Without plants and fish you can have a chlorine cleaned and sand
filtered swimming pool.

Liners come in different thicknesses and as big as you want, even
swimming pools are made with liners because they are much cheaper.

I have a cousin in Tampa that couldn't keep his doberman out of his pool
the last time I visited and there was no ramp only a shallow end.

Important facts:

I live in Las Vegas.
I want a pond with a waterfall/successive water basins.
I want the dogs to be able to get in and out easily on an inclined sand ramp
built into the bottom of the pond.
I am not (that) interested in fish or plants.
I want it for visual, and a minipool for the dogs.
I don't want to use a plastic liner pond because I want it larger than that.
