Kitchen Cabinet Costs: Custom vs. Semi-Custom vs. RTA

Cabinets are the single largest cost driver in a kitchen remodel, typically accounting for 35–45% of total project cost. Understanding what you're actually getting at each price point — and why the gap between RTA and custom is so large — is the most important research you can do before buying. Here's a complete breakdown.

Kitchen Cabinet Cost by Type

Material cost only. Add 20–35% for professional installation. Infinity buys semi-custom cabinets factory-direct, which typically runs 20–30% below what you'd pay through a design showroom for equivalent quality.

What Each Tier Actually Gets You

Stock and Big-Box Cabinets ($75–$175/linear ft)

Stock cabinets are pre-built in fixed standard sizes — typically 3-inch increments from 9 to 36 inches wide — and sold directly from inventory at home improvement stores. You take what's on the shelf. Construction is typically 1/2-inch particleboard with a thermofoil or laminate finish, and the hardware is basic. The face frames are stapled together rather than mortised and glued.

These work fine for rental properties, garage workshops, or utility spaces where you need functional cabinetry fast. In a kitchen where longevity and appearance matter, stock cabinets are a compromise most homeowners regret within five years — particularly around the sink and dishwasher, where particleboard cores swell and delaminate once they get wet. If you're going to invest in a kitchen remodel, it's worth starting with a cabinet that will hold up for 15–20 years.

RTA (Ready-to-Assemble) Cabinets ($100–$225/linear ft)

RTA cabinets ship flat and are assembled on site. The quality range is wide — there are RTA brands using solid plywood boxes and dovetail drawer construction that rival semi-custom quality, and there are brands using particle board and staples that are little better than stock. RTA from a reputable manufacturer can be a legitimate value-play, but you need to specify what you're getting: plywood vs. particleboard box construction, drawer box material and joint type, drawer slide rating (full-extension, soft-close or not).

The main practical downside to RTA is that assembly quality varies with the installer, and lead times on replacement parts when something breaks are typically longer than with a semi-custom line that manufactures domestically. Infinity recommends RTA only when budget is the overriding priority and the homeowner understands the trade-offs clearly.

Semi-Custom Cabinets ($250–$500/linear ft) — The Sweet Spot

Semi-custom cabinets are built to order from a manufacturer's range of sizes, styles, finishes, and interior features. You have real choices: door style (shaker, inset, raised panel, slab), finish (paint, stain, specialty), box depth, height, and interior options (rollout trays, pull-out shelves, built-in organizers). Construction is solid — typically 3/4-inch plywood boxes, dovetail or dowel-jointed drawer boxes, full-extension soft-close drawer slides, and adjustable shelving.

For the vast majority of kitchen remodels, semi-custom is the right tier. You get real design flexibility, durable construction, and a finished product that will look and function well for 20+ years. Lead times run 3–8 weeks depending on manufacturer. This is where Infinity's factory-direct purchasing makes the biggest difference — we work directly with cabinet manufacturers, cutting out the showroom middleman and delivering semi-custom quality at pricing closer to RTA showroom prices.

Full Custom Cabinets ($500–$1,200+/linear ft)

Custom cabinets are built entirely to your specification by a local or regional cabinet shop — any size, any species, any finish, any detail. They're the right choice when your kitchen has non-standard dimensions that semi-custom doesn't accommodate, when you have a very specific aesthetic that isn't available in any manufacturer's line, or when you're building a showpiece kitchen where no compromise is acceptable.

The trade-offs: lead time is typically 8–16 weeks, cost is roughly double semi-custom at equivalent quality, and there's no manufacturer warranty — you're relying on the individual shop's workmanship. For most remodels, the jump from top-tier semi-custom to custom yields diminishing returns. The exception is a kitchen where every inch of space matters and off-the-shelf sizing creates compromises you can't work around.

