Thinking About a Tub to Shower Conversion? Read This First
A well-planned tub to shower conversion can fundamentally transform how you use your bathroom every single day.

What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and drain assembly — is removed and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom footprint, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's space.
On a structural level, the work involves rerouting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then framing the new shower pan with a correct slope toward the shower drain. New waterproof liner is laid down before any surface covering goes on. Plumbing is rerouted to serve the new showerhead position and any additional fixtures you choose.
The finished product is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a curbless shower restores that room to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a barrier-free floor transition, support handles, and a built-in seat to accommodate 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 really live.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to future owners.
- Simpler Upkeep — Shower pans, walls, and glass enclosures are typically faster to keep spotless than a deep-soaking bathtub with grout lines on all four sides.
- Personalized Finish Choices — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion unlocks many more design options than a one-piece tub unit.
- Reduced Water Use — Soaking in a tub consumes roughly 30 to 50 gallons of water per session. A modern shower valve 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 for decades.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist meets with you on-site to assess your existing space and infrastructure. We discuss your goals, design preferences, and budget so the scope of work matches exactly what you need.
- Demolition and Removal — The existing tub unit and wall material are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to make room for the new shower plumbing layout.
- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the framing, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The drain area is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Our plumbing team install the new plumbing fixtures according to your fixture selections. Whether you chose a basic or premium shower setup, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — Our finish crew set your preferred wall and floor covering using professional-grade installation materials. Every tile edge is grouted and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we install your chosen enclosure system. Every mounting bracket is anchored properly to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once the full shower is tiled, grouted, and enclosed, we conduct a thorough walk-through. Each transition joint at the base and wall corners are caulked with professional-grade caulk. We show you the completed project and confirm everything looks and functions as planned.
