Bathroom Remodel Timeline 2026: Chicago Suburbs Scope-by-Scope Guide

The question most homeowners ask first is "how long will this take?" The accurate answer depends entirely on one prior question: what scope are you actually doing?

A cosmetic refresh and a full gut bathroom are both called "bathroom remodels." They take different amounts of time for completely different reasons. The schedule for each scope tier in the Chicago suburbs in 2026 is below.

Our bathroom remodeling services page and the Highland Park service area page describe what each scope tier involves in specific local conditions.

Scope Tier 1: Cosmetic Refresh (1-3 Weeks Total)

A cosmetic refresh keeps all fixtures - toilet, tub, shower, and vanity - in their existing locations. No plumbing moves. No permit is required in most Chicago suburbs when scope is limited to this level.

What a cosmetic refresh includes: new flooring over existing substrate (vinyl plank is the practical choice for an overlay application), fresh paint, new lighting with the same box location, hardware replacement, a new vanity top without moving the drain, a new toilet in the same rough-in location, and possibly new tile on a shower surround if the existing substrate is sound.

What it does not include: removing existing tile from walls or floors, replacing the tub or shower pan, touching any supply or drain lines, or moving any fixture.

Timeline breakdown:

• Material procurement: 1-2 weeks if selections are standard and in-stock
• Active work: 3-7 business days
• Total: 1-3 weeks

The 3-week end of this range applies when a selected item is not immediately available or when a minor unexpected condition - a shower valve that needs replacement while accessible - adds a day or two. This tier rarely runs long.

Scope Tier 2: Mid-Range Renovation (6-10 Weeks)

A mid-range bathroom renovation replaces tile, the tub or shower pan, vanity, toilet, and all fixtures, all within the existing layout. Plumbing rough-in locations stay in place. This is the most common bathroom scope in the Chicago suburbs.

A permit is typically required in North Shore municipalities when this scope involves opening walls for new plumbing connections, replacing the tub with a shower (which changes rough-in), or replacing electrical at the panel level. Like-for-like fixture replacements in the same location may not require a permit in some jurisdictions, but confirm with the specific village building department before assuming.

Timeline breakdown:

• Design and material selection: 2-4 weeks
• Permit application and review (if required): 2-4 weeks for suburban Chicago villages; overlap this with design
• Demolition: 2-4 days
• Rough-in inspection (if permitted): 2-5 business days after rough-in is complete
• Tile work: 1-2 weeks (waterproofing membrane cure time is 24-72 hours before tile can be set - this is not a shortcut-able step)
• Vanity and fixture installation: 2-4 days
• Frameless shower glass: measured after tile is complete; ships 2-4 weeks later - this routinely holds the punch list
• Final inspection and punch list: 3-5 business days

Total: 6-10 weeks from first demolition day to usable bathroom. Add 2-4 weeks for permit review if it runs concurrently with design rather than ahead of it.

The frameless shower glass timeline is the most consistent schedule surprise in this scope tier. The glass cannot be templated until tile is complete and grout is dry. It then takes 2-4 weeks to fabricate and ship. Homeowners who are living in the home during the remodel often have a functional shower before the glass arrives but cannot use it with a door until the final week.

Scope Tier 3: Full Gut with Layout Change (10-18+ Weeks)

A full gut bathroom with a layout change - moving plumbing, reconfiguring walls, or expanding into adjacent space - is a construction project in the original sense. Everything comes out. The subfloor is exposed and assessed. Walls go to studs. Plumbing rough-in is relocated. Electrical circuits are rerouted.

In the City of Chicago proper, standard plan review for this scope runs 7-9 weeks, per industry sources. Expedited review costs $500-$1,500 extra. In suburban North Shore villages - Highland Park, Northbrook, Wilmette, and the surrounding municipalities - permit review typically runs shorter for purely interior residential work, but processing times should be confirmed directly with each village building department before finalizing a project schedule. The City of Highland Park Community Development Department, for example, now intakes building permits through the Civic Access Portal, which has changed the submission process; current turnaround times should be verified there.

Timeline breakdown:

• Design, structural engineering if needed, material selection: 4-8 weeks
• Permit application and plan review: 2-7 weeks (overlap with material procurement)
• Demolition: 3-5 days
• Subfloor inspection and any structural repair: 3-10 days (subfloor rot under the tub is the most predictable find in pre-1970 homes; bathroom subfloor replacement runs approximately $700-$3,500)
• Rough-in: plumbing and electrical rough-in 1-2 weeks; rough-in inspection 2-5 business days after
• Waterproofing and substrate: 3-5 days including membrane cure time
• Tile work: 1.5-3 weeks depending on coverage and pattern complexity (herringbone and mosaic add 30-50% to tile labor time)
• Vanity, fixtures, and accessories: 3-5 days
• Frameless shower glass: 2-4 weeks after tile complete
• Final inspection and punch list: 3-7 business days

Total: 10-18 weeks from first demolition day to usable finished bathroom. Projects that encounter hidden conditions during demolition - subfloor rot, mold behind tile-over-drywall, galvanized supply that was not visible in the pre-demo assessment, or a load-bearing wall where the homeowner wanted an opening - add 1-3 weeks for the remediation work before finish trades can proceed.

Material Lead Times That Drive the Schedule

Three materials consistently determine when a bathroom remodel actually finishes:

Tile. In-stock tile is available immediately. Special-order or imported tile runs 4-6 weeks; large-format specialty tile 8-12 weeks. The practical answer is to finalize tile selection before demolition starts and order it then, so it arrives while rough-in is in progress rather than after. Tile on-site before the waterproofing membrane goes down eliminates weeks of waiting.

Vanity. Stock vanities ship in 1-2 weeks. Semi-custom runs 4-8 weeks. Custom cabinetry-style vanities run 6-10 weeks. A bathroom that is waiting for its vanity has tile done, plumbing roughed in, and fixtures installed - but cannot close out the punch list. Select the vanity in the design phase and order it early.

Frameless shower glass. This one consistently surprises homeowners because it is the last thing that goes in, it cannot be measured until tile is complete, and it then takes 2-4 weeks to fabricate. The frameless shower enclosure holds the final inspection in most bathroom projects. Budget that window into the schedule from the start.

Hidden Conditions in Pre-1970 North Shore Homes

The 6-10 week mid-range and 10-18+ week full gut timelines above assume the structure behind the walls is as expected. In pre-1970 homes across Highland Park, Northbrook, Wilmette, and the older North Shore communities, that assumption fails on a meaningful share of full gut projects.

The most common schedule-extending discoveries:

• Subfloor and joist rot under the tub. Slow leaks from a deteriorated tub flange or compression fitting saturate the subfloor over years. The extent is not visible until the tub comes out. Replacement adds $700-$3,500 and 3-7 business days to the schedule.

• Mold behind tile-over-drywall. In pre-1970 bathrooms, tile was commonly set over standard drywall (not cement board). When water infiltrates grout lines, the drywall wicks moisture and mold develops behind the tile. Remediation adds 2-5 days before new substrate goes in.

• Galvanized supply pipes. Galvanized supply corrodes from the inside over 40-50 years, reducing flow and potentially releasing lead particles from homes that previously had lead service lines, per the EPA. Replacement at the bathroom location adds 1-3 days depending on the run length.

• No mechanical exhaust, or exhaust vented into the attic. The IRC requires a minimum 50 CFM bathroom exhaust fan vented to the exterior. Attic-vented fans are a code violation and must be corrected. Rerouting the duct to an exterior penetration adds 1-2 days and a small material cost.

A 15-20% schedule buffer on a full gut project is as important as a 15-20% cost contingency.
