Plan rooftop swimming in St Louis for June to August, since average highs fall to 6.9°C in December and 4.7°C in January. Each of the 3 hotels we list has its pool on the roof. None publishes its access rules, so we can't point you to a day pass or call any of them guests-only.
Our first pick is Four Seasons St. Louis: a heated pool with private cabanas and a splash pad, plus a 12,000 sq ft spa in the same hotel. For a smaller place, Hyatt Centric Downtown has 142 rooms and puts the pool, a bar and a sun terrace together on the roof.

Hotels you might expect here, and why they're not
These hotels come up in searches for rooftop pools in St Louis, but none has a pool on the roof.
Hilton St. Louis at the Ballpark. Only one third-party source (trip101) covers the roof, and it says there is no rooftop swimming pool, only a roof bar and restaurant. The Google Maps listing gives no pool information. This matches the not-rooftop definition for a rooftop bar without a pool.
St. Louis Union Station Hotel, Curio Collection by Hilton. No source describes a swimming pool at this hotel. The Trip101 ranking lists it under rooftop pools but gives only price and parking. The Google Maps listing gives only name and address. Status is "not-rooftop" because no pool is stated.
Drury Plaza Hotel St. Louis At The Arch. The hotel's own site lists an "Indoor Pool & Two Whirlpools", and trip101 describes it as an "Indoor pool (not rooftop)". The eighth-floor terrace is mentioned for views only, with no pool.
HoteLumière at the Arch - A Caesars Rewards Destination. Only third-party source describing the pool (trip101 ranking page) says it is an indoor swimming pool with hot tub, not on a roof. The Google Maps listing gives only the address. No source places a pool on the roof or a top-floor terrace.
Marriott St. Louis Grand. No source places a pool on the roof. A 2016 guest review and Orbitz say there is no pool, while a booking page lists an indoor pool. The Le Méridien Clayton Facebook snippet is about a different hotel and was ignored.
21c Museum Hotel St Louis. The hotel's own spa page describes the pool as an "historic, indoor 4-lane lap pool", so it is not on the roof or a top-floor terrace.
Moonrise Hotel. The hotel's pages describe an 8th-floor rooftop bar and Twilight Room lounge, but no source mentions a swimming pool.
Live! by Loews - St. Louis, Missouri. The hotel's own FAQ states it has no pool. Its outdoor rooftop terrace, The Bullock, is a bar and event space with no pool mentioned.
