We recently stayed in a handicap accessible balcony cabin on the Royal Princess. For those wanting to know what these cabins look like, I've got plenty of photos for you. This particular cabin is A303 on the starboard side of the ship and is designated as a BB cabin. We've also stayed in A302 on the port side and the cabin set up is exactly the same. These cabins can accommodate up to four passengers with upper berths. The bunk beds are fully recessed into the ceiling and cause no obstruction at all.
I've added a couple notes about some of the features of the cabin with corresponding pictures.
The sink was a bit smaller than what we've come to expect on the Royal Princess and the storage space wasn't ideal as the shelves were high and smaller.
The bar separating the toilet from the shower could be lowered and raised as needed.
The shower had a bench that could be raised or lowered as well.
Even the shower head height was adjustable.
The back of the bathroom door had a grab bar and there were knobs for hanging clothes at two different heights.
As this was a balcony cabin they had made adjustments to make it accessible.
Because of hubby's cerebral palsy and difficulty with mobility and the steps into the bathroom and shower in the standard cabins, we probably could have been requesting accessible cabins for all our past cruises. We never once have, wanting to leave them for someone who needs them more than he does. Even these accessible cabins in the photos were not requested by us. (We booked guarantee cabins at the very last minute and these were the cabins we were assigned to us.) However, for the first time ever we have asked for an accessible cabin for an upcoming mini suite booking. (As an FYI on minisuites - they have a tub/shower combo. As hubby's unable to climb over a tub to get into a shower, an accessible cabin was our only option.) I will be posting photos of that cabin next month.
