The shelf is white plastic and the grab bar is polished stainless steel.
It could be removed by pressing up at the bottom of the split pins on the underside but you may have a tough time getting it back into position. Due to the nature of how it mounts, it may not hold long term if you remove it more than once for cleaning.
yes, it is designed to be used in wet areas
Well, I can’t say exactly how it compares to the other shelf you speak of as there is no reference, but this particular corner shelf has been designed for the ability to “assist” people when needing something to grab onto and pull yourself up or just for something to help steady the NOT so nimble or graceful while bathing. This assist bar line up of Deltas is worth every penny and more.
