Bathroom Remodel Cost in St. Louis 2026: Budget Guide
Pat Melson, Owner & CEO, Midtown Home Improvements ·
Bathroom remodeling is one of the most requested home improvements in the St. Louis area — and one of the most misunderstood when it comes to pricing. A homeowner who budgets $10,000 based on a national average often gets surprised when local bids come in at two or three times that figure. A homeowner who hears "luxury bath remodel" and assumes $100,000 may not realize a beautiful, functional bathroom upgrade can happen for a fraction of that.
This guide gives you the real numbers for the St. Louis metro in 2026, broken down by project type — so you can budget accurately, understand what drives cost, and go into contractor conversations prepared.
Key Takeaways
- St. Louis bathroom remodels range from $18,000 (half bath refresh) to $85,000+ (primary suite with custom finishes) in 2026, with St. Louis labor running above many national estimates.
- A tub-to-shower conversion runs $5,000–$15,000+ depending on whether you choose a surround system or custom tile — the single biggest swing factor in bathroom remodel pricing.
- Mid-range bathroom remodels recover approximately 70–80% of cost at resale nationally, making them one of the better-returning home improvement investments.
- A detailed, itemized written estimate — specifying materials, labor, permits, and scope — is the single most effective way to protect your budget.
What Does a Bathroom Remodel Cost in St. Louis in 2026?
In 2026, St. Louis bathroom remodels typically run between $18,000 and $85,000+, depending on scope — with most homeowners landing somewhere between $25,000 and $55,000 for a full bathroom update, according to aggregated local contractor data from Aptitude Design & Build and Project Cost Atlas. Those figures are notably higher than many national averages you'll read online — and that gap is intentional.
St. Louis metro labor costs run above national benchmarks for skilled trades — a reflection of the region's construction demand and cost of living. Labor accounts for 40–65% of a total bathroom project budget. That means a national "average" of $12,000–$18,000 simply doesn't translate to what contractors in this market will actually bid.
Here's how costs break down by project type:
Half Bath / Powder Room: $18,000–$29,000
A powder room refresh — new vanity, toilet, tile, lighting, and paint with no plumbing relocation — typically runs $18,000 to $29,000 in the St. Louis market. These projects move faster (often 2–3 weeks) because the plumbing stays put and the space is small. The ceiling on this budget tier is a high-end vanity, designer tile, and a vessel sink — not structural changes.
Guest Bath / Hall Bath: $30,000–$48,000
A full 5×7 or 5×8 bathroom — tub or shower replacement, new vanity, updated tile, fresh fixtures, and proper ventilation — falls in the $30,000 to $48,000 range in St. Louis. If the layout stays the same (plumbing in existing locations), you land toward the lower end. Add a tub-to-shower conversion or move the vanity and you'll drift toward the upper range.
Primary Bathroom / Master Suite: $55,000–$85,000+
Primary suite renovations in St. Louis start around $55,000 when custom tile, a double vanity, a walk-in shower, and a freestanding tub are involved — and regularly exceed $85,000 for luxury finishes, heated floors, frameless glass enclosures, and high-end plumbing fixtures. These projects almost always involve some plumbing relocation and take 6–10 weeks to complete.
What Drives the Cost of a Bathroom Remodel?
Tub-to-Shower Conversion vs. Full Gut Remodel
The biggest single swing factor in bathroom remodel pricing is whether you're replacing like-for-like or reconfiguring the space. A tub-to-shower conversion — removing a standard tub and installing a shower in the same footprint — costs significantly less than a full gut and layout change.
In St. Louis, a tub-to-shower conversion runs $5,000 to $15,000+ depending on the materials chosen, per This Old House's 2026 tub-to-shower cost data. The lower end assumes a prefabricated surround system with minimal plumbing work. The upper end involves a custom tile walk-in shower with a curbless entry, frameless glass doors, and at least some drain relocation.
A full gut remodel — demo to studs, new waterproofing, new plumbing rough-in, new everything — adds $10,000 to $20,000 or more to any of the base figures above, because you're essentially building a room from scratch rather than refreshing it.
Surround System vs. Custom Tile
This is where homeowners most often get tripped up comparing bids. Two contractors can quote vastly different prices for what sounds like "a new shower" — because one is pricing a prefabricated surround system and one is pricing custom tile work.
Acrylic or solid-surface surround systems install in 1–2 days, have no grout lines to maintain, and run $5,000–$10,000 installed for a standard tub-to-shower footprint, per This Old House's 2026 tub-to-shower cost data. They're non-porous, mold-resistant, and backed by strong manufacturer warranties when installed by a certified contractor. These are an excellent choice for homeowners who want a low-maintenance, fast-turnaround upgrade.
