What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a custom-fitted shower unit. The scale of the project depends on your existing bathroom footprint, your style choices, and whether you want to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a correct slope toward the shower drain. New waterproof liner is installed before any finish material goes on. Plumbing is modified to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The outcome is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done right is not just a visual change — it is a complete upgrade to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion

- Easier Cleaning — Shower surrounds and bases are generally easier to clean and maintain than a deep-soaking bathtub with hard-to-reach corners.
- Personalized Finish Choices — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion creates room for far more design options than a one-piece tub unit.

The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A project consultant comes to your bathroom to assess your existing fixtures and framing. We review your must-haves and finish choices so the project plan reflects exactly what you have in mind.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to prepare for the new shower plumbing layout.
- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the framing, and a full waterproofing membrane is rolled or troweled on across all wet surfaces. The floor base is sloped correctly to ensure drainage.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this phase.
- Finishing the Shower Walls and Floor — Tile setters install your selected finish material using the correct adhesive and grout system. Every seam is finished and checked before moving to the next phase.
- Installing the Shower Enclosure — Depending on your preference, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once everything is complete, we conduct a thorough quality review. All caulk joints at the perimeter are caulked with professional-grade caulk. We walk you through the final result and verify everything is exactly what you wanted.
