Value trade-offs
FerdY's 7mm acrylic walls vs Woodbridge's 8mm: the 1mm difference is not visually apparent, but results in slightly less structural rigidity when full and occupied. In practice, the flex is minimal in normal use. The non-adjustable feet are a more practical concern -- in older bathrooms where floors are not perfectly level, shimming FerdY's fixed feet is less convenient than adjusting Woodbridge's threaded feet. If your bathroom floor is level, FerdY's feet are fine. If not, budget extra time for shimming or choose Woodbridge.
