All children not yet potty-trained must wear either a Double Nappy (both a disposable or reusable swim nappy, and a Happy Nappy) to baby and toddler swimming lessons at Tonic Health Club, Castleknock Hotel. We also recommend a thermal layer (Baby Wrap, Warm In One, or Thermaswim) to keep children comfortable and warm for their full 30 minute session. Please note that lycra-type swimwear is designed for outdoor use only and is not designed to offer any thermal benefit.
Infant goggles are recommended for children attending our toddler and preschool levels, and should be worn with a swim hat to prevent any hair tangles or discomfort. Infant goggles are not required for our baby level swimming lessons.
All adults must wear a swim hat and swimwear. A pair of clear-lensed, clear framed googles are also recommended, especially for parents attending our baby levels.
Health & Safety
No buggies in the changing rooms, all buggies must be left in the Leisure Centre reception or other designated area. Car seats can be used in the Changing Rooms as required, please store them safely out of the way whilst your lesson is in progress. No food or snacks are to be consumed within the Changing Rooms, this is for both health and hygiene purposes.
