Palatial, Dongbei-style bathhouse with seven floors of pools, hot-tubs, hot-stone rooms, oxygen rooms, pass-out-in-front-of-a-TV-watching-action-movies rooms, a small gym, a game room with a pool table and sometimes singers, a so-so hotpot restaurant, and one of the nicest rooftops in Puxi, where you can lay on pillows under the stars, order BBQ, and sip cocktails and cheap beers. Cheersum (Qianshen) is super clean and the vibe is low-key and relaxing, with warm lights and good service. Entry fee at this location only is 198rmb, including pajamas and slippers (other Cheersum locations are much more expensive). Compared to other popular bathhouses, Qianshen is more mature, more luxurious, and much less kid-friendly. Recommended. Good solo or with partners or friends. Bathing areas are segregated but there's lots of co-ed places to enjoy. The fact that you can stay overnight makes this a very cheap option for visiting Shanghai if you're ok sleeping in a common area, though they also have private rooms starting at around 400-500rmb.
