FAQ
1. Why is the Natatorium closing?
The Natatorium is undergoing a major renovation to improve the long term safety, reliability, and performance of the pool. This includes structural and system upgrades that cannot be completed while the pool is open.
2. How long will the pool be closed?
The renovation will begin on 26 January 2026 and is expected to last around 300 days.
The reopening date may change depending on construction progress and required safety inspections.
3. What work is being done during the renovation?
This project includes major structural improvements, including installation of a new metal liner and other essential upgrades to support the pool’s longevity.
An external contractor will manage all construction details.
4. Will the Natatorium building still be open?
Yes. Only the pool area will be closed.
All land-based classes (Jiu Jitsu, Karate, Yoga, Hula, Pound, Hip Hop, Animal Flow etc.) and front desk services will continue as normal inside the Natatorium.
5. Which programs are stopping during the closure?
Starting 26 January 2026, the following will pause:
Swim lessons (all levels)
Swim team
Lap swim
Open/recreational swim
Pool-based special events
Unit PT requiring pool use
These will resume once the renovation is complete and the pool passes safety inspections.
6. How will this affect swim lessons, and my existing lesson fees?
All swim lessons and swim team will pause at the Natatorium during the renovation. We plan to offer limited-capacity swim lessons at the Sakana Outdoor Pool during the summer months.
Swim lesson students that are signed up for January session will retain their priority status and will be notified before Sakana Outdoor Opening to sign up for summer swim lessons.
Front desk and Aquatics staff will assist customers individually.
7. What about the swim team?
The swim team will pause during the renovation. There is no indoor alternative available during this time.
8. Will lap swim be available anywhere?
Lap swim will not be available indoors during the closure.
We expect to offer lap swim hours at Sakana during the summer season, based on weather and water temperature.
9. When will the Sakana Outdoor Pool open?
Sakana is projected to open in May 2026 (weather permitting).
Programs expected during the summer include:
· Limited swim lessons
· Recreational swim
· Lap swim
· Seasonal community events
10. Will Sakana’s schedule be expanded because of the closure?
We plan to keep Sakana open as long as weather and safety standards allow. Outdoor pools must close when temperatures drop below recommended guidelines. This applies to if the pool opens in the spring, as well as if it stays open into the fall. As a general rule:
Outdoor pools operate safely when air temperatures are around 70°F (21°C) or higher,
And water temperatures remain above 78°F (25.5°C).
If temperatures fall below these levels, or wind chill makes conditions unsafe, the pool will close for the season to prevent cold related health risks, especially for children.
We will monitor weather daily and provide updates if early closure is needed.
11. Are there any nearby off base indoor pools we can use for lap swim while the Natatorium is closed?
Yes. There are several year round indoor heated pools in the local area that our community members can use for lap swim or general fitness. We are happy to provide these options and details upon request.
12. What happens to the lifeguards and aquatics staff?
Lifeguards may be reassigned to other FSS activities to support programs as needed.
Our goal is to retain trained staff so the pool can reopen smoothly when the renovation is complete.
13. Will unit PT still be available?
Pool-based PT will pause.
Units may coordinate with FSS Fitness & Sports for alternative PT options.
14. Will updates be provided during the renovation?
Yes. We will provide updates throughout the project through:
FSS social media
The FSS website
Facility signage
Front desk communication
15. Could the renovation take longer than planned?
Possibly. Construction timelines can be affected by weather, supply delays, or unforeseen issues.
We will communicate any changes as soon as they are confirmed.
16. Who can I contact if I have questions?
Please contact the Natatorium front desk or message us through official FSS communication channels.
Staff will help with updates and program information.
