What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and hardware — is removed and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's square footage beyond the original tub's space.
On a technical level, the work involves capping the existing tub drain and supply lines, lifting the tub shell and any surrounding wall material that was tied to it, then building out the new shower base with a correct slope toward the drain. New moisture barrier is installed before any surface covering goes up. Plumbing is modified to fit the new showerhead location and any additional fixtures you add.
The outcome is a code-compliant shower that performs reliably for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a fundamental transformation to your bathroom's structure and usability.

- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
- Easier Cleaning — Shower surrounds and bases are often simpler to keep spotless than a full-length bathtub with hard-to-reach corners.
- Personalized Finish Choices — From subway tile surrounds to frameless glass doors, a tub to shower conversion opens up many more design directions than a standard tub surround.

New cement board or tile backer is screwed to the structural framing, and a industry-standard moisture barrier is applied across every area that will contact water. The shower pan is graded toward the drain to avoid standing water.
