Room Renovation Cost Estimator

Get a ballpark cost range for remodeling a kitchen, bathroom, bedroom, living room, or basement based on room size and the quality level you're targeting.

This estimator gives you a ballpark remodel cost range for a single room. Choose the room type, enter its size in square feet, and pick a quality tier. The result is a planning range in dollars โ€” useful for budgeting and for sanity-checking contractor bids. It is not a quote; real prices vary widely by location, contractor, and finishes.

sq ft

A typical U.S. kitchen is ~150โ€“250 sq ft; a full bath ~40โ€“100 sq ft.

How the estimator works

CalcReno multiplies your room size by a cost-per-square-foot range for that room type and quality tier, drawn from broad national remodeling cost ranges. Kitchens and bathrooms carry higher per-square-foot ranges because they involve plumbing, electrical, cabinetry, and tile; bedrooms, living rooms, and basement finishing are typically lower. The output is a low-to-high range, because finishes and site conditions move the final price substantially.

How to use the number

  • Budget with the high end. Surprises in renovation almost always cost money, not save it.
  • Get 2โ€“3 written quotes from licensed local contractors before you commit.
  • Hold a contingency of 10โ€“20% for the unexpected โ€” old wiring, water damage, or code upgrades.
  • Separate "wants" from "needs." Layout changes that move plumbing or walls are where budgets blow up.

Two worked examples

Example 1 โ€” a mid-range bathroom. A 60 sq ft full bathroom at a mid-range per-square-foot range lands in a broad planning band โ€” say the low and high ends of that tier multiplied by 60. Bathrooms read expensive per square foot because waterproofing, tile, and several plumbing fixtures are packed into a tight space. Keeping the toilet, tub, and vanity in their existing spots is the single biggest way to stay near the low end.

Example 2 โ€” a budget bedroom refresh. A 150 sq ft bedroom at the budget tier sits much lower per square foot, because the work is mostly drywall, paint, flooring, trim, and lighting with no plumbing. Add cost only if you build out a closet, replace windows, or upgrade to premium flooring. This is why the same square footage can cost three times more as a kitchen than as a bedroom.

What moves your number inside the range

The estimate is a band, not a point, because finishes and scope swing the total. The biggest lever is whether you change the layout: moving plumbing, gas, or walls adds trades, permits, and time. After that, finish level dominates โ€” stock versus custom cabinets, laminate versus stone counters, builder-grade versus designer fixtures. Older homes also tend to reveal hidden work once walls open, from outdated wiring to water damage, which is why a contingency is essential rather than optional.

Where renovation money goes

Per square foot, kitchens and bathrooms cost the most because of plumbing, electrical, and cabinetry. Here's the rough split:

CategoryWhy it matters
CabinetryUsually the largest single share in a kitchen
CountertopsLaminate โ†’ quartz โ†’ natural stone
Appliances & fixturesEasy to scale up or down by tier
Labor & installationRises sharply if the layout changes
Flooring, lighting, paintSmaller pieces that add up

Costs vary widely by location and finishes โ€” this is a planning range, not a quote.

Common mistakes to avoid

  • Moving plumbing or walls when the budget is tight.
  • Forgetting a 10โ€“20% contingency for hidden surprises.
  • Budgeting with the low end of a range instead of the high end.
  • Splurging everywhere instead of picking one or two priorities.
  • Skipping written, itemized quotes from licensed contractors.

Frequently asked questions

How accurate is a renovation cost estimator?

An online estimator gives you a planning ballpark, not a quote. Real costs depend heavily on your location, the contractor, material choices, structural surprises, permits, and labor rates. Use this range to budget and to sanity-check bids โ€” then get at least two or three written quotes from licensed local contractors before committing.

Why is the cost shown as a wide range?

Because finishes drive the price as much as size. The same 100 sq ft bathroom can be a modest refresh or a fully reconfigured spa with moved plumbing. The budget, mid-range, and high-end tiers reflect that span. Your final number lands inside the range based on the choices you make.

Which rooms cost the most to renovate?

Per square foot, kitchens and bathrooms are usually the most expensive because of plumbing, electrical, cabinetry, tile, and appliances. Bedrooms, living rooms, and basic basement finishing typically cost less per square foot since they involve fewer trades.

What's not included in this estimate?

Treat the figure as construction and finishes only. It does not account for permits, design fees, structural changes, hazardous-material removal (like asbestos or knob-and-tube wiring), or major layout reconfiguration. Those can add meaningfully to a project and vary widely by home and region.
