DIR="$(echo ~)/Something/" would "fix" that, but...

Strictly speaking per spec this won't work. Tilde expansion happens
before

As others have pointed out, it's the unquoted tilde in the command
substitution that is expanding above. You could have used this (but
don't):
DIR="$(echo ~)/Something/"
As others have said, quoting (even double quoting) hides tilde expansion.
Just mak
I would also assume that if this command was run as root it would not
work, as root's home directory is /root. Same for any other user whose
home directory is not under /home. Perhaps a few-lines script would
first have to grep the login ID from /etc/passwd (read-only, so OK),
parse the line to get

This is POSIX shell in general.

Just DIR="$HOME/Something" unless you need to ref
While I've found a workaround, I was a bit surprised that a test for existence
of
a directory in a bash script did not work.
I tried
DIR="~/Something/"
if [ -d "$DIR" ]; then
and got that the directory did NOT exist when it was clearly there.
Workaround was to use
DIR="/home/$(basename ~)/Som
