Forced Air vs Heated Floor

Have had this bathroom remodeled from 2004. Glass shower door was installed that pulls in and pushes out. The rubber gasket between the glass door and the glass wall on the hinged side won't stick to the glass about 1/4 of the way up. I've tried scraping the glass with a blade,reversing the two sided tape and cleaning the glass with alcohol prep but still no stick. Any ideas???

Hi all - I am attempting to install a shower in our basement, actually I ripped out the old one and am putting in a new one so most of the framing/plumbing was done. I bought a shower kit from costco - [url]https://www.costco.ca/Appollo-Amelia-38-in-Neo-Round-Shower-with-Base-and-Wall-Panels.product.100384637.html[/url] It is this kit but without the walls as i am using schluter kerdiboard and am going to tile myself. I have the pan in place and am going to install the kerdiboard but there is a little lip on the shower pan and i am not sure if the kerdiboard should go over this lip or if it should just come down as far as the top of the lip. the lip is about 1/4" thick and is where you screw the base to the studs so if the kerdiboard went over the lip then it would bow out a little bit at the bottom where it meets the base. but if the kerdiboard only goes to the top of the lip then there would be a gap at the shower base where the tile wont have anything to hold onto. I hope i am explaining this properly as i dont know the technical terms involved. i was thinking of maybe shaving a little off of the backside of the kerdiboard so that the kerdiboard can go over the lip and but still be level all the way down to the actual base - does this sound okay ? Thanks !
