Thank you for your feedback. The DreamLine SlimLine shower base that you purchased is designed to work with a DreamLine Shower Door and is more than high enough to work with our doors. There should be a DreamLine sticker on the inside of the shower base, facing the inside of your shower. If you would like to speak with us about your shower base, please contact DreamLine Customer Support. DreamLine's Customer Support Team can be reached by phone at 866-731-2244 or by email at support@dreamline.com. You may also reach us by LiveChat on DreamLine.com! We are available M-F from 8am-7pm EST and Saturday from 9am-5pm EST. Please give us a call and we can help you through any issue.
