I spent my birthday at Island Spa & Sauna. It’s located in the same complex as Hmart and there were lots of parking. I booked a head massage in advance and it was truly worth it. The admission fee ($55) gave me full access to the bathhouses and saunas, so after the massage, I was still able to enjoy the other amenities. I do want to forewarn you that the bathhouses are fully nude (a little weird at first), however, male and female sections are separated. You can also just opt out entirely and move over to the sauna area. I definitely recommend visiting!
