Quartz vs Porcelain Countertops: A Fabricator's Guide
By The Granite Guy | Southborough, MA | Updated 2025
🎯 Quick Answer
The main difference? Quartz uses resin, porcelain doesn't.
After 30 years installing countertops across Greater Boston and MetroWest, I can tell you: quartz gives you edge profile flexibility but needs trivets for hot pans. Porcelain handles extreme heat and UV exposure but limits your design choices and works best for minimalist looks.
Choose quartz for most Massachusetts kitchens. Choose porcelain for outdoor kitchens, shower walls, or fireplaces.
✅ Key Takeaways
- Quartz contains resin, so always use trivets for hot pans
- Porcelain handles direct heat, UV, and New England freeze-thaw cycles
- Quartz allows any edge profile; porcelain is limited to thin or mitered edges
- Porcelain is gaining popularity for shower walls, bathroom walls, flooring, and fireplaces
- Never use quartz near fireplaces. The heat will crack it.
- Both are non-porous and never need sealing
- Pricing depends on brand and color tier, not just the material
What They Actually Are
Quartz countertops are engineered slabs made from 90-95% ground natural quartz bound with polymer resins. Popular brands include Silestone, Cambria, Caesarstone, and MSI Quartz.
The resin creates a non-porous surface that never needs sealing. But that resin is also why quartz can't handle high heat, and why you should never install quartz near a fireplace. Heat is one of the main causes of cracking in quartz countertops.

Porcelain countertops (also called sintered stone) are made from clays, silica, and minerals fired at over 2,000°F. Brands like Dekton, Neolith, and Lapitec dominate this category.
No resin means extreme heat resistance. You can set a hot pan directly on porcelain without damage.
But here's the thing. Porcelain's real strength isn't just countertops. It's becoming very popular across Massachusetts for shower walls, bathroom walls, flooring, and fireplaces, especially floor-to-ceiling fireplace surrounds. The thin, lightweight panels work beautifully for these applications.
For countertops specifically, porcelain works best for minimalist designs where the thin profile and clean mitered edges match the modern aesthetic.

🎨 Appearance & Design
Both materials look great. But they achieve it differently.
Quartz has color and pattern throughout the slab. Chip an edge, and the interior matches the surface. This matters for waterfall islands, a popular choice in Weston, Wellesley, and Newton kitchens where the edge becomes a design feature.
Porcelain patterns are printed on the surface. The technology is impressive. It can replicate marble, concrete, even rusted metal.
But here's what most people don't realize: the body of porcelain underneath is a solid color. The pattern is essentially a photo printed on top. When you cut the edge, that exposed edge doesn't match the surface design.

✂️ Edge Options
This is where quartz wins for design flexibility.
Because quartz is consistent throughout, we can cut any edge: eased, bullnose, ogee, bevel, dupont, waterfall. Whatever suits your Brookline colonial or your Sudbury contemporary.
Porcelain edges are different. You have two options:
- Thin profile with regular cut. Accept the thin edge as-is. Works great for minimalist, modern designs where that clean look is intentional.
- Mitered edge. We cut at 45 degrees and fold the patterned surface to create a continuation of the design, like a waterfall effect. This hides the solid-color body underneath.
The mitered approach creates extra labor and cost. Substrate buildups are required to support the thin material. But it's the only way to get a realistic, seamless look with porcelain.
🔥 Heat Resistance
Porcelain's biggest advantage.
Take a pan from a 500°F oven and set it directly on porcelain. No damage. The material was fired at 2,000°F+ during manufacturing, so your cooking temps won't faze it.
This is also why porcelain works beautifully around fireplaces. We've installed floor-to-ceiling fireplace surrounds in homes from the North Shore to Cape Cod. The heat doesn't affect it.
Quartz cannot handle heat. The resin can discolor, crack, or melt under sustained high heat. I've seen quartz counters with permanent scorch marks from hot pans, and it's not covered under warranty.
Never install quartz near a fireplace. The heat will crack it. I've seen this happen in Massachusetts homes where homeowners didn't know.
Always use trivets with quartz countertops.

💥 Impact & Chipping
Here's where quartz has the edge.
Quartz has some flex. The resin gives it resilience that absorbs impact. Drop a heavy pot, and it usually survives. We've installed thousands of quartz countertops across MetroWest and rarely see impact damage.
Porcelain is harder but more brittle. It's ceramic, after all. The edges are particularly vulnerable, and a sharp impact can chip them.
During fabrication and installation, we handle porcelain much more carefully than quartz. One wrong move and the slab cracks.
☀️ Outdoor Use & New England Weather
Planning an outdoor kitchen in your Concord backyard or Cape Cod vacation home? Porcelain is your only choice.
Porcelain is completely UV-stable. Won't fade, discolor, or degrade in direct sunlight. Handles Massachusetts freeze-thaw cycles (those swings from 90°F in August to -10°F in January) without damage.
Most quartz manufacturers explicitly void warranties for outdoor use. The resin yellows with UV exposure and can't handle New England's temperature extremes.

