->''"If you're gonna do shit in the bath, how about some fucking spelling?!"''
-->-- '''Geoff Ramsey''', ''[[Creator/AchievementHunter The Off Topic Podcast]]''

This is when two characters [[FuroScene take a bath together]] and usually converse. This causes them to really get to know each other better or become better friends. Usually either really significant moments of the plot are discussed or one character's past is revealed in a Bathtub Bonding scene.

Most of the time they are HeterosexualLifePartners; rarely are they ever PlatonicLifePartners, though this can be used if the PlatonicLifePartners in question have enough UnresolvedSexualTension between them to make them popular targets for shipping and the writer wants to do a scene where said UnresolvedSexualTension comes to a head.

At least two characters have to share a bathtub (be it at home, at a hotel, during a PublicBathhouseScene, or during a HotSpringsEpisode) in order to qualify for this trope.


[[folder: Advertising]]
* The iconic bathtubs in [[SideEffectsInclude commercials for Cialis]], a drug that helps with [[TheLoinsSleepTonight erectile dysfunction]]. The couples are not in the same tub, but they're in two old-fashioned bathtubs next to each other on the beach, holding hands.

[[folder:Anime & Manga]]
Relatively common in anime due to the Japanese concept of "skinship".
* ''Manga/AkagamiNoShirayukihime'':
** After getting caught in the rain while traveling Mitsuhide stays as a guard while Zen and Obi take a bath in the large bathroom at an inn. Shirayuki and Kiki also bathe together at the inn and while both pairs get a bit of time to just chat between the two of them [[TheGadfly Obi]] uses the time to mostly tease and fluster Zen, joking about peaking in on the girls and saying that now he'll be forced to picture Zen naked if Zen ever again says something about wanting his aides (including Obi) to be happy in life again now that he's done so while they were bathing.
** In Lyrias Shirayuki and Izuru are invited to a public bathhouse by Yuzuri to celebrate the success of the Olin Maris experiments, when Suzu hears about this he decides to bring the guys to the bathhouse as well in order to relax a bit and Obi, Ryuu and Kirito come along with him and the guys end up talking about their relationship prospects.
* Hilariously subverted in Webcomic/AxisPowersHetalia, where Italy and Japan bathe together in a hot spring... but what ''could'' have been this trope [[MomentKiller is ruined]] when Italy implies [[TeenyWeenie that Japan is a lightweight in his pants]].
* In the original manga, OVA, and remake manga version of ''Anime/BirdyTheMighty'', one episode has Tsutomu's father head to the bath to join him in some "father-son naked bonding time", as he puts it. Tsutomu's mother naturally has a WTF reaction. However, Tsutomu's father ended up [[AccidentalPervert seeing a naked Birdy instead]].
* It is done in ''Butt-Attack Punisher Girl Gautaman R'' but to an uncomfortable extent.
* Song Goku and Son Gohan do this while training in the Room of Spirit and Time in ''Anime/DragonBallZ''.
* Lucy and Kana share a bath in ''Manga/FairyTail''. Lampshaded when Kana asks if Lucy usually fits two to a bath, and Lucy counters by asking if Kana [[DropInCharacter usually breaks into other people's houses]], since characters breaking into Lucy's house is something of a running gag.
* In the eighth episode of ''LightNovel/TheFamiliarOfZero'', it is done with [[FishOutOfWater Saito]] and Siesta, who are opposite genders. Saito had [[ItMakesSenseInContext just built a hot tub]], and Siesta has a crush on him. He was planning on being there alone, and is punished by his master (and local {{Tsundere}}) Louise when he shows interest in other women. He has feelings for Siesta, but is in a HaremSeries, so it's awkward for him.
* [[BathingBeauty Rushuna]] and Mikan bathtub bond in the ninth episode of ''Anime/{{Grenadier}}''.
* In ''Manga/HidamariSketch'', Miyako practically ''forces'' her way into Yuno's bath, on account of her having no running water in her own apartment (as [[CloudCuckooLander she keeps forgetting to pay the water bills]]. Poor, shy Yuno doesn't know what hits her. Still, it pays off, since both girls are the best of friends ever after.
* In ''LightNovel/HighSchoolDxD'', Asia (a European) tries to invoke this when Issei accidentally walks in on her in the bath, saying that she's heard of the Japanese practice of communal bathing and would be okay doing that with him to strengthen their relationship. Issei tells her she's misunderstood the idea.[[note]]This is an excuse on Issei's part - he'd love to, but can't trust himself not to hit for a home run. Asia doesn't quite grasp this, [[ChivalrousPervert so he won't tempt himself]].[[/note]] The trope is expanded upon in the anime, where the girls often have their bonding conversations in hot springs and the like, and Rias and Souna conduct important devil business meeting while naked in the latter's steam room.
