On a mechanical level, the process involves capping the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then constructing the new shower floor with a code-compliant slope toward the center drain.

7. Completion Walk-Through and Finishing Touches — Once the full shower is complete, we do a careful quality review. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We walk you through the completed project and confirm everything meets your expectations.
