Thank you the review and choosing Aston for your remodel. We always recommend professional installation by a licensed contractor or plumber. For the vast majority of homeowners, this is not a DIY project. Regarding the hardware issue, we are constantly listening to our customers and taking their feedback with the utmost importance. But again, utilizing professional contracting would avoid the vast majority of said issues. At the end of the day, hope you enjoy the "beautiful" design, functionality and high quality of your new Aston NAUTIS GS Frameless Shower Door for years to come!
