Keep reading to find out whether a tub to shower conversion is the right move for your space.
What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and hardware — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom layout, your style choices, and whether you need to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, taking out 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 drain. New moisture barrier is laid down before any surface covering goes up. Plumbing is adjusted to fit the new showerhead location and any extra spray features you choose.
The outcome is a structurally sound shower that functions properly for the long term. A tub to shower conversion done right is not just a cosmetic change — it is a thorough improvement to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower restores that area to usable, open bathroom space.
- Better Mobility Access — A tub to shower conversion can include a zero-entry design, safety rails, and a fold-down bench to assist those who need a safer bathing solution.
- Quicker Showers — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion matches your space with how you spend your time.
- Stronger Home Appraisals — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to future owners.
- Simpler Upkeep — Shower surrounds and bases are generally easier to clean and maintain than a full-length bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From natural stone slabs to semi-frameless enclosures, a tub to shower conversion creates room for significantly broader design possibilities than a prefab tub kit.
- Water Efficiency — Running a full bath uses 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.
- Lasting Construction — When Brother & Brother Builders completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability well beyond 20 years.
The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A project consultant meets with you on-site to evaluate your existing space and infrastructure. We review your wishlist and timeline so the project plan matches exactly what you need.
- Demolition and Removal — 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 disconnected, capped, or rerouted to prepare for the revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most technically demanding stage of a tub to shower conversion. New waterproof backer material is attached to the framing, and a full waterproofing membrane is installed across every area that will contact water. The floor base is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new rough-in plumbing according to your design plan. Whether you chose a basic or premium shower setup, everything is positioned at this stage.
- Finishing the Shower Walls and Floor — Tile setters set your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every grout joint is finished and inspected before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we install your chosen enclosure system. Every mounting bracket is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once everything is finished and installed, we conduct a thorough quality review. Each transition joint at the perimeter are sealed with professional-grade caulk. We walk you through the completed project and verify everything is exactly what you wanted.
Who Is a Suitable Candidate for a Tub to Shower Conversion?
Homeowners who rarely or never use their bathtub are usually perfect for a tub to shower conversion. This includes homeowners who struggle with high tub walls — a barrier-free shower conversion is one of the most impactful accessibility modifications you can add to your bathroom.

Our crew at our firm will give you a straight answer if a tub to shower conversion is not the right fit for your home.
