On the right is a Checkpoint Flag and a Crazy Cap. Mario must be wearing the Swim Goggles and either the Swimwear or Boxer Shorts for the Lochlady to let him in. On the left is a locked door guarded by a Lochlady which leads inside the display window, where Mario can throw Cappy onto the dress stand to spawn a Power Moon. This floor features the Water Plaza Display Window where the Lochlady Dress is kept, though the dress is missing until the main story's completion due to Bowser stealing it. The second floor has entrances on both the left and right side of the dome. A water elevator on the left can be used to travel between the first floor and second floor. There are multiple alcoves in the back, one of which leads to a secret room where a Lochlady will give Mario a Power Moon for keeping the hidden room a secret. There is a deep pool in the center that leads to a domed camp site where Captain Toad will give Mario a Power Moon. The first floor can be accessed through the front entrance where Talkatoo and the Water Plaza Entrance Checkpoint Flag can be found.

Bubblainians, Volbonans, and a New Donker visit the Water Plaza after the main story's completion. The plaza's architecture resembles ancient ruins, featuring many tall pillars and crumbled stone. Though it is underwater, the interior of the Water Plaza is mostly dry, despite there being nothing separating the plaza's entrances from the lake's water. It is a domed underwater plaza on the west end of Lake Lamode inhabited by Lochladies. The Water Plaza is a location in the Lake Kingdom in Super Mario Odyssey.