* ''Manga/HimechanNoRibon'': Hime-chan and Pokota, [[LivingToys her magical talking stuff toy]], do this in the seventh episode when talking about how to deal with Himeko's current problem.
* The first ending of ''Manga/ICantUnderstandWhatMyHusbandIsSaying'' has [[HappilyMarried Kaoru and Hajime]] relaxing in the bath together (ending with Kaoru doing a BathKick). Later episodes would add them washing each other's backs.
* Kagome and Sango have done this in episode 29 of ''Manga/InuYasha'' and in the [[Anime/InuYashaTheMovieTheCastleBeyondTheLookingGlass second movie]]. Neither instance was actually in a bathtub, but rather in a hot spring.
* Akane and Mikoto in ''LightNovel/{{Kampfer}}.'' [[LesYay Bonus points]] for Mikoto's blatantly sensual poses and Akane's [[LuminescentBlush shyness]] about looking at her.
* In ''Anime/ALittleSnowFairySugar'', Sugar and Saga often share a bath to discuss the day's events, with pint-sized Sugar sitting on Saga's knees to keep from drowning. Saga also uses the bath to bond with Kanon.
* ''Franchise/LyricalNanoha'' has three of these scenes:
** Attempted by Fate in the [[AudioAdaptation first Sound Stage]] of ''Anime/MagicalGirlLyricalNanohaAs'', though Amy interrupted her before she could gather up her courage to ask Nanoha to go to the bath tub with her.
** On the other hand, her adopted daughter Caro was a lot less nervous about this in [[AudioAdaptation the first Sound Stage]] of ''[[Anime/MagicalGirlLyricalNanohaStrikers StrikerS]]''. She just jumped right into Erio's side of the Hot Springs (kids under 11 are allowed to go anywhere they want) [[PuppyLove to do some serious bonding with him]], much to Erio's horror and embarassment.
** Fate also likes bathing with her children, and in one of the one-shots, gets quite disappointed when Vivio expresses a desire to take a bath by herself in order to appear grown-up.
* This happens a lot in ''Manga/MahouSenseiNegima'', although there usually aren't any romantic undertones due to the fact that Negi is ten, and ObliviousToLove... and then there came Eva. Being TheVamp that she is, she ''wanted'' it to be sexual but failed miserably because, as stated above, Negi hasn't reached puberty yet. (Technically, [[NotGrowingUpSucks neither has Eva]].)
* Episode 23 of ''Anime/MaiOtome'' has Mai sharing a hot tub in the middle of a thick forest with Natsuki, it being the first time they've met face-to-face since they both left school. Natsuki spent the last several years since then wondering why Mai suddenly disappeared, and asks for her help in her fight against [[BigBad Nagi]] and the Schwarz army.
* Nadia from ''Anime/NadiaTheSecretOfBlueWater'' bathtub bonds with Electra in episode 20. She also bonds with Grandis in a bubble bath in episode 33.
* Pictured above: In the 28th episode of ''Manga/{{Nana}}'', Hachi jumps into Nana's bath, which at first becomes uncomfortable for Nana, but then not so much.
* In episode 24 of ''Anime/NeonGenesisEvangelion'', [[spoiler: the newly appointed 5th child Kaworu Nagisa]] gets into the bath with Shinji. What follows is the most important step in their relationship development.
* ''[[LightNovel/{{Bakemonogatari}} Nisemonogatari]]'' dedicated a whole episode to a scene regarding Koyomi and Shinobu having a discussion in the bathtub together.
* The 10th episode of ''Manga/OmamoriHimari'' does this.
* Nanako and Mariko share one of these scenes in ''Manga/OniisamaE'', complete with [[ACupAngst Nanako]] being embarrassed as she compares her body with [[HourGlassHottie Mariko]]'s.
* Miina and Karen do this in pretty much every episode of ''Anime/PleaseTwins''.
* PlayedForLaughs in ''Manga/SchoolRumble'' when Eri tries to do this with Motoko, but ends up with Harima. Harima ends having to pretend to be Motoko so he doesn't get caught.
* In the ''Manga/SensualPhrase'' manga, [[HugeGuyTinyGirl Aine and Sakuya]] ''try'' to enact the trope -- [[AvertedTrope but they fail]] since Sakuya is much taller than the average Japanese dude and thus they simply don't fit in the deep yet also ''very'' short ''furo'' tub they tried to use.
* Male example: A chapter of the ''Manga/SgtFrog'' manga had Fuyuki and Keroro doing this. Then [[LoadsAndLoadsOfCharacters members of the supporting cast]] show up and try to join in... meanwhile, Natsumi is feeling left out but refuses to admit it.
* Uruka and Saki bond in a bubble bath in episodes 5 and 6 of ''Anime/SteelAngelKurumi2''.
* There is a bathtub bonding scene in ''Anime/StreetFighterAlphaGenerations''. The local GenkiGirl Sakura Kasugano bathes with Fuuka, the cute granddaughter of an OldMaster that she and Ryu are staying with.
* In the first episode of ''Manga/{{Zetman}}'', after taking the homeless ten-year-old Jin into her home, Akemi climbs into the bath with him to comfort him in his grief over the death of his adopted grandfather.

