The Order Cabinets, Countertops and Backsplash Go In

Twelve cabinet boxes arrive on a pallet, and the countertop cannot be measured until every one of them is screwed to the wall and leveled, as the sequence at kitchen renovation riverside shopping the musical spells out for a kitchen in Riverside, CA. A stone fabricator will not cut a slab from a drawing alone.
Flooring comes before or after cabinets

Many installers set tile or plank flooring across the whole room and then build the cabinets on top of it, which makes a future floor change harder. Others run flooring only to the cabinet edges. The choice depends on the material and on whether the floor will ever be replaced. In Riverside County, where slab floors are common, moisture checks on the concrete come first.
Cabinet installation

Upper cabinets usually go up first, supported on temporary ledgers, then the base cabinets are shimmed to a level line. Fillers and end panels close the gaps against walls that are rarely square, a common condition in homes built near the Box Springs Mountains decades ago.
Templating the countertop
A fabricator visits after the cabinets are fixed, measures every edge and marks the sink and cooktop cutouts. Fabrication takes days to weeks depending on the material and the shop schedule. During that gap the kitchen has no counters, so the temporary setup stays in place.
Backsplash
Tile goes up after the countertop, because the tile has to meet the stone or laminate edge cleanly. Outlet boxes get extended forward so they sit flush with the finished wall surface. Grout needs a day to cure before sealing and cleanup.
Lighting and final connections
The lighting plan finishes the job. Under cabinet lights, pendants over an island and recessed fixtures are wired to switches placed during rough-in. The plumber returns to set the faucet, disposal and dishwasher, and the electrician installs the fixtures and covers. Walking the room with a punch list, one item at a time, closes out the project near the University of California Riverside side of town or anywhere else in Riverside.
Delays stack up between these steps, so a realistic schedule leaves a gap after cabinets for templating and another after the counter for the plumber to reconnect the sink. Skipping those gaps is the usual reason a kitchen sits unfinished for an extra week in Riverside.
Small items matter too. Toe kicks, crown, hardware and the panel that hides the dishwasher edge are installed last, once the counter is protected, so nothing gets scratched by the trades that come after.
