trouble.
Step 1: Define Your ‘Per Square Foot’ Budget (Correctly)
This sounds obvious, but everyone gets it wrong. The price you see in the showroom is rarely the final cost. I learned this the hard way after my fourth project.
The check-point: Get a written quote that itemizes material, fabrication, edging, sink cutouts, and installation. Ask for it to be broken down by each slab.
If I remember correctly, the industry average for a basic granite slab is around $50–$60 per square foot (as of Q1 2025). Quartz is often in the $60–$80 range. But that’s just the material. I once had a project where the material was $55, but after adding a ‘standard’ eased edge and a single sink cutout, it jumped to $78. That’s a 40% hidden markup.
(Note to self: always ask for the ‘all-in’ price before comparing.)
Step 2: Verify the ‘Is Quartz Cheaper Than Granite?’ Assumption
The common wisdom is that quartz is cheaper because it’s engineered and doesn’t require sealing. I’ve found this to be a dangerous oversimplification.
The check-point: Don’t compare a mid-range granite to a premium quartz. Compare the same quality tier, or, more importantly, the same visual outcome.
I assumed ‘engineered stone’ meant lower maintenance costs. Didn’t verify. Turned out the ‘affordable’ quartz we chose had a high-gloss finish that showed every single fingerprint and water spot. We ended up spending more on daily cleaning supplies than we saved on the per-slab cost. The TCO over five years was higher. It wasn’t until we audited our 2023 spending that I saw the line item for cleaning agents had doubled from the previous project.
So, is quartz cheaper than granite? The answer is: it depends. In my experience, for high-traffic commercial kitchens, a good mid-range granite (around $60/sq ft) often wins on TCO because you seal it once and forget it. For a lobby where aesthetics are king, a satin-finish quartz might be worth the premium. But you have to run the numbers on YOUR usage.
Step 3: The ‘Color & Pattern’ Check (Most People Skip This)
Granite is a natural stone. No two slabs are identical. Quartz is engineered, so you can get consistent color across a large project.
The check-point: Ask to see the actual slab that will be used. For granite, do not rely on a small sample. The sample might look gray, but the slab you get could have a massive orange vein running through it.
I knew I should go to the warehouse to select slabs, but thought, ‘a sample is close enough.’ That was the one time it mattered. We ordered ‘Santa Cecelia’ granite for a 30-unit apartment building based on a sample. The delivered slabs had a completely different undertone. We had to re-do the entire kitchen order for 20 units. $1,200 mistake on wasted cutouts alone.
For quartz, the risk is pattern repetition. Some brands have a ‘bookmatched’ pattern that repeats every 4 feet, which looks terrible on a long island. Check the pattern repeat distance.
Step 4: The ‘Edge Profile’ Trap
Here’s where the ‘budget’ filler becomes real money. A basic ‘eased’ edge is often included. Anything else—waterfall, ogee, bevel—is a premium.
The check-point: Get the price for a standard edge and the price for the edge you want. Don’t assume a bullnose is standard.
In my experience, a customized edge profile can add 15-30% to the fabrication cost. After comparing 8 vendors over 3 months for a single project, I found that one shop charged $15 per linear foot for a bevel, while another charged $40. The cheaper one was using a mitered bevel that was structurally weaker. We switched to the $40 option after a sample broke under a normal load test. That test saved us an estimated $8,000 in potential rework.
Step 5: The ‘Sealing & Maintenance’ Reality Check
Granite needs sealing. Quartz does not. This is the single biggest differentiator people use to push quartz. But the reality is more nuanced.
The check-point: Calculate the 5-year cost of sealing. A can of high-quality sealer costs about $30. For a commercial kitchen, you might need to seal twice a year. That’s $60 a year in materials, plus labor.
I compiled a spreadsheet after my third mistake: sealing a large granite island took a worker 2 hours. At $25/hr labor, that’s $50 per seal. Doing it twice a year is $100/year. Over 5 years, that’s $500. If the quartz alternative costs $5 more per square foot on a 40 sq ft island, that’s a $200 upfront difference. Suddenly, the ‘maintenance-free’ quartz isn’t the clear winner.
Step 6: The Written Guarantee (Not the Verbal One)
Skipped the final review because we were rushing on a past project. We had a verbal agreement on a warranty for chipping. Guess what? Chipped a corner during installation. The vendor said ‘wear and tear.’ We had no paperwork to fight it.
The check-point: Get the warranty in writing. Specifically, ask about:
- Chipping (especially on quartz, which can be brittle)
- Staining (granite, if not sealed)
- Thermal shock (quartz can crack from hot pans)
- Fabrication defects (seams splitting)
I learned never to assume the proof represents the final product after receiving a batch of quartz that looked nothing like what we approved. The written guarantee is your only safety net.
Final Notes & Common Mistakes
Per FTC guidelines, claims about ‘non-porous’ or ‘stain-proof’ surfaces must be substantiated. Ask for the lab results. Quartz is non-porous, but stains can still occur on the surface finish.
One more thing: delivery. I want to say you can just schedule it, but don't quote me on that. Delays are common. The price was competitive for the quartz, but the lead time was 6 weeks (circa November 2024). I should add that we’d been with a previous supplier for 5 years because they could deliver in 10 days.
Five minutes of verification on these six points beats five days of correction. Always.