[[folder:Fan Works]]
* [[http://www.fanfiction.net/s/6731465/3/Nanoha_As_Divergence In this fic]], [[CrackPairing Vita and Yuuno]] did that while waiting for others to come, and Vita learned about [[TrainingFromHell the origin of his scars]] and it's seems that they start to [[TrueCompanions trust each other after that]] (even having NotADate five days later). [[OneOfUs Also mentioned with name]] in the omake section.
* A throwaway gag in ''[[FanFicRecs/TheLegendOfZelda The Weekly Hyrule News]]'' is Link and Dark showering together; it's mentioned more in the DeadFic sequel. Nothing significant happens except to highlight Dark's {{Keet}}-like personality, and that they're comfortable around each other.
* [[http://community.livejournal.com/withnail_i_fic/5165.html This]] short ''Film/WithnailAndI'' fic. However, they don't really bond.

* Done a couple times in the movie ''Film/HeavenlyCreatures''.
* Used in the movie ''Film/{{Tart}}''.

* In the film ''Film/ShanghaiNoon'', Roy and Chon spend some time bonding in the bath. Technically most of this happens while they are in separate tubs, but the scene is shot to give the impression of shared space, and then they end up in the same tub until they're interrupted.
* Narrowly averted in ''Film/TheTalentedMrRipley'' when Tom Ripley and Dickie Greenleaf play chess together while Dickie is in the bath. Dickie expresses his [[{{Wangst}} dissatisfaction]] with being an only child, while Tom's lingering stares again alert the viewer to Tom's [[HoYay growing fascination]] with Dickie.
--> '''Tom:''' I'm cold, can I get in?\\
'''Dickie:''' ... No.\\
'''Tom:''' ''(embarrassed)'' I didn't mean with you in it.
* Harry and Lloyd did it in ''Film/DumbAndDumber'', and it was a heart-shaped bathtub to boot!
* That's how Michael and Hanna in [[TheMovie the film version]] of ''Literature/TheReader'' kick off their sexual journey.
* In ''Film/BigFish'' old Edward shares a bathtub with his wife Sandra. Both of them are still clothed, though (yes, while it's full of water). But it's still very sweet.
* This happens in ''Film/{{Buffalo 66}}'' between the main characters, a man and a young woman where they bond silently. In this situation, the girl does have a thing for the man, he doesn't make a move and eventually tells her to get out.

* In ''Literature/ASongOfIceAndFire'', Jaime and Brienne share a bath during which he explains why he killed the mad king Aerys to her, his reason being something that he hasn't really told others before.
** The bathtub in question is really more like a hot tub -- big enough for five or six people. It still counts, though.
* The plot of the ''Literature/{{Maisy}}'' picture book ''Maisy Takes a Bath'', later adapted for the animated series, was that Maisy Mouse wanted to take a bath, but her friend Tallulah the chicken kept knocking on her door, wanting her to come out and play. At the end of the story, Tallulah hopped in the bath with Maisy and they had fun together.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'': Genevieve with Faith in Season 8.
* ''Series/GameOfThrones'': While at first it might look like a simple BathtubScene in a series notorious for its {{Fanservice}}, the scene between Jaime and Brienne in "Kissed By Fire" quickly becomes a pivotal moment in their CharacterDevelopment.
* Happens once or twice in ''Series/KyleXY'' between Kyle and other characters (usually Amanda or Jessie). Notably there isn't ever water in the tub. [[AnOddPlaceToSleep He sleeps in it]].
* Several episodes of ''Series/XenaWarriorPrincess'' have Xena and Gabrielle sharing a bath. [[SlashFic Slash fans]] rejoiced.

* When Eric and Hyde of Series/That70sShow first met they were kids and to spite him not liking Eric that much Kitty got them to have a bath together which as teenagers Eric seem's less embarrassed about than Hyde.
* ''Series/MillionYenWomen'': Nanaka at some point imposes this upon Shin by undressing and coming into a tub in which he was already bathing. [[spoiler:It turns out to be so she can tell Shin what she figured out about the invitation sender without any of their housemates hearing her.]]

