This minimalist, Korean-style communal bathhouse has two separate spa areas, one for men and one for women. Bathing suits are optional but you’ll likely find that most guests opt not to wear them. For an affordable price, you can get a four-hour pass to Imperial’s hot jacuzzi, dry and steam saunas, and cold plunge. Their wet spa body treatments focus on various purification scrubs, wraps, and oil massages, while their dry spa fixates on acupressure-focused massages. One great thing about Imperial is the spa stays open late (until 10 p.m., with the saunas shutting down at 9:45 p.m.), so you can head there after the office on days that warrant it.
