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 demolished and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom footprint, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's location.
On a structural level, the process involves disconnecting the existing tub drain and supply lines, removing the tub unit and any surrounding wall material that was tied to it, then framing the new shower base with a proper slope toward the drain. New waterproofing membrane is applied before any surface covering goes up. Plumbing is adjusted to serve the new showerhead location and any body sprays, handheld wands, or rain heads you select.
The result is a structurally sound shower that functions properly for many years. A tub to shower conversion done right is not just a visual change — it is a complete transformation to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion

- Lower Maintenance Demands — Shower floors and walls are typically faster to keep spotless than a standard bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion unlocks far more design possibilities than a one-piece tub unit.

The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A member of our team visits your home to measure your existing tub, plumbing, and bathroom layout. We go over your wishlist and timeline so the proposal reflects exactly what you have in mind.
- Tub Extraction and Teardown — The existing tub unit and wall material are taken out. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to set the stage for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is often the most important stage of a tub to shower conversion. New waterproof backer material is attached to the framing, and a continuous waterproof layer is rolled or troweled on across every area that will contact water. The floor base is pitched properly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew install the new shower valve, drain body, and supply lines according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this stage.
- Tile, Stone, or Panel Installation — Our finish crew install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every seam is sealed and reviewed before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we install your shower door or curtain hardware. Each component 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 careful quality review. Each transition joint at the base and wall corners are caulked with professional-grade caulk. We show you the final result and make sure everything meets your expectations.
