What Is the Most Expensive Thing When Renovating a House?

Kitchen renovations cost the most money in home improvements. Average spending ranges from $27,000 to $71,000 per project. Kitchens need cabinets, countertops, appliances, plumbing, and electrical systems. All these components create high total costs.
Bathrooms rank second at $25,000 average. Home additions cost $125 to $250 per square foot. Structural changes add $20,000 to $80,000 to budgets. Labor makes up 30-50% of total renovation expenses across all project types.
Why Do Kitchen Renovations Cost the Most?
Kitchen renovations cost the most because they combine expensive materials with complex labor needs. Cabinets alone range from $2,000 to $28,000. Appliances add $5,750 to $11,500. Countertops cost $1,500 to $8,000. These three elements form the foundation of kitchen expenses before adding flooring, lighting, or wall treatments.
Labor accounts for 30-40% of total costs. Plumbers charge $45 to $200 per hour to install sinks, dishwashers, and gas lines. Electricians run new circuits for appliances and lighting. Cabinet installers need precision skills to hang units level and secure. Moving gas lines or water pipes increases expenses by thousands of dollars due to code requirements and inspection needs.
According to the National Kitchen & Bath Association's 2025 Kitchen Trends Report, the average total cost for a medium-size kitchen renovation reached $71,159 including materials and labor. Large kitchens averaged $137,228 for complete remodels. These figures reflect the complexity of coordinating multiple trades and managing high-value materials.
Cabinet Selection Drives Major Costs
Kitchen cabinets cost between $2,000 and $28,000 depending on type and quality. Stock cabinets from home improvement stores offer the lowest prices. Semi-custom cabinets allow some personalization in dimensions and finishes. Custom cabinets built specifically for your kitchen command premium prices but fit perfectly in unusual spaces.
Quality matters for durability. Cabinets hold heavy pots, dishes, and small appliances daily. Soft-close hinges prevent slamming. Dovetail drawer construction resists years of use. Solid wood costs more than particleboard but lasts decades longer. Cabinet selection often represents the single largest line item in kitchen budgets, consuming 35-40% of total project costs.
Semi-custom options provide good middle ground. Manufacturers offer standard sizes with upgraded materials and finishes. Installation takes less time than custom work. Lead times run shorter than fully custom pieces. Most homeowners find semi-custom cabinets deliver quality results without maximum expense.
Appliance Packages Add Significant Expenses
Kitchen appliances cost $5,750 to $11,500 for standard packages. Smart appliances with WiFi connectivity and touchscreen displays exceed $20,000 for complete sets. Basic refrigerators start at $575 for simple models. Professional-grade ranges reach $10,000 or more for commercial-style cooking power.
According to Houzz's 2024 Kitchen Trends Study, 54% of homeowners replace all appliances during renovations. Nearly half choose high-tech units with advanced features. Technology adds convenience but increases costs significantly. Built-in refrigerators cost double compared to freestanding models. Induction cooktops exceed gas range prices by 30-40%.
Energy efficiency ratings affect long-term costs. Energy Star appliances use less electricity and water. Lower utility bills offset higher purchase prices over time. Professional installation adds $200 to $500 per major appliance. Gas connections need licensed plumbers. Electrical upgrades may require new circuits.
Countertop Materials Range Widely in Price
Kitchen countertops cost $1,500 to $8,000 based on material choice and square footage. Laminate costs $15 to $40 per square foot installed. Granite runs $40 to $100 per square foot. Quartz ranges from $50 to $150 per square foot. Marble creates luxury looks at $50 to $200 per square foot but needs regular maintenance.
Material affects durability and maintenance needs. Granite resists heat from hot pans. Quartz never needs sealing unlike natural stone. Laminate scratches easier than solid surfaces. Butcher block adds warmth but requires oiling. Edge profiles increase costs - simple edges cost less than decorative ogee or waterfall designs.
Installation complexity changes final prices. L-shaped counters need fewer seams than U-shaped layouts. Cutouts for sinks and cooktops require precision work. Undermount sinks create clean looks but need more support. Backsplash height affects material quantities. Full-height backsplashes protect walls better but use more stone.
Flooring Withstands Heavy Kitchen Traffic
Kitchen flooring costs $23 to $35 per square foot for tile installation. Premium materials push prices to $50 per square foot. Vinyl plank flooring offers budget options at $3 to $8 per square foot. Hardwood creates traditional looks at $8 to $15 per square foot installed but water damage risks exist.
Kitchens see heavy foot traffic and frequent spills. Durable materials last longer despite higher initial costs. Tile resists water and cleans easily. Luxury vinyl plank mimics wood without moisture concerns. Cork provides comfort underfoot and natural antimicrobial properties. Heated floors add $8 to $12 per square foot but increase comfort in cold climates.
Subfloor preparation affects total costs. Uneven floors need leveling compound. Old tile removal adds disposal fees. Transition strips between rooms create finished appearances. Grout sealing protects tile floors from stains. Professional installation prevents lippage and crooked lines that diminish appearance.
