Horrible experience as the product size specifications on the downloaded pdf from site is actually different from the manual included in box. In box size installation hole is 11 732” square.  Website pdf shows 14 68”
My planned hole is now too large and we just completed the drywall!   Some might say, you should’ve had this on hand before install - well it was going to be until Wayfair sent me an incorrect labeled desk stand box instead of the actual shower unit. Pushed back the delivery another 5 days and the subs for drywall were already scheduled.
