assembly is pretty easy get a long 3 1/2in (91mm) water-proof 3m strip. place it on the back then stick to the bathroom shower/tub wall and use freely.
PLA is waterproof as most people know so print this in the right orientation for a really strong part. i also suggest going 100% infill for extra support.
It is originally meant for loofas, but it can be used for anything shower related. just stick on a smooth wall and use. easy as that.
