Hidden among Duluth’s strip malls and congestion sits this neon-illuminated beacon of relaxation for adults and children alike. A mere $25 buys a full 24 hours of access to single-sex, clothing-optional locker rooms with steam rooms, saunas and showers. Once there, drop some extra bucks for an exfoliating body scrub or the (legal) green tea massage. Don the provided uniform and enter the co-ed area that boasts more than seven different steam rooms to purge your toxins. Grab a meal at the restaurant, drop your clothes off at the in-house laundromat and give the kids a few bucks for the arcade should you want to swim in the lap pool, relax in the charcoal dry sauna or get your tired soles kneaded in peace.
