This top list starts with Rakudai Kishi no Cavalry. Stella lost the duel with Ikki, so she must be his slave for life. But Ikki is a good boy and doesn’t take advantage of this. Ikki was taking a bath when Stella surprised him by entering the bathroom wearing a bikini. She says that as she is a servant, she is supposed to wash his body. She gently washes Ikki’s body as he can’t take his eyes off her breasts. While washing his back, Stella asks Ikki if he likes girls’ breast. The answer is obvious because she knows where Ikki’s eyes were one moment ago. Then she holds him pushing her boobs against his back, but “casually” her top unties and falls on the floor. When she realizes it, she tries hard for Ikki not to look, and then this hot scene turns into a funny one.

Ranma ½ has a lot of bath scenes, but this is a whole chapter where Ranma goes to a public bath and he has to endure his master’s perversions and stop him from peeping in the girls’ bath. The English title for this episode is “Bathhouse Battle! We're in Some Hot Water Now”, so you can figure out how it’s going to end up. The water heater has broken down, so the group decides to go to a public bathhouse. Once there, Ranma notices Happosai carrying a bucket full of bath toys. When both of them are inside the pool, Happosai announces he is going to snorkel and goes underwater. Ranma quickly tugs his master closer with a ribbon on his wrist and pours water down the snorkel. After a while, Happosai tries to climb the wall with a pair of rubber gloves, but Ranma shoots him with a water pistol. As the time passes by, Happosai gets bored, so he finally sprays Ranma with cold water, turning him into a girl in front of the eyes of the other men. Furious, Ranma starts fighting with Happosai. Things really go out of control then.

Prison School got us used to great bath house scenes from the very beginning but this one is the best and not exactly for providing the viewers with fanservice. This entire scene is the product of a misunderstanding between Shingo, Gakuto and Kiyoshi in the bathroom. Shingo is confused about Kiyoshi sexual preference because of a conversation he has heard between Kiyoshi and Gakuto. When Shingo enters the shower room, he finds Gakuto kneeling in front of Kiyoshi so as to pick up the soap bar he dropped. Shingo can’t believe what he is seeing and hides behind the wall. Trying to convince himself that he is hallucinating, he enters the room again and this time finds Kiyoshi holding Gakuto from behind. When Kiyoshi and Gakuto notice the presence of Shingo, they feel embarrassed of the situation and invites Shingo to join them in the shower. Shingo misinterprets the whole situation and runs away. This is one of the most hilarious and awkward scenes ever. It isn’t common to find a bath scene involving men only, so this one is really enjoyable and I hope to see more like this.

The first part of this anime saga has almost begun in a bath, with Rito taking a bath when Lala appears naked on top of him. We can say it is a kind of gold mine bathing scenes. To Love-Ru Darkness pushed the limits a little bit further and sometimes it feels like you’re watching hentai. Nana and Momo are sharing a bath. Nana admits she is starting to develop feelings for Rito. Momo feels jealous and grabs Nana’s tail, the most sensitive part of a Devilukean. They end up getting into an erotic fight, stroking and licking each others tails, which lead them to an obvious result. Even though Nana and Momo having a bath together isn't new in the series, the way they ended up is a good example of ecchi yuri. This is probably the most explicit bathing scene in the anime.

This anime is from the same director as Revolutionary Girl Utena, which is a classic for yuri anime. Only by reading the title, we know what can be expected: “Yuri Kuma Arashi”, a storm of lesbian bears. Yes, the plot is a little surrealistic, but if you leave that on the side the anime is really good, one of the best of 2015, in fact. The show has a lot of great bathing scenes. The scenery usually is Kureha's pink bathtub. This scene is the best because it involves all three main characters. Ginko and Lulu are sharing the tub, and Lulu is washing Ginko’s hair. Then, Ginko starts to fantasize about Kureha joining her in the bath and washing her body as she gets closer and closer. The scene ends up with them transformed into bears, which turns the scene from sexy to cute.

