Greater Philly housing stock and conditions
Philadelphia and the inner Delaware County boroughs are overwhelmingly pre-1930 rowhome and twin stock; Chester, Montgomery, and Bucks counties add large 1950s-1970s ranch and split-level inventory.
Narrow rowhome bathrooms (often under 40 sq ft) and load-bearing party walls make layout changes expensive, which pushes design toward keeping the existing plumbing wall.
- Space-first design dominates: 32x60 alcove replacements and corner showers rather than footprint changes
- Second-bathroom additions in rowhomes are a growing share of high-ticket projects
- Philadelphia L&I permitting timelines are a bigger schedule risk than material lead times

How King of Prussia compares with the national picture
The national direction is consistent everywhere: showers replace tubs in secondary baths, curbless entries move from specialty to standard, and ventilation gets specified deliberately instead of by default. What changes locally is how much of that work is triggered by failure versus choice, and how much the same scope costs.
