What's Included in Rough-In
🔩 Drain Lines (ABS/PVC)
FL plumbers use ABS or Schedule 40 PVC drain lines. Minimum 3" for toilets, 1.5"–2" for sinks and tubs. Code requires a minimum slope of ¼" per linear foot toward the main stack. PVC is preferred in FL for its excellent corrosion resistance in humid, mineral-rich water conditions. All joints must be solvent-welded and air-tested before inspection. Cleanout access required per FL Building Code.
💧 Supply Lines — PEX-A Recommended
PEX-A tubing is strongly recommended in FL. More flexible than copper, handles occasional freeze events in North FL, and resists corrosion from FL's hard, mineral-heavy water. Standard sizing: ½" to fixtures, ¾" main trunk lines. Color-coded per code: red = hot, blue = cold. Manifold systems allow per-fixture isolation without cutting walls — ideal for hurricane prep and leak management.
🌬️ Vent Stack Connections
FL Building Code requires all fixtures to be properly vented to prevent trap siphoning and sewer gas infiltration. Air Admittance Valves (AAVs) are permitted in FL for certain applications where roof penetration is impractical. Primary vents must extend through the roof with proper flashing — critical in FL's high-rainfall climate. Typical 2"–3" PVC vent stack connection at the main soil stack.
🔐 Per-Fixture Shut-Off Valves
Florida Building Code requires individual quarter-turn ball valves at every fixture (toilet, sink, shower supply lines). Ball valves are preferred over gate valves — they seal completely and don't corrode internally over time. Essential for hurricane prep: you can isolate individual fixtures without shutting off the whole house. Standard installations include angle stops at toilet and vanity, inline shutoffs for shower supplies.
♨️ Pressure Balancing — FL FBC 2017+
Florida Building Code (2017+) mandates pressure-balancing or thermostatic mixing valves in all showers and tub/shower combinations. Must maintain set temperature within ±3°F when demand fluctuates. Prevents dangerous scalding when a toilet flushes mid-shower. Adds $150–$400 to shower valve line item. Thermostatic valves cost more but allow precise preset temperature controls — highly recommended for master baths.

Fixture Entry Level Mid-Range High-End
Toilet$350–$550$600–$900$1,200–$2,500
Vanity + Sink$450–$750$800–$1,500$2,000–$6,000
Tub$600–$1,000$1,200–$2,500$3,500–$8,000
Shower (tile)$2,500–$4,500$5,000–$9,000$12,000–$25,000
Faucet Set$200–$400$500–$900$1,200–$3,000
FL-Specific Considerations
Hard Water Damage — FL water is mineral-heavy. Chrome fixtures pit and discolor within 2–3 years. Brushed nickel, oil-rubbed bronze, or PVD-coated brass finishes hold up far longer. Consider adding a water softener rough-in loop while walls are open during any renovation.
Ventilation Required by Code — FL Building Code R303.3 mandates mechanical ventilation in all bathrooms lacking operable windows. Minimum 50 CFM fan; upgrade to 80–110 CFM for master baths. Mold risk is extremely high in FL without proper airflow. ENERGY STAR fans are strongly preferred in humid climates.
Concrete Slab Penetrations — Most FL homes are slab-on-grade construction. Any new bathroom addition or drain line rerouting requires saw-cutting the concrete slab ($800–$2,000 add-on). Budget for concrete patch and skim coat before any tile or flooring installation.
Hurricane & Flood Prep — Install accessible main water shutoffs. Check your FEMA flood zone designation — AE/VE zones affect permit requirements, elevation requirements for water heaters, and homeowner's insurance costs. Factor into planning before breaking ground.

FL requires permits for new rough-in and full gut-replumb. Typical permit cost: $150–$600. Add 10–15 working days for permit approval and inspection scheduling.
