Entry No. 1 — the San Diego file — filed under: bathhouse
Yu Spa
A Korean jjimjilbang where the walls of one sauna are lined floor-to-ceiling in Himalayan salt, another is coated in red clay imported from Korea, and a third — the 'Ice Room' — is lined with exposed freezer evaporator coils you sit inside on purpose.
The story
Tucked into a Convoy Street strip mall amidst Kearny Mesa’s endless corridor of hot pot spots and boba shops, Yu Spa operates as a traditional Korean jjimjilbang hiding in plain sight. You check in at the front desk, hand over your footwear, and trade your street clothes for a standard-issue cotton lounge uniform before stepping into the main unisex thermal circuit.
The room design here skips soft lighting for raw materiality. One heating chamber is constructed floor-to-ceiling from Himalayan pink salt blocks. Another is coated in heavy red clay imported directly from Korea, throwing off a deep, baking heat. The sharpest contrast is the Ice Room: rather than relying on chilled air ducts, you sit inside a freezer chamber wrapped in exposed, frost-covered evaporator coils designed to shock your system after a heavy sweat.
What it's like
After changing into the provided spa clothes, you are free to cycle between the shared salt, clay, and ice rooms at your own pace. The experience branches when you head to the gender-separated bathhouse sections—here, clothing is prohibited and you'll find hot and cold plunge tubs, steam rooms, dry saunas, and scrub stations. If you opt for an add-on like a traditional body scrub, an attendant will scrub down every inch of skin on a waterproof table. Check current operating hours before heading over, as schedule changes happen.
The move: Get the ~$45-55 general admission, change into the required spa uniform, and rotate together through the salt sauna, clay sauna, and ice room before finishing in the shared hot/cold tubs; split off for gender-separated body scrubs or a yoni steam if you want the full ritual.

Good to know
What should I wear while visiting Yu Spa?
General admission provides a mandatory cotton lounge uniform (t-shirt and shorts) for the shared co-ed salt, clay, and ice rooms. Inside the gender-separated wet areas (tubs, steam room, scrub tables), no clothing is permitted.
Do I need an appointment just to use the saunas and tubs?
No, general admission grants day access to all the jjimjilbang thermal rooms and gender-separated bathhouse tubs. Specific services like body scrubs, massages, or yoni steams require separate booking.
How does the room rotation work?
Most visitors spend 15–20 minutes absorbing heat in the red clay or Himalayan salt chambers, transition directly into the Ice Room to sit beside the frozen coils, and then head to the gender-segregated wet rooms for hot and cold plunge tub rotations.
