Our team provides matching side and back splashes cut from the same remnant, delivering bathroom countertops that look planned rather than patched for both residential and commercial projects. We template on your installed vanity cabinet rather than a catalogue size, and the same crew that measures it comes back to set the top.
From centering two sink openings on a double vanity's cabinet lines to sealing the side splash tight to the wall, our team handles every detail. Serving Rancho Cucamonga plus bathrooms in Chino, Eastvale and San Dimas, we turn a small piece of good stone into a finished vanity with very little waste.

A bathroom vanity top in Rancho Cucamonga can usually be cut from a remnant, the leftover piece of a slab after a kitchen has been cut from it, and remnants are commonly priced roughly 30 to 70 percent below full slab pricing in national buying guides. A single vanity needs a piece only a little larger than 2 feet by 3 feet, which is exactly the size a kitchen job tends to leave behind. That makes a vanity the one place in a house where a premium granite or quartz costs about the same as a plain one: you are buying what is left, not a slab.
It cannot be ordered. Remnant stock changes weekly. You choose from what exists when you are ready, so a specific colour may not be there. It has a size limit. A wide double vanity often needs more stone than any remnant holds, and that job moves to a full or shared slab. Matching is by piece. Two bathrooms can be cut from one remnant only if it is big enough for both, so decide early if you want them to match.
If your kitchen is being cut at the same time, the vanity can come from the offcut of your own slab. The layout for the kitchen is drawn first, and the bathroom piece is planned into what is left, so nothing is wasted and the stone matches. Flippers and landlords updating several bathrooms at once can have each vanity measured on one visit and cut from whatever remnants fit, which keeps the cost per bathroom down.
Standard stock vanity tops come in 25, 31, 37, 49 and 61 inch widths at 22 inches deep, sized to sit on 24, 30, 36, 48 and 60 inch cabinets with a small overhang. A custom stone top follows your actual cabinet instead, which matters most in older houses where the vanity was built in place.
Vessel sink setups sometimes use a shallower top, around 18 to 20 inches deep. Older built-in vanities, common in Rancho Cucamonga homes from the 1970s and 1980s, can be almost any width, may butt against a wall on one or both sides and may not be square to the wall at all.
Choose the sink and the faucet before the vanity top is cut, because the faucet hole count and spacing are drilled into the stone and cannot be moved afterwards. The three common layouts are a single hole, a 4 inch centerset and an 8 inch widespread.
Single hole. One hole for a one-piece faucet with its handle on the body. It can also sit over a three hole layout with a deck plate, but not the other way round. 4 inch centerset. Three holes with 4 inches from the centre of one outer hole to the centre of the other, spout and handles on one base. 8 inch widespread. Three separate pieces, most often 8 inches apart centre to centre, though widespread sets can run up to 16 inches.
Undermount. The bowl mounts to the underside of the stone with clips and silicone, and the opening edge is polished. Easiest to wipe clean. Drop-in or self-rimming. The bowl hangs by its rim over the cut hole. Simpler and forgiving of an older bowl you want to keep. Vessel. A free-standing basin that sits on top of the stone, with a single drain hole below and usually a taller faucet. Every inside corner of a sink opening is rounded, because a square corner is where stone cracks. Bring the sink, or at least its model number and paper template, to the measure.
A double vanity top needs two sink openings, each centred on its own sink cabinet's centre line as measured from the built cabinet, not from a drawing or a catalogue page. If the openings drift, the bowls sit off their drain lines and the doors below no longer line up with the sinks above.
That is why we take the measurements from the cabinet already in your bathroom. Drawers, false fronts and the plumbing rough-in in the wall decide where each bowl can go.
A Jack and Jill bathroom shared between two bedrooms often has two basins, and a primary bathroom beside the largest bedroom usually does too. Both are common places for a double top in the newer homes of Eastvale and the Etiwanda area.
A custom stone bathroom vanity top in Rancho Cucamonga is typically estimated at roughly $500 to $2,000, with remnant or full slab, width and the number of sink openings moving the price most. A single vanity from a remnant sits toward the low end; a wide double top from a full slab sits toward the top of the range.
National buying guides estimate an undermount sink opening at roughly $75 to $150 each and a faucet hole at roughly $20 to $40 each, which is why a double vanity with widespread faucets costs noticeably more than a single with a one hole faucet.
What moves the estimate:
Treat these numbers, the national guide figures included, as estimates for Rancho Cucamonga that are subject to change with remnant stock; the written quote after your measure sets the final price, based on the stone you choose and the openings you need.
Most stone vanity tops get a 4 inch back splash, and a side splash wherever the top meets a side wall, cut from the same remnant so the colour matches. The splash covers the joint where water runs down the wall, which is the spot a vanity top most often fails without one.
Plan the splash with the top. A remnant that fits the vanity may not have enough left for splashes, and it is better to know at the measure than after cutting.
The process
Four steps, and nothing is cut until you have approved the slab and the seam layout.
Homeowners book a free template visit. Contractors and builders send plans and a finish schedule for a bid.
You pick the material and the slab, and we mark where every seam will fall before it is approved.
We template on your installed cabinets, then cut, edge and polish the tops in the shop.
The same crew sets the tops, fits the sink, joins the seams and leaves the room clean.
Questions
Usually, yes. Most single vanities need a piece only a little bigger than 2 feet by 3 feet, which a remnant often covers. A wide double vanity may need a full or shared slab.
Stock tops run 25, 31, 37, 49 and 61 inches wide at 22 inches deep. A custom stone top is cut to your actual cabinet, which is useful for built-in or out-of-square vanities in older homes.
It depends on the faucet you buy: single hole, 4 inch centerset or 8 inch widespread. Pick the faucet before the measure, because the holes are drilled to it and cannot move later.
Yes. Each opening is centred on its own sink cabinet as measured on site, and any seam is placed between the bowls, away from the openings.
It helps a great deal. Bring the sink, or its model number and cutout template, so the opening is cut to the bowl you will actually install.
A custom stone vanity top is typically estimated at roughly $500 to $2,000 in Rancho Cucamonga, depending on remnant or slab, width, sink openings and splashes. That estimate is subject to change, and your written quote sets the final price.
Yes, if the vanity cabinet is sound and level. The old top and sink come off, the cabinet is checked and shimmed, and the new stone is set on it with its splashes.
Yes. We measure and install across Rancho Cucamonga and in Chino, Eastvale, San Dimas, Upland and the other cities on our service areas page. Call with the vanity width and a photo to book.
