The complexity of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's space.

New waterproofing membrane is laid down before any finish material goes in. Plumbing is adjusted to fit the new showerhead location and any additional fixtures you add.
