Riverside Custom Countertops works as Riverside County's top-rated team in commercial countertop installation, working with property managers, general contractors and facility managers on apartment unit packages, tenant improvement break rooms, and restaurant bar tops. We handle projects from 3 break room counters on a single office floor to 10 apartment kitchens turned on a leasing schedule.
Our crews work occupied apartment communities, office suites and restaurants, phasing installs around residents, tenants and business hours so units stay rentable and doors stay open. Backed by 12 years in business, we have completed over 1,870 projects, from a single bar section to multi-unit packages, and property manager and builder references are available on request.
From the field takeoff and sample approval to the punch walk and closeout paperwork, our team handles the parts of a commercial job that decide whether it finishes on schedule. Serving Riverside and neighboring Corona, Eastvale and Norco, we hold the GC's schedule, work nights and weekends where the property requires it, and turn the work over ready for punch and inspection.
Send your plans, unit count and target dates, and we will schedule a site walk.
What you can hold us to
Our commercial work in Riverside runs from 3 break room counters to 10-unit apartment packages, sized to what one shop and two install crews can hold on a fixed schedule. Most unit kitchens on these jobs fall in the 30 to 45 sq ft range, which is how we built the per-unit number for Dana's 10 apartment kitchens. Bigger packages in Riverside, Corona or Eastvale are phased by building or by floor so each phase closes out on its own.
| Scope | Typical unit | Est. per-unit investment |
|---|---|---|
| Apartment kitchen turnover | Kitchen countertop replacement (30 to 45 sq ft) | Est. $2,100 to $4,800 per kitchen |
| Office break room or wet bar | Wet bar or home bar top | Est. $750 to $2,400 per bar top |
| Model or common-area island | Kitchen island top | Est. $1,600 to $3,400 per island top |
Apartment communities, office tenant spaces, restaurants and builders' spec homes make up most of our commercial work, from Norco to Chino Hills. Near the University of California, Riverside, student and workforce apartments turn units every summer, while Downtown Riverside around the Mission Inn carries restaurants and bars that cannot close for a day. Office parks in Corona and the Goodman Commerce Center in Eastvale bring break rooms and reception counters on tenant improvement schedules.

Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Commercial countertops in Riverside are typically budgeted per unit, with an estimated $2,100 to $4,800 per apartment kitchen and $750 to $2,400 per break room or bar top, and slab grade, cutouts and access move the number most. Volume helps when every unit in a Riverside or Eastvale building shares one slab color and the included eased edge, because templating and cutting run in batches.
| 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 |
| Wet bar or home bar top | Est. $750 to $2,400 per bar top | Est. 3 to 5 hours |
| Old countertop tear-out and haul-away | Est. $150 to $500 per project | Est. 2 to 5 hours |
On material alone, engineered quartz typically runs an estimated $65 to $145 per sq ft installed and granite an estimated $55 to $135, which is why most Riverside property managers standardize on one builder white quartz across a whole building.
These per-unit figures are budgetary estimates for Riverside and are subject to change. Your written quote, confirmed on bid from the plans, the specifications and the site walk, sets the final price and the install schedule, and it depends on the slab spec, the unit count and the access to each unit.

Kevin, Corona business park, Corona
Office tenant improvement with three break rooms on two floors
Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Kevin managed an office tenant improvement in a Corona business park with three break rooms on two floors and a fixed move-in date. We recommended installing after hours in the Corona business park, one floor per evening, so the office stayed open during the day. The white quartz tops for all 3 break room counters came in at an estimated $3,400 to $5,600 over an estimated 1 to 2 days of install time, and all three break rooms were finished before the tenant's move-in date.
A commercial countertop job runs in seven steps on every Woodcrest, Norco or Temescal Valley site, and the laser template only happens once the cabinets are set and signed off.

Occupied buildings get phased installs, with work set around residents, tenants and opening hours, the way we have run them for 12 years. Dana's 10 apartment kitchens near the University area in Riverside were templated two units at a time as they vacated, and Omar's honed black granite bar near the Mission Inn was installed after closing so it opened for lunch. On occupied Corona and Riverside jobs we cover floors, cut nothing indoors and haul old tops out the same day, an estimated 2 to 5 hours of tear-out per unit.
Quartz, granite and solid surface cover almost every commercial spec we bid in Riverside County, chosen for upkeep more than looks, and quartz is the one that never needs sealing.
| Material | Est. installed price | Why it gets specified |
|---|---|---|
| Engineered quartz | Est. $65 to $145 per sq ft | Never needs sealing, consistent color across units |
| Granite | Est. $55 to $135 per sq ft | Heat and sun tolerance for bars and patios |
| Solid surface | Est. $70 to $130 per sq ft | Integrated sinks and invisible seams |
| Porcelain and sintered stone | Est. $55 to $120 per sq ft | Thin, light and stain resistant |
California has tightened silica rules for engineered stone fabrication, so every quartz top on a Riverside job is cut wet in our shop, never dry cut on site.
Lead time on a commercial package is typically 1 to 3 weeks from laser template to install day for in-stock quartz and granite. We template each unit the day its cabinets are set, as we did for Greg's 6 new-build kitchens in Eastvale, so the stone schedule follows the builder or property manager.

Property managers and GCs choose us because the same crew that templates a unit in Riverside installs it, and the schedule we bid is the one we work to. Our owner still checks seam layouts before anything is cut, and every commercial top carries our 1-year workmanship warranty on seams, fit and sink mounting.
We take commercial work across a 35-mile radius of the Riverside shop, from Hunter Industrial Park and the Galleria at Tyler corridor to apartment communities around California Baptist University. Corona, Eastvale, Norco and Temescal Valley along Interstate 15 make up most of our out-of-city bids, and we also bid Woodcrest, Yorba Linda, Villa Park and Chino Hills packages. Homeowners can find the residential side of the business on our Riverside countertop home page.

Each commercial buyer has its own page: builders and GCs use countertop fabrication for contractors, property managers book apartment and multifamily countertops, owners of bars and dining rooms read restaurant and hospitality countertops, and office landlords plan tenant improvement countertops.
Our smallest commercial jobs are typically a single break room or bar top, estimated at $750 to $2,400, and the largest we bid are 10-unit apartment packages.
Yes, we bid from plans and specifications, then confirm every dimension with a digital laser template at the site visit, before any slab is cut.
Commercial work is priced per unit or per room, typically an estimated $2,100 to $4,800 per apartment kitchen, and your written bid sets the final price.
Most packages are typically installed 1 to 3 weeks after the first laser template, and we template as cabinets land.
Yes, we install after hours for offices and restaurants, as we did one floor per evening on the Corona break rooms.
Yes, we template and install units in pairs as they vacate, so no unit sits empty waiting on stone, as on the University area turnover in Riverside.
A lead installer runs every crew, with 2 to 3 installers per kitchen, 3 to 4 for waterfall islands, and our estimator stays the contact through closeout.
Every top carries a 1-year workmanship warranty on seams, fit and sink mounting, and quartz adds its maker's warranty, typically 10 years to lifetime.
Request a bid with your property type, unit count or square footage, your timeline and whether plans exist, and we will set up the site walk.
