The cost to add a bathroom in Evanston ranges from $13,580 to $56,600, with most homeowners paying around $28,300. Your actual cost depends on several factors specific to your home and the Chicago-Naperville market.
A full bathroom with shower/tub costs roughly twice what a half bath (toilet and sink only) costs due to additional plumbing, tile, and fixtures.
Adding a bathroom near existing plumbing (above or adjacent to a kitchen or other bathroom) significantly reduces pipe routing costs.
Tile floors in bathrooms cost more to install than vinyl or laminate but offer better water resistance and durability in wet areas.
Basic fixtures (toilet, vanity, tub) start around $500 total while mid-range sets run $1,500–$3,000 and high-end can exceed $5,000.
Building code requires exhaust ventilation in all bathrooms — adding a vent fan with ductwork to the exterior costs $200–$500.
The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.
Budget $240–$960 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Freeze protection is critical here. Budget for pipe insulation, heat tape on exposed runs, and deeper trenching below the frost line. Winter plumbing work typically costs more due to frozen ground conditions.
This project requires a licensed professional in Evanston. Attempting bathroom addition without proper licensing can void insurance and create serious safety hazards.

Yes — adding a full bathroom typically increases home value by $20,000–$40,000, with a return on investment of 50–60%. A half bath addition returns even more per dollar spent since it costs less. Homes with one bathroom benefit the most from adding a second.
Yes, but basement bathrooms often require an ejector pump ($500–$1,500) to lift waste up to the main sewer line if the drain is below the sewer connection. This adds cost but is a common and reliable solution.
