Depending on your choice of cabin, those cabins up to the grade of minisuite, have a shower enclosure with a step of about 3 inches and a flimsy ( clingy ) curtain. Minisuites only have a bath tub with a shower head over it. Full suits have a fully glassed panelled enclosure with a 4 inch step along with a separate bath. We travel in full suits and if we can’t get an accessible wet room cabin, we take 2 suction type handles and a suction type shower head holder, these fix to the glass panels, we then get customer service to get the plumber to change the fixed high up shower head to a flexible pipe one. To overcome the step of about 4 inches we take a folding 2 inch high step with us. Hope this helps.
