Here are several Singapore hotels and resorts known for child-friendly pools with lifeguards or supervised waterplay. I’ve included a short note about the pool features and a source — please confirm times, age rules and lifeguard coverage with the hotel before booking (policies and staffing can change).

• Shangri‑La’s Rasa Sentosa Resort & Spa (Sentosa)

  • Why: Resort-style pools, separate kids’ splash zone, water slides and shallow children’s areas; reports and reviews note on‑duty lifeguards supervising slides and splash zones. (mumonthemove.com)

• Shangri‑La Hotel, Singapore (Orchard / city)

  • Why: Large family-friendly pool complex and children’s splash facilities; guest reviews mention lifeguards on duty at the kids’ pool/splash areas. (TripAdvisor.co.uk)

• Marina Bay Sands (city; rooftop infinity pool for hotel guests)

  • Why: Iconic rooftop infinity pool; multiple accounts and reviews indicate the pool is actively staffed by lifeguards and pool attendants (note: access restricted to registered guests and some rules apply). (Wanderlog.com)

• Resorts World Sentosa (Sentosa) — hotels + Adventure Cove Waterpark

  • Why: Resorts World includes family hotels (Festive/Hard Rock/Equarius/etc.) and Adventure Cove Waterpark (wave pool, lazy river, children’s areas) — waterpark and many resort pools are supervised by lifeguards. Great option if you want both hotel pools and a staffed waterpark. (en.wikipedia.org)

Practical tips

• Confirm lifeguard hours and whether lifeguards cover all pool areas (some hotels staff lifeguards only during peak hours or at specific attractions like slides/waterparks). Ask also about minimum lifeguard-to-guest ratios or age rules for unsupervised children.
• Ask whether any shallow/kiddie pools have barriers, non-slip surfaces, shade, and pool depth markings if you need child-safe design features.
• If having a lifeguard on duty is essential, request confirmation in writing (email) so you can see current policies for your travel dates.
• For extra safety bring properly fitting life vests for non-swimmers and supervise children even when lifeguards are present.

If you’d like, I can:

• Check lifeguard/pool supervision policies for specific hotels and your travel dates, or
• Suggest family‑friendly hotels in a particular neighbourhood (Marina Bay, Sentosa, Orchard) and include direct contact details for confirmation.
