Thank you for your feedback. DreamLine continually is working to improve and update our installation manuals. As you can imagine, it is a process that takes a lot of time. If you would like to drop us an email outlining the areas of the manual that you had difficulty with, we will be happy to forward this to our Engineering Team to address. The most recent manual can be found on our website, which is listed on the front of your manual. We also place our Customer Support phone number and email address on the front of our manual, should you have any questions or need clarification of instructions during the installation. We hope that you took advantage of this during the installation. Thank you for choosing DreamLine and for your review.
