Thanks folks! All this input should help alleviate DW's concerns about the corner shower. And X3 on not having everything wet like in the PUP.
We plan to add the Oxygenics (per FRF users recommendations) as well as the extendable shower rod, corner splash guards & velcro, etc.
But honestly, I think having a "real" bathroom (with its own sink!) is such a huge jump up from the popup that it will more than offset any minor quibbles.
Now if I can just get DW to moderate her water usage! I can't tell you how many tons of water I have carried between our trailer and the bathrooms while doing our weekly stays in Yosemite over the last 7 years. I think you can tell where we have stayed by the well-worn paths between us and the sinks!
