Soak & Sage - A Social Wellness Sauna Spa

Soak & Sage is a social wellness spa on Lake Washington Boulevard North in Renton, offering a shared thermal circuit alongside massage, skincare and medical spa services. The setting is designed for guests who enjoy restorative treatments in a communal atmosphere rather than a conventional day spa focused only on private appointments.

The main experience moves between warm thermal soaking and cold plunges, creating a contrast circuit intended to ease tension, refresh circulation and reawaken the senses. The sauna offering includes a Finnish cedar sauna and a temazcal, while a botanical steam experience adds humidity, warmth and an emphasis on breathing and skin renewal. A snow and cold plunge element provides another cooling stage for post-heat recovery.

The spa also incorporates an atmospheric cleansing and grounding element under the “Sage” pillar, complementing the heat and water experiences with a calmer sensory focus. Together, the facilities support a flexible visit built around alternating heat, water, cooling and rest. The experience suits solo wellness outings, paired visits and social occasions where conversation and relaxation are part of the appeal.

Beyond the thermal facilities, Soak & Sage offers customized massage treatments, including pregnancy massage, as well as facials tailored to concerns such as hydration, clarity and texture. Body treatments include a full-body scrub, hydrating wrap and mini facial combination. Med spa services extend into clinical skincare and cosmetic treatments, including fillers, microneedling and wrinkle-relaxing injectables. These options make the venue suitable for guests seeking either a short thermal reset or a broader appointment-based wellness day.

Group bookings are available for celebrations and larger gatherings, with options ranging from shared access alongside other spa guests to more private arrangements. The social format makes the venue a fit for birthday outings, wellness-centered get-togethers and small group occasions. Located in Renton, the spa provides a Seattle-area setting for thermal bathing, bodywork and skincare in one destination.
