How long does a bathroom renovation take in Washington?

A bathroom renovation in Washington, DC typically runs 3 to 11 months from your first design conversation through project completion, based on 391 completed MOSS bathroom renovation projects across the DMV region. The median project lands around 6 months. That full span covers three distinct phases: design and selections (where layouts, fixtures, and finishes are decided), permitting and approval, and then the actual on-site construction, which is often the shortest of the three phases.

Where your project falls within that range depends on several factors specific to Washington. Scope and structural complexity matter enormously, a straightforward refresh of an existing footprint moves far faster than a primary bath expansion that touches load-bearing walls or requires reconfiguring plumbing stacks. Permit review timelines through the District of Columbia's DCRA add real variability, as review queues and inspector scheduling in DC can extend the approval window beyond what you'd see in the Maryland or Virginia suburbs. Long-lead materials are another factor: custom tile, specialty plumbing fixtures, and steam units can carry 8 to 14 week lead times, and if those orders are placed late, they hold up construction regardless of how smoothly everything else is going. Washington also has a significant stock of rowhouses and older apartment buildings where hidden conditions, galvanized pipes, original cast-iron drains, or unexpected framing configurations, surface once walls open and require design or scope adjustments mid-project.

MOSS's design-buildmodel is built specifically to compress the timeline without cutting corners. Because our design and construction teams operate as a single unit, permit drawings are prepared and submitted as early as possible, often while you're still finalizing finish selections, so review time runs in parallel with decisions rather than after them. Long-lead materials are identified and ordered during the design phase, meaning they arrive at or before the construction start date rather than weeks into it. Having one accountable team from concept through closeout also eliminates the back-and-forth between separate designers and contractors that typically adds weeks to a project.
