The little private rooms with the baths have a dressing room, a shower between the dressing room and the bath, and then the room with the bath, which is considerably larger than an ordinary bathtub so you can stretch out your arms without touching the walls.
As of when I was there, they charged $35.00 (Canadian, of course) for an hour session, with discounts for purchasing several sessions in advance.
They also provide other `holistic health services', such as massage therapy, acupuncture, and homeopathy. They sell books, New Age music, and aromatherapy and homeopathic remedies and rent videotapes.
Their flyer says they have a home page at http://www.ottawa.net/~aqua/, but I wasn't able to connect to that server when I tried.
Their phone number is 613/241-7001 and their address is
Aquasphère 24 Clarence St Ottawa, ON K1N 5P3 CANADA
