Very heavy, well made doors and soooooo sorry no one was present to help my installer up the stairs with these doors other than the woman with back issues! I would love to give this shower door 5 stars just because of how well made it is, but due to either a bad installation due to the quality of the instructions and/or missing parts, we have had and are still experiencing issues with water flowing onto the bathroom floor. It was pouring out, but we have got it down to a slow seep, now. Quite attractive and hopeful of getting these issues sorted soon.
