Thinking About 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 day. For a growing number of homeowners, the standard bathtub takes up valuable floor space while sitting empty for months at a time.

Whether you are aging in place or simply want a more accessible shower setup, this guide walks you through all the details — from how the conversion works to what makes someone an perfect candidate. Keep reading to find out whether a tub to shower conversion is the right move for your home.
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 framing and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scale of the project varies based on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a structural level, the project involves rerouting the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower pan with a correct slope toward the center drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes up. Plumbing is rerouted to fit the new showerhead height and any additional fixtures you add.
The finished product is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental transformation to your bathroom's structure and usability.
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 frees up that square footage to usable, open bathroom space.
- Better Mobility Access — A tub to shower conversion can include a low-threshold or curbless entry, grab bars, and a shower bench to accommodate those who need a safer bathing solution.
- Quicker Showers — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion matches your space with how you really live.
- Better Return on Investment — Updated bathrooms reliably appear among the top home improvements for resale. A tub to shower conversion communicates updated finishes to future owners.
- Lower Maintenance Demands — Shower surrounds and bases are typically faster to keep spotless than a full-length bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion unlocks significantly broader design directions than a standard tub surround.
- Water Efficiency — Filling a bathtub consumes roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- Structural Longevity — When our team builds a tub to shower conversion, the underlying systems are designed for durability through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A project consultant comes to your bathroom to assess your existing fixtures and framing. We discuss your wishlist and timeline so the project plan reflects exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are demolished and cleared. Any plumbing connections tied to the old tub are properly shut off to make room for the new shower plumbing layout.
- 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 screwed to the wall studs, and a continuous waterproof layer is installed across every area that will contact water. The shower pan is graded toward the drain to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew install the new rough-in plumbing according to your design plan. Whether you selected a standard showerhead or an upgraded fixture package, everything is roughed in at this phase.
- Finishing the Shower Walls and Floor — Tile setters install your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every seam is grouted and checked before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we install your chosen enclosure system. Each component is anchored properly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once all surfaces is complete, we do a careful final inspection. Every seam at corners and the floor-to-wall transition are finished with flexible waterproof sealant. We show you the completed project and verify everything is exactly what you wanted.
Who Is a Strong Candidate for a Tub to Shower Conversion?
Homeowners who rarely or never use their bathtub are usually perfect for a tub to shower conversion. This includes homeowners who struggle with high tub walls — a zero-entry walk-in shower is among the most meaningful accessibility modifications you can make to your bathroom. Parents of toddlers who previously needed the tub for baths may find value in a conversion once the kids are past the bathtub stage.
A tub to shower conversion also makes sense for anyone with a narrow or tight bathroom footprint where the tub dominates the floor plan. Eliminating the bathtub and putting in a custom shower can make a small bathroom feel significantly larger. Keep in mind, if your property has no other tub, maintaining a soaking option is worth discussing before scheduling demolition.
Those who see the greatest return from a tub to shower conversion are those planning to stay in the home long-term as well as those staging for the real estate market and looking for a bathroom that reads modern and updated. Our experts at our firm will tell you plainly if a tub to shower conversion is not the best call for your home.
