A bathroom remodel is one of the most disruptive projects you can do in a home — and one where the gap between "what I was told" and "what actually happened" tends to be largest. The shower's been out for three weeks. The dust has spread to three rooms. The tile still isn't here.
Understanding the real timeline before you start makes the process far less stressful. Here's an honest week-by-week breakdown based on full bathroom remodels we've completed in Naperville, Downers Grove, Lisle, and the surrounding suburbs — not a best-case scenario, but what a well-run project actually looks like.
Before Week 1: Design, Selections, and Permits
The weeks before demo are the ones most homeowners underestimate. If you make fixture selections and tile choices after work has started, the project stalls while you wait for materials. If permits aren't pulled before demo, you're not legally allowed to start structural or plumbing work in most DuPage and Will County municipalities.
The pre-construction phase for a full bathroom remodel typically takes 3–6 weeks and includes:
- Design finalization — Layout decisions, fixture selections, tile choices, lighting plan
- Material procurement — Ordering tile (especially large-format or imported tile), vanity, shower fixtures, and anything with a lead time longer than a week
- Permit application — Required for plumbing changes, electrical work, and structural modifications in virtually every municipality in the area. Naperville building permits typically process in 1–2 weeks for straightforward residential projects; Wheaton and Lisle are similar. Plan for the possibility of one revision cycle.
The most common source of project delay we see isn't the contractor — it's selections made late. If you want a specific Italian tile, a custom vanity, or a discontinued fixture model, those decisions need to happen before demo begins. Start shopping early.
Week 1: Demo and Rough-In Inspection Prep
Demo goes faster than people expect — a full bathroom demo is often a day or two of work. But what demo reveals determines what happens next.
Common discoveries in older western suburbs homes:
- Failed waterproofing behind existing tile — Cement board that's been wet for years, framing that's soft or beginning to rot, mold in the wall cavity
- Lead paint or asbestos — Common in homes built before 1978 and 1980 respectively; requires proper handling and disposal
- Outdated galvanized or cast iron drain lines — Older homes in Geneva, Wheaton, and Aurora frequently have original drain plumbing that's worth replacing while the walls are open
- Insufficient electrical — Bathrooms now require GFCI protection on all circuits, and older homes often have bathroom circuits that don't meet current code
None of these are disasters, but each adds time and cost. A contractor who walks a bathroom pre-demo and tells you exactly what they expect to find is more trustworthy than one who gives you a firm price without looking at what's behind the existing tile.
By end of week one, rough-in plumbing and electrical should be complete or underway — new drain positions confirmed, supply lines roughed in, electrical circuits run. Rough-in inspection happens at the end of this phase before walls close up.
Week 2: Waterproofing, Backer, and Board
After rough-in passes inspection, walls get prepped for tile. This phase — shower pan waterproofing, cement board installation, waterproof membrane application — is the most critical work in a bathroom remodel and the least glamorous.
Shower waterproofing failures are the leading cause of expensive bathroom repairs. A leak that develops behind tile doesn't announce itself for months or years — by the time it shows up as a stain on the ceiling below or a musty smell in the space, the damage is already significant.
We use linear-drain shower systems and liquid membrane waterproofing on all wet areas — products like Schluter Kerdi or RedGard applied to manufacturer specifications, with corner treatments and drain connections done correctly. We also flood-test pans before tiling. It's a step some contractors skip. We don't.
Vanity rough-in (electrical outlets, plumbing rough-out to finished wall height) also happens this week. Exhaust fan blocking gets installed. Any heated floor elements go in before tile substrate.
Weeks 3–4: Tile and Fixtures
Tile work is where the transformation becomes visible — and where timeline variation is highest. A simple 60" x 36" shower with subway tile takes a day and a half to tile. A large walk-in shower with large-format 24×48 porcelain, a built-in bench, a niche, and a floor with a linear drain pattern takes four or five days. Floor tile throughout, decorative borders, and custom patterns add more.
After tile is set, it needs to cure before grouting — typically 24 hours minimum, often 48 for large-format tile or heated floor systems. After grouting, sealant needs to cure before the shower can be used — usually another 24–72 hours depending on product.
Fixture installation — shower valves, handheld fixtures, shower heads — happens after tile is complete. Vanity installation, toilet, and mirror follow. By end of week four on a typical full bath, the space is beginning to look finished.
Week 5: Trim, Paint, and Punch List
The final week is finish work: painting, trim installation, accessory mounting (towel bars, toilet paper holder, hooks), light fixture installation, mirror mounting, and final plumbing connections (supply lines to vanity, toilet supply and wax ring, shower trim). Final electrical (GFCI outlets, exhaust fan wiring) happens here too.
