Bathroom remodel costs in Missouri
Published national planning ranges span roughly $2,500–$30,000 for a full bathroom remodel, with a typical mid-range project near $12,000 — our bathroom remodel cost guide breaks the number down. Missouri usually prices below that midpoint. St. Louis and Kansas City quotes commonly land at or just under the national average, while Springfield, Columbia, St. Charles County, and the rural counties frequently come in lower on cheaper labor.
Shower projects follow the published national band of about $3,500–$15,000 described in our walk-in shower cost guide. Missouri's older housing adds its own variable: St. Louis's brick homes and Kansas City's prewar neighborhoods often hide cast-iron drains and layered past repairs behind bathroom walls, so experienced contractors quote a contingency — be cautious of any bid that assumes a century-old bathroom will open up clean.
Ranges here are 2026 planning figures drawn from published national data; actual quotes vary by home, scope, materials, contractor, and city.
Licensing is a city-by-city question in Missouri
Missouri does not license general contractors at the state level — the only construction trade with a statewide credential is electrical contracting, licensed through the Office of Statewide Electrical Contractors at the Division of Professional Registration. Everything else is local. St. Louis requires contractors working in the city to hold a business license through its License Collector; Kansas City runs a contractor licensing program backed by trade certificates of qualification; Springfield and other cities have their own rules. A license from one Missouri city does not transfer to another.
That patchwork puts verification on the homeowner's checklist: ask what license or registration your city requires, verify the electrician's statewide license if the project includes electrical work, and confirm permit requirements with your local building department — plumbing, electrical, and structural changes typically need one. Requirements change city by city and year by year, so confirm current rules with your municipality and the Division of Professional Registration.
- No statewide GC license — St. Louis, Kansas City, and Springfield each license locally
- Only electrical contractors hold a statewide Missouri license
- A city license does not transfer to other Missouri cities
- Permits are municipal; check with your local building department
Brick homes, basements, and four real seasons
Missouri's two housing personalities shape bathroom work. St. Louis is famous for its brick housing stock — solid masonry homes where bathrooms are compact, walls are unforgiving to move, and plumbing often dates back generations. Kansas City and its suburbs skew toward postwar ranches and split-levels, where basement bathroom additions and upgrades are among the most common projects in the state. The climate swings both directions: humid summers demand real ventilation, and hard winter freezes put supply lines in exterior walls at risk. Hard water is common across much of Missouri, so spot-resistant finishes and easy-clean glass are frequent quote line items.
What Missouri homeowners ask for
- Tub-to-shower conversions in St. Louis brick homes and KC ranches
- Basement bathroom additions in split-levels and raised ranches
- Hall-bath refreshes in postwar suburban housing
- Hard-water-friendly fixtures and finishes

Missouri bathroom remodeling questions
Does Missouri license bathroom remodelers?
Not at the state level — Missouri has no statewide general contractor license. Only electrical contractors carry a state credential, through the Office of Statewide Electrical Contractors. Remodeling contractors are licensed or registered by cities: St. Louis, Kansas City, and Springfield each run their own programs. Confirm current requirements with your city.
Are remodels cheaper in Missouri than the national average?
Often. St. Louis and Kansas City quotes commonly sit at or just under the national midpoint near $12,000 for a mid-range remodel, and smaller cities and rural counties frequently price lower. Older housing stock can add repair costs once walls open.
Do I need a permit for a Missouri bathroom remodel?
Permits are issued locally and typically required for plumbing, electrical, and structural changes; cosmetic updates often do not need one. Confirm with your city or county building department before work starts.
Is a Kansas City license valid in St. Louis?
Generally no — Missouri cities license contractors independently, and credentials do not transfer between jurisdictions. Ask each contractor which city licenses they actually hold for your location.
