Florida's climate, lifestyle, and real estate market make it the undisputed leader in outdoor kitchen installations nationwide.
FL's flat terrain makes drain slope difficult. Outdoor sinks cannot discharge to yard in most FL counties — violation of FL Dept of Health gray water rules. Must tie into home's drain or install a drywell (percolation test required in some counties).
Long runs from home may need a booster pump if outdoor appliances require >40 PSI. FL's flat terrain means minimal elevation-based pressure gain unlike other states.
Within 3 miles of salt water, all outdoor plumbing hardware must be stainless steel or marine-grade brass. Standard brass fittings corrode in 1–3 years in coastal FL environments.
Outdoor kitchens must have main shutoffs accessible for hurricane season. All outdoor gas connections must be properly secured and protected from wind-driven debris.

FL Building Code and county codes generally require outdoor showers to connect to the home's sanitary sewer/septic system — not to discharge directly to the yard.
Exception: Some FL counties allow outdoor shower discharge to a "vegetated filter strip" — check local county code. Coastal counties (Miami-Dade, Broward, Palm Beach) are the strictest and require full sanitary connection.
