What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a custom-fitted shower unit. The complexity of the project is shaped by your existing bathroom layout, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, taking out the tub unit and any old tile surround that was tied to it, then framing the new shower base with a correct slope toward the shower drain. New waterproofing membrane is installed before any surface covering goes up. Plumbing is modified to accommodate the new showerhead height and any extra spray features you add.
The result is a code-compliant shower that functions properly for many years. A tub to shower conversion done right is not just a cosmetic change — it is a fundamental upgrade to your bathroom's plumbing, waterproofing, and layout.
