Here is a shower holder for the iPhone XR. It uses suction cups to be held. The suction cups I got at Walmart and are the small size. The diameter of 10 mm. https://www.walmart.com/ip/Hillman-Small-Suction-Cup-Hooks-1-2lb-8-Pack/46494678 I created it out of the want to watch youtube in the shower. The area where the phone rests is 13.5mm wide and 156mm. long. It is a little larger than the phone for the case.
