King SPA

King SPA is a Korean-style bathhouse and sauna complex just outside Washington, D.C., in Chantilly, Virginia. The layout follows the familiar jjimjilbang model: clothing-optional hot tubs, cold plunge pools, an outdoor bade pool and a Japanese hinoki bath are split into gender-specific areas, while a separate set of saunas, steam rooms, relaxation lounges and the dining area are mixed and open to everyone together.

The spa runs on a day-pass, walk-in basis, so no reservation is required to get in the door. Staff and signage are in English and Korean, and the facility also offers 18 treatments on the menu, including its signature Korean body scrub, plus couples treatment options for those who want a side-by-side session rather than solo time in the baths.

Access has one firm rule: the minimum age is 12, so this isn't a spot for young kids, though teens and adults of any age can use it together as a family outing. Gender-specific hours apply to the clothing-optional bathing areas, which is standard practice for this style of bathhouse and worth checking before you go if you're planning around a specific window.

Hours run long. Monday through Thursday and Sunday the facility is open 9 a.m. to 11 p.m., and on Friday and Saturday it stays open until midnight, making it a workable stop for an evening soak after work or a weekend visit that stretches into the night. Pricing sits in the moderate range for this category of spa.
