Bathroom Remodeling Across Three Generations of St. Charles Homes

St. Charles is not one housing market. Roughly a quarter of homes here were built since 2000, about a fifth date from the post-war years, and a smaller share predate 1939, concentrated in the historic districts near the river. What a bathroom remodel involves depends almost entirely on which of those three your house belongs to.

Historic homes near Old Town, Midtown, and the Commons. Built before indoor plumbing, so the bathroom was carved out of a bedroom or closet later. Waste lines take improvised routes, the framing was never sized for a tub, and the walls are plaster and lath over brick. None of it is quick, and a quote that says otherwise has not looked.

Post-war homes. Compact hall baths built around a standard five-foot cast iron tub, often the only full bathroom in the house. The tub is usually sound, and the surround around it is not.

Homes built since 2000. Large primary baths with a garden or jetted tub that stopped being used years ago, alongside builder-grade finishes that were never specified to last this long.

We work out which one we are dealing with before we quote. In the older housing especially, that means opening things up and testing rather than pricing from a walkthrough and revising later.

Our Bathroom Remodeling Services in St. Charles

Tub to Shower Conversion

The conversion is straightforward. What varies in St. Charles is what sits underneath. In a home built since 2000, the answer is usually nothing, and it is a clean swap. Near Old Town, a cast iron tub has often spent a century on framing that was never sized to carry it, and that gets dealt with before any new base goes down. If the point of the project is staying in the house longer, we build it that way from the start with a curbless entry and a bench. Most jobs still finish inside a day.

Shower Remodel and Shower Replacement

The two terms get used interchangeably. We treat them as different jobs. A replacement puts a new system into the footprint you already have, which is what most dated fiberglass surrounds need. A remodel changes the footprint, the entry, or both. The waterproofing does not change either way: it all comes out, the substrate gets inspected, and the new system is sealed from the backer board out in tile, acrylic, or onyx. Finished work is in the gallery.

Full Bathroom Remodel

In a newer home, this is a finish and layout project. In a historic one, it is closer to an undoing. Bathrooms in pre-plumbing houses were improvised into whatever space happened to be spare, and a full remodel is usually the first real chance to put the fixtures, the wall systems, and the ventilation where they should have gone. That takes longer and costs more than a refresh. We say so at the quote rather than halfway through.

Bathtub Replacement

Two things make this harder here than it sounds. The old tub is frequently cast iron, and the way out is frequently a narrow stairwell with a turn in it. We work out the removal route before installation day and cut the tub in place where carrying it whole is not realistic. The replacement holds heat better and uses less water, and the wall and floor around it get rebuilt rather than patched over.

Bathroom Walls

Plaster and lath is why this matters more in St. Charles than in a newer market. A panel kit screwed over old plaster looks finished and traps moisture against a wall that was never built to shed it. We take wet-area walls back to sound framing and rebuild in tile, acrylic, onyx, or solid surface, sealed as a system rather than caulked at the joints. It is the least visible part of a full renovation and the part that decides how long everything else lasts.

What a Bathroom Remodel Costs in St. Charles, MO

Every bathroom is different, and the final number depends on size, layout, and materials. These are our typical ranges:

Service	Typical Range	Notes
Shower remodel or shower replacement	$4,500 to $12,000	Acrylic, onyx, or tile; most completed in one day
Tub to shower conversion	$4,500 to $12,000	Structural prep, new base, walls, and fixtures
Bathtub replacement	$4,500 to $12,000	Includes wall surround; most completed in 1 to 2 days
Bathroom wall replacement	$1,500 to $5,000	Tile, acrylic, or solid-surface systems
Full bathroom remodel	$14,000 to $35,000	All surfaces, fixtures, plumbing, and electrical; one to two weeks once work begins

Ranges are estimates and may vary. A straightforward finish replacement sits at the low end. Older homes near Old Town sit higher when there is structural repair behind the finishes, which is why we test before quoting rather than after demolition. Your guaranteed price is provided at your free in-home consultation with no obligation, and the price we quote is the price you pay. Full ranges are on our pricing page.

Permits and Inspections in St. Charles, Handled For You

Two different offices handle bathroom permits here, and which one applies depends on your address. Homes inside city limits go through the City of St. Charles Building Division. Homes in unincorporated St. Charles County go through the County’s Building and Code Enforcement Division. The requirements and timelines are not the same.

Any plumbing or electrical change needs a permit. The City also requires the general contractor, plumber, electrician, and HVAC contractor to each be licensed and bonded with the City, and it will not release a permit until every trade is listed and verified. That is where out-of-area contractors lose weeks. We do our own work with our own employees, so there is no roster of subcontractors to register before your job can start.

How We Work

Free In-Home Consultation

We come to your St. Charles home for measurements, photos, and a full walkthrough. In older homes, we check the subfloor, the waste line routing, and the wall construction before pricing anything, because plaster over brick behaves differently from drywall over studs. Samples come with us, or you can visit the showroom at 755 Friedens Rd.

