I know that this reply is not directly applicable to the main subject here, but I want to give my point of view on the 2350 vs the 2552 shower. We had a 2350 before we purchased our 2552, so I've experienced both. Maybe it's because of my size (only 5'6" and 138 lbs.), but I much prefer the shower in the 2552. There's plenty of room inside for a great shower and I prefer the hinged door rather than the accordion one. I do like to open the door to make more space when making my final towel down before stepping out of the shower.
