Local considerations
Planning bathroom remodeling in Chicago
Shared plumbing in multi-unit buildings
About 27% of Chicago housing units are in two- to four-unit buildings and about 20% are in buildings with 50 or more units. In these buildings, drain and vent lines can serve more than one unit, so water shutoffs and repairs need coordination with neighbors or building management.
Licensed plumbing and the state code
The Illinois Plumbing Code applies statewide, and IDPH licenses plumbers and registers plumbing contractors. Ask any contractor who will do the plumbing, and check that person's license with IDPH's verification tool.
Exterior walls and winter
Winter snowfall in Illinois is heaviest in the Chicago area, boosted by lake-effect snow from Lake Michigan. If a bathroom project opens an exterior wall, schedule that phase for milder weather and plan insulation and air sealing to meet the energy code that applies to your permit.

Permits
Bathroom work that moves or adds plumbing, adds electrical circuits or fixtures, changes ventilation or alters walls commonly needs a permit and inspections. Replacing a vanity or toilet in the same location may not. Rules differ by jurisdiction, so the local building department confirms what is required for your project.

Common options
- Tub, shower or both
- Keep a tub for bathing, convert to a walk-in shower for easier access, or install a tub and shower combination.

- Vanity style
- Freestanding, wall-hung or built-in, with one or two sinks, sized to the storage you need and the space around it.
- Accessibility features
- Grab bars, a handheld shower, a bench, lever handles and a comfort-height toilet can be installed now or planned with wall blocking for later.
What this service does not cover
- Remediation of widespread mold, which is handled by remediation specialists
- Asbestos or lead-based paint abatement, which is handled by certified specialists
- Replacing main water or sewer lines outside the bathroom
- Repairs to water damage in rooms below the bathroom, unless added to the scope in writing
Budget planning
What affects cost
Layout changes
Moving the toilet, shower or drains means more plumbing and floor work than keeping fixtures in place.
Shower type
Custom tiled showers with niches, benches or curbless entries take more labor than prefabricated units.
Tile selection
Tile size, material, pattern and how much of the walls are covered all affect labor and materials.
Subfloor and framing condition
Water-damaged subfloor or framing has to be repaired before new finishes can go in.
Ventilation
Adding or rerouting an exhaust fan so it vents outdoors can require work through walls, ceilings or the attic.
Fixtures and glass
Shower valve types, specialty fixtures and custom glass doors vary widely.
Access and staging
Tight rooms, upper floors and homes with only one bathroom affect how the work is sequenced.
Scheduling
What affects the schedule
- Whether this is the only bathroom in the home
- Custom shower glass, which is measured after tile is complete
- Special-order vanities, tile and fixtures
- Inspection timing for plumbing and electrical rough-in
- Drying and curing time for waterproofing, mortar and grout
- Water damage found after demolition
How to prepare
- If this is your only bathroom, arrange another place to shower during the key stages
- Remove toiletries, towels, rugs and anything stored in the vanity
- Choose tile, vanity and fixtures early so they arrive before demolition
- Note any current leaks, ceiling stains in the room below, or soft spots in the floor
- Think about future needs, such as grab bars or a step-free shower
Process
How Bathroom Remodeling Projects Work
- 1
Consult
We look at the room, check for signs of leaks and soft spots in the floor, and talk through who uses the bathroom and how. Storage and accessibility needs come up here.
- 2
Plan
We settle the layout, tub or shower, tile, fixtures and ventilation, and write down the scope. Fixtures and tile are selected and ordered before demolition so the room is not left open waiting on materials.
- 3
Build
Demolition, plumbing and electrical rough-in, and inspections come first. Waterproofing is installed and checked before tile covers it, followed by fixtures, glass and trim.
- 4
Enjoy
A final walkthrough covers how fixtures and the fan work and how to care for grout, stone and glass. Punch-list items are completed before closeout.
Questions
Bathroom Remodeling in Chicago: FAQs
Can a bathroom remodel in a Chicago condo start right away?
Check with your association first. It may have rules on work hours, insurance certificates and water shutoffs. The city also requires a permit before most construction and repair work, and the permit type depends on the scope. We confirm both during planning so the start date holds.
Can I convert my tub to a walk-in shower?
In most bathrooms, yes. The drain location, floor framing and wall conditions decide how simple it is. A low or curbless entry takes more floor work than a shower with a standard curb.
Why does waterproofing matter if tile resists water?
Grout and many tile materials let some water pass through over time. A waterproofing layer behind the tile keeps that water out of the walls and subfloor, where it would otherwise cause rot and mold.
Do I need a bathroom exhaust fan?
A fan that vents outdoors removes moisture that would otherwise collect on walls, ceilings and inside cabinets, leading to peeling paint and mold. Whether a fan is required depends on local code and whether the room has a window that opens.
