Considering a Tub to Shower Conversion? Here's What You Should Know
A well-planned tub to shower conversion can completely change how you use your bathroom every single morning.

Let's get started to find out whether a tub to shower conversion is a smart choice for your home.
What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom plumbing configuration, your design preferences, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a technical level, the project involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any surrounding wall material that was tied to it, then framing the new shower floor with a proper slope toward the drain. New waterproof liner is laid down before any surface covering goes on. Plumbing is adjusted to fit the new showerhead location and any additional fixtures you select.
The result is a code-compliant shower that functions properly for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete transformation to your bathroom's structure and usability.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall frees up that area to usable, open bathroom space.

- Better Return on Investment — Updated bathrooms consistently rank among the top home improvements for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Easier Cleaning — Shower floors and walls are generally easier to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Custom Design Options — From subway tile surrounds to frameless glass doors, a tub to shower conversion creates room for far more design possibilities than a standard tub surround.

- Initial Consultation and Planning — A remodeling specialist meets with you on-site to evaluate your existing space and infrastructure. We go over your goals, design preferences, and budget so the scope of work matches exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are carefully removed. Existing water supply tied to the old tub are professionally handled to set the stage 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 fastened to the framing, and a continuous waterproof layer is rolled or troweled on across the shower floor and lower walls. The floor base is pitched properly to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew set the new shower valve, drain body, and supply lines according to your fixture selections. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this phase.
- Tile, Stone, or Panel Installation — Tile setters apply your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is finished and checked before moving to the next phase.
- Installing the Shower Enclosure — Depending on your design choice, we mount your chosen enclosure system. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once all surfaces is tiled, grouted, and enclosed, we perform a room-by-room walk-through. All caulk joints at corners and the floor-to-wall transition are finished with flexible waterproof sealant. We show you the completed project and verify everything looks and functions as planned.
