We'll call the shop for you ↓About this place
NotesThe hotel opened in 2012 as Mercure Ambassador Seoul Gangnam Sodowe and was rebranded to AC Hotel by Marriott in 2022. The bathhouse is on a basement floor and still uses the pre-rebrand layout, with wooden lockers and solid-timber benches. There are two pools, warm and cold, and no hot pool. On a visit in August 2026 the displayed temperatures were 40.5C and 21C, and the warm pool has a bubble jet. The dry sauna showed 80.7C and has a full glass window looking back toward the baths. Washing is set up two ways: standing shower booths divided by frosted glass, and facing them, the seated wash stations familiar from Korean bathhouses. The changing room has scales, hair dryers and a fridge of bottled water. A sign on the entrance door states, in Korean and English, that mobile phones may not be used.
Practical notes
To use the sauna you swap keys at the L-floor lobby: hand in your room key, say you are going to the sauna, and you get a sauna locker key plus a card key for entry, swapping back on the way out. A cabinet beside the basin in the changing room holds towels and mesh shower towels, so there is nothing to bring. Washing is set up two ways — two standing booths divided by glass, and two seated stations facing them — with bath baskets in two sizes. There are also two wooden ladles of the kind used at Japanese ryokan. A sign at the entrance prohibits phone use, so leave yours in the locker. There is no jjimjilbang floor where you sit around in a uniform; it is baths and a sauna only, so plan a short visit. Check with the hotel about whether non-guests may use the facility and at what rate.
