Billion Onsen and Spa sits on the first floor of Wisma Longrich on Jalan Yap Kwan Seng in Kampung Baru, a short walk from the KLCC area. The draw here is the onsen-style thermal pool setup paired with a sauna and steam room, giving the place a bathhouse feel rather than a straightforward treatment-room spa.
Beyond the soaking facilities, the menu extends into massage, facials, hair removal and other aesthetic treatments, so it functions as both a wellness stop and a day-spa in the broader sense. Couples treatments are offered, making it a reasonable pick for a pair looking to book a joint session rather than separate solo visits.
Access is a mix: walk-ins are welcome, but reservations are also required for at least some services, so calling ahead on 012-988 9057 or booking through the website is the safer route if you want a specific treatment or time slot. Staff communicate in English. The price tier sits in the moderate range for Kuala Lumpur spas, though the operator has not published fixed day-pass or treatment prices.
Posted hours only list Sunday as open around the clock, which looks like a gap in the published schedule rather than the full picture - worth confirming directly with the spa before planning a weekday visit.
