Club Sapphire

Club Sapphire is a private, membership-based lifestyle club at 14220 Interurban Ave S Suite A-110 in Tukwila, Washington, positioned centrally between Seattle, Bellevue and SeaTac Airport. Established for well over a decade, it caters to consensual, non-monogamous couples exploring the swinging lifestyle while also welcoming single women, a limited number of single men, and LGBTQ+ members. The club positions itself as a social space first rather than a straightforward sex club, with a membership base of adults 21 and up, ranging from their twenties to their seventies. The venue spans roughly 10,000 square feet, with a dance floor and resident DJ, social lounges, and a range of playrooms from larger group spaces to more private two-person rooms, including a dedicated voyeur room. A light buffet of appetizers runs throughout the evening alongside free soda, coffee, tea and water, and guests have access to a co-ed locker room, co-ed showers with four shower heads, and fresh towels; parking is free on site. The dress code favors dressed-up, sexy attire — designer jeans, dresses, lingerie or costumes for themed nights — while baggy sweats, dirty clothing, casual wear and baseball hats are turned away at the door. Parties run Wednesday and Thursday from 7pm to midnight and Friday and Saturday from 8pm to 2am. Entry requires both a current membership (from $30 for a one-week pass) and a separate per-event fee that varies by night and by couples/male/female category; all new members complete a brief, free orientation on party nights. Single men must secure a confirmed ticket in advance, cannot attend as walk-ins, and must complete a dedicated New Single Male Orientation before their first visit. House rules require verbal consent before any touching, ban illegal drugs, weapons and intoxicated entry, require condom use (condoms provided), and prohibit photography or cell phone use in social areas and playrooms.
