I sit on a marble perch,
A fall once caused my great hurt.
Around me, Spanish tiles softly gleam,
Hand-fired gray, a muted dream.
Below, a matching bench invites a rest,
All Calacatta marble, put to the test.
A long, thin linear channel drinks the spray,
When water washes cares away.

What am I?

... Humpty Dumpty in a luxurious shower!

The client surprised me with this! Love it.
