Thank you for your question. We do recommend installing the door jambs of the Delta Round Corner Shower Enclosure B911917-3838-SS model, over the existing tile. As installing the tile on either side of the jambs could potentially create leak points. Please see page 3 module 3 of the below Maintenance/Installation document link. Please feel free to call, email, or message us on social, if there is anything else you need.