[[folder:Video Games]]
* ''VideoGame/SamAndMaxFreelancePolice'': Sam and Max apparently took baths together when they were kids, according to photos in their office.
* In ''VideoGame/HyperdimensionNeptuniaVictory'', Neptune, Plutia and Noire wash each other off after the climax of the first chapter. The scene is actually the punchline to a ''very'' elaborate ExactWords joke.[[labelnote:Explanation]]During the preceding event, Iris Heart (Plutia's BastardGirlfriend SuperMode) would only cough up some PlotCoupons to the other two if they offered her something in return. Neptune ends up offering her body, and Noire grudgingly swears to do any one thing Iris Heart asks. Fortunately for the game's rating, Plutia had transformed back by the time she collects on that, ''washing'' Neptune's body and making Noire rub her down in turn.[[/labelnote]]
* Shared baths are the ''level-up mechanic'' for Reyvetails in ''VideoGame/ArTonelicoIIMelodyOfMetafalica'', and include conversations between the girls.
* Can be invoked throughout the ''VideoGame/{{Suikoden}}'' series with the different bath houses, and works as a clever way to develop characters that otherwise wouldn't get a lot of spotlight shined on them.
* In ''[[VideoGame/MusouStars Warriors All-Stars]]'', there's a hot springs in the game's central hub. Encountering other characters in the springs will raise your Regard Levels with them, and unlock specific event scenes as well.

Including Judau, whom she has declared her "big brother". The only one who actually agrees to the idea is her clone, Ple-2.

[[folder:Visual Novels]]
* In ''VisualNovel/{{Kanon}}'', Yuuichi can try to get in the bath with Makoto. Twice.
** In the anime, suggesting this is Yuuichi's immediate recovery upon [[AccidentalPervert accidentally walking in on Makoto naked]]. She doesn't take it well.

[[folder:Web Comics]]
* Linda convinces Russell to try this in ''Webcomic/{{Transmission}}''. However, it doesn't exactly work. [[http://transmission.thecomicseries.com/comics/300 At least, as far as Russell is concerned...]]

[[folder:Web Animation]]
* In the [[WebAnimation/HomestarRunner Strong Bad email]] [[http://www.homestarrunner.com/sbemail175.html "concert"]], Strong Bad and Strong Sad talk for a while about a band they both like in various locales, one of which is sharing a mud[[note]]or so they thought, until the Poopsmith popped up from the bottom of the bath[[/note]] bath together.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'': The season six episode "Grampa vs. Sexual Inadequacy" has Homer and Marge trying to pump some new blood into their tired love life by having a candlelit bath for two. This doesn't work as the tub is too small, Homer is too fat, and it ends with the two of them stuck in the tub in complete darkness, yelling for the kids to help them out.
* ''WesternAnimation/FamilyGuy''
** Similarly, on the movie "Stewie Griffin: The Untold Story", Peter and Lois get in the tub together. Peter has to move his big, fat stomach out of the way so that she can get into the tub. He holds his stomach out of the way until she's comfortable, and then he lets go of his stomach and it smacks Lois in the face and her head rebounds off the faucet. The kids interrupt the bath with their inane arguing, so Peter and Lois decide to teach the kids how to date so they can get some alone time. The scene ends with Lois trying to lean in to kiss Peter, only to slip out of the tub, and Peter to notice that she's bleeding from a possible head injury.
** Subverted with Stewie and Meg. Stewie farts in the tub. They laugh. Meg farts in the tub. They laugh. Meg accidentally queefs. Stewie screams and hightails it out of the tub.
* ''WesternAnimation/AmericanDad'' had a particularly {{Squick}}y one on the episode, "Oedipal Panties". After Roger tells Francine that there are no signs of disturbing togetherness between Stan and his mother, Francine asks Roger to go in the bathroom and get her some aspirin, which Roger accepts since he's going through a "white month" (read: he's exercising and cleansing his body of all the drugs, alcohol, and junk food he regularly consumes) and needs an excuse to work his leg muscles. When Roger opens the door, he sees Stan and his mother in the bath, with Stan singing a variant of "What Do You Do With a Drunken Sailor?" and washing his mom. A commercial break later, Roger can be seen traumatized and holding a cup of (what can only assumed to be) booze.
* The animated sketch "Die Herren im Bad" ("The Gentlemen in the Bathtub") by the [[GermanHumor German humorist]] Creator/{{Loriot}} shows two [[ExactlyWhatItSaysOnTheTin gentlemen in the bathtub]] of a hotel room. Their conversation, while relatively well-mannered, is more bickering rather than bonding, though.

* In Finland, getting invited to sauna together with the host is a sign of really deep friendship.
* In Japan, it's common for older and younger family members to bathe together and it's seen as a bonding experience.
* 24-hour saunas are common in Korea and used for bonding, business meetings, or even a place to sleep.
