Yes, some public toilets in Double Bay offer shower facilities, which is handy for active lifestyles in this coastal area. The Public Toilets at 542 New South Head Rd (in Blackburn Gardens) include changing and shower facilities, praised for being ideal after sports, beach activities, or a sweaty walk around the suburb. These are moderately clean and functional, ensuring a comfortable rinse-off. Visitors appreciate the privacy of separate male and female toilets alongside these amenities. However, the Public Toilets at Steyne Park (2 William St) do not mention showers, focusing instead on standard clean facilities in a park setting. If showers are essential, head to the Blackburn Gardens location for this added convenience. Both are free to use and accessible, but review the post's list to confirm details and opening times, as they align with park hours in this NSW spot.
