A bathroom remodel is one of the most disruptive renovations you can run inside a lived-in Chicago home. Done right, it adds value, fixes water problems before they become structural, and gives you a space you actually enjoy. Done wrong, it costs more than the original estimate, drags on for months, and leaves you with hidden defects that show up after the contractor is gone.
Most of that downside is avoidable. The clients who have the smoothest projects are the ones who walk in knowing what to expect, prepare their home properly, and ask the right questions before they sign a contract. This guide covers all three, plus a section on the difference between a general contractor (GC) and a subcontractor, which is one of the most common points of confusion we hear from Chicago homeowners.
What to Expect From a Chicago Bathroom Remodel
A typical full bathroom remodel in Chicago runs 3 to 6 weeks of active on-site work, after a 2 to 6 week design and procurement phase. The phases are not negotiable. Skipping any of them is how projects go off the rails.
Phase 1: Consultation and scope. Initial phone call, on-site walkthrough, scope conversation. The contractor should be measuring, taking photos, asking about how you use the space, and flagging anything they see that affects the budget (slope of floor, age of plumbing, ventilation, structural).
Phase 2: Design and selections. Fixtures, tile, vanity, lighting, hardware, paint. This phase is where most homeowner-driven delays happen. If you have not picked tile by the day demo starts, the project will stall.
Phase 3: Written estimate and contract. Itemized estimate on contractor letterhead, with the license number, address, scope of work, materials allowance, payment schedule, and timeline. Signed by both parties before any deposit changes hands.
Phase 4: Permits. For anything that moves a wall, changes plumbing routing, or adds electrical circuits, Chicago requires permits pulled through the Department of Buildings. A licensed GC pulls these. Unlicensed contractors do not.
Phase 5: Demolition and rough-in. Tear-out, framing changes, plumbing rough-in, electrical rough-in, ventilation. This is the dustiest, loudest part of the project.
Phase 6: Inspections and waterproofing. Rough-in inspections by the city, then waterproofing of the wet zones (shower pan, walls, niches). This is the single most important phase for the long-term durability of the bathroom. Waterproofing should be photo-documented.
Phase 7: Tile, finishes, fixtures. Tile setting, vanity install, plumbing trim, electrical trim, paint, hardware. The bathroom starts looking like a bathroom again.
Phase 8: Punch list and final walkthrough. Last 5 percent of the work, the part that separates a finished bathroom from a "mostly done" bathroom. Walk the room with the contractor, write down anything that needs adjustment, and confirm the final payment is tied to that list being closed.
What you should expect day-to-day during active construction:
- Daily disruption. Dust, noise, water shutoffs, materials in your hallway.
- Crew on site by 8 AM, gone by 4 to 5 PM on a typical day. Weekend work only with your written consent.
- A single point of contact (the project manager or the owner) who you can call or text with questions.
- Photos of work that gets covered up. Waterproofing, plumbing behind tile, electrical inside walls. You should not have to ask.
- Honest timeline updates when something slips. Delays happen. The contractor's job is to tell you immediately and re-baseline the schedule, not to hide it.
How to Prepare Your Home
The bathroom remodel itself is a few weeks. Living through it without losing your mind is a separate skill. Here is how to set the project up so it does not consume your daily life.
Set up a backup bathroom. If you are remodeling your only bathroom, you need a plan: a neighbor, a relative, a gym membership with showers, or a temporary rental. Do not assume the contractor will work miracles to keep the toilet alive. They cannot.
Move every bathroom item out before demo day. Toiletries, towels, hampers, medications, the back of the under-sink cabinet that has not been opened in five years. All of it. Anything left in the room on day one will either get covered in dust or thrown out.
Protect adjacent rooms. A good contractor lays floor protection in the hallways and uses zip walls to contain dust. You can help by closing doors to bedrooms and closets, removing artwork from shared walls, and covering anything sensitive in nearby rooms.
Plan for kids, pets, and noise. Saws, hammer drills, and tile cutters are loud. If you work from home, you will hear them. If you have a dog that barks at strangers, the dog will bark for 3 weeks. Think about this before demo, not on day 3.
Pre-stage all your selections. Tile, vanity, mirror, lights, hardware, paint, faucet, showerhead, toilet, exhaust fan. All of it should be ordered, delivered, and on site (or on a confirmed delivery date) before demo starts. The single biggest cause of mid-project delays is a back-ordered fixture nobody confirmed.
Set communication expectations. Daily text update vs. end-of-week call. What hours the crew can reach you. Who can sign off on a small change order vs. who has to be the homeowner. Lock this down in the contract, not on day 5 by accident.
Pull your money lined up. Bathroom remodels in Chicago are typically paid in 3 to 4 milestones: deposit, mid-project draw, substantial completion, final after punch list. Make sure each draw is available before it is due. Holding up a draw to a tile sub mid-job is how you lose your installer.
10 Questions to Ask Your Contractor Before You Sign
A licensed and reputable Chicago contractor will answer every one of these without flinching. If a contractor hedges, deflects, or gets annoyed, that is the answer.
