The scope of the project depends on your existing bathroom layout, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's position.

New waterproofing membrane is laid down before any finish material goes in. Plumbing is modified to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The result is a structurally sound shower that drains correctly for many years. A tub to shower conversion done correctly is not just a visual change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
