Thinking About a Tub to Shower Conversion? Read This First
A thoughtfully designed tub to shower conversion can fundamentally transform how you use your bathroom every single morning.

Whether you are downsizing or simply need a more modern shower setup, this overview walks you through all the details — from how the project works to what marks someone an perfect candidate. Let's get started to learn whether a tub to shower conversion is the best option 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 surround and drain assembly — is taken out and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's location.
On a structural level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a correct slope toward the center drain. New waterproofing membrane is installed before any surface covering goes up. Plumbing is adjusted to accommodate the new showerhead location and any additional fixtures you add.
The outcome is a structurally sound shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a complete upgrade to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall frees up that room to usable, accessible bathroom space.
- Improved Accessibility — A tub to shower conversion can include a barrier-free floor transition, grab bars, and a fold-down bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Better Return on Investment — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to real estate agents.
- Simpler Upkeep — Shower surrounds and bases are typically faster to clean and maintain than a deep-soaking bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From natural stone slabs to semi-frameless enclosures, a tub to shower conversion unlocks many more design options than a one-piece tub unit.
- Water Efficiency — Filling a bathtub uses roughly 30 to 50 gallons of water per bath. A modern shower valve installed during a tub to shower conversion can cut that to significantly less water per session.
- Long-Term Durability — When Brother & Brother Builders builds a tub to shower conversion, the structural components are built to last well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to measure your existing fixtures and framing. We review your must-haves and finish choices so the proposal aligns with exactly what you need.
- Tub Extraction and Teardown — 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 new shower plumbing layout.
- Building the Shower's Foundation — This is often the most critical stage of a tub to shower conversion. New waterproof backer material is attached to the wall studs, and a full waterproofing membrane is installed across the shower floor and lower walls. The shower pan is sloped correctly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your design plan. Whether you went with a basic or premium shower setup, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Our finish crew apply your selected finish material using appropriate mortar, grout, and setting materials. Every grout joint is finished and inspected before moving to the next phase.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we install your shower door or curtain hardware. All hardware is secured correctly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is finished and installed, we do a room-by-room walk-through. All caulk joints at corners and the floor-to-wall transition are finished with mold-resistant silicone caulk. We show you the completed project and make sure everything meets your expectations.
