Well I really am going to sound like I work there now, but my husband and I have used the VIP suite at Amrita at Raffles the Plaza a few times. It has a steam shower, jacuzzi, and then we had treatments and lunch in the room too.
We've also used what I think they call the Presidential Suite at The Retreat at Changi Village Hotel. That was fabulous - there is a rooftop open air jacuzzi where you can sit buck naked and look out over Pulau Ubin. If you can't get that suite, the others on level 1 are quite nice too.
Both have websites.
Hedonist, me?
