Remodel Two Bathrooms at Once? Marin Homeowners Weigh the Tradeoffs

Design Build Specialists, a design-build remodeling firm with over 40 years of experience in Marin and Sonoma counties, is advising homeowners to consider remodeling multiple bathrooms simultaneously to avoid duplicated costs and disruptions. The firm, which has completed over 500 bathroom remodels, notes that a common regret is opening the same wall twice—finishing one bathroom only to return years later for another, paying setup costs again and reopening finished walls.

Much of the housing stock in the region was built between the 1940s and 1980s, with shared plumbing cores and wet walls. When one bathroom is remodeled, the supply lines, drains, and venting serving the other are often exposed and are typically the same age and condition. Coordinating projects can reduce overhead: one demolition phase, a single permit application, consolidated plumbing rough-in, tile from the same production lot, and one disruption window. However, the firm acknowledges that doing bathrooms separately can make sense if the home has only two bathrooms or if budget timing favors spreading costs. Marin bathroom remodels range from roughly $18,000 to $100,000 and up. Design Build Specialists approaches multi-bathroom remodel planning as a single design exercise with separate construction phases, ensuring selections are resolved together even when work is staged. The firm also offers a Design Build Clarity Plan as a standalone service to establish scope, cost, and sequencing before committing to construction. With over 700 water damage restoration projects under its belt, the firm is well-versed in handling common surprises like subfloor rot and corroded supply lines.
