Hot tub

The hot tub is a type of object in The Sims Series. It provides fun, hygiene, social, and comfort to Sims who use it, as well as giving them a place to build relationships and even WooHoo. Extremely outgoing Sims may get in the tub naked. Don Lothario of Pleasantview was known for wooing his women into here, and then having woohoo with them.

In The Sims 2, pregnant Sims cannot get in a hot tub.

There are multiple hot tubs available in The Sims and its expansion packs, as well as multiple hot tubs available in The Sims 2. These tubs have different prices, different seating capacities (some seat 4, some seat only 2), and improve motives at different rates. Hot tubs can be bought from the plumbing section of the buy catalogue.

The Sims 2 has a hot tub (the Love Tub), which can be earned as an Aspiration reward.

If Seasons is installed, a hot tub will satisfy a PlantSim's need for water.

The Sims 3 base game contains no hot tubs. However, two different hot tubs were included in The Sims 3: Late Night (one more with using the buydebug cheat). Sims are able to WooHoo in hot tubs, Sims can cuddle & chat in the hot tub as well. You are able to change the colors of the lights in the Hot tubs Before the launch of The Sims 3: Late Night, people made hot tubs with cheats. Hot tubs have a slot where the portable stereo from the base game can be placed and used while soaking in the hot tub. If there is a Sim aged from baby through teen on a lot with a hot tub or pool, the skinny dipping interaction is disabled. The Sims 3: Outdoor Living Stuff also contains hot tubs, with the same functions as Late Night, except, if the player doesn't have The Sims 3: Late Night installed, the option to skinny dip won't be available. If a sim does skinny dip you can still hide their clothes if Ambitions is installed.

Glitches/Notes
The Hottub may have been included in the original game, as with World Adventures, Ambitions, and High End Loft expantions, a sim wanted me to buy him a Hot Tub.
