Bathroom Remodel Cost in Illinois (2026)
Our estimate for a bathroom remodel in Illinois is $15,750, in a range of $7,350 to $36,750. Our Illinois index sits 5% above our national baseline.
This is a modeled estimate, not a quote
We calculate the $15,750 figure above like this: $15,750 = $15,000 national baseline for a bathroom remodel × Illinois's 1.05 cost index. The low and high ends are the same baseline range ($7,000–$35,000) run through the same index. Both the baseline and the index are figures we set and publish ourselves — no contractor has priced your job, and nothing here is a bid.
In practice, written bids routinely land 30–50% either side of a modeled number, because a model cannot see your site conditions, your scope, or how booked your local trades are. Use this to set a budget and sanity-check a bid, then get at least three itemized quotes. Cost model last reviewed: August 2026. Full methodology.
Typical Illinois home value: about $260,000 — a rounded reference figure we maintain to put project cost in context, not an appraisal or a current market index | Region: midwest
If you are planning a bathroom remodel in Illinois, expect to pay somewhere in the $7,350–$36,750 range, with most projects settling near $15,750. That is roughly 5% above our national baseline, and the gap comes down to local realities rather than national trends.
The shower is the swing item in a bathroom. A drop-in tub with a surround is a fraction of the cost of a custom tiled shower with a proper waterproofing assembly and a linear drain. This is a goods-heavy job with labor at roughly 35%, and Illinois's material pricing is close enough to the national average that national figures are a fair starting point. One more layer sits on top of all this: Illinois as a whole is within a few points of the national baseline, so a published national figure is a fair opening reference for this market.
A bathroom is indoor work, but it is the room where humidity control matters most — ventilation sizing and moisture-tolerant materials are the details that decide how the work ages. In Illinois that runs up against cold winters with heavy freeze-thaw cycling, hot humid summers, and lake-effect weather along the Chicago shoreline. Illinois homes are overwhelmingly basement homes, so water management is a recurring cost, and Chicago's electrical rules add real labor to any project that touches wiring. Downstate labor rates run well below Chicago metro rates, and the gap is large enough to be worth a conversation if your property is near the boundary.
Costs are not uniform across the state either — homeowners in Chicago, Aurora, Rockford often see different quotes than those in smaller towns, which is why the city-by-city table below is usually more useful than a single statewide figure. The estimates here apply Illinois's labor index (1.1x) and material index (0.98x) to our national baseline. Those indices describe how far we judge Illinois to sit from the national average on trade wages and material and delivery costs — they are not a survey of local bids, and no contractor has quoted the number on this page.

How We Calculated the Illinois Estimate
Every figure on this page comes out of two hand-maintained files and one multiplication. There is no live pricing feed and no licensed cost database behind it, so rather than ask you to take the numbers on trust, here is the whole calculation for a bathroom remodel in Illinois:
| Figure | National baseline | Illinois index | Shown on this page |
|---|---|---|---|
| Low end | $7,000 | × 1.05 | $7,350 |
| Typical (mid-scope) | $15,000 | × 1.05 | $15,750 |
| High end | $35,000 | × 1.05 | $36,750 |
Where the baseline comes from. The $7,000–$35,000 national range for a bathroom remodel is an informed editorial estimate that we set and revise by hand. It is meant to be a range a working contractor would recognize, not a figure precise to the dollar.
Where the Illinois index comes from. We rate Illinois at a 1.05 overall cost index, built from a 1.1x labor index and a 0.98x material index. Those judgements are informed by publicly observable trade wage levels, retail material and delivery prices, and the state's permitting, licensing and code requirements — not by proprietary bid data, which we do not have.
The cost breakdown and city figures. The component amounts further apply the labor index to labor lines and the material index to material lines, so they show where money tends to go rather than summing exactly to the total. City figures apply an additional metro factor to the statewide number. Both are directional.
What this estimate is not. It is not a quote, a bid, an appraisal, or a guaranteed price, and it is not a claim about what any specific Illinois contractor charges. Real written bids routinely land 30–50% either side of a modeled figure — a model cannot see knob-and-tube wiring, a driveway a truck cannot reach, or the fact that the only licensed installer nearby is booked six months out. Treat this page as the start of the conversation and get at least three itemized quotes.
Last reviewed. The baselines and state indices behind this page were last reviewed in August 2026. We bump that date only when a person actually re-checks the underlying numbers, so it never claims a freshness the data does not have. The complete state-by-state multiplier table and our known limitations are published in the full methodology.
How this figure was calculated
The costs on this page are modeled estimates, not quoted prices. Each one starts from a national baseline range that we set ourselves for the project, which is then adjusted by our own state cost multiplier — and, for major metros, a further city factor. That is the entire calculation: a baseline we wrote down, multiplied by an index we built.
There is no live pricing feed behind this page and no licensed cost database. The figures are informed by publicly observable trade wage levels, regional material and delivery costs, and each state's published permit and code requirements — but the blending is an editorial judgment, and no government agency publishes or endorses our index.
What goes into the number
- National baseline ranges set editorially by HomeCostLab, one per project
- HomeCostLab state cost multiplier index — the full 50-state table is published on our methodology page
- Publicly observable construction-trade wage levels, regional material and delivery costs, and published state permit and code requirements
Treat this as an estimate, not a guaranteed figure.Real bids routinely land 30–50% away from a modeled estimate in either direction, because a model cannot see your site conditions, your scope, or your local contractor availability.

