I haven't been on the Nautica yet, but I have been on other R class ships. The shower is large enough to conduct normal shower activities, turning around, raising hands over head, bending over. Unless you plan on holding a party in the shower, it will work. I grew up in a 1950s house with a walk in shower, you know, turquoise tile on the walls and a glass door that sometimes latched correctly. When I was a little kid, it seemed cavernous; when I left home as an adult, it seemed just small. Anyone who remembers those walk in showers of yore will recognize the R class shower: small but gets the job done.
