Thank you for your question on the Delta 60" x 32" Bathtub - Left Drain. I will be happy to assist you today.
This tub is meant to be installed flat on the sub-floor. If you are installing tile, you will want to bring the tile next to the tub edge but not under it.
I hope this has answered your question. If you ever have any questions, concerns, or require anything further please feel free to give us a call at 800-345-3358 and we will be happy to assist you in any way that we can.
