B/SPOKE Studios East Boston (SAUNA)
125 Sumner St, Boston, MA
B/SPOKE's East Boston studio, a 3,320-square-foot boutique on Sumner Street a five-minute walk from Maverick station, is the one B/SPOKE location that sells standalone sauna time. The Boston fitness brand (five studios across downtown, Southie, Eastie, Wellesley and the Cape) added a RECOVERY line alongside its Ride, Strength, Yoga and Pilates classes, and in Eastie that means an infrared sauna you book like a class: a 30-minute SAUNA session, checked in through the app or at the front desk, with showers, a dry bar, programmable lockers, towel service and a purified-water station on the way out. There is no cold plunge here; B/SPOKE's contrast-therapy REVIVE sessions (infrared sauna plus cold plunge, 50 minutes) live at the South Boston studio. At $25 for 30 minutes, and $15 for a first visit, it is one of the cheapest booked infrared sessions in the city, and B/SPOKE's class memberships fold in monthly sauna sessions and recovery discounts of 15-50 percent depending on the tier. Buy a SAUNA credit (or a membership), reserve a slot on the schedule, and show up in clothes you are happy to sweat in with a water bottle; everything else is provided. The studio's doors follow its class schedule, roughly 5:30 a.m. to 8 p.m. Monday through Thursday, short morning and midday windows on Friday, and 9 a.m. to 2 p.m. on weekends, so sauna availability depends on what is on the schedule that day. Free street parking runs two hours outside.
