The cost to add a bathroom in Peoria ranges from $11,780 to $49,100, with most homeowners paying around $24,550. Your actual cost depends on several factors specific to your home and the Phoenix-Mesa 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.

Flooring Type

Tile floors in bathrooms cost more to install than vinyl or laminate but offer better water resistance and durability in wet areas.

🔧
Fixture Quality

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.

How long does bathroom addition take in Peoria?

Most bathroom addition projects in Peoria take 14–45 days to complete. The timeline depends on project scope, contractor availability in the Phoenix-Mesa metro area, and seasonal demand. Scheduling during Peoria's off-peak season (typically late fall through early spring) can reduce wait times and may lower costs.

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.

Can I add a bathroom to my basement?
