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 hardware — is removed and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom layout, your finish selections, and whether you want 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, removing the tub itself and any old tile surround that was tied to it, then constructing the new shower base with a correct slope toward the center drain. New waterproofing membrane is laid down before any surface covering goes on. Plumbing is rerouted to serve the new showerhead height and any body sprays, handheld wands, or rain heads you choose.
The finished product is a code-compliant shower that drains correctly for many years. A tub to shower conversion done right is not just a surface-level change — it is a fundamental upgrade to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower frees up that area to usable, accessible bathroom space.
- Better Mobility Access — A tub to shower conversion can feature a zero-entry design, grab bars, and a shower bench to assist those who need a safer bathing solution.
- Faster Morning Routines — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Better Return on Investment — Updated bathrooms consistently rank among the top home improvements for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Simpler Upkeep — Shower surrounds and bases are often simpler to keep spotless than a full-length bathtub with a surrounding tile enclosure.
- Tailored Aesthetic Selections — From natural stone slabs to frameless glass doors, a tub to shower conversion creates room for many more design options than a one-piece tub unit.
- Water Efficiency — Soaking in a tub uses roughly 30 to 50 gallons of water per session. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Lasting Construction — When our team completes a tub to shower conversion, the underlying systems are constructed to hold up for decades.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to assess your existing space and infrastructure. We discuss your goals, design preferences, and budget so the proposal reflects exactly what you want.
- Removal of the Existing Tub and Surround — The existing tub unit and wall material are taken out. Existing water supply 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 arguably the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the wall studs, and a full waterproofing membrane is installed across the shower floor and lower walls. The floor base is graded toward the drain to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew install the new shower valve, drain body, and supply lines according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is positioned at this stage.
- Finishing the Shower Walls and Floor — Our finish crew install your preferred wall and floor covering using professional-grade installation materials. Every grout joint is grouted and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we hang your chosen enclosure system. Every mounting bracket is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once all surfaces is complete, we do a careful walk-through. All caulk joints at the base and wall corners are caulked with flexible waterproof sealant. We show you the completed project and confirm everything looks and functions as planned.
