Here are the top luxury hotels in Mumbai that combine large private suites with quality hotel pool facilities (note: true in‑suite/private plunge pools are very uncommon in the city—most properties offer guest‑exclusive hotel pools or poolside cabanas rather than pools inside a suite). Short picks with what makes each special:

• The Oberoi, Mumbai (Nariman Point) — renowned ocean‑view suites (Ocean View Suite, Executive suites, etc.) and a temperature‑controlled pool in a private courtyard; excellent service and classic location. (oberoihotels.com)
