Not published by The Plunge San Diego: intro offer, sauna type, towels.
About prices: $35 full-day pass includes the sauna, obstacle course, locker rooms and lap lanes; a cheaper timed session pass is also sold ($18 for 1 hour, $20 for 2 hours). Two membership tiers are listed at $75 and $100/month but the site's benefits table did not make clear from the page text which tier includes sauna access; worth a call to confirm.
