Small Bathroom Remodeling in Chicago
A small bathroom leaves little room for mistakes, because every inch of floor, wall and ceiling is doing a job. Published planning figures vary widely: Block Renovation says a basic full-bath remodel in Chicago starts around $16,000, while Angi’s national average for a small bathroom is about $6,500. Your own price depends on scope, so tell us about the project and we will match you with up to three independent licensed remodelers who can give you a written scope and price to compare.

What counts as a small bathroom
There is no legal size. Block Renovation describes a Chicago powder room as 20 to 30 square feet and a full bath as 40 to 100 square feet, while Angi counts a 30-square-foot room with a tub or shower as a small full bath. The benchmark room in the Cost vs. Value report is a 5 by 7 foot bath built around a 30 by 60 inch tub.
Small rooms cost less in total but not per square foot. The same trades still show up: demolition, plumbing, tile, electrical and finish work. Angi puts labor at 40% to 60% of a small bath budget.
| Project | Planning range | Source and scope |
|---|---|---|
| Powder room, Chicago | $5,000 to $15,000 | Block Renovation |
| Full bathroom, Chicago | Starts near $16,000; up to about $30,000 | Block Renovation |
| Midrange update of a 5×7 ft bath, Chicago | $24,072 | Cost vs. Value 2025 |
| Small bathroom, national | $1,500 to $15,000; average about $6,500 | Angi |
| Small full bath (about 30 sq ft), national | $4,500 to $6,000 | Angi |
The national figures run well below the Chicago ones, and Angi’s small-bath numbers cover everything from a vanity swap to a full gut. Read the scope before you compare. For the Chicago breakdown, see our small bathroom remodel cost guide.
What to plan before you start
Keep the fixtures where they are, if you can
Moving plumbing is the fastest way to grow a small-bath budget. Block Renovation lists moving a toilet at roughly $1,500 to $3,500, a sink at $500 to $1,500, and a shower or tub at $1,000 to $5,000 or more. In a room this small, a better vanity, smarter storage and good lighting often do more for daily use than a new layout.
Check clearances before you pick fixtures
The National Kitchen & Bath Association’s planning guidelines are a useful checklist. They suggest a clear opening of at least 34 inches for a single doorway, which takes a 36-inch door, and clear floor space of about 30 by 48 inches at each fixture. A narrower vanity can free floor space, but it gives up counter and storage. Measure first, then choose.
Tub, shower or both
Angi notes that bathtub-shower combinations are the most practical choice in a small full bath because they save floor area, and that a home with no tub at all can hurt resale, especially for buyers with young children. If you want a shower only, read about tub-to-shower conversion.
Storage and lighting
A recessed medicine cabinet, a taller vanity with drawers and wall niches in the shower all add storage without taking up floor. For lighting, the NKBA guidelines suggest a ceiling or recessed light over the front edge of the toilet, lighting at the mirror that lights the face, and no surface-mounted or decorative fixtures inside a shower. Switches and outlets should sit at least 39 inches from the edge of a tub or shower, and every bathroom outlet should have ground-fault (GFCI) protection.
Ventilation
Small rooms hold moisture. The NKBA suggests a fan rated at 60 cubic feet per minute or more. Chicago’s Building Code calls for a mechanical exhaust system in bathrooms, and the Chicago Mechanical Code says exhaust air must discharge outdoors, not into an attic or crawl space. Ask each remodeler where the fan will vent.
Old pipes and lead paint
Once the walls are open, older Chicago buildings can turn up worn supply or drain pipes. Ask every remodeler how they handle what they find. If your home was built before 1978, federal EPA rules require firms paid to disturb paint to be RRP certified. See bathrooms in Chicago bungalows, greystones and two-flats and lead-safe remodeling in pre-1978 homes.
Condo and two-flat bathrooms
Most condo buildings set rules for work hours, elevators and insurance, and a leak in a small bath can reach the unit below. Ask your association what approval it needs before you plan. In a two-flat, a bathroom may sit above or below the other unit’s, so tell both households. Read remodeling a condo bathroom in Chicago, then see Lake View and Portage Park for neighborhood notes.
Permits and licenses in Chicago
A small bath remodel that replaces or moves plumbing, or changes wiring, needs a City of Chicago permit. Non-structural interior work in one dwelling unit may qualify for the Express Permit Program, which allows plumbing that adds up to 5 water supply fixture units and does not allow adding, removing or reconfiguring walls or doors without drawings from an Illinois-licensed architect or structural engineer. The stand-alone fee is $250 for work up to 500 sq ft. Painting, new tile and cabinets without plumbing or electrical connections do not need a permit.
Chicago requires a licensed general contractor for most remodeling, and licensed plumbing and electrical contractors for those trades. The remodelers we match you with are independent companies, so check each license before you hire.
How to get a fair comparison
- Write down what stays and what moves. A remodeler can only price the same scope if each one gets the same list.
- Ask for a written scope and price from each remodeler that lists materials, labor, the permit, waterproofing and an allowance for hidden conditions.
- Ask who does the plumbing and electrical work, and verify those licenses too.
- Read the contract. Illinois law requires a written contract for home remodeling work over $1,000.

Frequently asked questions
How much does a small bathroom remodel cost in Chicago?
Block Renovation says Chicago powder rooms run about $5,000 to $15,000 and basic full baths start near $16,000. Angi's national average for a small bathroom is about $6,500, which includes minor jobs. These are planning ranges, not a quote.
What is the best way to save money on a small bathroom?
Keep the toilet, sink and tub or shower where they are. Block Renovation lists moving a toilet at roughly $1,500 to $3,500 and a shower or tub at $1,000 to $5,000 or more. Better storage and lighting often change daily use more than a new layout.
Do I need a permit to remodel a small bathroom in Chicago?
If the job replaces or moves plumbing or changes wiring, yes. Painting, tile and cabinets without plumbing or electrical connections do not need one. Many single-unit jobs may use the Express Permit Program, which does not allow changing walls or doors.
How much clearance does a small bathroom need?
The NKBA guidelines suggest a clear doorway opening of at least 34 inches and clear floor space of about 30 by 48 inches at each fixture. Your building may limit what is possible, so measure before you choose fixtures.
Do I need a bathroom fan?
Chicago's Building Code calls for mechanical exhaust in bathrooms, and the Chicago Mechanical Code says the air must discharge outdoors, not into an attic or crawl space. The NKBA suggests a fan rated at 60 cubic feet per minute or more.
Should I keep the tub in a small bathroom?
Angi says tub-shower combinations are the most practical choice in a small full bath, and that a home with no tub at all can hurt resale. If you have another bathroom with a tub, the question is smaller.
Can I remodel a small condo bathroom?
Usually, with your association's approval. Many buildings set rules on work hours, elevators and insurance, and a leak can reach the unit below. Ask your association what it requires before you plan.
