replace some of the uprights with shorter ones.

Is that anything like a readily-available inexpensive standard size in
any suitable material (the I.D. does not matter, except that the wall
must give reasonable rigidity)?

To help you to envisage it, that O.D. is about 50% bigger than that of
a proper wooden broom- or mop- stick.


1.5" waste pipe?


Close. I.D. 38 mm, O.D. 42 mm, to judge by the plumber's offcut that I
have to hand. Thanks for trying!

1 1/4" plus duct tape? 1 1/4" plus solvent weld straight connectors?
Haven't chtecked the latter but must be prettty close.
