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 hardware — is demolished and replaced with a professionally installed 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 position.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a proper slope toward the center drain. New waterproofing membrane is applied before any surface covering goes on. Plumbing is rerouted to serve the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The outcome is a structurally sound shower that drains correctly for many years. A tub to shower conversion done right is not just a surface-level change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion

- Faster Morning Routines — Most people shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you really live.
- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Lower Maintenance Demands — Shower floors and walls are generally easier to clean and maintain than a full-length bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up far more design options than a standard tub surround.

The Tub to Shower Conversion Project Step by Step
- Initial Consultation and Planning — A remodeling specialist meets with you on-site to evaluate your existing space and infrastructure. We review your goals, design preferences, and budget so the proposal aligns with 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 properly shut off to set the stage for the revised drain placement.
- Structural Prep and Moisture Barrier Installation — This is often the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a full waterproofing membrane is applied across all wet surfaces. The shower pan is sloped correctly to ensure drainage.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new shower valve, drain body, and supply lines according to your design plan. Whether you chose a basic or premium shower setup, everything is roughed in at this point.
- Finishing the Shower Walls and Floor — Our finish crew install your preferred wall and floor covering using professional-grade installation materials. Every tile edge is finished and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we install your chosen enclosure system. Each component is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once everything is tiled, grouted, and enclosed, we conduct a thorough final inspection. Each transition joint at the base and wall corners are caulked with professional-grade caulk. We walk you through the finished shower and confirm everything looks and functions as planned.
