Undermount basins
An undermount basin hangs below the stone, so the edge of the opening is on show and is polished smooth rather than left rough. The basin is fixed to the underside and sealed with silicone.

Our team provides remnant sourcing from the offcuts left after full kitchen countertop jobs, delivering a stone countertop sized to a small bath and repeat pricing for flippers and rental owners, for both residential and commercial projects. We lay out the basin, the faucet holes and any seam on your chosen remnant, and you approve that layout before a single cut is made in our shop.
From the polished radius inside an undermount basin opening to the side splash that closes the gap against a tiled wall, our team handles every detail. Serving Asheville, Fairview and Black Mountain, we fit vanity tops to hall baths, primary suites and rental units alike.
Why Buncombe Custom Countertops
The crew that measures your kitchen is the crew that sets the tops.
A remnant is the usable piece of stone left over when a full slab is cut for a larger job, and it is often big enough for a vanity. A typical single vanity needs far less stone than a kitchen, so buying a whole slab for one bathroom means paying for material that never leaves the shop.
Remnant stock changes from week to week. Bring your vanity size to the call and we will tell you what fits.
The basin and the faucet are picked before the stone is cut, because the openings are made to those exact fixtures and cannot be moved afterwards. Bring both, or their model numbers, to the measure.
An undermount basin hangs below the stone, so the edge of the opening is on show and is polished smooth rather than left rough. The basin is fixed to the underside and sealed with silicone.
A drop-in, or self-rimming, basin is held by its own rim, which sits on the top and is sealed. The rim covers the cut edge, which can suit an older bathroom or a tighter budget.
A vessel sink is a free-standing bowl finished on all sides that sits on the surface. The top needs only a drain hole and the faucet holes, and the faucet is usually taller or wall-mounted.
A single-hole faucet needs one hole; a three-piece faucet needs three, spaced to that faucet. We drill to the fixture you bring, so changing faucets later can mean a new top.
A solid surface top can have a basin of the same material glued to its underside and sanded flat, which leaves a joint you can barely see.
A double vanity may need a seam when it is longer than the largest remnant that suits it. Where there is a seam, it is planned on the stone before cutting and kept well clear of both basins. EuroStone's quartz guide keeps a joint at least 12 inches from any cutout, so on a double vanity the seam usually falls in the space between the two sinks.
The edge profile and the splash finish a vanity top, and both are decided at the measure along with the basin. A simple eased or bevelled edge suits a small remnant, because a thick built-up edge needs extra stone that a remnant may not have.
If a remnant is too small for the top and its splashes, we tell you before cutting and suggest a plain painted or tiled wall instead.

Bathroom surfaces take splashed water and warm humid air that condenses on cold surfaces, so the top needs to shed water and clean easily. Quartz and sealed granite both do that well at vanity height. Natural stone takes an impregnating sealer that newer products need reapplied about once every five to ten years on most materials. Marble is softer and etches from acids, so it needs gentler cleaners, and we say so before you choose it for a busy family bath. The seal around the basin and along the back wall matters as much as the stone, because that joint is where water tries to get into the cabinet below.
A remnant vanity top usually moves faster than a kitchen, because the stone is already on hand and there is no slab to order. The measure fixes the dates, and they are written on your quote. For the day itself, a licensed plumber disconnects the old sink and faucet before we arrive, we remove the old top if needed and set the new one, and the plumber reconnects the water and drain afterwards. North Carolina licenses plumbing work separately, so we do the stone and your plumber does the pipes. If the vanity cabinet itself is being replaced, it has to be installed and level before we measure.
Flippers, landlords and remodelers with several bathrooms can order vanity tops in batches. Send the vanity sizes, basin models and faucet type for each unit and we can match remnants across them, measure the baths in one visit, and set installs around your other trades or a tenant change.

A stone vanity top in Asheville is typically estimated at roughly $500 to $2,000, with remnant versus full slab and the number of basins moving the price most. That range is a service-ticket bank estimate for vanity work, not a quote.
All of these numbers are estimates and are subject to change with remnant stock and site conditions. The final price is set in your written quote after the free measure.
Drag the handle. The cabinets stayed; only the top changed.

BeforeAfter
BeforeAfterThe process
We come to the house, look at the cabinets, the walls and the way in from the driveway, and talk through materials and edges.
You get the slab, the edge, the cutouts, the seam plan and the dates in writing. Nothing is cut until you sign off.
Once the cabinets are set and level, we template them, then cut and finish the tops in the shop to that template.
We set and join the tops, then walk the finished kitchen with you before we call it done.
Questions
Yes. Most single vanities can be cut from a quartz or granite remnant, and larger or matching tops can come from a full slab. We measure the cabinet first.
Usually, because you pay for a smaller piece rather than a slab you only partly use. Your written quote shows the price for the remnant you choose.
Yes, or at least the model numbers. The basin opening and faucet holes are cut to those fixtures and cannot be moved later.
Only if it is longer than the stone available. When a seam is needed, it goes between the basins and is laid out on the stone with you before cutting.
Sometimes. If an offcut from your own kitchen slab was kept, it may cover a vanity; otherwise we look for a remnant of the same material, or price a top from a new slab of that color.
Yes. A vessel bowl sits on the stone, so the top needs only a drain hole and the faucet holes for the tall or wall-mounted faucet you choose.
A licensed plumber disconnects and reconnects them. We cut the openings and set the top and basin.
Yes, if the cabinet is solid, level and dry. A vanity base with a swollen or soft floor from an old leak should be replaced first.
A stone vanity top is typically estimated at roughly $500 to $2,000, depending on size, basins and whether it comes from a remnant. Your written quote sets the final price.
