Spa bath

A spa bath is an activity in The Sims: Superstar, The Sims 3: Store, and The Sims 4: Spa Day.

The Sims: Superstar
Spa baths are done in the Ponce de Leon Tub, which can be placed on both residential and community lots. Baths are free on residential lots, while a §100 fee is charged when used on a community lot. Sims can choose from a Mud Bath, a Milk Bath, or a Sulfur Bath. Sims will change into their swimsuits before entering, although very outgoing Sims will get in naked.

Whilst in the tub, Sims will flex and relax as their comfort motives increase. If there are other Sims using spa objects in the same room, they will start a conversation. When a Sim is finished, they will scrub themselves before exiting and draining the tub.

The Sims 4: Spa Day
Unlike The Sims: Superstar, spa baths in The Sims 4: Spa Day are not separate objects, but rather interactions added to all normal bathtubs. Sims have the option of taking baths with various soaks or mud, which will alter their emotions.

While relaxing in a bath, Sims will wear a face mask with cucumber slices over their eyes. They will be naked when bathing in soaks, but they wear swimsuits instead when bathing in mud. It's recommended to put spa baths in separate rooms to avoid having Sims become embarrassed from seeing each other in the nude.
