The Bathroom Remodel Cost Calculator estimates typical installed costs for cosmetic refresh, partial remodel, and full gut projects across Basic, Midrange, and Upscale quality levels.

Formulas

BaseMaterials = Area × BaseMaterialsRate(quality) × ScopeMaterialsFactor(scope)
TileWalls = Area × TileCoverageFactor(option) × TileWallRate(quality)
Fixtures = Vanity(quality,type) + Toilet(quality) + BathingUnit(quality,option)
Extras = (HeatedFloor ? Area × HeatedFloorRate : 0)
Materials = (BaseMaterials + TileWalls + Fixtures + Extras) × Region
Labor = (Area × 55 × ScopeLaborFactor(scope) × QualityLaborFactor(quality) × Location) + (Area × DemolitionRate(scope))
Permit = (Materials + Labor) × 0.02
Total = (Materials + Labor + Permit) × 1.10

Key settings

  • Base materials/ft²: Basic $60, Midrange $100, Upscale $150
  • Tile wall/ft²: Basic $22, Midrange $30, Upscale $45
  • Tile coverage factors: None 0.0, Half-height 0.7, Full-height 1.4
  • Fixtures bundles (by quality): Vanity (Single/Double), Toilet, Bathing Unit (Shower, Tub/Shower, Separate)
  • Heated floor: $12/ft² (optional)
  • Labor baseline: $55/ft² × scope × quality × location + demolition
  • Location factors: Rural 0.90, Suburban 1.00, Urban 1.15
  • Region factors: None 1.00, Northeast 1.10, Southeast 1.08, Midwest 1.07, West 1.11
  • Permit: 2% of materials + labor
  • Contingency: 10% of subtotal

Example

60 ft² • Midrange • Partial remodel • Shower • Single vanity • Half-height tile • Location: Suburban • Region: None • Heated floor: No

Base materials $6,000.00 · Tile walls $1,260.00 · Fixtures $4,650.00 → Materials $11,910.00
Labor $3,795.00 → Permit $313.10 → Subtotal $16,018.10
Contingency (10%) $1,601.81Total $17,619.91 ($293.67/ft²)

Note: Values reflect typical mid-range pricing; actual costs vary by tile coverage, fixture brands, layout changes/relocation of plumbing, ventilation/electrical scope, and contractor demand.

What is a bathroom remodel?

A bathroom remodel refers to changes in a bathroom such as appearance, layout, function, or any major system. It can be as small as a paint or a few cosmetic updates, or as large as a full-gut remodel involving new walls, plumbing, or electrical work

What is a bathroom remodeling cost calculator?

A bathroom remodeling cost calculator gives you a quick way to estimate bathroom remodeling costs based on inputs such as bathroom area (ft²), quality level, project scope, tile wall coverage, and location. The calculator uses standard unit rates adjusted by region and current market conditions.

How is bathroom remodeling cost calculated?

The bathroom remodeling cost follows a simple formula to estimate the total cost and the unit price per ft². Let’s walk through a real-world example to see how it works:

Inputs data:

  • Area: 60 ft²
  • Quality: Midrange
  • Scope: Partial remodel
  • Tile walls: Half-height (wainscot)
  • Region: Not specified (no regional uplift)

Step-by-step calculations

  1. Materials base: 60 ft² × $100/ft² × scope factor (1.0) = $6,000
  2. Tile walls: coverage factor 0.7, tile rate $30/ft² → 60 × 0.7 × $30 = $1,260
  3. Fixtures: single vanity ($1,200) + toilet ($400) + shower ($3,000) = $4,600
  4. Material subtotal before region = 6,000 + 1,260 + 4,600 = $11,860
  5. Labor core: 60 × $55 × scope factor (1.0) × quality factor (1.0) × location factor (1.0) = $3,300
  6. Demolition add: 60 × 7 = $420 → labor total = $3,720
  7. Region factor 1.0 (no change)
  8. Permit = (material + labor) × 2% = (11,860 + 3,720) × 0.02 = $311.60
  9. Subtotal = 11,860 + 3,720 + 311.60 = $15,891.60
  10. Contingency = 10% × 15,891.60 = $1,589.16
  11. Total = 15,891.60 + 1,589.16 = $17,480.76
  12. Unit cost = 17,480.76 / 60 ft² = $291.35 per ft² (rounded)

We estimate the total cost at $17,480.76, with a unit cost of $291.35 per ft².
