Bathroom Remodeling in Washington, DC

What bathroom remodeling services are available in Washington, DC?

Participating Washington, DC pros handle rowhouse bathroom remodels, second and third bathroom additions, English basement bathrooms, walk-in showers, tub-to-shower conversions, condo bathrooms and accessibility upgrades. The most common DC project is adding a bathroom where there was none. The most common complication is a shared drain stack that runs through more than one unit.

Full bathroom remodels. The rowhouse hall bath, rebuilt: open the plaster, replace the galvanized supply and often the cast-iron stack shared with the floor below, correct the venting that was never right, and rework the layout in a room that may be only five feet wide. Participating pros who work Capitol Hill, Petworth and Bloomingdale know the Wardman and porch-front floor plans and where the stack usually runs.

Second and third bathrooms. The most common DC addition is a bathroom where there was none: a powder room under the stairs, a primary bath carved from a rear bedroom, or a full bath for the basement unit. Each is a plumbing-path question first.

English basement bathrooms. Below-grade, usually below the sewer line, so an ejector pump is routine. If the unit is or will be a rental, the Department of Buildings and the Department of Licensing and Consumer Protection have requirements the estimate should reflect.

Walk-in showers and tub-to-shower conversions. Popular in the 1950s and 1960s brick colonials and ramblers of Chevy Chase DC, American University Park and Hillcrest, and for anyone aging in place in a house with stairs. Benches, hand-held sprays and grab-bar blocking as standard.

Condo bathrooms. Navy Yard, NoMa, Logan Circle and the converted buildings of Dupont and Adams Morgan. Building rules about wet-over-dry stacking, work hours, insurance certificates and plumbing shutoffs shape what can be done and when.

Shower-to-tub conversions, bath liners, fixture replacement, floor tiling, accessibility. For a seated bathing option see walk-in tubs.

Why are Washington, DC bathrooms different?

DC bathrooms are rowhouse bathrooms: narrow, stacked over the kitchen, sharing a stack with the floor below, and often sitting in a rear addition with cold walls on three sides. Humid summers, a combined sewer in the older city, pre-1978 materials, and building rules in condos and basement rentals all shape what a remodel involves.

Stacked plumbing in party-wall houses. Rowhouse bathrooms share stacks and sometimes vents with the kitchen below and, in converted houses, with the unit downstairs. Replacing a stack means coordinating with the whole house, and the estimate should say whether that is in scope.

Narrow rooms and rear additions. Many DC bathrooms sit in a rear addition built after the house, with its own foundation, its own settling and a cold exterior wall on three sides. Insulation, air sealing and plumbing placement matter more there than anywhere else in the house.

Humid summers. DC's summers are long and wet, and a rowhouse bathroom with a single small window and no fan is a mildew problem. Permitted work adds a properly sized exhaust fan vented outdoors, which in a middle rowhouse often means a run to the roof.

Old materials. Galvanized supply, cast iron, lath and plaster, and in houses from before 1978, lead paint on trim that falls under the EPA's renovation rules when disturbed. Knob-and-tube wiring still turns up in some Capitol Hill and Georgetown homes.

Combined sewers and backups. Much of the older city runs on a combined storm and sanitary sewer. Basement bathrooms should budget for a backwater valve.

Permits and historic districts. The DC Department of Buildings issues permits. Interior bathroom work in a historic district such as Capitol Hill, Georgetown or Mount Pleasant usually does not need historic review, since the review covers what is visible from the street, but a new roof vent or rear window can. Condos add the building's own approval on top.

How much does a bathroom remodel cost in Washington, DC, and how long does it take?

A mid-range full remodel of a Washington, DC rowhouse bathroom typically runs $18,000 to $38,000, including supply and stack work, and a tub-to-shower conversion $8,000 to $18,000. An English basement bathroom usually lands between $20,000 and $40,000 once the ejector pump, backwater valve and any rental-unit requirements are in. Conversions take two to five working days and rowhouse full remodels three to five weeks.

• Tub-to-shower conversion: $8,000 to $18,000, two to five working days.
• Rowhouse full remodel with stack work: $18,000 to $38,000, three to five weeks.
• English basement bathroom: $20,000 to $40,000, longer when the unit must meet rental requirements.
• Condo bathrooms: add for the building's insurance certificate, elevator reservations and restricted hours; the calendar stretches more than the price.
• Permit: DC Department of Buildings, pulled by the pro. Interior work in a historic district normally needs no historic review.

How does the bathroom remodel process work in Washington, DC?

The process has four steps: a consultation that traces the stack and vent and notes condo or basement-unit requirements, written estimates compared side by side, construction, and a final walkthrough. DC permits add two to six weeks before work starts, and condo approvals can add more, so allow eight to twelve weeks of calendar time for a full remodel.

1. Consultation. Submit the form or call. Participating pros that serve your DC zip code visit, measure, trace the stack and vent, and note condo or basement-unit requirements.
2. Design and estimates. Written estimates with scope, materials, what happens to the stack, ventilation path, and schedule. Compare them side by side.
3. Construction. Conversions take two to five working days. Rowhouse full remodels run three to five weeks when the stack is involved. Condo projects follow the building's work-hour rules, which can stretch the calendar.
4. Final walkthrough. Fixtures run, fan tested, permit inspections closed, then final payment.