Final inspection follows when the scope requires it — any permitted plumbing or electrical work will require a final inspection before the permit closes. In Naperville and most DuPage County municipalities, scheduling the final inspection can take a few days. Plan for it in the timeline.
The punch list walk happens after final inspection: we walk the space with the homeowner, document anything that needs attention, and complete those items before closing out the project. A thorough punch list at week five is far better than discovering items six months later.
What Extends Timelines
Real projects hit real complications. The ones that extend timelines most often:
Material back-orders. Tile ordered from a warehouse that turns out to be out of stock. A vanity with an 8-week lead time you didn't know about. A specialty shower fixture that ships from overseas. If there's any chance a specific material has a long lead time, find out before demo begins — not after.
Subcontractor scheduling. If your GC coordinates a separate licensed plumber and separate licensed electrician who have their own schedules, gaps develop between phases. We prefer tight coordination with subs we work with regularly precisely to avoid this.
Permit delays. Municipal building departments vary in their processing speed. Naperville is generally efficient. Some smaller municipalities in the area run slower. Factor in buffer for permit processing and inspection scheduling.
Change orders mid-project. Changing tile selection after it's been ordered, deciding to add a heated floor after the substrate is installed, upgrading the vanity after the rough-in is set — these all add time and sometimes cost. Changes are a normal part of any project, but front-loading decisions minimizes their impact.
Primary Bath vs. Hall Bath: Timeline Differences
The timeline above reflects a full primary bathroom renovation — typically 60–120 square feet with a separate tub and shower, double vanity, and some level of design complexity.
A hall bathroom or powder room renovation runs faster: 2–3 weeks for a full hall bath gut renovation, 1–2 weeks for a powder room. Smaller footprint, simpler plumbing, less tile work.
Adding a bathroom where one didn't exist — converting a closet or unused space to a full bath — adds time for structural work, running new supply and drain lines, and potentially opening adjacent walls. Budget 6–10 weeks for a conversion project of this type in the western suburbs.
Frequently Asked Questions
Do I need a permit for a bathroom remodel in Naperville or DuPage County?
Yes, for most meaningful bathroom work. Any plumbing changes (moving or adding fixtures, relocating drains), electrical work (new circuits, additional outlets, exhaust fan additions), and structural modifications require permits in Naperville and virtually all DuPage and Will County municipalities. Purely cosmetic replacements — swapping an existing toilet, replacing a vanity in the same location with the same plumbing connections — generally don't require permits, but confirm with your city's building department if you're unsure.
How much does a bathroom remodel cost in the western suburbs of Chicago?
A full hall bathroom renovation in DuPage County typically runs $18,000–$40,000. A primary bathroom renovation with a custom tile shower, double vanity, freestanding tub, and quality fixtures typically runs $35,000–$80,000. High-end primary baths with heated floors, custom glass enclosures, steam systems, and luxury fixture brands can exceed $100,000. Labor in the western suburbs is priced at current market rates for the area — budget based on what's actually done here, not national averages.
Can I use my bathroom during a remodel?
If you only have one bathroom, this is a critical planning question. During a full gut renovation, the bathroom is completely unusable — no toilet, no shower, no sink. If you have a second bathroom, plan to use it exclusively. If you don't, options include a temporary toilet in an adjacent space, staying elsewhere for the duration, or phasing the work. We talk through this explicitly during project planning for any single-bathroom home.
What's the ROI on a bathroom remodel in Illinois?
Bathroom renovations in the Chicago suburbs consistently show positive ROI relative to renovation cost, particularly for primary baths in homes where the existing bath is significantly dated. Remodeling Magazine's annual Cost vs. Value report shows midrange bathroom additions and renovations recovering 55–70% of cost on resale in the Chicago metro. The non-financial return — living in a space you actually like — is harder to quantify but real.
How do I choose tile that won't look dated in five years?
The trends that age worst are the ones chasing the moment hardest. The tile choices that hold up: large-format neutral porcelain in the shower (24×48 or 12×24 in warm whites, soft grays, or natural stone looks), simple rectangular or square floor tile with a contrasting or coordinating grout, and limiting accent tile to one specific element rather than covering every surface. Bold choices — zellige tile, handmade texture, strong color — hold up better than you'd expect because they're interesting rather than trendy. The thing that ages worst is whatever was ubiquitous in that particular year.
