Olympic-length pool open to non-residents. Clean facilities, affordable day passes. Good for serious swimmers looking for lap swimming in central Bangkok.
RSU Tower Pool and Gym fills a specific and important niche in Bangkok's fitness landscape: affordable, quality lap swimming in a central location. While many premium gyms offer pools, they come with expensive memberships. And while Bangkok has public pools, their condition and accessibility vary widely. RSU Tower provides a clean, well-maintained, Olympic-length pool with affordable day passes and monthly options, making it the best dedicated swimming option in the Sukhumvit area for both residents and visitors.
The main attraction is a 50-meter Olympic-length outdoor pool that is well-maintained and properly chlorinated. Lane lines are set up for lap swimming, and the pool is deep enough for proper technique work. The water quality is consistently good — clean, clear, and at a comfortable temperature year-round given Bangkok's climate. A smaller pool is also available for less intense swimming and cooling off. The pool deck has lounging areas for rest between sets.
For serious swimmers, the 50-meter length is significant. Most gym pools in Bangkok are 25 meters, and while adequate for basic fitness swimming, the longer pool allows for proper endurance training, flip turns at appropriate intervals, and a swimming experience that more closely matches competition conditions.
The gym component is basic but functional, with cardio machines and a modest selection of weights and resistance equipment. This is not a destination gym — think of it as a supplement to the pool rather than a standalone fitness facility. The equipment is adequate for a warm-up or light training session before or after swimming but does not compete with dedicated gyms like Fitness First or Base Bangkok.
Day passes run 200-400 baht depending on the time and whether you use just the pool or pool plus gym. Monthly swimming passes are available and offer significant savings for regular swimmers — typically 2,000-3,000 baht per month for unlimited pool access. These rates are a fraction of what you would pay for a Virgin Active or Fitness First Platinum membership just for pool access. Annual packages bring the monthly cost down further.
Early morning between 6:00 and 8:00 AM offers the emptiest lanes and coolest outdoor temperatures. Midday is quiet on weekdays but can be hot given the outdoor exposure. Late afternoon from 4:00 to 6:00 PM sees more swimmers arriving after work. Weekend mornings attract families, so lap swimmers may prefer weekday visits. The pool operates on set hours, so confirm the current schedule before visiting.
RSU Tower is located on Sukhumvit Road, accessible from BTS stations along the Sukhumvit line. The exact location is convenient for residents of the central Sukhumvit area. A short BTS ride or taxi from most Sukhumvit hotels makes it easily accessible for visitors as well.
Changing rooms with showers and lockers are provided. Towels may or may not be included depending on the pass type — bring your own to be safe. A small food and drink area is available. Swim caps are required (you can purchase one on-site if needed). Goggles are available for purchase but bringing your own is recommended.
Bring your passport for registration on your first visit. The staff speaks basic English. Swim caps are mandatory — this is strictly enforced. If you plan to swim regularly, the monthly pass is much better value than repeated day passes. The outdoor pool means sunscreen is important, especially for midday swims. Rain does not typically close the pool — swimming in a warm Bangkok rain shower is actually a pleasant experience.
For dedicated swimmers, RSU Tower offers the best value proposition in central Bangkok. Virgin Active has excellent 25-meter pools but requires a full gym membership at 4,000-7,000 baht monthly. Fitness First Platinum branches have pools but similarly require full membership. Public pools operated by the Bangkok Metropolitan Authority are cheaper but often crowded and inconsistently maintained. RSU Tower hits the sweet spot of quality, price, and accessibility for anyone whose primary fitness activity is swimming.
