I bought this last year to replace an old shower stall. Had it installed by a contractor who has done ton of work at our place. He said the installation for fairly straight-forward. but the shower door kept on leaking despite applying lenient quantity of waterproof sealant. the door does not close without having to lift it up while pulling it close. I contacted manufacturer to get the solution on leaks and door. But they didnt respond for couple of weeks and then didnt provide any helpful solutions. It seems you would have to drill "weep holes" on the frame. my question is if it is required then why was it not included in the installing instructions. I see the hard vinyl base has a depressed area - so appears to be a manufacturing defect. They didnt provide any solution for door situation. And didnt respond to followup email. Very disappointed.
