Aqua Day Spa is a traditional Korean-style sauna on Convoy Street, gender-separated with steam sauna, dry sauna, hot jacuzzi, and cold tub, plus a men's sleep room and a women's Himalayan salt and red clay room. Entrance is $35 for a 3-hour visit, and bathing suits are strictly prohibited inside the spa or sauna. Any minor aged 13-17 must be accompanied by a same-gender parent or guardian with a signed consent form. The spa is open every day from 8:30 AM to 9:00 PM.

Its $35 drop-in sits below the San Diego median of $46, across the 7 studios here that publish one. It does not publish a plunge temperature (2 of the 19 San Diego studios we track do) — worth asking when you book. Not published access puts it with 11 of the 19 studios we track here; the rest run a different model.
