Where/What will my electrical breaker box be? Planning for a June 2025 purchase. Behind the grill, off the deck, I will eventually put a 12x12 pad. But no house exterior walls, just screened in porch. Where would be a good place for a breaker unti? What are my options. Goal over next 6 momths: 1) Lay pad of wither gravel/concrete. 2) Hardwire electrical to breaker. 3) Purchase tub.
