How to Estimate a Kitchen Remodel: Cabinets, Countertops, Layout Changes, and Hidden Costs

Kitchens pack the most expensive trades and materials into a relatively small footprint. A 150-square-foot kitchen remodel routinely costs $30,000-80,000+ because it touches plumbing, electrical, HVAC (range hood venting), cabinetry (the single largest cost), countertops (the second largest), flooring, lighting, appliances, and finish work. Every one of those categories has a wide cost range depending on the client's choices. The fundamental challenge for estimators: the same kitchen can cost $25,000 or $100,000 depending on cabinet quality, countertop material, appliance brand, and whether the layout changes. A client who says they want a kitchen remodel has not told you nearly enough. Your first job is to define the scope — same layout or new layout? Stock cabinets or custom? Laminate counters or quartz? Builder-grade appliances or pro-series? Each answer moves the estimate dramatically. The most profitable kitchen remodel contractors are the ones who spend the most time on the estimate and scope meeting before any work begins. A thorough estimate protects you from scope creep and sets client expectations so there are no surprises at the 50% mark.

Cabinets typically represent 30-40% of the total kitchen remodel cost. Understanding the three tiers is essential for accurate estimating. Stock cabinets come in pre-set sizes (typically 3-inch increments), limited door styles, and a small range of finishes. They are manufactured in bulk and available quickly (1-2 weeks). Cost: $75-250 per linear foot installed, or roughly $5,000-15,000 for a typical kitchen. Brands like Hampton Bay (Home Depot) and Diamond NOW (Lowes) are stock. The trade-off: you fill gaps with filler strips, and the options are limited. Semi-custom cabinets offer more size flexibility, a wider range of door styles and finishes, and interior options (pull-out shelves, lazy Susans, spice racks). Lead times are 4-8 weeks. Cost: $150-500 per linear foot installed, or $15,000-30,000 for a typical kitchen. KraftMaid, Waypoint, and Yorktowne are in this tier. Most mid-range remodels land here. Custom cabinets are built to exact specifications — any size, any material, any configuration. Lead times are 8-16 weeks. Cost: $500-1,500+ per linear foot installed, or $30,000-80,000+. Custom is appropriate for unusual spaces, very specific design visions, or clients who want furniture-quality craftsmanship. When estimating, get the cabinet quote early — it anchors the entire budget. If the client picks $40,000 in custom cabinets, the rest of the estimate builds around that. If they pick $8,000 in stock cabinets, the budget has room for a nicer countertop or appliance package. ContractorIQ includes cabinet cost calculators based on kitchen dimensions and tier selection.

Countertops are the second largest material cost. Pricing is per square foot fabricated and installed, and the range is enormous. Laminate: $15-40/sqft installed. Durable, many patterns including convincing stone look-alikes, but lower perceived value. Good for rentals and budget remodels. Butcher block: $40-100/sqft installed. Warm, natural look but requires maintenance (oiling) and is vulnerable to water damage around sinks. Quartz (engineered stone): $60-150/sqft installed. The current market leader — consistent patterns, zero maintenance, non-porous. Silestone, Cambria, and Caesarstone are major brands. Granite: $50-200/sqft installed depending on the slab. Each piece is unique. Requires periodic sealing. Still popular but losing market share to quartz. Marble: $75-250/sqft installed. Beautiful but high-maintenance — etches from acid (lemon juice, vinegar, tomato sauce), stains, and scratches. Mostly used as an accent or on islands rather than full kitchen coverage. A typical kitchen has 30-50 square feet of countertop. At quartz pricing ($80/sqft mid-range), that is $2,400-4,000 for materials and installation including sink cutout and edge profile. Flooring costs $5-15/sqft installed for LVP (luxury vinyl plank, the most popular kitchen flooring in 2026), $8-20/sqft for porcelain tile, or $10-25/sqft for hardwood. A 150 sqft kitchen floor runs $750-3,750 depending on material. Appliance allowances vary wildly. A builder-grade package (range, refrigerator, dishwasher, microwave) runs $3,000-5,000. A mid-range package (Samsung, LG, KitchenAid) runs $5,000-10,000. A pro-series package (Viking, Wolf, Sub-Zero) runs $15,000-40,000+. Always present appliances as an allowance in your estimate — the client controls this variable.

A same-layout kitchen remodel (replacing cabinets, counters, and appliances in the same positions) is dramatically cheaper than a new-layout remodel. The reason: moving plumbing, electrical, and gas lines is expensive and invasive. Moving a sink means relocating drain and supply lines. If the move is less than 4 feet, it might cost $800-2,000 for plumbing rough-in. If the sink moves to an island, you are cutting concrete (on a slab) or running drain lines through floor joists (on a crawlspace), adding a vent (AAV or conventional), and potentially extending both hot and cold supply lines 10+ feet. Island sink plumbing alone can cost $2,000-5,000. Moving a gas range requires a licensed plumber (or gas fitter) to extend or relocate the gas line. This typically costs $500-1,500 but can be more if the line runs through finished spaces. Moving from gas to electric (or vice versa) requires both plumbing and electrical changes. Electrical for a kitchen remodel almost always requires new work regardless of layout. Current code (NEC 2023) requires: at least two 20-amp small appliance circuits for countertop receptacles, GFCI protection on all countertop outlets, a dedicated 20-amp circuit for the dishwasher, a dedicated circuit for the refrigerator, and a 40-50 amp circuit for an electric range. If the existing wiring does not meet code, it must be upgraded — this is not optional in a permitted remodel. Electrical rough-in for a kitchen remodel typically runs $2,000-5,000.
