We shopped around for a glass enclosure for a new bath we were installing.  We couldn't justify the cost of a custom glass enclosure along with the price of a shower base for a spare bath, so we decided to give Vigo a shot.   We couldn't be happier.  The glass is as thick as what we have in our custom fit master bath and the hardware is exceptional.  Be sure to choose the correct product based on where your drain exists.  You'll also need at least two people getting this into your house.  The glass is not just thick, but is very heavy.
