I purchased the Pocket Tarp w/ Storm Doors last year along with the Solo Plus bathtub groundsheet. I've pitched it in stormy weather about five times now, and no matter the pitch, the sides of the ground sheet always flare out past the confines of the tarp and water pours into the bathtub.
My solution is to downgrade my bathtub floor from the Solo Plus to the Solo. Before I commit to spending $100 on the smaller ground sheet, does anyone with a Pocket Tarp and the Solo bathtub have problems with water flowing in?
