Tub-to-shower conversions in Washington, DC, Maryland, and Northern Virginia
Removing an alcove tub and adding a walk-in or curbless shower is one of the most common bathroom remodels in the DMV. This guide explains the key decisions, cost drivers, and what to expect.
Key decisions
Shower type: A curbed shower is simpler and less expensive. A curbless shower requires floor recessing and a linear drain, which adds structural and plumbing work — particularly complex in concrete-slab condos common in Arlington and Bethesda.
Drain relocation: If the new shower drain location differs from the tub drain, plumbing relocation adds labor and material cost. Keeping the drain in the same location reduces complexity.
Tile and waterproofing: Custom tiled showers require a waterproofing system (membrane, slope, and proper drainage). Never reduce waterproofing to save cost. Fairfax County and Montgomery County inspectors are particularly attentive to this detail.
Glass enclosure: Frameless enclosures cost more than framed or semi-frameless options. In narrow DC rowhouse bathrooms, sliding or pivot doors may be necessary due to space constraints.
Shower features: Benches, niches, handheld showers, and rain showerheads each add to the scope. Consider which features you will actually use.
Aging-in-place considerations: If accessibility is a goal, a curbless entry with grab-bar blocking and a handheld shower is worth the additional investment.
Cost factors specific to the DMV
- Labor rates in DC proper are typically higher than suburban Maryland or Prince William County
- Condo buildings in Bethesda, Arlington, and DC may require additional labor for material transport and debris removal
- Historic district properties may have restrictions on visible exterior changes if windows are modified
- Older homes in DC, Alexandria, and Takoma Park may have galvanized plumbing that requires replacement
Permit considerations
Tub-to-shower conversions usually involve plumbing changes, which often require a plumbing permit. If the shower is curbless and the floor is modified, a building permit may also apply. Your contractor confirms with your local jurisdiction.
How to plan
Use the Renovessa planner to capture your bathroom dimensions, select tub-to-shower conversion as the objective, and choose your finish tier. The planner produces a localized planning range and a contractor-ready brief.
