What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and hardware — is demolished and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's usable area beyond the original tub's space.
On a technical level, the process involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any tile, drywall, or backer board that was tied to it, then constructing the new shower pan with a code-compliant slope toward the drain. New waterproof liner is installed before any surface covering goes on. Plumbing is modified to accommodate the new showerhead location and any additional fixtures you choose.
The result is a structurally sound shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.

- Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower restores that room to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can incorporate a low-threshold or curbless entry, grab bars, and a fold-down bench to support aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — The majority of adults shower significantly more than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Lower Maintenance Demands — Shower floors and walls are generally easier to scrub and wipe down than a full-length bathtub with a surrounding tile enclosure.
- Custom Design Options — From natural stone slabs to frameless glass doors, a tub to shower conversion unlocks significantly broader design directions than a one-piece tub unit.
- Lower Utility Bills — Soaking in a tub uses roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders builds a tub to shower conversion, the structural components are built to last through years of daily use.
The Tub to Shower Conversion Process Step by Step
- Project Assessment and Design — A remodeling specialist meets with you on-site to evaluate your existing tub, plumbing, and bathroom layout. We discuss your must-haves and finish choices so the project plan reflects exactly what you want.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are taken out. Any plumbing connections tied to the old tub are professionally handled to set the stage for the revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is often the most technically demanding stage of a tub to shower conversion. New waterproof backer material is fastened to the wall studs, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The drain area is sloped correctly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new shower valve, drain body, and supply lines according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this stage.
- Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is finished and reviewed before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we hang your chosen enclosure system. Each component is secured correctly to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once all surfaces is complete, we conduct a careful final inspection. Each transition joint at corners and the floor-to-wall transition are caulked with mold-resistant silicone caulk. We show you the completed project and confirm everything meets your expectations.
