View from Rama 2 road:
Open 14-24, entry 170 Baht (under 21 year olds 99 Baht).
1st floor reception, Jacuzzi (accessible from 2nd floor)
2nd floor locker room
3rd floor sauna, steam room, gym
4th rest room, TV room
5th rest room, rooftop garden, smoking corner
Everything new and clean. Private rooms have electronic candle (a LED shines on a plastic foil that has a shape of a flame and is moved by an electromagnet? to make it move like a flame). Towels so-so (normal towel cut in half?).
The other customer is not my type, but when he starts touching me in locker room, I let him rim and suck me as I have nothing else to do. Lie on my back and read on my mobile phone while he is working on me and I think "I could* take a video of him sucking my dick", then I notice that we are in good view of security camera and abort. Upon leaving, I can't see video of the security camera at receptionist's workplace, where is it recorded or displayed?
*possibility, not intent
Continue to Phoenix (bus 68 does not drive past Phoenix, get off at The Mall Tha Phra and walk).
Verdict: nice place and location ok, needs more customers. Others report the same: http://sawatdeenetwork.com/v4/showthread.php?17982-waterboys-onsen
and private communication with a friend who went multiple times.