Quote and Approval

After your consultation, we prepare a clear, straightforward quote with no hidden fees. You have a guaranteed price before we leave. Once you approve it, we move into scheduling and material orders.

Ordering and Scheduling

All materials are custom ordered to your bathroom's exact dimensions. We also pull and manage your permits, filing with the City or the County depending on your address, then assign a dedicated crew to stay on your job until it is finished.

Installation and Completion

Our installers focus only on your bathroom, no bouncing between jobs. Showers and shower replacements are usually done in a day. Full remodels take one to two weeks once work begins. If we find damage behind the walls, we stop and show you before rebuilding. We walk the finished space with you, and the price we quote is the price you pay.

Why St. Charles Homeowners Choose Us

We do not take shortcuts, and we do not hide problems behind new walls. That is the whole pitch. Here is what stands behind it.

A showroom you can walk into. We are based here, at 755 Friedens Rd. Most companies serving this market dispatch from somewhere else.
25 years and more, remodeling bathrooms and nothing else. We are specialists, not a general contractor who also does bathrooms.

No subcontractors. Every installer in your home is our own employee. In St. Charles, that also means faster permitting, because the City holds a permit until every trade on it is licensed and verified.
NKBA and NARI members, so the work answers to industry standards and not only to ours.
Direct manufacturer partnerships with The Onyx Collection, Fleurco, and others. Several brands rather than one pushed line, which means wider design choice and no middleman markup.

Our crews start your project and stay on it until it is done. Homeowners mention the cleanliness about as often as the work itself, which probably tells you something about both.

Frequently Asked Questions

Do I need a permit for a bathroom remodel in St. Charles?

For most remodels, yes. Any plumbing or electrical change requires one. The detail that trips people up is which office handles it. If your home is inside St. Charles city limits, permits go through the City’s Building Division. If you are in unincorporated St. Charles County, they go through the County’s Building and Code Enforcement Division. The two have different requirements and different timelines. We file with whichever applies to your address.

How long does a bathroom remodel take in St. Charles?

Shower remodels and shower replacements are usually finished in a single day. Full bathroom remodels take one to two weeks once work begins. Materials are custom ordered for your space, so allow about four to six weeks between your consultation and your start date. Older homes sometimes add time when we find damage behind the walls, and we will tell you as soon as we see it rather than at the end.

Why do some contractors struggle to pull permits in St. Charles?

The City requires the general contractor, plumber, electrician, and HVAC contractor to each be licensed and bonded with the City. A permit can be reviewed but will not be released until every trade is listed and verified. Contractors from outside the area often discover this after the sale, which is where the delays start. Because our own employees do the work rather than a chain of subcontractors, there is no roster of trades to register before your job can begin.

Can you remodel a bathroom in an Old Town or historic district home?

Yes, and it is some of the most careful work we do. St. Charles has several National Register districts, including Midtown, the Commons Neighborhood, and Lindenwood, with houses dating to the 1850s. A district listing does not generally restrict interior work. If your project changes a window or adds an exterior vent, check whether local preservation review applies before scheduling. We will flag anything that looks like it needs checking at the consultation.

What happens with plaster and lath walls?

They are common in older St. Charles homes, and they change how the job runs. Plaster is heavier and more brittle than drywall; it cracks along the lath once disturbed, and it hides its true condition until it is opened. In wet areas, we take it back to sound framing and rebuild with a properly waterproofed system rather than patching around it, because a patched plaster wall behind a shower is a leak waiting to happen.

Do you have a showroom I can visit?

Yes. We are based in St. Charles at 755 Friedens Rd, which is unusual in this trade around St. Louis, where most bathroom companies run out of a truck and a call center. You can see and handle acrylic, onyx, and tile in person before you decide anything. We also bring samples to your home at the free consultation if that is easier.

What is the difference between a shower remodel and a shower replacement?

In practice, they lead to the same outcome. A shower replacement usually means taking out an existing unit, most often a dated fiberglass or acrylic surround, and installing a new system in the same footprint. A shower remodel more often means changing the size, the layout, or the entry. Either way, we remove what is there, deal with whatever is wrong behind it, and rebuild waterproofed from the backer board out.

How much does a bathroom remodel cost in St. Charles?

Shower remodels and shower replacements run $4,500 to $12,000. Bathtub replacements run the same, and full bathroom remodels run $14,000 to $35,000. Older homes near Old Town sit higher when there is structural repair behind the finishes, which is exactly why we test before quoting rather than after demolition. You get a guaranteed written price at your free consultation, and the price we quote is the price you pay.

Which areas near St. Charles do you serve?

All of St. Charles plus St. Peters, Cottleville, Weldon Spring, O’Fallon, Chesterfield, Ballwin, and the wider St. Louis metro. Our location at 755 Friedens Rd serves the whole region, and being based here means shorter lead times on service calls than companies dispatching from across the river.
