Some nouns like "apple" and "watermelon" are sometimes count nouns, and sometimes non-count nouns, depending on how we're thinking about them, not whether they're solid or broken.
When we're thinking of individual pieces of fruit, "apple" and "watermelon" are count nouns:
I have an apple in my lunch.
We almost ate a whole watermelon.
When we think of them as ingredients or a general substance, they are non-count nouns:
This pie needs more apple.
There's watermelon all over the lawn.
With "mirror", generally speaking, when it's broken, we don't think of it as a mirror anymore because it doesn't reflect images, so it's not a mirror. We think about it as a general substance:
"Our living room mirror broke, and now there's glass all over the carpet."
Mirrors stop being mirrors when they break, and become glass.
You could potentially use "you've got mirror all over the floor" as a humorous/slang-like expression ("you've got" in this sentence meaning "you have caused there to be").
As explained by other answers, it isn't grammatically correct English but it does have a comical aspect to it, perhaps even invoking surreal connotations (think Salvador Dalí's Persistence of Memory painting).
There are pieces of the mirror on ground, and the mirror is a specific object which is shattered. Thereby, "the" has to be added in front of mirror. or Broken mirrors can be described as pieces of the mirror
One of each fruit. If there is more than one piece of fruit the plural verb "are" should be used.
The same principle applies to a mirror which is a countable noun
More than one mirror becomes
If one of the three mirrors falls and breaks…
From the net
…for diamonds are bought and worn for the same reason that magpies assume unto themselves such things as bits of tin and broken mirror glass simply because they glitter, and glitter more than any other substance.
He took the broken pieces of mirror and began to fit them onto the entrance wall, one piece at a time, as though he were constructing a mosaic.
Lil kneels on the floor and picks up the broken pieces of mirror
Moreover , the young dancers are dressed in costumes made up of bits of mirror which "flash and sparkle as they move"
Mirror and glass are not the same, the former is countable while the latter, a substance, is uncountable. So while the phrase "There's glass…" is grammatical, the same cannot be said for "There's mirror” even when that object is broken or shattered (into pieces).

In addition to the other excellent answers - I would note that nouns and even proper nouns are sometimes used informally as non-count nouns for comedic effect.
For example:
My car exploded! Now there's car all over the road.
