Frequently Asked Questions

How much does a bathroom addition cost in Evanston?
Adding a bathroom in Evanston costs $5,800–$63,200. A half bath (toilet + sink, ~35 sqft) runs $5,800–$3,800. A full bath (60–80 sqft) costs $3,800–$20,800. A master bath with walk-in shower, double vanity, and premium tile can reach $63,200.
Is adding a bathroom worth it in Evanston?
Adding a bathroom typically returns 50–60% of the cost at resale in Evanston. Homes with only 1 bathroom gain the most value from a second bath. Half bath additions near living areas have the best ROI — typically $10,000–$25,000 added to home value.
How long does bathroom addition take in Evanston?
A half bath addition takes 2–4 weeks. A full bath addition takes 3–6 weeks. A master bath with custom tile work can take 6–10 weeks. In Evanston, allow 2–4 weeks extra for permit approval. Plan for the space to be unusable during construction.
Can I add a bathroom without breaking through walls in Evanston?
If you're converting existing space (large closet, unused room corner) and plumbing lines are accessible, you may minimize wall opening. However, new bathrooms need supply lines, drain lines, and venting — which almost always requires some wall or floor access. A licensed plumber in Evanston can advise on the least invasive approach.
