These shots are from stateroom 6654 on the Magic. Most of the bathrooms do NOT have the combo of both tub and roll in shower. Both me and friend who came along are wheelchair users and had no problem what so ever in using the bathroom. Basically felt no difference on that department between land or sea, apart from the toilet making more noice onboard.

Also no flooding -unlike some have reported-, so I could safely transfer to and from the toilet after friend had just taken a shower.
Shower is to the left when looking into the bathroom, toilet right in front and tub to the right. Door also has grab bars on them on the inside.
