What Is in the StoneX USA Slab Warehouse
The live inventory above reads from our warehouse system in real time. Below is what that inventory covers, so you know what to expect before you drive to West Allis. Every color listed here has its own page with specifications, care notes and photographs of the actual material.
| Material | Colors stocked | Best known for |
|---|---|---|
| Engineered quartz | 100+ | Consistent pattern slab to slab, non-porous, never needs sealing |
| Granite | 28 | Natural one-of-a-kind movement, heat and UV tolerant, outdoor-capable |
| Porcelain | 16 | Large format, scratch and heat resistant, outdoor-rated, zero maintenance |
| Quartzite | 15 | Marble looks with granite-level hardness and etch resistance |
| Marble | 3 | Classic veining for baths, fireplaces and feature surfaces |
| Soapstone | 2 | Naturally non-porous and acid-proof; never needs a sealer |

Browse by color family
Our stocked colors skew toward whites and neutrals: roughly 32 white, 22 black, 19 gold, 8 blue, 6 brown, 5 gray and 4 green colors across all materials. Popular starting points are the calacatta looks, white quartz and black quartz collections, and the full Legacy Quartz range.
Browse by finish
Slabs are stocked in polished (the largest share), honed and leathered finishes. Polished reflects light and deepens color; honed is matte and soft; leathered adds a gentle texture that hides fingerprints and glare. Many colors are stocked in more than one finish - compare Taj Mahal Polished, Honed and Leathered Quartzite to see the difference.
How Buying from the Warehouse Works
1) Shortlist colors here or on the material pages. 2) Visit the West Allis slab gallery at 1735 S 106th St - open Monday to Friday 8:30-5:00 and Saturday 8:30-2:00 - and tag your exact slab. 3) A vetted fabricator partner collects it, templates and installs. Builders, remodelers and fabricators buy on trade terms; request a quote or call 414-998-0404. Coming from out of town? See our guides for Waukesha, Brookfield and Kenosha.
Live Inventory Questions
What does StoneX USA keep in stock?
Full slabs across seven material families: engineered quartz, granite, quartzite, porcelain, marble, soapstone and onyx. Every color has its own page with specifications, and every slab shown in the live inventory is physically on the racks in West Allis, WI.
How current is the live inventory?
It reads directly from the warehouse inventory system, so it reflects what is actually on the racks rather than a printed list. Slabs move quickly, so tag the ones you want when you visit.
Can I reserve or tag a slab before I buy?
Yes. Visit the West Allis slab gallery, walk the racks and tag the exact slab you want. Your fabricator then collects it - the piece you tagged is the piece that gets fabricated.
Do I need a fabricator to buy slabs?
Homeowners are welcome to browse and tag slabs; fabrication is handled by a shop. StoneX USA maintains a directory of vetted fabricator partners across Wisconsin and Illinois, and also sells directly to fabricators, builders and remodelers on trade terms.

Who We Supply
StoneX USA is a slab supplier at 1735 S 106th St, West Allis, WI — one location, about ten minutes from downtown Milwaukee. What you need from us depends on which side of the job you are on:
Fabricators and countertop shops
Buy single slabs or whole bundles — there is no bundle minimum. Walk the rack, pick the exact slab, and take it the same day. We supply the stone; we do not fabricate or install, so we are not competing with your shop.
Builders and remodelers
Spec from what is physically on the floor in West Allis rather than from a catalogue, and ask us to hold a lot while a job is being scheduled. One location means one phone call to confirm what is actually available.
Architects and designers
Bring the drawing and see full slabs rather than four-inch chips — movement, veining and colour only read correctly at slab scale. We can confirm how many slabs of a lot are on the floor before you specify it.
General and commercial contractors
For runs that need lot consistency across floors or units, ask for bundle quantity and lot numbers up front. Lead time and freight usually decide a commercial stone budget more than the material itself.
