From the acid test on a quartzite sample chip to the bookmatched miter on a waterfall drop, our team handles every detail. Serving Riverside and neighboring Norco, Corona, Eastvale, Yorba Linda and Temescal Valley, we keep a written record of every job, and six of them are laid out below.

Dana, University area, Riverside
Unit turnover package for a property manager, units vacated two at a time
What we recommended: Template each pair of units the day they vacate and install a week later, so no unit sat empty waiting on stone
The result: All 10 units turned on the property manager's leasing schedule
Ray, Sierra Bella, Corona
Backyard BBQ island where an old tile top had cracked in the sun
What we recommended: Leathered granite, which stays cooler to the touch and hides water spots outdoors
The result: A one-piece top over the grill cutout, no grout to crack
Tom, Horsetown USA ranch home, Norco
Long ranch kitchen with two corners and a 1980s laminate top
What we recommended: Place both seams over cabinet partitions, away from the sink and the cooktop
The result: Seams that sit where nobody leans, sealed granite throughout
Marcus, Eastvale home built 2000 or later, Eastvale
Tile backsplash with grease-stained grout behind the range
What we recommended: One slab from the counter to the hood, with outlet cutouts templated on site
The result: A wipe-clean range wall with no grout lines
Carol, a horse-property lot near the Richard Nixon Presidential Library, Yorba Linda
Remodel where the island was the centerpiece of an open plan
What we recommended: Bookmatch the two drops so the veining mirrors on both ends
The result: A mirrored vein pattern on both waterfall sides
Nancy, Trilogy at Glen Ivy, Temescal Valley
Single-story home where the owner wanted no sink rim to clean
What we recommended: Solid surface with an integrated sink and no seams at the sink
The result: A smooth top with a sink that wipes straight in

Dana manages an apartment community near the University area of Riverside, and her units were vacating two at a time. She needed 10 apartment kitchens in builder white quartz without any unit sitting empty while it waited on stone. We recommended templating each pair of units the day they vacated and installing a week later, so the stone kept pace with move-outs. The package was an estimated $24,500 to $38,000 and ran an estimated 10 to 20 days of install time across the turnover. Result: all 10 units turned on the property manager's leasing schedule.
Carol lives on a horse-property lot near the Richard Nixon Presidential Library, and her remodel made the island the centerpiece of an open plan. She chose Taj Mahal quartzite for an island with 2 waterfall sides. Our recommendation was to bookmatch the two drops so the veining mirrors on both ends, cut from consecutive slabs. Her project came in at an estimated $2,600 to $3,500 and took an estimated 6 to 8 hours on site. The finished island shows a mirrored vein pattern on both waterfall sides, the detail she had asked about at the first visit.
Ray had a backyard BBQ island in Sierra Bella where an old tile top had cracked in the sun. For his 11 ft BBQ island we suggested leathered Absolute Black granite, which stays cooler to the touch and hides water spots outdoors. That outdoor job was estimated at $2,000 to $2,700 and typically needs an estimated 1 to 2 days, including the grill cutout. He now has a one-piece top over the grill cutout, with no grout left to crack.
Marcus owns an Eastvale home built 2000 or later, where a tile backsplash had grease-stained grout behind the range. He wanted quartz matching the counters to run from the range wall to the hood. We templated outlet cutouts on site and cut one slab from the counter to the hood. The backsplash was an estimated $1,900 to $2,700 job over an estimated 1 to 2 days. Today he wipes down a range wall with no grout lines at all.
Tom lives in a Horsetown USA ranch home with a long kitchen, two corners and a 1980s laminate top. For his 45 sq ft ranch kitchen in Colonial White granite, we placed both seams over cabinet partitions, away from the sink and the cooktop. The kitchen was an estimated $3,600 to $4,600 and took an estimated 1 to 2 days to set and seal. His seams sit where nobody leans, and the granite is sealed throughout.
Nancy lives in a single-story home in Trilogy at Glen Ivy and wanted no sink rim to clean. We recommended solid surface with an integrated sink, joined so no seam falls at the bowl. Her 34 sq ft kitchen ran an estimated $2,600 to $3,400 and typically takes an estimated 1 to 2 days to install. The result is a smooth top with a sink she wipes straight into.
Most countertop projects on this page fell inside the estimated job ranges below, and the slab, the size and the number of cutouts moved each one. The table lists the job types we quote most often, with estimated investment and estimated time on site.
| Job type | Est. investment | Est. duration on site |
|---|---|---|
| Kitchen countertop replacement (30 to 45 sq ft) | Est. $2,100 to $4,800 per kitchen | Est. 1 to 2 days |
| Kitchen island top | Est. $1,600 to $3,400 per island top | Est. 3 to 6 hours |
| Waterfall edge drop | Est. $800 to $1,800 added per waterfall side | Est. 4 to 8 hours |
| Full-height slab backsplash | Est. $600 to $3,000 per backsplash | Est. 1 to 2 days |
| Outdoor kitchen granite tops | Est. $1,400 to $2,800 per outdoor kitchen | Est. 1 to 2 days |
| Wet bar or home bar top | Est. $750 to $2,400 per bar top | Est. 3 to 5 hours |
An apartment or builder package is priced per kitchen, so a 6 new-build kitchens order in Eastvale was estimated at $14,000 to $24,000 in total. Every project is typically installed 1 to 3 weeks after the laser template.
Prices on this page are estimates for Riverside and nearby cities and are subject to change. The written quote after your laser template sets the final price and the install schedule, and it depends on the slab, the square footage and the cutouts your project needs.
The stone in each case study came from the job, not the showroom: sun, use and upkeep decided it. Outdoor tops in Corona and Norco went granite because quartz resin can fade in direct sun, while indoor kitchens that wanted no sealing schedule went quartz.
| Material | Est. installed price | Where it worked in these projects |
|---|---|---|
| Engineered quartz | Est. $65 to $145 per sq ft | Dana's apartments, Marcus's range wall |
| Granite | Est. $55 to $135 per sq ft | Ray's BBQ island, Tom's ranch kitchen |
| Natural quartzite | Est. $85 to $185 per sq ft | Carol's waterfall island |
| Solid surface | Est. $70 to $130 per sq ft | Nancy's integrated sink kitchen |
Quartzite always gets an acid test on a sample chip first, which is how Steve in east Yorba Linda confirmed his Sea Pearl quartzite would not etch before we cut it.
Below the case studies, our galleries group the finished photos by the service behind them. Browse quartz slab countertop projects, granite slab kitchen installs, waterfall edge islands, outdoor kitchen and BBQ tops, full-height slab backsplash walls and apartment and multifamily packages. Each gallery shows the material, the room and the edge, so you can point at the look you want during your estimate.
A project record with names, neighborhoods and estimated numbers is easier to trust than a page of adjectives. Every job here was laser templated before cutting, set by a crew of 2 to 3 installers, and covered by our 1-year workmanship warranty on seams, fit and sink mounting. Our owner checks each seam layout before the saw starts, and you can meet the team who built these projects.
We take on projects across a 35-mile radius of our Riverside shop, from Canyon Crest and Orangecrest kitchens to Corona countertop projects, Norco ranch kitchens, Eastvale kitchen upgrades and Yorba Linda quartzite work. Woodcrest, Villa Park, Chino Hills and Temescal Valley are on our full countertop service area list.
