Cost to Bathroom Plumbing Rough-In in Miami, FL (2026)
If you’re budgeting a bathroom plumbing rough-in in Miami, most projects run $2,239-$7,166, 10% below the $4,500 national average. What moves that number most is usually one thing: Distance from Main Stack. On its own it can swing the cost by $1,000 - $5,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Position the new bathroom as close to the main drain stack as possible - every 10 feet of additional drain run adds $300-$600 in materials and labor
In the Southeast (where Miami sits): Lower labor costs; Florida markets run slightly above the regional average.
