No, the public bathrooms in Wahroonga are not open 24 hours. All listed facilities operate from 6 am to 10 pm daily, providing reliable extended hours but closing overnight. Public Toilets Wahroonga Park on Illoura Ave earns praise for these consistent timings, suiting most daily needs in the area. Similarly, Public Toilets Wahroonga Village Car Park at 9 Coonanbarra Rd is appreciated for late openings that helped visitors in urgent situations, though it shuts at 10 pm. Public Toilets Claude Cameron Grove on Westbrook Ave also follows this schedule, with some users wishing for later access, but the 6 am to 10 pm window ensures well-maintained operations. In Wahroonga, part of the Hornsby Shire, these hours align with standard public amenity management to balance accessibility and security. For 24-hour options, emergency services or service stations might be better, but always check the list for the most convenient daytime spots.
