Gunite Pool vs Fiberglass Pool
Gunite is fully custom and lasts 50+ years at $80k–$200k; fiberglass shells install in 3–5 weeks at $55k–$120k but are size-limited (≤16 ft wide) and don't fit narrow hillside lots.
Plunge Pool / Cocktail Pool vs Pool with Spa
A plunge pool fits LA's small lots at $55k–$85k and skips most decking; adding an integrated spa pushes the project to $90k–$170k but extends use into winter.
