Dr. Drakken: First, you will be sealed inside a reinforced, titanium box. Next, you will be dropped into this bottomless chasm. Then, the chasm will be filled with water. Then, man-eating sharks and a giant squid will then be released into the water!
Shego: Huh? Wait — if the chasm is "bottomless," how can you fill it with water?
Dr. Drakken: IT'S VERY, VERY DEEP, ALRIGHT?!Slightly less perilous than a Lava Pit or Shark Pool but menacing none the less, the victim is Locked in a Room that is slowly filling with water. Could be accidental — like being sealed in a room with a busted water pipe — or an insane individual with a penchant for drama could have locked them there as cheap entertainment. Either way, the Big Damn Heroes better bash the glass wall or shut off the water before it's too late. Another variant involves the villain placing the hero inside some kind of non-buoyant container, a steel drum, vehicle, etc, and then tossing that into a large body of water. If the vehicle is a car, it's Trapped in a Sinking Car. Compare other death traps and Cement Shoes. Not to be confused with the band Drowning Pool.

Anime and Manga
- Lampshaded in Flame of Recca when Fuko and Domon are dropped into a vast empty pit. Domon jokingly says that there's no way it's going to fill up with water, and that the mystery button on the wall obviously will let them out. Of course, he pushes the button and it fills up with water.
- Pokémon: A nice inversion: when Ash is trapped in an airtight van, he uses Squirtle to flood it until the water pressure rips the doors off. How is Squirtle holding that much water? Don't ask.
- Pokemon Special has the "unmake-your-own" variant with a cable car.
- In One Piece, during the Alabasta arc, the saga's Big Bad, Sir Crocodile, left four of the six current Straw Hats (Luffy, Zoro, Nami, and Usopp), their Honorary True Companion Vivi, and their Inspector Javert Smoker to die in one of these; the Straw Hats and Smoker were locked in a cage and Vivi was being attacked by giant alligators while trying to save them, all while the room was starting to flood. Thankfully, they were saved by the last two Straw Hats, Sanji and Chopper.
- Saori and Gemini Kanon from Saint Seiya were locked in pits like these. Saori was in hers by Poseidon after rejecting his We Can Rule Together offer, Kanon was locked in his' by Saga after a huge disagreement. And it was through the pit that Kanon reached for Poseidon's realm, summoned him and then became Man Behind the Man. Nice job breaking it, Saga!
- A bounty hunter in Makai Senki Disgaea anime traps Laharl and his vassal Etna in a drowning pit. This is somewhat a variation of the point of a drowning pit, for Laharl and Etna are demons and can breathe and talk underwater. The danger was supposed to be from a sea creature in the water.
- Done by a murderer in one episode of Detective Conan. In this case, sitting the Asshole Victim in a very deep bathtub, then leaving the faucet slowly running till the water reaches a point where the victim ended up drowning due to being Bound and Gagged. And done in such a way that filling the tub will take hours. Aaaaaaaaargh!
- Another one was used in the past. More exactly, the jealous magician Motoyasu Tsukumo killed his own disciple Yashiro Kinoshita via transforming the water tank he was performing in into one of these, then leaving Yashiro to drown in public. Everyone thought it was an unfortunate accident since the trick was already very dangerous... but Yashiro's younger sister Mako didn't buy it. And 20 years later, she killed Tsukumo himself.
- In Goku Midnight Eye, the title character turns being in this situation into a Crowning Moment of Awesome when he is trapped in a hallway section that has been sealed off and is being filled with water. Using his cybernetic eye, he doesn't just open a door to either escape or drain the area, but he waits for a sufficient amount of water to fill in while closing and opening certain other doors on the floor, while the villains in the control room wonder what he is doing. Suddenly, Goku opens one door of his section and the water is rushed out towards the control room. The villains realize to their horror that he is directing the water and in effect turning the death trap into a weapon heading right for them!

The one who did this to her, a killer who found her snooping around for clues on the case she and Class Qu are working on, put the box on a raft, punctured a hole in it, and shoved it away from land in the middle of a lake. Inside the box, water slowly fills up with Sakurako inside and right about to drown, but the Class Q kids find her in time and manage to rescue her.

Another woman named Kichou, The Mistress to the cruel daimyo that had Yone imprisoned, is also put in there for helping the peasants behind the lord's back and because said Lord is already pissed off due to rumors that she has been sleeping with other men (she is in love with one of the protagonist, but they haven't had sex.)
- What's worse is that this did happen in Real Life.

- Done to Storm of the X-Men, with the added cruelty of the victim being severely claustrophobic. This would normally have been a stroke of twisted genius, but considering it was Arcade who did it, it was more likely just dumb luck.

It quickly becomes obvious that the only way out of this is to nick the wall separating the cavern from the underground lake, which they do, but the water comes in at such a high pressure that the way they came in from gets blocked, and the air gets harder to breathe as the water takes up more and more space.

It is also possible, by capturing and relocating dangerous aquatic creatures, to turn a Drowning Pit into a Shark Pool, possibly with Lethal Legendary Carp if the player so desires. However, actually getting that done is a challenge in its own while not substantially increasing the lethality of the trap, making it something of a Difficult But Awesome But Impractical option.
