Unit
A unit is a single item or piece used in construction pricing and material ordering, such as individual fixtures, doors, windows, or appliances.
What is a Unit?
A unit in construction terminology refers to a single item, piece, or component used in building projects. Units are individual items that are counted as whole pieces rather than measured by length, area, or volume.
Unit pricing simplifies estimating and billing for items that come as complete, individual pieces.
Common Items Priced by Unit
Fixtures and Hardware
- Light fixtures: Ceiling fans, chandeliers, recessed lights
- Plumbing fixtures: Toilets, sinks, faucets, shower heads
- Hardware: Door handles, hinges, cabinet pulls
- Outlets and switches: Electrical receptacles and controls
Building Components
- Doors: Interior doors, exterior doors, garage doors
- Windows: Individual window units of any size
- Skylights: Roof-mounted light units
- Vents: Exhaust fans, roof vents, soffit vents
Appliances and Equipment
- Kitchen appliances: Refrigerators, stoves, dishwashers

Unit vs. Other Measurements
Unit vs. Linear Foot
- Unit: Complete door ($200 per unit)
- Linear foot: Trim around door ($5 per linear foot)
Unit vs. Square Foot
- Unit: Window installation ($150 per unit)
- Square foot: Flooring ($8 per square foot)
Unit vs. Piece
These terms are often interchangeable in construction:
- "Install 5 units" = "Install 5 pieces"
- Both refer to individual, complete items
Unit Pricing Strategies
Labor Pricing per Unit
Many contractors use unit pricing for installation:
- Toilet installation: $150-$300 per unit
- Light fixture installation: $75-$200 per unit
- Door installation: $200-$500 per unit
- Window installation: $300-$800 per unit
Material Plus Labor
Complete unit pricing includes both materials and installation:
- Standard interior door: $300-$600 per unit installed
- Basic window: $400-$1,200 per unit installed
- Kitchen appliance: $200-$500 installation per unit
Benefits of Unit Pricing
For Contractors
Simplified Estimating: Easy to calculate total costs (units × price per unit) Clear Pricing: Clients understand exactly what they're paying for Standardized Rates: Consistent pricing across similar projects Easy Change Orders: Simple to add or remove units from projects
For Clients
Transparent Pricing: Clear cost per item installed Easy Comparisons: Can compare unit prices between contractors Budget Planning: Know exact costs for specific quantities Scope Clarity: Understand exactly what's included per unit
Factors Affecting Unit Pricing
Complexity of Installation
Standard installation: Basic unit pricing applies Complex installation: Premium pricing for difficult access or special requirements Custom work: Higher unit pricing for non-standard installations
Quantity Discounts
- Single units: Full retail pricing
- Multiple units: Bulk pricing may apply
- Large projects: Significant discounts for high quantities
Quality Levels
- Builder grade: Lower unit pricing
- Mid-range: Standard unit pricing
- Premium/custom: Higher unit pricing
Unit Pricing Applications
Electrical Work
- Outlet installation: $125-$200 per unit
- Switch installation: $100-$150 per unit
- Ceiling fan: $200-$400 per unit installed
- Recessed light: $150-$300 per unit installed
Plumbing Work
- Faucet replacement: $200-$400 per unit
- Toilet installation: $150-$350 per unit
- Sink installation: $300-$600 per unit
- Water heater: $1,200-$3,000 per unit installed
Carpentry Work
- Interior door: $200-$500 per unit installed
- Window installation: $300-$800 per unit
- Cabinet installation: $100-$300 per unit (depending on size)
Estimating with Units
Material Takeoff
- Count total units needed: List each type and quantity
- Research unit costs: Materials + installation for each type
- Calculate extensions: Units × cost per unit for each item
- Add markup: Include overhead and profit
Example Estimate
Bathroom renovation requiring:
- 1 toilet × $300 = $300
- 1 vanity × $600 = $600
- 1 shower fixture × $400 = $400
- 3 light fixtures × $150 = $450
- Total: $1,750 for fixtures and installation
Common Mistakes
Inconsistent Unit Definitions: Ensure all parties understand what's included in each "unit."
Not Specifying Quality: Unit prices vary significantly based on material quality.
Forgetting Complexity Factors: Standard unit pricing may not apply to difficult installations.
Missing Coordination: Some units require coordination with other trades (electrical, plumbing, etc.).
