Thinking About a Tub to Shower Conversion? Here's What You Should Know
A well-planned tub to shower conversion can fundamentally transform how you use your bathroom every single week.

Whether you are downsizing or simply prefer a more accessible shower setup, this overview walks you through the full picture — from how the project works to what makes someone an perfect candidate. Let's get started to learn whether a tub to shower conversion is the right move for your space.
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 hardware — is removed and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a structural level, the process involves capping the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then constructing the new shower pan with a correct slope toward the center drain. New waterproof liner is installed 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 add.
The finished product is a code-compliant shower that performs reliably for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a complete upgrade to your bathroom's infrastructure and finish.
Major Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs consume between 13 and 16 square feet. Converting to a curbless shower restores that room to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a barrier-free floor transition, grab bars, and a built-in seat to assist homeowners with limited mobility.
- More Efficient Daily Bathing — Most people shower significantly more than they bathe. A tub to shower conversion redesigns your layout with how you actually use it.
- Higher Resale Value — Updated bathrooms always show up among the top home improvements for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Simpler Upkeep — Shower floors and walls are typically faster to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Personalized Finish Choices — From subway tile surrounds to semi-frameless enclosures, a tub to shower conversion creates room for significantly broader design possibilities than a prefab tub kit.
- Reduced Water Use — 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 under 20 gallons per shower.
- Structural Longevity — When Brother & Brother Builders completes a tub to shower conversion, the structural components are built to last well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A member of our team visits your home to evaluate your existing space and infrastructure. We go over your wishlist and timeline so the project plan aligns with exactly what you want.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Existing water supply tied to the old tub are professionally handled to make room for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is often the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is attached to the framing, and a continuous waterproof layer is applied across the shower floor and lower walls. The drain area is graded toward the drain to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Our plumbing team position the new shower valve, drain body, and supply lines according to your chosen layout. Whether you chose a standard showerhead or an upgraded fixture package, everything is installed at this phase.
- Applying Your Chosen Finish Materials — Our finish crew apply your preferred wall and floor covering using professional-grade installation materials. Every tile edge is sealed and reviewed before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your chosen enclosure system. Each component is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we do a thorough final inspection. Each transition joint at the perimeter are sealed with professional-grade caulk. We walk you through the completed project and verify everything looks and functions as planned.
