Seems like a good, well priced steam is hard to come by in Sydney, but I find them extremely beneficial and would like to know my options.
Price is definitely a factor. Prefer saunas, but a steam room is a close second, as long as they're nice and hot. I'm aware of these places already:
Ian Thorpe Aquatic Centre: Steam and sauna rooms that aren't nearly hot enough. Access to them and the pools is $15 or so for a casual visit.
C-Life Health Club, Belmore: Good steam room and pretty good value IF you also want to use the gym and fitness classes (Yoga/Boxing etc) at around $105 a month or less with long term memberships. I have a gym membership already and don't live that close though, alas.
Any others people know of?
I've seen people pour cold water on the temperature sensor in the steam room which results in lots more steam coming out.