What $7,350, $15,750, and $36,750 Get You in Illinois
The same bathroom remodel can span a wide range depending on materials and scope. Here is what each price point typically buys at Illinois rates:
Budget
$7,350
Toward the bottom of the range, that means a surface-level update in the existing footprint — new vanity, toilet, mirror, light fixture, and paint, with the tub and tile left alone.
Standard
$15,750
At this level you are into a full replacement inside the existing walls: new tub or shower pan, tiled surround, tile floor, vanity with a solid-surface top, new fixtures and an exhaust fan that actually moves air.
Premium
$36,750
At the top of the range you are paying for a curbless or custom tiled shower, relocated fixtures, heated floors, a double vanity, and waterproofing detailed properly behind the tile rather than assumed.
How Homeowners Insurance Is Priced
Our guide explains what drives a premium, which coverage limits actually matter after a renovation, and how to compare policies without getting lost in the fine print.
Permits & Timing for a Bathroom Remodel in Illinois
Moving or adding plumbing fixtures and adding circuits are the triggers for a bathroom permit; swapping a vanity in place usually is not. As a rule: required for plumbing and electrical modifications — and in Illinois the inspection calendar, rather than the construction itself, is usually what sets your finish date. Tile and fixture availability, plus the number of separate trades that have to sequence through one small room, set a bathroom's timeline more than crew scheduling does. Illinois crews fill winter with interior work, so January and February starts are usually easier to get and better priced, so you have more scheduling latitude here than an exterior project would give you. Typical duration is 2–6 weeks depending on scope. Before the permit goes in: inside Chicago, confirm the electrician is city-licensed and the bid assumes conduit; outside it, check the municipality's own contractor requirements.
Paying for a Bathroom Remodel in Illinois
At $15,750, a bathroom remodel works out to about 6.1% of Illinois's $260,000 median home value — large enough to plan properly, small enough not to require restructuring your mortgage. A bathroom is usually small enough to sit inside personal-loan or credit-union territory rather than requiring a secured product, which keeps the paperwork short if your credit is solid.
How to Pay for a Bathroom Remodel in Illinois
With Illinois projects running $7,350–$36,750, most homeowners spread the cost rather than pay cash. These guides break down the financing options that fit a bathroom remodel of this size:

How to Save on a Bathroom Remodel in Illinois
- ✓Book against the local trade calendar rather than your own. Tile and fixture availability, plus the number of separate trades that have to sequence through one small room, set a bathroom's timeline more than crew scheduling does. Illinois crews fill winter with interior work, so January and February starts are usually easier to get and better priced, so a booking made then usually gets you a better crew at a better price than a spring enquiry would.
- ✓Do not stop at three quotes — make them comparable. Ask exactly how the shower will be waterproofed and by whom. A bathroom bid that does not name the waterproofing method — a sheet or liquid membrane system, not just cement board — is hiding the one detail that determines whether you are re-doing this room in five years. With Illinois tracking national pricing, any large gap between two bids is telling you they scoped the job differently.
- ✓Keeping the toilet, sink and shower drains where they are avoids opening the floor and moving waste lines, which is where a modest bathroom budget quietly becomes a large one.
- ✓If walls are open for plumbing anyway, adding blocking for future grab bars costs almost nothing now and is a full demolition job later. If you are already excavating or opening the basement perimeter, drainage and sump work is dramatically cheaper now than as a standalone project later.
- ✓Full-height designer tile on every wall is where bathroom budgets disappear. Tiling the wet areas properly and painting the rest looks intentional and costs a fraction as much. The City of Chicago's electrical code requires wiring in raceway rather than the non-metallic cable used almost everywhere else, which measurably raises the labor cost of any electrical scope inside city limits.
DIY vs. Hiring a Pro for a Bathroom Remodel in Illinois
Painting, fixture swaps and vanity installation are approachable; shower waterproofing is the step where amateur work fails invisibly and expensively. Since roughly 35% of the total is time rather than product, the hours you take on come straight off the quote. At 1.1x the national labor rate, every hour you take on in Illinois is worth more than it would be almost anywhere else — and so is every hour a pro spends undoing a mistake. Draw the line at structure, gas and wiring — those belong to a licensed trade whatever the arithmetic says.
Home Improvement in Illinois
Chicago's building code is entirely separate from the statewide code, with its own permitting process, inspections, and contractor licensing requirements that add complexity and cost to city projects. The city's famously strict aldermanic system means that neighborhood-level zoning decisions can affect renovation scope and timelines. Downstate Illinois offers significantly lower costs—labor rates in Springfield or Champaign run 30-40% below Chicago metro levels, with material costs tracking closer to national averages.
Climate Considerations for Illinois Projects
Illinois experiences dramatic temperature extremes, from -20°F winter lows to 100°F summer highs, creating substantial thermal stress on building envelopes and making energy efficiency a major cost driver. The state sits in a high-risk zone for ice dams, and proper attic ventilation and insulation are critical to preventing winter roof damage. Spring flooding along the Mississippi and Illinois rivers affects thousands of homes, making flood-resistant construction methods and sump pump systems common renovation components in affected areas.
Contractor Licensing in Illinois
Illinois does not require a statewide general contractor license, but Chicago and most suburban Cook County municipalities mandate local licensing with trade-specific exams, insurance requirements, and bonding. Roofing contractors statewide must register with the Illinois Department of Financial and Professional Regulation. Plumbers and electricians require state licenses with examination and apprenticeship completion, and continuing education is mandatory for license renewal.

