Sauna

A sauna is a comfort-boosting object in The Sims 2: Bon Voyage and The Sims 4: Spa Day. It is also available after purchasing Sunlit Tides from The Sims 3 Store.

The Sims 2: Bon Voyage
The Sweat It Out Sauna is a sauna featured in The Sims 2: Bon Voyage. It can only be used by teenagers, adults, and elders. Sims will change into a towel wrapped around their waist or body before entering the sauna. While inside, they will sweat often, indicated by a wiping of their brow. Up to five Sims can use the same sauna at a time, with the lower bench filling up first. Once two Sims are seated on the lower bench, any additional Sims that use the sauna will climb up onto the upper bench. The lower bench always has a vacant spot, intended for use by Sims on the upper bench should they wish to enter or leave. Sims on the lower bench may frequently have to shuffle over in order to allow Sims behind them to exit. Sims will autonomously socialize in the sauna.

The sauna also serves as a WooHoo spot, and Sims can WooHoo or Try for Baby in a sauna. When done on a community lot, it will give the "Public WooHoo" memory.

If Seasons is installed, using a sauna will increase a Sim's internal temperature.

Saunas must be surrounded by a wall in order to exist. When purchased in buy mode, the sauna's walls will come pre-built, and will follow the sauna when moved. The walls can be repainted and reused, but cannot be removed without also removing the sauna. If the player removes one of the wall sections needed for the sauna, the sauna will be sold for its current value.

Saunas come in two colors — light and medium — and have panelings of the same color to match in build mode (titled "Heatonism Light Panel" and "Heatonism Medium Panel", respectively).

The Sims 4: Spa Day
The StoneZone Sauna and Artifical Fever Sauna are two Saunas that are introduced in The Sims 4: Spa Day Game Pack. They can be used by Children, Teenagers, Young Adults, Adults and Elders. Sims will change into a towel that will be wrapped around their waist or body before they use the sauna.

Saunas can also serve as a WooHoo Spot, Sims can Woohoo, Try for a Baby and Teens can Mess Around in the Sauna. Sims will get the Hot N' Steamy moodlet which lasts for 4 hours and gives the Sim the Flirty emotion.
