Let's get started to find out whether a tub to shower conversion is the best option for your home.

What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and drain assembly — is taken out and replaced with a purpose-built shower unit. The complexity of the project depends on your existing bathroom layout, your style choices, and whether you need to expand the shower's footprint beyond the original tub's space.

On a technical level, the work involves capping the existing tub drain and supply lines, removing the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a correct slope toward the shower drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes on. Plumbing is rerouted to serve the new showerhead position and any extra spray features you select.

The outcome is a code-compliant shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a thorough upgrade to your bathroom's infrastructure and finish.

Top Benefits of a Tub to Shower Conversion

• Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower restores that square footage to usable, accessible bathroom space.
• Improved Accessibility — A tub to shower conversion can include a barrier-free floor transition, safety rails, and a shower bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
• Quicker Showers — Most people shower far more often than they bathe. A tub to shower conversion matches your space with how you actually use it.
• Stronger Home Appraisals — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
• Simpler Upkeep — Shower pans, walls, and glass enclosures are generally easier to clean and maintain than a deep-soaking bathtub with grout lines on all four sides.
• Personalized Finish Choices — From subway tile surrounds to semi-frameless enclosures, a tub to shower conversion unlocks far more design options than a one-piece tub unit.
• Lower Utility Bills — Running a full bath requires roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
• Structural Longevity — When our team completes a tub to shower conversion, the structural components are constructed to hold up well beyond 20 years.

The Tub to Shower Conversion Procedure Step by Step

1. Initial Consultation and Planning — A project consultant visits your home to measure your existing space and infrastructure. We review your goals, design preferences, and budget so the project plan matches exactly what you have in mind.
2. Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are taken out. Existing water supply tied to the old tub are properly shut off to make room for the updated fixture configuration.
3. Building the Shower's Foundation — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is attached to the framing, and a industry-standard moisture barrier is applied across all wet surfaces. The shower pan is sloped correctly to prevent pooling.
4. Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new rough-in plumbing according to your chosen layout. Whether you chose a basic or premium shower setup, everything is roughed in at this phase.
5. Tile, Stone, or Panel Installation — Our finish crew set your preferred wall and floor covering using professional-grade installation materials. Every grout joint is sealed and inspected before the enclosure goes in.
6. Hanging Doors, Glass, or Hardware — Depending on your preference, we mount your chosen enclosure system. All hardware is set into the tile or framing to ensure years of smooth, wobble-free operation.
7. Final Inspection, Grouting, and Caulking — Once everything is complete, we perform a careful final inspection. Each transition joint at the base and wall corners are finished with mold-resistant silicone caulk. We review with you the final result and verify everything looks and functions as planned.