Have you ever heard about a “foodgasm”? If you don’t, then you must watch this anime and you’ll discover a whole new world about the power of food. Although it’s an “ecchi” anime, bath scenes aren’t common in this show; actually, I think this is the only one. But with this scene they took all the credit. Soma was one of the first to finish the Dinner Assignment, so he heads up to the bathroom believing he is going to be the only one there. But he meets Gin Dojima stretching there, who mentions stretching in the bath is part of his daily routine. They feel a little uncomfortable but they start a conversation. Gin confesses he has planned to be done before the students come in, but mentions that the past year he was caught up by a student as well: Ikki senpai. Gin’s memories of Ikki and the scene he shares with Soma aren’t precisely manly. The scene jumps to the girls’ side of the bath and we get some fanservice action thanks to Tadokoro’s rubber duck floating between Sasaki’s boobs.

The whole group is getting settled at Rika's house. The girls are taking a bath, while the boys check the weapons and ammunition in the household. Of course, the interesting part is the one in the girls’ bath. While taking a bath, girls are impressed about the size of their sensei’s boobs. She says she is used to them, and immediately Rei grabs Shizuka’s breast and starts playing with them. Saya and Saeko are having a chat while taking a shower. Saya seems to be jealous about sensei’s big breast. Saeko changes the water temperature and shoots Saya with cold water. In revenge, Saya splashes a cube of cold water on Saeko’s back. But the best part is that during this scene, we can see Rei banging Shizuka from behind in a kind of doggy style way as Shizuka tries to get rid of her.

We are getting close to the top of the ranking. Even though the Araragi Bathroom has always offered us a good scenario, this scene has become the greatest bathing scene in the entire Monogatari series. Koyami has prepared a bath for Karen, but he decides to use it for himself. There he is caught by her sister Tsukihi, who was also planning on using the bath. After briefly arguing about who should use the bath first, they decide to bathe together. She mentions that Nadeko was released from the hospital. Koyomi is happy, but he realizes that without a god, the shrine will accumulate more dark energy, which will only cause more problems for the town. Tsukihi tells him that he shouldn't worry that much. Koyomi then finds out that he can’t see his reflection; he had turned into a real vampire. To prevent Tsukihi for watching in the mirror, Koyomi holds her head firmly. She thinks he wants to kiss her and seems to be willing to do it. At that very moment, Karen enters the bathroom and kicks both of them into the bathtub. This is one of the weirdest scenes I have recently seen. Imagine you are a vampire, having a bath with your sister and she is hot for you… WTF?

Valkyrie Drive: Mermaid has a great amount of bath scenes that shift between hot spring scenes and Charlotte's bathtub scenes. It also has a great amount of boobs, big boobs. But if I had to pick one scene it would be this one. This is actually a long scene of a hot spring at a beach. A few minutes before, it is revealed that Akira was actually a girl. Akira and Torino are having a relaxing bath in a hot spring. They talk for a while and fool around about how stressed they were. There is a shot where you can see the sunset between the breasts of one of them (pure poetry). When they are about to leave, Mamori and Mirei arrive. Just by looking at Akira naked, Mamori transforms into a sword. It seems to be love at first sight. Then the four girls share the bath, without knowing the real identity of Akira. The major question that rises up after this episode is: how did Akira manage to hide those boobs till now?

And the winner is… Studio Shaft with Nisekoi. The studio has done an outstanding job with adapting an average manga like Nisekoi into a really good anime series. The best bath scene of this ranking belongs to the 9th episode of this anime. Unlike the manga, the anime made this scene one of the best of the season with a lot of fanservice and humor at the same time. Claude changes the signs for the women’s and men’s baths, so Raku gets tricked into the wrong hot spring. Chitoge realizes Raku is there and goes mad, but then she understands it was all Claude’s fault. When she is trying to help him to escape, the other girls arrive and start talking about Kosaki's first love. Raku feels curious and tries to listen while hiding under the water. Kosaki runs away from the girls blocking Raku’s way out. When Chitoge realize this, he tries to move Kosaki away, but she stumbles and falls on top of Raku, who loses his towel as a result. Eventually, Raku manages to escape and reaches the men’s bath. This could be a classic scene between a girl and a guy in the onsen, but it has a big plus and it’s that the boy shouldn’t be there. At least that you are Ranma, being a boy in a girls’ bath is definitely not a good idea.
