The ground-water is a solution of calcium carbonate it has dissolved from the limestone above the cave. The mineral is subsequently precipitated as deposits of calcite in the cave: stalatcties & stalagmites, and flowstone on the floor and walls.
I'm not really sure what you had in mind. Given that the cave is in limestone (as the vast majority of them are) there has to be a dimensional limit to the dissolution and erosion processes. The floor is there by default: it is the lowest surface along a passage at that given time in the cave's development.

Stalagmites are the type of speleothems found in limestone caves that grow upward from the floor. They form as mineral-rich water drips from the ceiling and deposits calcium carbonate on the cave floor, gradually building up over time.
Yes, groundwater can erode in the formation of stalactites and stalagmites in caves. Groundwater dissolves minerals like calcium carbonate as it moves through rocks, then deposits these minerals as it drips from cave ceilings to form stalactites. As the mineral-laden water drips onto the cave floor, it leaves behind deposits that build up to form stalagmites.
Yes, the formation of stalactites and stalagmites occurs in the zone of saturation. Groundwater drips through the ceiling of a cave and leaves behind mineral deposits when the water evaporates, forming stalactites. When the water drips onto the cave floor, it leaves deposits that build up into stalagmites.

A limestone deposit rising from the floor in a cave is most likely a formation called a stalagmite. Stalagmites are formed when mineral-rich water drips from the ceiling of a cave, depositing calcite and building up over time. Over thousands of years, stalagmites can grow tall and take on various shapes.

A cave?
In a cave? Yes, almost - it's actually the calcium carbonate, the main constituent of limetsone, that is dissolved by the ground-water then precipitated as calcite to form stalactites and stalagmites, and similar deposits.
Stalagmites
Stalagmites are the type of speleothems found in limestone caves that grow upward from the floor. They form as mineral-rich water drips from the ceiling and deposits calcium carbonate on the cave floor, gradually building up over time.
Groundwater affects cave formation by dissolving minerals in the rock, creating passageways and chambers. Over time, this process can lead to the formation of stalactites, stalagmites, and other cave formations. Additionally, groundwater can contribute to the erosion of cave walls and ceilings, shaping the overall structure of the cave.

The opening formed when acid groundwater dissolves limestone is called a karst landscape. This process creates features such as caves, sinkholes, and underground rivers due to the chemical weathering of limestone by acidic water.
They are formed by the deposit of minerals. They are left behind by evaporation.
