WASHINGTON STATE — A dispute over who should be allowed inside a women's-only spa where clients are nude has moved from Lynnwood to the U.S. Supreme Court, where a petition was filed today asking the justices to weigh in.

At issue is transgender access, specifically transgender women at Olympus Spa, which offers traditional Korean body scrubs, open soaking pools and steam rooms in Lynnwood and Tacoma.

The case stems from a battle that began more than six years ago, when a transgender woman said she was denied access to the spa.

Olympus Spa had a longstanding policy that transgender women are welcome, but not if they are preoperative or have male anatomy. KOMO News spoke with clients outside the Lynnwood location Monday, and most said they had not heard about the case, though Liz Bloomberg said she was aware.

"I understand both perspectives," Bloomberg said. "I personally wouldn't be bothered by it (a preoperative transgender woman client), but I certainly respect why other women would be bothered by it. It's a sensitive topic."

"It depends on the company -- does the company take both sexes or not? If not, I may find it strange and not come back," said Alice, referring to a transgender woman with male anatomy inside the spa.

Kim Yuska, who came for a traditional full-body scrub she described as "a renewal" in preparation for her son's wedding on Friday, said she would not want to share the space with a transgender woman who has not had surgery.

"I probably wouldn't share it. I don't think I would participate," Yuska said, but when asked about a transgender woman who is post-surgery, "I don't think I would pay attention. I'm not staring at anybody. I'm going in there for myself."

Lead attorney John Bursch said the petition asks the Supreme Court to review the case on behalf of Olympus Spa and uphold the policy.
