If last winter was the wettest weve had in a good long while, this one feels like the coldest. A bona fide snow day and a (nearly) white Christmas? Unheard of round these parts. If the scarves and space heaters just arent cutting it, lose them altogether and heat upwhile stripped down. Capitol Hills Hothouse Spa and Sauna is a ladies-only retreat, tucked beneath Pike Streets Wild Rose bar and outfitted with a eucalyptus-scented steam room, a warm wood-benched dry sauna, a hot tub, a cold plunge, a relaxation area, heated floors, filtered water (with fresh lime wedges!) and massage therapyall at affordable rates ($12 for one spa visit, massages extra). The no-boys-allowed coda also applies at Olympus Spa. With high-tech earth energy rooms (with names like Far-Infrared Heated Energy Room) and hydrotherapy pools, reap benefits such as increased blood circulation and expelling harmful toxins. Its all coed, all the time at the Russian-style Banya 5 spa, however. Another benefit, in addition to the wet and dry heat experiences, and pool plunges they promise will be a vivid circulatory experience? Venik Lounge, their newly-opened bar, offers the chance to re-toxify with a vast selection of house-infused vodkas. Hothouse, 1019 E.
