Before You Go: The Three Numbers You Need
Before You Go: The Three Numbers You Need
Showing up to a slab yard without preparation is how people waste a Saturday. Three pieces of information turn a browsing session into a decision.
1. Your approximate square footage. You need this because slabs come in fixed sizes and the answer to “will one slab cover my kitchen?” drives everything. Measure the depth and length of every counter run, multiply, and add roughly 15–20% for fabrication waste, cutouts, and edge buildups. A typical Portland kitchen lands at 40–60 square feet of perimeter plus 15–30 for an island.
Standard slab sizes run roughly:
Granite and quartzite: commonly 110–125" long by 65–75" tall, usable yield around 45–55 sq ft per slab
Engineered quartz: typically 126–130" by 63–65", very consistent, around 50–55 usable sq ft
Large-format porcelain: up to 126" by 63", sometimes larger
Marble: varies widely by quarry, often smaller than granite
The practical takeaway: if your kitchen needs more than about 50 usable square feet, you are buying two or more slabs, and slab matching suddenly becomes the most important thing in the yard.
2. Your realistic all-in budget. Not your material budget — your installed budget. Slab yards are full of gorgeous stone at wildly different prices, and it is genuinely painful to fall for a $150/sq-ft exotic quartzite when your number is $70. Tell your fabricator your installed budget up front and ask them to walk you only through the groups that fit. In the Portland market in 2026, installed pricing generally runs about $55–$85/sq ft for entry granite and quartz, $85–$120 for mid-range and better quartzite, and $120–$200+ for premium marble, exotic quartzite, and bookmatched material.
3. Photos and samples of everything else in the room. Bring an actual cabinet door sample if you can get one, a flooring plank or tile, your paint chip, and a photo of your backsplash candidate and your fixtures. Stone is the one element in a kitchen that you cannot tweak later — you can repaint a wall, you cannot repaint a slab. Hold the cabinet door directly against the slab in natural light. Half the time this single act eliminates a stone that looked perfect in isolation.
One more preparation note specific to our region: bring a photo of your kitchen taken on an overcast day. Portland is overcast a lot, and warm-toned stones that sing in July can go flat and muddy under gray winter light through north-facing windows. Knowing what your real ambient light looks like most of the year is a genuine advantage.
Lots, Bundles, and Slab Matching: Why Two Slabs of the Same Name Can Look Different
Lots, Bundles, and Slab Matching: Why Two Slabs of the Same Name Can Look Different
This is the single most misunderstood part of buying natural stone, and it causes more disappointment than any other issue.
Granite, quartzite, and marble are quarried in large blocks. Each block is sliced into a sequence of slabs like a loaf of bread, and that sequence is called a bundle or lot. Slabs cut sequentially from one block look extremely similar to each other. Slabs of the same commercial name from a different block — possibly a different part of the quarry, possibly a different year — can look dramatically different in background color, vein density, and tone.
What this means practically:
If your project needs two or more slabs, they must come from the same lot. Non-negotiable. Confirm the lot number in writing on your quote. “Taj Mahal quartzite” is not a specification; “Taj Mahal quartzite, lot 4417, slabs 3 and 4” is.
Reserve or tag your specific slabs. Slab yards move inventory fast. If you approve slabs on a Tuesday and your template is three weeks out, those slabs need to be physically tagged and held for your job, not merely noted as your preference.
Ask how many slabs remain in the lot. If your kitchen needs two and only two exist, there is zero margin for a fabrication mishap or a mid-project change. Three available is comfortable.
Sequential slabs enable bookmatching. Because consecutive slabs are near-mirror images, you can open them like a book to create a symmetrical pattern — spectacular on a full-height backsplash or a waterfall island. It requires planning at selection time; you cannot decide to bookmatch after the slabs are cut.
Engineered quartz is different — but not immune
Quartz is manufactured, so batch-to-batch consistency is far better than natural stone. It is still not perfect. Large-format veined quartz patterns in particular can shift noticeably between production runs. If you are doing a big kitchen in a veined quartz, ask that all slabs come from the same production batch, and ask to see them staged side by side before fabrication.
Where you get to make a real design choice
Within a single lot you still choose which slab becomes your island. The island is the hero surface — it is seen from all sides, it is where people gather, and it is what shows up in photos. If the lot has one slab with more dramatic movement, that is your island. The quieter slabs go on the perimeter where uppers, appliances, and backsplash interrupt the field anyway. Make that call deliberately rather than letting the fabrication schedule make it for you.
