-->"Seven strangers, picked to live in a mansion..." -- ''TheRealWorld: New Orleans''

A RealityShow staple, typified by an extravagant mansion complete with a fully stocked bar, and a ConfessionCam. The reality TV show mansion usually has no television and no single rooms, encouraging maximum interaction among contestants and limited contact with the outside world.

Typically, these high-end homes are rented from private citizens for the duration of the show. Hence, the reason that some Reality TV Show Mansions appear very similar... they may in fact be the same house. When they're not the same, many a viewer has wondered what happens to the house and everything in it after the season is over.

Nonetheless, the luxury of the reality show mansion may arguably be viewed as one of the attractions for signing up to be a reality TV show star.

[[folder: Live-Action TV ]]

* Almost every 'elimination-style' competitive reality show takes place in a mansion:
** ''Series/AmericasNextTopModel'': Usually a lavish, loft-style apartment complete with runway for practice, with every inch of wall covered in pictures of host Creator/TyraBanks.
** ''Series/AmericanIdol'': The first 2 seasons showcased the lavish house in which the singers lived, but this was dropped starting with the third season.
** ''Series/TheApprentice'': The Apprentices usually live in lavish penthouses in Manhattan, with the exception of Season 6, where the losing team was forced to live in "Tent City".
*** The UK incarnation saw the teams living in a succession of high-class London houses, although in Season 5 it was downgraded to a far more modest, but still pretty nice apartment.
** ''Making The Band''
** ''LastComicStanding''
** ''Series/TheJoeSchmoShow''
** Even ''TheNextFoodNetworkStar'' used this trope, until Season 7 got overloaded with so many {{Soap Opera}}-ish elements (in large part thanks to the ImNotHereToMakeFriends-quoting AlphaBitch Penny) that the following season featured a retool that has so far resulted in the show reverting back to showing the strictly food and presentation-related aspects of the drama and relocated the contestants to hotel rather than a mansion, apparently making Season 7 a GenreKiller as far as this trope and many or the related tropes are concerned.
** ''BigBrother''. Some editions of ''BigBrother'' had a system with two connected houses: a luxury house and a poor house. The contestants were initially all put in one of them (the other one being hidden), but later divided into two (sometimes competing) groups with fluctuating memberships, one for each of the houses.
** ''Series/EstateOfPanic'' is a subversion; the show ''does'' take place in a mansion, and it ''is'' properly extravagant in its design, but the contestants don't live there - the mansion ''is'' the challenge of the show, a freaky fun house built as the playground for the elimination-based competition.
** While not the setting, the competitors live in such a mansion in ''Series/{{Face Off}}''. We only see a few minutes of it at the beginning of each episode, usually focusing on their reaction to the previous episode.
*** Their makeup lab may be a closer example - it has just about everything an effects artist could want, generally producing a "kid in a candy store" effect on the competitors. It's also quite open, allowing the competitors to see what the others are doing.
* All of the competitive dating shows, including:
** ''TheBachelor'' and ''TheBachelorette''
** ''BeautyAndTheGeek''
** ''JoeMillionaire''
** ''Series/FlavorOfLove''
*** All of its spin-offs use a redecorated version of ''the same mansion''.
** ''Series/ILoveNewYork''
** ''Series/RockOfLove''
*** The most recent season averted the trope by having the contestants living on buses that followed Bret's tour bus around the country. Lavishly appointed buses yes, but spacious? [[{{HilarityEnsues}} No.]] The reason? A lawsuit was filed by the owner of the mansion after the second season, seeking compensation for all the damage the contestants did to the house.
** ''Paradise Hotel''
** ''{{Excused}}''
** ''Frank The Entertainer In A Basement Affair'' subverts this. The contestants expect a RealityTVShowMansion, but end up all living in '''Frank's parent's house'''.
** ''Series/IWannaMarryHarry'' has Englefield House, which is a real English country home.
* ''TheRealWorld'': Though the first season of the show featured fairly modest accommodations, starting with the third season the cast members have lived in extravagantly decorated mansions.
** The luxury suite in the Palms hotel from the [[VivaLasVegas Las Vegas season]] is available to rent.
* ''The Surreal Life''
* ''Wrestling/WWEToughEnough's'' first season hosted the contestants in a hundred-year-old rural Connecticut mansion, a fairly short distance away from the [=WWE=] headquarters and other facilities. The mansion itself was owned by a [=WWE=] producer and was rented by the company for use in the show. During the first episode after the selection process, host Wrestling/AlSnow laid down the law, warning the contestants that they were guests in this man's home and that if there were any damage to the building because of them, ''there would be hell to pay''.
* ''TheUltimateFighter'': The fighters from both teams live in one large house. Occasionally, a fighter cites interpersonal issues as part of his motivation for beating someone in the octagon.
* Many {{Music Video}}s take place in something like this, especially those for GlamRap.

!!Fictional examples:

[[folder: Fan Works ]]

* Prior to ''VideoGame/SuperSmashBros. Brawl'''s Subspace Emissary mode giving the series an actual story for the first time, many ''Smash'' FanFiction took place in "the Smash Mansion", where all the Smash Bros. characters live together while they're not fighting.
* ''{{Fandemonium}}''. Nearly the entire plot takes place in Fandemonium Mansion. Occasionally, they go outside. That's about it.

[[/folder]]

[[folder: Literature ]]

* ''House Arrest'', in the Creator/BenElton novel ''Dead Famous''
* ''It's a Madhouse'', in the Creator/KimNewman short story "Going to Series".
* Subverted ''horribly'' in Creator/ChuckPalahniuk's ''Literature/{{Haunted 2005}}''. All the writers are put up in a well-stocked private complex (a former theater), but each of them has the idea to sabotage their own stuff with the intent that their subsequent tell-all book deals would be more compelling. In short order, the place has become an unlivable nightmare.
* ''Literature/TheHungerGames'': Tributes live in the lap of luxury for the few days leading up to the actual Games.

[[folder: Live-Action TV ]]

* A sort of fictional non-fictional example in ''DeadSet''. As it turns out, the BigBrother House is in fact one of the safest places to be during a ZombieApocalypse due to it's heightened security. [[spoiler: [[TooDumbToLive Too bad one of the contestants was stupid enough to try to escape]], [[DownerEnding exposing the house to invasion]].]]

[[folder: Web Comics ]]

* ''AnsemRetort'' has characters from ''KingdomHearts'' living together.

[[/folder]]

[[folder: Web Original ]]

* WebVideo/SexHouse appears to be set in one of these. [[spoiler:Until the contestants realize there literally IS nothing consumable in the house but booze and moldy bread. And the house is increbily [[NoOSHACompliance poorly constructed]] and have no garbage disposal, making it a severe health hazard in several ways. [[SealedRoomInTheMiddleOfNowhere And they're locked in.]]]]

* ''DrawnTogether'': The mansion is one of the consistent features of this otherwise continuity-void cartoon.
