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 enclosure and hardware — is demolished and replaced with a purpose-built shower unit. The scope of the project is shaped by your existing bathroom footprint, your finish selections, and whether you want to expand the shower's usable area beyond the original tub's space.
On a structural level, the project involves capping the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then framing the new shower floor with a proper slope toward the center drain. New waterproofing membrane is applied before any finish material goes on. Plumbing is rerouted to accommodate the new showerhead height and any additional fixtures you add.
The result is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a complete transformation to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs consume between 13 and 16 square feet. Converting to a walk-in shower restores that area to usable, open bathroom space.
- Improved Accessibility — A tub to shower conversion can include a zero-entry design, grab bars, and a built-in seat to assist those who need a safer bathing solution.
- Faster Morning Routines — The majority of adults shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Stronger Home Appraisals — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to future owners.
- Simpler Upkeep — Shower surrounds and bases are typically faster to clean and maintain than a standard bathtub with hard-to-reach corners.
- Personalized Finish Choices — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion opens up far more design directions than a one-piece tub unit.
- Lower Utility Bills — Soaking in a tub requires roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can cut that to significantly less water per session.
- Lasting Construction — When Brother & Brother Builders builds a tub to shower conversion, the structural components are constructed to hold up for decades.
The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A project consultant meets with you on-site to assess your existing fixtures and framing. We discuss your goals, design preferences, and budget so the project plan matches exactly what you want.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Supply and drain lines tied to the old tub are properly shut off to make room for the revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is attached to the wall studs, and a full waterproofing membrane is applied across all wet surfaces. The shower pan is sloped correctly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Our plumbing team set the new shower valve, drain body, and supply lines according to your design plan. Whether you chose a basic or premium shower setup, everything is installed at this phase.
- Finishing the Shower Walls and Floor — Tile setters apply your preferred wall and floor covering using the correct adhesive and grout system. Every seam is finished and checked before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we mount your shower door or curtain hardware. All hardware is secured correctly to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once everything is finished and installed, we conduct a thorough walk-through. Every seam at the base and wall corners are caulked with professional-grade caulk. We review with you the final result and make sure everything is exactly what you wanted.