Custom tile showers cost $8,000–$15,000 for the wall system alone — and that's before you account for a glass enclosure, updated fixtures, or waterproofing membranes. The tile itself can represent only a fraction of the cost; the labor to set, grout, and seal it is where the budget goes. Installation takes 1–3 weeks depending on the pattern complexity. The long-term durability of a properly installed tile shower is excellent, but grout maintenance is ongoing.
Vanity Grade
A basic builder-grade vanity runs $200–$600 at retail; mid-range semi-custom vanities run $800–$2,500; fully custom cabinetry can reach $5,000–$12,000 or more. Labor to install a vanity is roughly $300–$600 in the St. Louis market. Most homeowners in the $30,000–$48,000 budget tier land on a quality semi-custom vanity and save the budget for tile and fixtures.
Plumbing Moves That Require Permits
Here's the cost factor that catches the most St. Louis homeowners off guard: moving plumbing means a permit, and permits mean inspections, and inspections mean the work has to be done right. It also means timeline.
In St. Louis County and the City of St. Louis, any change to the plumbing supply lines, drain locations, or vent stack connections requires a plumbing permit. The permit fees typically run $150–$700+ depending on scope, according to St. Louis County's residential permit information. The bigger cost impact is labor: relocating a drain line adds $900–$1,100 to a project, and moving supply lines adds another $700 or more, per This Old House's 2026 tub-to-shower cost data.
Tearing out a tub without moving the drain? Usually no permit needed. Converting to a curbless shower that requires repositioning the drain toward the center of the floor? Permit required, plumber involved, budget impact follows.
Projects that typically require permits in St. Louis:
- Moving or adding drain lines
- Relocating supply lines or shutoffs
- Installing a new exhaust fan on a new circuit
- Adding or relocating a GFCI outlet
Projects that typically don't require permits:
- Replacing a vanity in the same location
- Swapping a toilet without moving the flange
- Painting or retiling in-place
- Installing a new vanity light on an existing circuit
Labor Rates in the St. Louis Market
St. Louis metro labor runs above the national average for skilled trades, which means labor-heavy projects — custom tile, plumbing relocation, waterproofing — hit harder here than many national estimates suggest. For a full bathroom remodel, labor alone can run $4,300–$6,900 for a standard project, rising significantly when specialized plumbing or electrical work is involved, according to Angi's St. Louis contractor data.
What's Included in a Full vs. Partial Bathroom Remodel?
Knowing what you're actually buying when a contractor quotes a "full remodel" versus a "partial update" is key to comparing bids fairly.
A full bathroom remodel typically includes:
- Demolition and disposal of existing fixtures, tile, and drywall
- Waterproofing membrane installation behind walls and under floor tile
- New plumbing fixtures (shower valve, tub spout or shower head, faucet, toilet)
- New shower or tub surround (tile or acrylic system)
- New floor tile or LVP
- New vanity, sink, and faucet
- Updated lighting and exhaust fan
- New mirror or medicine cabinet
- Fresh paint and trim
A partial update might include just:
- Replacing the vanity and faucet
- Replacing the toilet
- Painting
- Adding new lighting
The distinction matters because two contractors quoting different scopes will produce wildly different numbers. Always make sure the scope of work is written out before you compare bids.
ROI on a Bathroom Remodel in St. Louis
Is a bathroom remodel worth the investment when you sell? The data suggests yes — within limits.
According to the 2025 Remodeling Magazine Cost vs. Value Report, a mid-range bathroom remodel nationally recovers approximately 70–80% of its cost at resale. On a $40,000 project, that's $28,000–$32,000 added to sale price — a significant but not dollar-for-dollar return. Upscale remodels (think $70,000+ primary suites) recover only around 45% on average, making them better lifestyle investments than pure financial ones.
What improves ROI on a bathroom remodel:
- Mid-range material selections (not builder-grade, not ultra-luxury)
- A clean, neutral aesthetic that broad buyers will find appealing
- Functional upgrades — an improved shower, better lighting, storage
- Addressing actual problems: mold, poor ventilation, aging fixtures that suggest deferred maintenance
What hurts ROI:
- Highly personalized design choices (unusual tile colors, niche fixtures)
- Over-improving relative to the neighborhood's price point
- Full gut remodels on homes where the kitchen is still original
How to Get Accurate Contractor Bids in St. Louis
Getting an accurate estimate isn't just about the bottom number. It's about giving the contractor a complete, defined scope so the estimate reflects your actual project.