Installation Cost: What to Add

Cabinet installation is a skilled trade — setting boxes plumb and level on an uneven floor, scribing filler pieces, fitting around corners and appliances, and hanging upper cabinets at precise heights all require experience. Budget $2,500–$6,000 for installation on a typical kitchen, or roughly 20–30% of the cabinet material cost. This includes hanging all boxes, installing doors and drawer fronts, adjusting hinges and slides, and attaching hardware. Countertop installation is separate.

Permits for Cabinet Projects in Avondale

Cabinets on their own don't need a building permit in Avondale: the city's code lists cabinets, countertops, tiling, and painting as exempt finish work. The permit question comes from what travels with the cabinets. Moving the sink, adding hardwired under-cabinet lighting or new circuits, or relocating a gas range is plumbing, electrical, or gas work, which is not exempt and needs a permit from the City of Avondale's Building Services Division, with inspections before the work is covered. We pull City of Avondale permits for our work. Our Avondale permit guide has the details.

One more local note: Avondale's water is very hard (city well water averaged about 21 grains per gallon in the city's 2022 water quality report), and that is tough on faucets, supply valves, and dishwasher connections. Because a slow leak under the sink is what usually ruins a cabinet box, it is worth choosing a plywood sink base at every tier and replacing old supply valves whenever the sink is reconnected.

Cabinet Upgrades That Add Cost

• Soft-close hinges and drawer slides: Usually standard on semi-custom; add $300–$700 to an RTA kitchen if not included.
• Interior rollout trays and organizers: $150–$600 for a full kitchen, depending on the number of roll-outs, pull-out trash drawers, and spice pull-outs.
• Under-cabinet lighting: LED strip lighting adds $400–$1,200 for a typical kitchen; requires an electrician for hardwired installation.
• Glass-front doors: $75–$150 per door additional for glass insert and routing.
• Crown molding and light rail: $300–$800 installed; finishes the top of upper cabinets to the ceiling and adds significant visual refinement.

How Infinity's Factory-Direct Pricing Works

Most homeowners buy semi-custom cabinets through a kitchen design showroom, which marks up manufacturer pricing by 25–40% to cover showroom overhead and sales commissions. Infinity purchases directly from cabinet manufacturers at contractor pricing and passes that savings directly to you. For a typical kitchen, this translates to $3,000–$7,000 in savings on cabinet materials alone — with no compromise on quality or selection. Learn more on our kitchen cabinets service page.

Frequently Asked Questions

How much do kitchen cabinets cost in Avondale, AZ?

Semi-custom kitchen cabinets — the right tier for most homeowners — run $250–$500 per linear foot for materials, or $10,000–$25,000 for a typical kitchen. Add 20–30% for professional installation. Infinity's factory-direct purchasing typically delivers semi-custom cabinets for 20–30% less than showroom pricing for equivalent quality.

Are RTA cabinets worth it?

From a quality-reputable manufacturer with plywood box construction and dovetail drawers, yes — especially for budget-constrained projects. From a budget supplier using particleboard and staples, no. The problem is that most homeowners can't easily tell the difference when shopping online. If you're considering RTA, let us evaluate the specific brand and product before committing — we've seen enough of both ends of the spectrum to give you an honest read.

How long does cabinet lead time take?

Stock cabinets are available immediately. RTA ships in 1–3 weeks from order. Semi-custom typically runs 4–8 weeks. Full custom from a local shop runs 8–16 weeks. We factor lead time into your project schedule during the planning phase — your cabinets should arrive before demo starts, not two weeks after.

Do I need a permit to replace kitchen cabinets in Avondale?

Not for the cabinets alone. The City of Avondale's building code lists cabinets, countertops, tiling and painting as finish work that needs no building permit. If the job also moves the sink, adds hardwired lighting or new circuits, or relocates a gas range, that plumbing, electrical or gas work is not exempt and needs a permit from the city's Building Services Division. We pull City of Avondale permits for our work. See our Avondale permit guide.
