What Actually 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 plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's space.
On a mechanical level, the process involves capping the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower base with a proper slope toward the center drain. New waterproofing membrane is applied before any finish material goes in. Plumbing is rerouted to accommodate the new showerhead location and any additional fixtures you select.
The finished product is a code-compliant shower that performs reliably for decades. A tub to shower conversion done right is not just a cosmetic change — it is a thorough upgrade to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower restores that area to usable, accessible bathroom space.
- Improved Accessibility — A tub to shower conversion can incorporate a low-threshold or curbless entry, grab bars, and a shower bench to support aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — The majority of adults shower much more frequently than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Better Return on Investment — Updated bathrooms reliably appear among the most valued renovations 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 scrub and wipe down than a standard bathtub with hard-to-reach corners.
- Custom Design Options — From subway tile surrounds to frameless glass doors, a tub to shower conversion creates room for significantly broader design options than a one-piece tub unit.
- Reduced Water Use — Running a full bath consumes roughly 30 to 50 gallons of water per session. A water-efficient shower fixture installed during a tub to shower conversion can cut that to as little as 15 gallons.
- Long-Term Durability — When Brother & Brother Builders completes a tub to shower conversion, the underlying systems are built to last for decades.

New waterproof backer material is screwed to the wall studs, and a industry-standard moisture barrier is rolled or troweled on across every area that will contact water. The drain area is sloped correctly to prevent pooling.
