Labor shares differ a lot between sources: HomeAdvisor puts labor at 40 to 65 percent of a bathroom remodel and Fixr at about 50 percent (HomeAdvisor (Angi Inc.), Bathroom Remodel Cost (Updated 2026-06-17); Fixr, Bathroom Remodel Cost (Updated 2026-01-27)). Ask each contractor to split labor and materials in the quote.

What Moves the Price

  • Moving plumbing. Relocating a toilet, shower or sink means changing drain, vent and water pipes. That needs a plumbing permit almost everywhere and a rough-in inspection before the walls close (City of Benson, Arizona, Work not requiring a Permit, according to the 2024 IRC (undated handout quoting the 2024 IRC); Springville City, Utah, Community Development, Work Exempt From Permits, 2021 IRC (2025-07-21 (file revision date))).
  • Tile. Material, size and pattern change both the price and the setting time.
  • Shower type. This Old House prices a basic prefabricated walk-in shower at $4,000 to $7,000 and a midrange tiled one at $8,000 to $13,000 (This Old House, Walk-In Shower Cost (Updated 2026-10-07 (shown as 10/07/2026))).
  • Ventilation and electrical. The model code needs a fan of at least 50 cfm (on demand) vented outdoors unless the room has an openable window, and new wiring needs a permit (City of Boise, Planning and Development Services, IRC Code Handout Section R303: Light & Ventilation (#433) (2022-01)).
  • Region. Labor rates vary by metro. Our city pages show local reference costs.

Frequently Asked Questions

What is the cheapest way to remodel a small bathroom?

Keep the layout, reuse the tub if it is sound, choose a stock vanity and standard tile, and spend the savings on waterproofing and ventilation.

How long does a small bathroom remodel take?

Most small bathroom remodels take 1 to 3 weeks once materials are on site (This Old House, Small Bathroom Remodel Cost (2026-06-08)).

Do I need a permit to remodel a bathroom?

Usually when plumbing, wiring, ventilation or walls change. The model code exempts finish work such as paint, tile and new cabinets, but some cities require a permit for any bathroom remodel, so check with your building department (City of Benson, Arizona, Work not requiring a Permit, according to the 2024 IRC (undated handout quoting the 2024 IRC); City of Pleasanton, California, Building and Safety Division, Residential Bathroom Alteration Requirements (2026-01 (revision JLA 01.26))).

Is a tub-to-shower conversion worth it?

It suits households that never use the tub. See our tub to shower conversion cost guide.

How much contingency should I add?

This Old House recommends setting aside 20% of a bathroom budget for surprises, and Fixr suggests about 5% (This Old House, Bathroom Remodel Cost (2026) (2026-07-02); Fixr, Bathroom Remodel Cost (Updated 2026-01-27)). Older homes need the larger reserve.

Does a bathroom remodel add home value?

Partly. The 2025 NAR Remodeling Impact Report puts the cost recovered for a bathroom renovation at 50%, and HomeAdvisor cites 70% (National Association of REALTORS (with NARI cost survey), 2025 Remodeling Impact Report (April 2025 (released 2025-04-09)); HomeAdvisor (Angi Inc.), Bathroom Remodel Cost (Updated 2026-06-17)).