1. What is your Illinois GC license number, and can I look it up?
The answer should be a specific number, and you should be able to verify it on the Illinois Department of Financial and Professional Regulation (IDFPR) public lookup. AAA Construction Services license number is TGC119698.
2. Are you insured, and can you send me a current Certificate of Insurance?
General liability and workers comp. The COI should be issued directly from the contractor's insurance carrier, name AAA Construction Services LLC (or whichever company), and list current coverage dates. Anyone who cannot produce one in 24 hours should not be on your short list.
3. Will you pull the permits yourself, or am I expected to pull them as the homeowner?
A licensed GC pulls permits themselves and is the responsible party on record with the city. Asking the homeowner to pull permits is a red flag - it usually means the contractor is unlicensed or trying to keep their name off the city record.
4. Can I see your written estimate, and will the contract match it line by line?
The estimate should be on letterhead, itemized, list the license number, list materials allowances, list the payment schedule, and list the timeline. The contract should reference that estimate directly.
5. Who will be on site every day, and who is my single point of contact?
You should know the project manager and the lead carpenter by name. You should know who is in charge when the owner is not on site. You should have a direct phone number, not a generic office line.
6. Are the people doing the work your employees, or subcontractors?
There is no wrong answer to this - most GCs use a mix - but you should know which trades are in-house and which are subbed out. Tile, plumbing, electrical, and waterproofing are the trades worth asking about specifically.
7. How do you handle change orders?
Change orders should be written, signed, priced, and dated before the work happens. Verbal change orders are the number one cause of disputed final invoices. Ask to see a sample change order.
8. What is your warranty, and what does it cover?
Workmanship warranty (the contractor's labor) and manufacturer warranty (the fixtures and materials) are different. The contractor should clearly explain both, and the workmanship warranty should be written into the contract.
9. Can I see 3 references from completed projects in the last 12 months, and can I visit a job in progress?
Recent references matter more than old ones. A current job site visit shows you how the crew protects the home, manages dust, and treats the homeowner during construction - not just the polished after photo.
10. What payment schedule do you use, and what triggers each payment?
Reasonable schedule for a Chicago bathroom remodel: deposit on signing (15 to 25 percent), mid-project draw after rough-in inspection passes, substantial completion draw at start of finish work, final payment after punch list is closed. Beware anyone asking for 50 percent or more upfront.
General Contractor vs Subcontractor: What's the Difference?
This is the single biggest source of confusion we see when homeowners are shopping a remodel. The two roles are completely different.
A general contractor (GC) is the company you hire. The GC signs the contract with you, pulls the permits, runs the project schedule, hires and pays the trades, manages the inspections, handles the warranty, and is the legally responsible party on the job. A GC in Illinois is licensed by the state (license numbers start with "TGC" for Chicago contractors). AAA Construction Services is a licensed Illinois GC; our license is TGC119698.
A subcontractor (sub) is a specialist trade hired by the GC, not by you. The plumber, electrician, tile setter, drywaller, and HVAC tech on a bathroom remodel are typically subcontractors. They have their own trade licenses (plumbers and electricians in Illinois are licensed independently), but they work under the GC's contract with you. You do not pay them directly, you do not coordinate their schedule, and you do not pursue them for warranty work - all of that goes through the GC.
Why this matters for the homeowner:
| Question | General Contractor | Subcontractor |
|---|---|---|
| Who do I sign a contract with? | Yes, you sign with the GC | No, the GC signs with the sub |
| Who pulls the permit? | The GC | Trade subs may pull their own trade permits (plumbing, electrical) under the master permit, but the GC is responsible |
| Who do I pay? | You pay the GC | The GC pays the sub |
| Who do I call with a problem? | The GC | The GC, not the sub directly |
| Who is responsible for the warranty? | The GC | The GC backs the work; the sub backs it to the GC |
| Who is licensed? | The GC holds the master license | Trade subs hold their own trade-specific licenses |
A few practical implications for your project:
- Never hire a sub directly to save money on a multi-trade project. If you hire the plumber yourself and the electrician yourself and the tile guy yourself, you are now the GC. You are responsible for coordinating the schedule, sequencing the trades, pulling permits, and handling disputes between trades when one blames the other. That is a full-time job, and if anything goes wrong, the legal exposure is yours.
- Be cautious of a "contractor" who is actually one trade. A tile setter calling themselves a "bathroom remodeling contractor" is not the same as a licensed GC. They can do the tile beautifully and still leave you exposed on permits, plumbing, electrical, and waterproofing coordination.
- Ask which trades are in-house vs. subbed out. Most legitimate Chicago bathroom GCs sub out at least plumbing and electrical, because those require their own state licenses. That is normal and not a red flag. What matters is that the GC takes responsibility for all of it.
A Realistic Mindset Before You Start
Remodels are not movie montages. There will be a dusty week, a delayed-fixture week, and a "wait, that grout color looks different from the sample" moment. The way you avoid the bad version of a remodel is by hiring a licensed GC, getting everything in writing, preparing the house, and asking questions before the contract is signed instead of after the demo is done.
