Short answer
A walk-in shower in Naperville typically costs $5,600 to $18,600 in 2026, because Naperville shares Chicago-area labor rates. Three Naperville walk-in shower permits issued in December 2025 listed project values of $20,462 to $25,000. Shower and bath remodels that touch plumbing need a city building permit before work starts.
Key facts
- Three Naperville residential alteration permits for walk-in shower jobs issued in December 2025 listed valuations of $20,462, $22,285 and $25,000, with permit fees of $343, $293 and $393.[2]
- Naperville's residential fee schedule charges remodeling permits an $18 clerical fee plus $25 per plan page, and $50 per inspection.[3]
- The median Naperville home was built in 1990, and about 75% of occupied homes are owner-occupied (Census ACS 2024 5-year).[5]
Walk-in shower cost in Naperville
Naperville is part of the Chicago-Naperville-Elgin labor market, so the same wage data drive prices here as in Chicago. In that area, plumbers earn a median $49.70 an hour and tile setters $35.90, against $30.67 and $26.77 nationally[1]. Our Chicago-area estimates adjust national prices for those wages:
| Project | Our Chicago-area estimate (2026) | Details |
|---|---|---|
| Walk-in shower | $5,600 to $18,600 | Chicago walk-in shower cost |
| Tub to shower conversion | $2,500 to $14,900 | Chicago conversion cost |
| Walk-in tub, installed | $4,100 to $12,200 | Chicago walk-in tub cost |
| Full bathroom remodel | $7,400 to $22,300 | Chicago bathroom remodel cost |
Naperville also publishes something most towns do not: a monthly list of every residential permit it issues, with the value the applicant declared. In December 2025, three permits described walk-in shower work[2]:
| Job described on the permit | Declared value | Permit fee total |
|---|---|---|
| Tub and shower combo replaced with a walk-in shower | $20,462 | $343 |
| "Like for like" walk-in shower upgrade | $22,285 | $293 |
| Primary bath: tub to walk-in tile shower, all new fixtures, door moved | $25,000 | $393 |
These are three real jobs, not an average. They sit in the upper half of our range, which fits full tile work in a primary bathroom. A prefab shower in the same spot as the old tub would usually cost less.
Permits in Naperville
The city says residents must get the necessary building permits before starting alterations to an existing home[4]. Shower and bath jobs are filed as residential building alterations; the December 2025 report lists them under that work class[2]. Applications, payments and inspection requests go through the city's Civic Access portal, and questions go to the TED Business Group at 400 S. Eagle St., (630) 420-6100[4].
Fees are set by the residential fee schedule. For remodeling in a single-family home or duplex, the city charges[3]:
- an $18 clerical fee plus $25 per plan page, paid when you apply
- $50 per inspection, paid when the permit is issued
- $68 for each reinspection if something fails
The schedule calls these a good-faith estimate, and city staff set the final count of inspections during plan review[3]. The live city website blocks automated readers, so we used archived copies of these documents. Check the current numbers with the city before you budget to the dollar.
Naperville homes and what they mean for the job
Naperville's houses are young for the Chicago area. The median home was built in 1990, and about 51% were built between 1980 and 1999[5]. Only about 26% predate 1980, and about 63% are single-family detached houses[5]. About 75% of occupied homes are lived in by their owners[5].
What that means for a shower project:
- Molded tub surrounds. One December 2025 permit replaced a one-piece fiberglass tub and surround[2]. When the old unit is a single molded piece, a shower that keeps the same footprint and drain is the simplest job to price.
- Valves from the original build. A house built around 1990 may still have its first shower valve. Many plumbers recommend replacing it during any shower remodel rather than reusing it, since the wall is already open.
- Planning to stay. If you expect to live in the home for many years, ask for blocking in the walls for grab bars and a low or no-step entry while the room is apart. Adding them later costs more.
Choosing a company in Naperville
Illinois licenses plumbers through the Illinois Department of Public Health. Plumbing contractors must register with the state each year, every plumbing ad must show the license number, and IDPH offers an online license check[6].
Questions worth asking:
- Who pulls the Naperville permit, and how many plan pages and inspections do you expect?
- Is the price for a prefab base and walls or for tile, and is the glass included?
- Will you replace the shower valve, and is that in the quote?
- What is your Illinois plumbing license number?
Illinois law also protects you on the paperwork. Before any home repair or remodeling job over $1,000, the contractor must give you a written contract stating the total cost and the business name and address[7]. If the contract includes binding arbitration or a jury trial waiver, you must be told and given the choice to accept or reject each clause[7].
When to call a pro
- Any new valve, drain or supply line: an Illinois-licensed plumber, working under a Naperville permit[4][6].
- Moving the bathroom door or a wall, as one December 2025 job did[2]: plans drawn to scale for the permit.
- Soft floor or stains on the ceiling below the bathroom: have the leak found before you choose finishes.
- Comparing prices: get at least three written quotes and hold them against the ranges above.
More questions
Do I need a permit to replace a tub with a walk-in shower in Naperville?
Yes. Naperville issues residential alteration permits for this kind of work, and recent permit reports list tub to walk-in shower jobs under that permit type. Apply through the city's Civic Access portal before work begins.
How much is a Naperville permit for a shower remodel?
It depends on plan pages and inspections. The fee schedule charges an $18 clerical fee, $25 per plan page and $50 per inspection. Three walk-in shower permits issued in December 2025 had fee totals of $293 to $393.
Is a walk-in shower cheaper in Naperville than in Chicago?
Not by much. Naperville is in the same federal wage survey area as Chicago, so labor rates are similar. The bigger difference is the house: most Naperville homes are newer than Chicago's, which can mean fewer surprises behind the wall.
