Whether you are aging in place or simply prefer a more efficient shower setup, this overview walks you through the full picture — from how the process works to what qualifies someone an perfect candidate. Let's get started to learn whether a tub to shower conversion is the best option for your space.
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 drain assembly — is removed and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the work involves rerouting 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 constructing the new shower floor with a code-compliant slope toward the center drain. New moisture barrier is installed before any finish material goes on. Plumbing is adjusted to fit the new showerhead height and any extra spray features you choose.
The outcome is a code-compliant shower that functions properly for decades. A tub to shower conversion done correctly is not just a visual change — it is a complete improvement to your bathroom's structure and usability.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall returns that room to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can incorporate a low-threshold or curbless entry, support handles, and a shower bench to assist those who need a safer bathing solution.
- More Efficient Daily Bathing — The majority of adults shower far more often than they bathe. A tub to shower conversion matches your space with how you spend your time.
- Higher Resale Value — Updated bathrooms always show up among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Lower Maintenance Demands — Shower surrounds and bases are generally easier to keep spotless than a deep-soaking bathtub with hard-to-reach corners.
- Custom Design Options — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion opens up far more design possibilities than a one-piece tub unit.
- Lower Utility Bills — Soaking in a tub requires roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can cut that to as little as 15 gallons.
- Long-Term Durability — When Brother & Brother Builders installs a tub to shower conversion, the underlying systems are constructed to hold up for decades.

- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New cement board or tile backer is attached to the framing, and a industry-standard moisture barrier is rolled or troweled on across every area that will contact water. The floor base is graded toward the drain to prevent pooling.

Each transition joint at the perimeter are sealed with mold-resistant silicone caulk. We show you the final result and verify everything looks and functions as planned.