How to Actually Read a Slab: What to Look At, in Order
How to Actually Read a Slab: What to Look At, in Order
Stone yards are visually overwhelming. Having a repeatable inspection sequence keeps you from being seduced by a single dramatic corner of a slab that will not survive fabrication.
Step 1: Look at the whole slab from 15 feet back
Start far away. From distance you see the actual composition — where the veining concentrates, whether the color is uniform across the piece, whether there is a busy zone and a quiet zone. This is the view that most resembles walking into your finished kitchen. Only after this should you step in close.
Step 2: Walk the full length at arm’s length
Now look for the things distance hides: pits and pinholes in the surface, resin fill that reads slightly differently than the stone, polish inconsistency, and abrupt pattern changes. Natural stone will always have some of this. You are calibrating what is acceptable to you, not looking for perfection that does not exist.
Step 3: View it in raking light
Ask to have the slab tilted, or move so a light source rakes across the surface at a low angle. This reveals surface topography — open fissures, unpolished dips, and any waviness in the finish. It is also how you see the genuine three-dimensional crystalline depth of natural granite and quartzite, which a printed surface cannot fake.
Step 4: Check the slab in natural daylight if at all possible
Warehouse metal-halide and fluorescent lighting distorts stone color badly, usually pushing whites toward green or blue and flattening warm undertones. Many Portland-area yards will let you carry a sample outside or roll a slab toward a bay door. Do it. Then hold your cabinet sample against it again.
Step 5: Look at the back and edges
The back of a natural stone slab tells you about mesh backing (common and normal on quartzite and marble, and a sign the material needed reinforcement) and about thickness consistency. The edges show you whether the color runs through the body or whether you are looking at a surface treatment.
Fissures vs. cracks — the distinction that matters most
This is where homeowners get scared unnecessarily, and occasionally where they miss something real.
A fissure is a natural separation along crystal boundaries. It is visible as a line, often feels slightly recessed to a fingernail, does not go through the slab, and does not compromise strength. Fissures are normal, expected, and present in nearly all granite and quartzite. They are a characteristic, not a defect.
A crack passes through the full thickness of the slab. You can usually confirm it by having someone shine a light on the opposite side, or by seeing the line continue on the back. A crack in a location that will be fabricated out is often a non-issue; a crack running through your future sink cutout or island field is a reason to pick a different slab.
Resin and epoxy fill is standard industry practice on natural stone with fissures or pits. Well-executed fill is nearly invisible and permanent. Look for it, ask about it, but do not treat it as a red flag.
Run your palm flat across the whole surface. Your hand finds texture changes your eye misses. Anything that catches a fingernail sharply is worth asking about — not necessarily a dealbreaker, but worth a conversation about where it lands in the layout.
Plan Your Seams and Layout Before You Approve the Slab
A slab is a raw material; your countertop is a layout. The gap between those two things is where great fabricators earn their money and where cheap ones create regrets.
Seams are inevitable in most kitchens. Any run longer than about 10 feet, most L-shaped configurations, and virtually every large island will need at least one. The question is never “can we avoid seams” but “where do we put them.” Good seam placement principles:
Put seams where the eye does not naturally rest — behind a faucet, at an inside corner, near a wall termination rather than mid-field.
Never run a seam through a sink cutout or a cooktop cutout if it can be avoided. Those are the highest-stress zones in the whole top.
On a veined stone, the veining should flow through the seam. This is called vein matching, and it is the difference between a seam you notice and one you have to hunt for. It costs material yield — sometimes an extra slab — and it is worth asking whether your quote includes it.
Ask to see a digital layout. A shop with a CNC and digital templating can show you exactly where every piece falls on the actual photographed slab, before a single cut. If your fabricator cannot produce this, you are approving a layout on faith.
Think about what will be covered. This is the most common regret we hear. A homeowner picks a slab for one gorgeous concentration of movement — and in the finished kitchen that area sits under the range, behind the sink, or inside the cabinet run. Before approving, get a rough sense of where your sink, cooktop, and any appliance cutouts land on the slab. Then move the dramatic zone to where you will actually see it: the island field, the visible run under a window, the waterfall panel.
