Not sure how far you want to take your bathroom project?
Bathroom projects range from a tub-to-shower conversion or a shower replacement, which are the most common, through to a full bathroom remodel that moves fixtures and finishes. Walk-in tubs are a separate product aimed at accessibility rather than a general remodel.
Scope drives price here more than anything else. Replacing a tub or shower in its existing footprint is a very different job from relocating plumbing, and it is worth being clear which one you are asking contractors to quote.

Water hardness varies by local source across this region. Check with your utility before assuming you need a softener. Focus remodel dollars on layout and storage, which drive more of the resale value here.
Bathroom Remodeling in St. Louis usually runs $9,000–$27,000 for a standard project on an average home. That is higher than the average national rate, because labor costs are higher in St. Louis. The table below compares national averages with typical St. Louis pricing.

Installed cost in St. Louis runs roughly 4% above the national average for this trade. Here's how we got to that number.
Project costs include three main components: labor, materials, and overhead. Material ships at national prices no matter where you live, and overhead is fairly consistent as well. So the main pricing difference between metro areas is labor costs. This is why a quote from a high-wage metro is rarely as far above the national average as people expect.
To get St. Louis labor costs, we compared the average hourly wage in the St. Louis, MO-IL area to the national average hourly wage for this trade. (source: US Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2025)
We found that the local trade wages sit about 12% above the national figure. Labor costs typically make up about 33% of a bathroom remodeling project cost, so the weighted difference between St. Louis and national averages is +4%. See methodology and sources.
It depends on the scope of your project, so you should talk to the permitting authority to find out what your project needs. In general, St. Louis permitting is moderately complex compared to other metros we cover.
City of St. Louis and St. Louis County have separate permit offices. Older housing stock in the city proper often triggers additional review for lead paint and structural concerns.
You should ask each contractor if they pull the permits for you and if the fee for pulling permits is included in their quote. Also, tell them you need to see the written, approved permit before work starts.
There is no Missouri state license for bathroom remodeling. This work is governed locally. (source, verified as of 2026-08-12) What that means and how to verify a contractor in Missouri →

Bath Fitter pioneered the one-day acrylic model in 1984, fitting a new tub or shower wall directly over your existing one rather than tearing it out. Reviewers across the network consistently credit their individual installer by name for careful, clean work, and many describe installers thoughtfully accommodating specific needs, whether seat height, grab-bar placement or a lower threshold, for aging-in-place remodels. The acrylic itself carries a lifetime warranty against manufacturing defects with no date limit; the June 2023 date some homeowners see governs only whether that warranty transfers to a new owner, and doors, faucets, and other plumbing fixtures fall under their own separate terms. Because the new surface is sealed directly over the old one rather than replacing it, ask your installer to walk you through how the seams at the drain and walls are finished and inspected, a detail worth understanding for a job built this way.
Jacuzzi is among the best-known names in bathing, but the local businesses that carry its name are full bathroom remodelers first. Most of what they install, and most of what their customers write about, is shower installations and tub-to-shower conversions rather than the walk-in tub itself. Those businesses are independently owned dealers, not branches of one company, working under a program that BathWraps administers; Jacuzzi owns BathWraps and makes the wet-space products there, but does not run the storefront. What that means in practice is that the tub and its product warranty come from Jacuzzi, while the sale, the installation and the service afterwards come from that local dealer, several of whom are well-established remodelers in their own right. The dealer’s own labor warranty is the thing to ask about, since Jacuzzi’s covers the product rather than the fitting.
American Standard is a long-established plumbing name, and its walk-in tubs are sold and installed under Safety Tubs Company, an American Standard affiliate, rather than through a national storefront of its own. The tub itself draws steady, specific praise: reviewers point to the door-seal design and the FAST Drain system, which empties the tub in about five minutes instead of the usual eight to twelve, and installers who take real care with unusual situations. One homeowner’s crew added custom support blocking so the tub’s height would work with a home Hoyer lift. Because the affiliate carries out both the installation and, later, any warranty repairs, it is worth settling two things before you commit: who will actually be doing the work in your area, and how quickly that same local affiliate can schedule a service visit if something needs attention down the road.
Kohler Walk-In Bath brings the KOHLER name to accessible bathing, with hydrotherapy, air massage and chromotherapy built in. The safety and comfort features are the product’s main selling point day to day. Two things are worth checking before you order. Confirm your water heater can keep up with the fill time on a jetted tub, and measure your doorway and floor space against the exact tub dimensions.
The Bath Authority takes the wet space out to the studs and subfloor and replaces the rough plumbing before fitting its own solid-surface panels: a fuller job than a liner over the existing tub, and the clearest thing separating it from the overlay specialists. It works across Ohio, Pennsylvania, Maryland and North Carolina, and is a Great Day Improvements brand. Reviewers name their installers more than any other detail (it is the most common thing homeowners mention) and describe floors protected from the bathroom right through the living room, with most jobs done in a day or two. Several also credit a named office contact for keeping them updated throughout. They advertise a lifetime warranty without publishing the terms, so ask for them in writing, along with a single point of contact for after the install. If your project includes a walk-in tub, ask about your water heater’s capacity, since a deeper tub takes longer to fill.
Mad City Windows & Baths started in Madison and now runs offices across sixteen states, covering windows, bath, and kitchen cabinet refacing. The same theme holds from Wisconsin to Iowa to Minnesota: reviewers name their installer specifically, and the praise is concrete: on time, explains the work as it happens, and leaves the house cleaner than the crew found it. Bath conversions are usually finished within a day or two. Mad City is a regional brand within the Renuity home improvement platform. If you are converting a tub to a shower, ask about the floor finish and how the drain is sealed. A few homeowners wanted more grip and better drainage than the standard base gave them.
Independent Home Products is unusual in this category: one company handles the product, the sale and the installation, with no separate dealer in between. Reviewers name their own sales consultant and installer by name, and describe a no-pressure consultation and a careful, respectful install. It covers walk-in tubs and roll-in showers, and backs its tubs with its own warranty rather than a manufacturer’s. Installs are typically a single day. Two practical notes. A walk-in tub takes several minutes to fill, so it is worth checking your water heater can keep up. And because the warranty is handled in-house rather than through a national program, it is worth asking directly how a service call gets scheduled if you ever need one.
