Let's get started to see 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 drain assembly — is removed and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's space.

On a structural level, the process involves capping the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then constructing the new shower floor with a correct slope toward the shower drain. New waterproof liner is installed before any tile, stone, or prefab panel goes in. Plumbing is modified to serve the new showerhead location and any extra spray features you choose.

The finished product is a code-compliant shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a thorough improvement to your bathroom's structure and usability.

Key Benefits of a Tub to Shower Conversion

• Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a custom shower stall returns that room to usable, accessible bathroom space.
• Better Mobility Access — A tub to shower conversion can include a barrier-free floor transition, safety rails, and a fold-down bench to support aging adults, people with disabilities, or anyone recovering from surgery.
• Faster Morning Routines — Most people shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you really live.
• Better Return on Investment — Updated bathrooms consistently rank among the top home improvements for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
• Lower Maintenance Demands — Shower surrounds and bases are often simpler to clean and maintain than a standard bathtub with a surrounding tile enclosure.
• Personalized Finish Choices — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion opens up many more design options than a prefab tub kit.
• Reduced Water Use — Soaking in a tub uses roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
• Lasting Construction — When Brother & Brother Builders installs a tub to shower conversion, the structural components are designed for durability for decades.

The Tub to Shower Conversion Procedure Step by Step

1. In-Home Evaluation and Scope Review — A remodeling specialist visits your home to assess your existing tub, plumbing, and bathroom layout. We discuss your goals, design preferences, and budget so the project plan aligns with exactly what you need.
2. Demolition and Removal — The existing fixtures and surrounding structure are carefully removed. Existing water supply tied to the old tub are disconnected, capped, or rerouted to set the stage for the new shower plumbing layout.
3. Building the Shower's Foundation — This is widely considered the most important stage of a tub to shower conversion. New cement board or tile backer is attached to the wall studs, and a continuous waterproof layer is applied across every area that will contact water. The floor base is sloped correctly to avoid standing water.
4. Plumbing Rough-In and Fixture Placement — Our plumbing team position the new plumbing fixtures according to your fixture selections. Whether you chose a basic or premium shower setup, everything is positioned at this point.
5. Finishing the Shower Walls and Floor — Tile setters apply your preferred wall and floor covering using professional-grade installation materials. Every tile edge is finished and reviewed before the enclosure goes in.
6. Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we hang your shower door or curtain hardware. Every mounting bracket is secured correctly to prevent loosening over time.
7. Final Inspection, Grouting, and Caulking — Once the full shower is finished and installed, we conduct a careful quality review. All caulk joints at the base and wall corners are caulked with flexible waterproof sealant. We walk you through the completed project and make sure everything meets your expectations.

Who Is a Strong Candidate for a Tub to Shower Conversion?

Our team at our firm will always be honest if a tub to shower conversion is not the right fit for your specific layout.