🚿 Shower Walls & Bathroom Applications
This is where porcelain is really gaining popularity across Greater Boston.
Porcelain's thin, lightweight panels are perfect for shower walls and bathroom walls. We're seeing more and more requests for this in Newton, Lexington, and Needham bathroom renovations.
The large-format panels mean fewer grout lines than traditional tile. They're waterproof, easy to clean, and can replicate the look of marble without the maintenance headaches.
Quartz can work for bathroom vanity tops, but porcelain is the better choice for wall applications where you need thin, light material.

🧹 Cleaning & Maintenance
Both are easy. Learning how to clean quartz countertops or porcelain is simple.
Non-porous, hygienic, clean with mild soap and water. Avoid harsh chemicals and abrasive scrubbers.
Neither requires sealing, ever. This is their shared advantage over granite and marble, which is why both materials are popular choices for busy Massachusetts families. If you're also considering natural stone, check out our quartz vs granite comparison.
🔧 Installation Differences
Quartz is heavier but more forgiving.
Standard 3cm quartz weighs 20-25 lbs per square foot. It cuts predictably and minor on-site adjustments are manageable. Seams can be nearly invisible.
Porcelain is lighter but demands precision.
About 10-15 lbs per square foot. The thin profile can sometimes overlay existing countertops.
But it's brittle. One wrong move during cutting and the slab cracks. Our fabricators use specialized diamond blades and waterjet cutting for porcelain.
For porcelain countertops with mitered edges, there's extra labor involved. We need substrate buildups to support the material properly. This adds to the installation cost.
Not every fabricator works with porcelain. If you're considering it, make sure your installer has specific experience with the material. We've been fabricating porcelain at our Southborough shop for years. Learn more about our process.
💰 Pricing Reality
Everyone wants to know about pricing, so let me be straight with you.
Both quartz and porcelain are made by many different companies. And the brand matters for pricing.
But here's what most people don't realize: every company has different pricing tiers. It comes down to supply and demand.
Some colors are more popular. They cost more. Some colors are simpler. They cost less. This happens with both quartz and porcelain (also known as sintered stone).
So it's not as simple as "quartz costs X and porcelain costs Y." Depending on the brand and complexity of your project, you can find both materials at very similar price points.
The real cost difference often comes from installation. Porcelain with mitered edges requires more labor, substrate buildups, and specialized fabrication. That adds to the total project cost.

❓ FAQs
Is porcelain or quartz better for kitchen countertops? For most Massachusetts kitchens, quartz is better. More edge options, consistent color throughout, and more forgiving if you drop something heavy. Porcelain countertops work best for minimalist designs where the thin profile fits the aesthetic. (Don't confuse quartz with quartzite, which is a natural stone.)
Can you put hot pans on porcelain countertops? Yes. Porcelain handles hot pans directly from the oven without damage. Quartz cannot, so always use trivets with quartz.
Can I use quartz around my fireplace? No. The heat will crack quartz. We've seen this happen in homes across Greater Boston. Use porcelain for fireplace surrounds. It handles the heat beautifully.
Why is porcelain popular for shower walls? Porcelain's thin, lightweight panels are perfect for wall applications. Large formats mean fewer grout lines than tile, and it's completely waterproof. We're installing more porcelain shower walls every year in MetroWest bathroom renovations.
Which costs more, quartz or porcelain? It depends on brand and color tier. Both materials are made by many companies with different pricing levels. Some colors are more popular and cost more; simpler colors cost less. You can find both materials at very similar price points. The real cost difference often comes from installation. Porcelain with mitered edges requires more labor.
Do porcelain countertops chip easily? Porcelain is harder than quartz but more brittle. The edges are most vulnerable. A sharp impact can chip them. The surface itself is very scratch-resistant.
Can you use quartz countertops outside in Massachusetts? No. Most manufacturers void warranties for outdoor use. The resin yellows with UV exposure and can't handle New England's freeze-thaw cycles. Use porcelain for outdoor kitchens.
Which has better resale value? In the Greater Boston market, quartz currently has stronger buyer recognition. But porcelain is gaining popularity, especially for outdoor kitchens and fireplace applications.
Do quartz or porcelain countertops need sealing? Neither. Both are non-porous and never require sealing. That's a major advantage over granite and marble.
📍 Making Your Decision
Both materials are excellent. Durable, low-maintenance, attractive. Neither is universally "better."
The right choice depends on where it's going: indoor kitchen, outdoor space, shower walls, or fireplace surround. It depends on how you cook, what design elements matter to you, and whether you need heat resistance.
