Presumably this was permitted in previous installations?

The shower is now out of order, and it is likely a new shower will be
required. Is it still permitted to leave the cable in this position, or
should it be buried in the wall?

Unprotected surface wiring, not OK - and hasn't been for a long time
AFAIK.

Also sounds like it's flexible cable, rather than solid core.

If it's surface, should be in trunking.

Given it's potentially the most hazardous electrical installation in
the home, I'd prefer to see a single piece of cable, no joins, running
from the CU (with RCD/RCBO), to right inside the shower unit, with no
possibility of fingers or moisture getting near the cable or its
connections.
