Just got back from Marmaris early hours of this morning. Last Tuesday I booked a Turkish Bath/Massage with Ossie & Eddie of Green Idyma Travel Agency (back of Club Atrium on road up to Club Julian). It cost me £5.00.
Someone came and picked me up from Xanthos Apart where I was staying and took me down to Pasa Beach Hotel on the beach front.
It was well worth the money - ten minutes in the sauna first (as if I needed to sit in there - it was in excess of 30 degrees C outside !!) followed by cold shower (certainly needed), then exfoliating scrub, rinse down, then all the warm foam of the turkish bath which included a massage, rinse down again, wrapped in towels to dry off for 15 minutes of so (there was also the option of a face mask at this point but it was at extra cost - 10 YTL I think), then the oil massage which lasted for about 30 minutes.
All in all a lovely relaxing start to my holiday.
