The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's location.
On a structural level, the project involves capping the existing tub drain and supply lines, removing the tub shell and any surrounding wall material that was tied to it, then constructing the new shower floor with a code-compliant slope toward the shower drain. New waterproofing membrane is applied before any finish material goes in. Plumbing is adjusted to serve the new showerhead height and any extra spray features you select.
The result is a structurally sound shower that performs reliably for the long term. A tub to shower conversion done right is not just a visual change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.
