Bathroom Remodeling in Washington, DC
2026 planning guide · updated August 16, 2026
DC bathrooms are rowhouse bathrooms: stacked plumbing on 100-year-old cast iron, joists that have opinions, and the highest cost index in the region (we price DC at 1.08 in the estimator). Done right, they're also the highest-value square footage in the house.
What DC bathrooms run (2026)

| Primary bath, mid-range | $34,000 – $56,000 |

DC-specific notes
- Permits: DOB permits are required for plumbing and electrical scope; licensed-trade pulls are part of our price, not an extra.
- The cast-iron question: if your rowhouse still runs original stacks, budget mentally for discovering it — replacing a corroded section mid-project is the classic DC bathroom surprise our contingency exists for.
- Row-house venting: interior bathrooms need engineered ventilation paths; it's solvable, but it's a design item, not an afterthought.
