A legendary institution in Seoul's wellness culture, Spa Lei is a massive, multi-floor, women-only upscale Jjimjilbang (traditional Korean bathhouse). Bypassing the hectic family-style public bath layouts, this female sanctuary is designed around traditional European and classic Asian thermal therapy. From outdoor open-air seawater baths and mineral mud chambers to intense, deep-cleansing traditional body scrubs (Seshin), it offers an authentic, deeply grounding local bathing ritual within a secure and highly comfortable setting.
