A Precast Concrete Patio Bar in Temescal Valley
Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Luis wanted a covered patio bar beside a pool at his home near Glen Ivy Hot Springs, and he wanted the top to match the patio rather than look like a kitchen counter. We recommended sealed concrete, a precast top protected against pool water and sunscreen, cast in one piece in our shop so it arrived fully cured. The 16 sq ft patio bar was an estimated $1,200 to $1,900 job and took an estimated 3 to 5 hours to set on site. The result is a one-piece concrete bar top that matches the patio.

Concrete Countertop Cost in Riverside
Custom concrete countertops in Riverside are estimated by the job, and most bar tops typically run an estimated $750 to $2,400 while a covered patio bar like the one in Temescal Valley came in at an estimated $1,200 to $1,900. Size, integral color, the finish and any cast-in sink move the price most.
A standard 30 to 45 sq ft kitchen in precast concrete is typically estimated at $2,100 to $4,800, with long runs that need more seams sitting toward the top of that band. Outdoor kitchens on a block BBQ island are typically estimated at $1,400 to $2,800, and removing an old tile or laminate top is typically estimated at $150 to $500 on a replacement job.
The concrete numbers above are Riverside estimates and could change with material costs. Your written quote after the template sets the final price and the install schedule, and it depends on the casting method, the color and finish and whether the sink is cast into the top.
Precast vs Cast-in-Place Concrete Countertops
Precast concrete is poured and cured in a shop from a site template and then installed, while cast-in-place concrete is formed and poured directly on top of your cabinets. Most of our Riverside concrete work is precast, because shop conditions control the mix, the curing and the finish far better than a kitchen does.
| Method | Where it is made | Seams | Crack and finish control | Best for |
|---|---|---|---|---|
| Precast concrete | Our Riverside shop, from a laser template | Seams where sections meet | Controlled curing, finish checked before delivery | Kitchens, bar tops, islands that can be carried in |
| Cast-in-place concrete | Poured on your cabinets | No seams | Weather and site drying affect the cure | Long or awkward runs that cannot be carried |
| Granite slab | Quarried stone, cut in our shop | Hairline epoxy seams | No curing, sealed at install | Owners who want stone, not concrete |
Cast-in-place avoids seams but brings wet work, forms and drying time into your home. Precast arrives finished and sealed, so the kitchen is usable sooner, which is why Luis's Temescal Valley bar went precast.
Concrete Countertop Cracking and Sealing Risks
Hairline cracks are the main risk with concrete, and most start in the first three days of curing, when fast drying pulls on concrete that has not gained strength yet. Concrete typically reaches over 90 percent of its final strength within about four weeks, so a top that cures too fast, or carries weight too soon, is the one that cracks.
We limit cracking with steel reinforcement, fibers in the mix and slow, damp curing in the shop, never in a hot Riverside garage during Santa Ana winds. A fine hairline crack in a concrete top is usually cosmetic and part of the material's character, but a crack that opens is a structural problem, which is why reinforcement is never skipped.
Sealing is the second risk. Concrete is porous, so an unsealed top stains from oil, wine and citrus; we seal every top before it leaves the shop, and most owners reseal about once a year. Outdoors, a sealer also protects the top from pool water and sunscreen, as on the Temescal Valley patio bar.
Why Homeowners Bring Concrete Projects to Us
Concrete rewards a shop that has cast it before, and our crew has been setting heavy, custom tops for 12 years in business. The same crew that templates your layout sets the finished top, and every install carries our 1-year workmanship warranty on seams, fit and sink mounting. Meet the team behind our Riverside shop.
Other Countertop Materials We Install
If concrete's upkeep is not for you, compare granite countertops for outdoor and indoor kitchens, low-care quartz countertops or seamless solid surface tops. Granite typically runs $55 to $135 per sq ft installed and needs no curing at all.

Concrete Countertop Questions From Riverside Homeowners
How much do concrete countertops cost in Riverside?
Most concrete bar tops are typically estimated at $750 to $2,400, and your written quote sets the final price after the template.
Will my concrete countertop crack?
Hairline cracks can appear in any concrete, but steel reinforcement, fibers and slow shop curing keep them small and cosmetic.
Is precast or cast-in-place better?
Precast is our standard because it cures in controlled shop conditions and arrives sealed, while cast-in-place suits runs that cannot be carried in.
How often do concrete countertops need sealing?
We seal every top before delivery, and most owners reseal about once a year, more often outdoors near a pool or on a dusty Eastvale patio.
How long does a concrete countertop take?
A precast top typically takes 1 to 3 weeks from template to install day, and a bar top like Luis's takes an estimated 3 to 5 hours to set.
Can concrete be used outdoors in Riverside?
Yes, a sealed concrete top handles shade and covered patios well, and fully sun-exposed outdoor kitchens in Norco often go granite instead.
Can you cast a sink into a concrete countertop?
Yes, an integral concrete sink can be cast with the top, or we mount an undermount sink with clips and epoxy, as on most Chino Hills and Villa Park kitchens we template.