Consider your edge at selection time. The edge profile changes how the stone reads. A thick mitered edge shows a lot of the pattern in cross-section and makes a slab feel monumental. A simple eased edge on 3cm reads clean and modern. On a heavily veined marble-look stone, a busy decorative edge like an ogee can fight the pattern. Look at edge samples in the same material family before deciding.
Finish changes the stone as much as the pattern does. Polished maximizes depth, color saturation, and stain resistance, and shows fingerprints and water spots more. Honed reads soft and matte, hides fingerprints beautifully, and on darker stones can show oils more readily. Leathered adds low-sheen texture that is excellent at hiding everything and is a favorite for busy Portland family kitchens. The same slab in three finishes looks like three different materials — always ask to see finish samples in the stone you are considering, not a generic finish board.
The 45 Minutes That Decide How Your Kitchen Looks for 20 Years
Most Portland homeowners spend weeks agonizing over quartz versus granite, then walk into a slab yard and pick their actual stone in under an hour. That is backwards. The material category matters, but the specific slab you approve — that individual piece, from that individual block, with that individual pattern — is what you will look at every single morning for the next two decades.
At Alpine Stones we walk customers through slab selection several times a week, and the same avoidable regrets come up again and again. Someone falls in love with a dramatic vein that ends up buried under the cooktop. Someone approves a slab under fluorescent warehouse lighting and is surprised by how gray it reads in a north-facing Portland kitchen in February. Someone chooses a stone from a 4-inch sample and never sees the full slab until it is installed. None of those are material problems. They are selection process problems.
This guide is what we would tell a friend before their first slab yard visit anywhere in the Portland metro or Vancouver WA. It covers how to actually read a slab, the difference between a cosmetic fissure and a structural crack, how lots and bundles work and why that determines whether your island and perimeter will match, how to plan seams before you commit, and how lighting and finish change everything. Bring it with you.

Questions to Ask, and Red Flags to Walk Away From
By the time you approve a slab you should have clear answers to all of these. If a shop is vague on any of them, that vagueness usually shows up later as a change order.
Ask about the stone
What is this material technically — granite, quartzite, marble, dolomitic marble, or engineered quartz? (Soft “quartzite” that is actually marble is a real and common mislabel, and it etches with lemon juice. Ask for an acid test on an offcut if you are unsure.)
What lot is it from, how many slabs remain, and will my slabs be tagged and held?
Does it need sealing, and how often in our climate?
Is there mesh backing or significant resin fill, and where?
Ask about the quote
Is this all-inclusive — templating, fabrication, edge profile, all cutouts, delivery, and installation?
What edge profile is included, and what does an upgrade cost per linear foot?
Are sink and cooktop cutouts included? Is the sink itself included?
Is plumbing disconnect and reconnect included? Old countertop removal and disposal?
Is vein matching across seams included, and will you show me the digital layout before cutting?
Who is liable if a slab breaks in fabrication or transit?
Ask about the company
Are you licensed and insured in Oregon, and what is your CCB number?
Do you fabricate in-house or subcontract it out?
What is your warranty on fabrication and installation, separate from the material warranty?
What is the realistic timeline from template to install?
Red flags
“Starting at” pricing with no written all-inclusive number. The gap between the teaser price and the final invoice is where the margin hides.
Refusing to name the lot or hold your slabs. This almost always means substitution is planned.
No digital layout, no template visit, or a quote produced entirely from your own measurements. Every real installation is templated on site.
Pressure to decide today because “this slab won’t last.” Sometimes true, usually a close.
No Oregon CCB license number. You can verify any contractor instantly on the Oregon CCB website. Do it.
A bid dramatically below every other bid. In fabrication, that gap is made up somewhere — thinner material, no vein matching, seams placed for yield instead of appearance, or corners cut on support and installation.
At Alpine Stones we fabricate in-house at our Portland facility on CNC equipment, we tag and hold your specific slabs by lot, we show you the digital layout on photographs of your actual slabs before we cut, and we quote one all-inclusive number. We are licensed in Oregon under CCB# 223660. If we break material, that is our cost, not yours.

Seams are inevitable in most kitchens. Any run longer than about 10 feet, most L-shaped configurations, and virtually every large island will need at least one. The question is never “can we avoid seams” but “where do we put them.” Good seam placement principles:
