Sanicomfort Shower Hose Swivel Connector 1925270 by sanicomfort

It's expensive, but does the job. The shower hose never seemed to lay flat against the shower wall, so you either lived with or twisted it until it was as flat as possible. This solved the problem. It's snug enough that it doesn't rotate on its own, you will need to give it a gently twist. I positioned it directly below the handheld shower head, followed by the "Aquafaucet S-002 Shower Head Shut Off Valve" (Amazon). This also allows you to position the shut off lever to the most convenient location. I would purchase it again. 4 stars only because it was rather expensive.