How Our Bathroom Remodel Estimate Shifts Across Illinois Metros
Costs move from one metro to the next with local demand, contractor availability, and cost of living. The figures below are our Illinois estimate scaled by a metro index we set for each city — we have not surveyed contractors in these cities, and no one has priced your job. Read the percentages as our judgment of how far each metro sits from the statewide figure:
| City | Low | Average | High | vs State Avg |
|---|---|---|---|---|
| Chicago, IL | $8,085 | $17,325 | $40,425 | +10% |
| Aurora, IL | $7,350 | $15,750 | $36,750 | on par |
| Rockford, IL | $6,762 | $14,490 | $33,810 | -8% |
These are modeled figures, not quotes: the Illinoisestimate multiplied by our own metro index. They carry the same 30–50% bid spread as every other number on this page, and we deliberately do not publish neighborhood- or ZIP-level figures, because we have no data that fine.
Regional Considerations in Illinois
Permits & Inspections
Chicago permitting is entirely separate from the statewide system, with its own process, fees, and inspections — city projects are slower and pricier to permit than those downstate.
Local Labor Market
Chicago-metro labor runs 10-15% above the national average, while downstate cities like Springfield and Champaign can be 30-40% cheaper.
Climate & Cost Impact
Big temperature extremes and ice-dam risk make insulation and attic ventilation important cost factors.

Bathroom Remodel Cost in Illinois: FAQ
How much does a bathroom remodel cost in Illinois?
We estimate $7,350 to $36,750 for a bathroom remodel in Illinois, with a mid-scope job modeled at $15,750. That figure is our $15,000 national baseline multiplied by Illinois's 1.05 cost index, which puts it roughly 5% above our national baseline. It is a planning estimate rather than a quote — written bids commonly come in 30–50% either side of a modeled number, depending on scope, materials, and where in the state you live.
What is the biggest cost factor in a bathroom remodel?
In our bathroom remodel cost model, Labor is the largest single line item at about 35% of the total. We rate Illinois labor at 1.1x the national level, so the labor share of the job moves the most from state to state. Getting several itemized local bids is the only reliable way to pin down your own number.
Is a bathroom remodel cheaper in Illinois than the national average?
No — Illinois runs roughly 5% above the national average, with a typical bathroom remodel near $15,750. Higher local labor and material rates drive the gap.
What is the best month to schedule a bathroom remodel in Illinois?
Illinois crews fill winter with interior work, so January and February starts are usually easier to get and better priced. Tile and fixture availability, plus the number of separate trades that have to sequence through one small room, set a bathroom's timeline more than crew scheduling does. Because this is indoor work, Illinois weather affects deliveries and inspections more than it affects the job itself.
Is it cheaper to remodel a bathroom or just replace the shower?
Replacing only the shower is far cheaper, but it only makes sense if the rest of the room is in good shape and the layout works. Once you are opening walls for the shower anyway, the marginal cost of new tile, a vanity and fixtures is much lower than doing those things as a separate project — so the honest comparison is a shower now versus a full remodel now, not a shower now versus a full remodel never. Illinois licenses roofing contractors at the state level, which is unusual — a roofing license number is something you can and should verify.
How do I avoid a bad bathroom remodel contractor in Illinois?
Inside Chicago, confirm the electrician is city-licensed and the bid assumes conduit; outside it, check the municipality's own contractor requirements. Ask exactly how the shower will be waterproofed and by whom. A bathroom bid that does not name the waterproofing method — a sheet or liquid membrane system, not just cement board — is hiding the one detail that determines whether you are re-doing this room in five years.
What is the cheapest a bathroom remodel in Illinois typically runs?
Simpler or smaller projects can start around $7,350 in Illinois, though at that end you are usually accepting a tighter scope or more basic materials. The shower is the swing item in a bathroom. A drop-in tub with a surround is a fraction of the cost of a custom tiled shower with a proper waterproofing assembly and a linear drain.