Step 1: Define your scope in writing before you call anyone. Note the current bathroom dimensions, what you want to keep versus replace, whether any plumbing moves are involved, and your material tier preferences (builder-grade, mid-range, or high-end). The more specific you are, the more accurate the bids will be.
Step 2: Request a detailed, itemized written estimate. A professional estimate should be an itemized line-item breakdown — labor by trade, materials by brand and grade, permit costs, and disposal separately. A vague one-page total price doesn't give you enough information to evaluate what you're actually buying.
Step 3: Read the estimate line by line, not just the total. If the estimate is vague — 'bathroom remodel' with a single number — ask for a full itemized breakdown before proceeding.
Step 4: Verify license, insurance, and references. In Missouri, general contractors and specialty trades (plumbing, electrical) must be licensed. Ask for a copy of the contractor's license number and verify it with the Missouri Division of Professional Registration. Uninsured contractors lower their bid by shifting risk to you — if a worker is injured on your property, you could be liable.
Step 5: Budget a 10–20% contingency. Nearly 70% of tub-to-shower conversion homeowners encountered at least one hidden cost during their project, according to This Old House's 2026 survey data. In St. Louis's older housing stock — many homes predate 1960 — opening walls often reveals galvanized plumbing, inadequate waterproofing, or subfloor issues that weren't visible before demo. A 10–20% contingency isn't pessimism; it's planning.
What to Expect from the Remodel Timeline and Process
A realistic St. Louis bathroom remodel timeline looks like this:
Week 1–2: Planning and permit application. Your contractor finalizes the scope, orders materials (especially tile and custom vanities, which can have 2–4 week lead times), and applies for any required permits. Don't let anyone start demo before permits are in hand.
Week 2–4: Demolition and rough-in. Existing fixtures, tile, and sometimes drywall come out. If plumbing or electrical moves are planned, this is when they happen — and when inspections occur. Expect the bathroom to be completely out of commission during this phase.
Week 3–6: Installation. Waterproofing, tile or surround system, flooring, vanity, fixtures, lighting, and trim. For a surround system install, the wall work alone takes 1–2 days. Tile work takes 1–3 weeks depending on complexity.
Week 5–8: Final trades and punch list. Plumbing and electrical finals, touch-up paint, hardware installation, glass enclosure (if applicable), and a final walkthrough with your contractor.
For reference, a tub-to-shower conversion with a prefabricated surround system — the fastest turnaround option — can complete the actual installation in as little as one day when the scope is limited to the shower area itself. Full-room remodels consistently take 4 to 8 weeks, according to Aptitude Design & Build's St. Louis timeline data.

St. Louis labor rates run above many national estimates, which is why local quotes often surprise homeowners who've only seen national averages.
How much does a tub-to-shower conversion cost in St. Louis?
A tub-to-shower conversion in St. Louis ranges from $5,000 to $15,000+, depending on materials. A prefabricated acrylic or solid-surface surround system runs $5,000–$10,000 installed. A fully custom tile walk-in shower runs $8,000–$15,000 for the wall system alone. Moving the drain line adds $900–$1,100; relocating supply lines adds another $700 or more.
Do I need a permit for a bathroom remodel in St. Louis County?
Yes, for most structural changes. St. Louis County and the City both require permits when a remodel involves plumbing, electrical, or structural changes. Permit fees range from $150 to $700+ depending on scope. Cosmetic work — paint, vanity swap, mirror replacement — generally doesn't require a permit. Always confirm with your contractor before assuming a permit isn't needed.
What is the ROI on a bathroom remodel in St. Louis?
A mid-range bathroom remodel recovers approximately 70–80% of its cost at resale nationally, per the 2025 Remodeling Magazine Cost vs. Value Report. Upscale remodels recover around 45%. In the St. Louis market, updated bathrooms consistently rank as a top purchase driver in buyer feedback — so the non-financial ROI (faster sale, stronger offers) is real even when the dollar math isn't 100%.
Should I choose a surround system or custom tile for my shower?
Both are good options depending on your priorities. Acrylic and solid-surface surround systems install in 1–2 days, require no grout maintenance, and run $5,000–$10,000 installed. Custom tile showers cost $8,000–$15,000 and take 1–3 weeks to install, but offer more design flexibility and longer potential lifespan. For homeowners who want a fast turnaround, low ongoing maintenance, and a clean modern look, a quality surround system is hard to beat.

A full bathroom remodel typically takes 4 to 8 weeks in St. Louis, from demolition to final walkthrough. Simple cosmetic updates can wrap in 1–2 weeks. A tub-to-shower conversion with a surround system can complete the installation itself in 1–2 days. Full gut remodels with permit-required plumbing work run 6–12 weeks when permit lead times are factored in.
