I got a quote of over $12,000 to change a soaking tub into a shower. I have lots of DIY experience, although my age is now limiting my strength. I decided myself and another family member would do the work ourselves. We’ve done pretty good so far but when he installed the trackless shower doors, he wasn’t able to get the shower doors plumb. The walls are plumb, the top rail is level, but the doors are not. They only passively slide to one side. I’ve tried YouTube, but am unable to find a solution. The brand is Craft + Main - Lagoon 60” shower door. Anyone with experience have any suggestions? #diy source
