Van Hise Rock was named for the preeminent geologist of the 19th century, Charles Richard VanHise, who was also president of the University of Wisconsin-Madison from 1903-1918. VanHise used this rock to show the major structural features of metamorphic* Precambrian* rock and also to demonstrate the kinds of changes that occur in rocks through mountain building periods.
The requirement for seat height, however, is very simple: The top of the seat must be a minimum of 17 inches and a maximum of 19 inches above the shower floor.
A shower that is too big will just end up wasting space. Showers without doors are also an option. In a 4 x 5 area, this feature can make it seem more spacious. A 3.5 x 5.1 area is good enough for two individuals. But if you want to add a bench, the length or width has to be increased. There are many other shower sizes that can be used. A 36â x 36â size will be fine for a single individual (provided they are of average height). For couples, 40â x 60â is ideal.
