Thank you for your question on the Delta Contemporary Corner Shelf with Assist Bar. I will be happy to assist you today.
You can install shelves on the UPstile walls with screws. If you choose to do so, please make sure to apply sealant around all the seams of the shelves to ensure a water tight seal. Also keep in mind if holes are drilled incorrectly for the screws, unfortunately we would not be able to cover that issue under warranty. I have included below a list of sealants that we recommend and are tested by our engineers:
DAP® 3.0™ Kitchen, Bath & Plumbing High Performance Sealant
Red Devil® RD3000™ Advanced Kitchen & Bath Sealant
ECO-BOND® Kitchen-Bath-Plumbing Adhesive and Sealant
We do also different models that can be used instead. They are the models 41316-RB and 41416-RB. I have included links to these below as well:
I hope this has answered your questions! If you ever have any questions, concerns, or require anything further please feel free to give us a call on our warranty line at 800-345-3358 and we will be happy to assist you in any way that we can.
