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.

In The Sims 2, The Sims Stories, and The Sims 3, pregnant sims can not get into the hot tub.

The Sims
There are multiple hot tubs available in The Sims and its expansion packs. 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 catalog.

The Sims 2
Hot tubs in The Sims 2 fulfill Fun, Hygiene, and Social (if multiple Sims are in the hot tub). Sims can WooHoo and Try for Baby in a hot tub, although the success rate of Try for Baby is greatly decreased. Two hot tubs are available in the base game, and none are added with the expansions. The Sims 2 also has a hot tub (the Love Tub) which can be earned as an Aspiration reward that increases the success rate of romantic interactions while in the tub. All hot tubs in The Sims 2 and The Sims Stories seat four.

If Seasons is installed, a hot tub will satisfy a PlantSim's need for water. If FreeTime is installed, Sims can tinker with the hot tub.

The Sims 2 (console)

The Sims 3
Hot tubs in The Sims 3 are introduced in Late Night, and more variations of hot tubs are featured in subsequent expansion or stuff packs. The hot tub appears in certain number of packs, but the functionality is carried forward in the base game via patch. Therefore, it's possible to own a hot tub without the need of Late Night or other expansion packs, by using custom contents or store contents.

With the exception of one, usually all hot tub takes up 3x3 space. Only built-in floor hot tubs are available, unlike the previous games, and the hot tub will take up a section of space in the floor immediately below it to provide room for the tub and utilities. Sims are able to WooHoo in the hot tub. Sims can skinny dip in the hot tub as long as there's no teenagers or younger on the lot. Sims can also ask other Sims to skinny dip with them, and they often roll a romantic wish of it. The skinny dipping interaction requires Late Night, even if the functionality of hot tub is carried forward. Sims who relax in the hot tub can shorten the time period of "Fatigued" and "Sore" moodlets.

The Sims 3 Pets (console) has hot tubs which are from Late Night and feature skinny dipping. The order of which hot tub is the best has been swapped a bit; with the celebrity hot tub being second best and buyable, while the second best is best and has to be unlocked by solving the socialite club mystery.

The Sims 4
Hot tubs were reintroduced in The Sims 4: Perfect Patio Stuff as the Pringo's Heater Hot Tub and the Left of Center Hot Tub. Two different designs are available for each tub. Both tubs have a size of 3x3 tiles. Patch 92 added a hot tub to the base game, known as the Birthday Hot Tub.

For the first time in the series, children can enter hot tubs. Like previous games in the series, Sims inside the tub will chat with each other. Sims can also WooHoo and skinny dip inside the tub.

Upgrade list
Sims with the handiness skill can upgrade the hot tub to have an aromatherapy filter and a stereo.

Upgrading the hot tub with a high handiness skill unlocks several upgrade options, including the "Unbreakable" upgrade.
 * Aromatherapy Upgrade (Level 3 Handiness).
 * Stereo Upgrade (Level 5 Handiness).
 * Unbreakable Upgrade (Level 8 Handiness).

Glitches/Notes

 * A Hot tub can be obtained by unlocking it from TheSims3.com by posting a certain number of memories.
 * It is possible to skinny dip with a Teen or younger Sim on a lot by making those Sims leave the house, telling the adults to skinny dip and then having those Sims return. The Sims will continue to skinny dip but they cannot be commanded to skinny dip again.
 * If a Sim is equipped with an Audio Lite by LoFi Audio, the Sims will automatically place the boombox on one of the slots of the hot tub. This allows for music to be played while Sims go hot tubbing.
