Already a gym member, looking for pay-as-you-go pool, sauna, hot tub In Dublin

So I’v always been a member of the Carlisle Ben Dunne gym. It used to be perfect for me cos after my weights session, I could go for a quick swim then chill out in the hot tub and sauna area. I’m still a member now and I enjoy the weights/cardio facilities and the cheap prices, but they’ve removed the pool area so I need to find somewhere else I can go once a week or so just to use the pool/hot-tub/sauna.

I know Swan Leisure pool in Rathmines has PAYG options, but the hours are inconvenient. For instance today (Monday) the pool is only open for public use from 10am-2pm.

I was thinking of quitting Carlisle to join Gym Plus in Rathfarnham but their pool has awkward closing times too, and you need to book in several days in advance.

UCD pool/spa looks great but pretty sure there’s no PAYG option.

I really like using saunas/hot tubs occasionally just to chill out and get away from screens, traffic, etc.

I know COVID has probably made it more difficult, but it seems odd that there’s not many places offering this. In any other countries I lived in there was lots of publicly accessible gyms with pool areas where you could just pay a fiver and pop in for a few hours.

Any suggestions? I live in Rathgar area so preferably cycling distance from there, but have a car too.
