What Exactly 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 drain assembly — is taken out and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom footprint, your style choices, and whether you need to expand the shower's usable area beyond the original tub's space.
On a structural level, the work involves rerouting the existing tub drain and supply lines, taking out the tub shell and any old tile surround that was tied to it, then building out the new shower floor with a proper slope toward the center drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes on. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The outcome is a fully waterproofed shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a visual change — it is a thorough transformation to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs occupy between 13 and 16 square feet. Converting to a walk-in shower restores that room to usable, open bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a barrier-free floor transition, support handles, and a fold-down bench to accommodate homeowners with limited mobility.
- Quicker Showers — Most people shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you really live.
- Better Return on Investment — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to future owners.
- Easier Cleaning — Shower floors and walls are often simpler to scrub and wipe down than a standard bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From subway tile surrounds to frameless glass doors, a tub to shower conversion unlocks many more design options than a prefab tub kit.
- Lower Utility Bills — Soaking in a tub requires roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can cut that to as little as 15 gallons.
- Structural Longevity — When our crew completes a tub to shower conversion, the waterproofing, substrate, and finish materials are constructed to hold up for decades.
The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A project consultant comes to your bathroom to assess your existing space and infrastructure. We review your goals, design preferences, and budget so the project plan reflects exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Existing water supply tied to the old tub are professionally handled to prepare for the revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a full waterproofing membrane is applied across all wet surfaces. The shower pan is pitched properly to prevent pooling.
- Installing New Shower Plumbing — Our plumbing team position the new rough-in plumbing according to your chosen layout. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this phase.
- Tile, Stone, or Panel Installation — Tile setters install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is finished and reviewed before moving to the next phase.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is anchored properly to prevent loosening over time.
- Completion Walk-Through and Finishing Touches — Once everything is complete, we conduct a careful final inspection. Every seam at corners and the floor-to-wall transition are sealed with flexible waterproof sealant. We walk you through the final result and verify everything is exactly what you wanted.
