How the estimate works

Bathroom remodels are priced as a whole project, not by the square foot — so this calculator starts from a national installed-cost range for your bathroom type (a powder room is a different animal from a primary suite) that already assumes a typical room size. It then scales that range by your finish quality, the scope of work, and your region, and adds a flat amount if you're converting a tub to a shower.

A half bath runs about $3,000–$8,000, a standard full bath about $8,000–$20,000, and a primary suite $18,000–$50,000. Quality tier multiplies that range from budget (×0.7) up to luxury (×2.2), scope runs from a cosmetic refresh (×0.5) to a full gut (×1.35), and region swings labor up or down. The midpoint is then split into the trades — labor, fixtures and plumbing, tile, vanity and counter, the shower or tub, and everything else — so you can see where the money goes.

What drives the price

  • Plumbing moves are the single biggest budget-buster — relocating the toilet, tub, or sink means opening walls and floors for new rough-in.
  • Finish quality is the next lever — tile, stone counters, and a glass shower enclosure can double a budget bath.
  • Scope matters most: a cosmetic refresh costs a fraction of a full gut to the studs with a new layout.
  • Region swings labor 40% or more between rural areas and coastal metros.

Common mistakes

  • Moving plumbing to chase a layout. Sliding the toilet three feet can add thousands — keep fixtures where they are when you can.
  • Cutting corners on waterproofing. Skimping on the membrane or backer behind tile invites a hidden leak that costs far more than it saved.
  • Skipping the exhaust fan. An undersized or missing fan leads to mold and peeling paint within a year.
  • Taking one bid. Remodel bids for the same scope routinely vary 30–40%. Always get three.

When this calculator is the wrong tool

Use a contractor walkthrough for: bathrooms with water damage, mold, or rotted subfloor; additions that add a brand-new bathroom (which needs new plumbing stacks); accessibility/aging-in-place conversions; and condos where association rules dictate fixtures and waterproofing. This tool estimates a standard remodel of an existing bathroom.

FAQ

Questions, answered

How much does the average bathroom remodel cost?
A standard full bathroom remodel runs roughly $8,000–$20,000 installed, with the national midpoint around $12,000–$14,000. A half bath (powder room) is far less — about $3,000–$8,000 — and a primary/master suite can run $18,000–$50,000+. Quality of finishes, whether you move plumbing, and local labor rates drive most of the spread.
How much does it cost to convert a tub to a walk-in shower?
A tub-to-shower conversion typically adds about $3,000–$10,000 on top of the base remodel, depending on whether it's a prefab shower pan and surround or a fully tiled custom shower with a glass enclosure. Tiled custom showers with curbless entries and waterproofing sit at the top of that range.
How can I save money on a bathroom remodel?
The biggest lever is keeping the toilet, tub, and sink in their existing locations — moving plumbing rough-ins is the #1 budget-buster. Reface or paint the vanity instead of replacing it, choose porcelain tile over natural stone, keep the existing layout, and do your own demo and painting. Don't cut corners on waterproofing behind tile or on the exhaust fan.
What does a small bathroom remodel cost?
A small or guest bathroom (around 35–40 sq ft) on a cosmetic-to-standard scope usually lands at about $4,000–$12,000. Going to the studs, re-tiling, and replacing the tub or shower pushes it higher. Small rooms still need the same fixtures and waterproofing as big ones, so the per-square-foot cost is often higher than you'd expect.
Does a bathroom remodel add value to my home?
A midrange bathroom remodel recoups roughly 60–70% of its cost at resale, per industry Cost-vs-Value data — better than most kitchen or addition projects but rarely 100%. A clean, modern, leak-free bathroom helps a home sell faster. Over-customized luxury baths recoup the least, so remodel for how you'll live, not purely for resale.
