The spa is the place for buying spa treatments, and also for getting a part-time job as either a Spa Receptionist or Spa Specialist. The main purpose of the spa is to relax Sims who are stressed, usually because of hard work at their jobs. It can grant a variety of moodlets. Spas will increase the mood of Sims by satisfying a variety of needs such as fun, hygiene, comfort and energy.
This is one of the properties Sims can partner with and own in The Sims 3.
Music from The Sims Buy/Build Mode can be heard while Sims visit the Spa.
