Very happy with this shower so far.  Bought it because of limited bathroom space for me; circular door takes less space than a front-opening door.  Back ordered and had to wait until Ove production caught up.  15% price difference between two big-box stores.  Seems to be several versions of installation manual; contractor used what came with delivered product.  Didn't seem to be any problems with installation.  Had to add behind-wall support for safety grab bars; good thing contractor knew I wanted those installed before putting shower enclosure up.  Happy with purchase..
