Ready for a Tub to Shower Conversion? Here's What You Should Know
A thoughtfully designed tub to shower conversion can fundamentally transform how you use your bathroom every single morning.

A tub to shower conversion swaps out that underused tub with a functional walk-in shower that fits the way you actually move through your home.

A tub to shower conversion is among our most popular services we offer, and for clear purposes — it delivers real, lasting improvement without a total demolition project.
Whether you are downsizing or simply prefer a more efficient shower setup, this guide walks you through all the details — from how the process works to what marks someone an perfect candidate. Let's get started to see whether a tub to shower conversion is a smart choice for your space.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and drain assembly — is demolished and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom footprint, your finish selections, and whether you want to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the project involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any old tile surround that was tied to it, read more then building out the new shower base with a code-compliant slope toward the shower drain. New waterproof liner is installed before any tile, stone, or prefab panel goes up. Plumbing is modified to fit the new showerhead position and any additional fixtures you select.
The outcome is a code-compliant shower that functions properly for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough improvement to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a custom shower stall restores that room to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can include a low-threshold or curbless entry, grab bars, and a shower bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to future owners.
- Simpler Upkeep — Shower surrounds and bases are typically faster to keep spotless than a standard bathtub with a surrounding tile enclosure.
- Tailored Aesthetic Selections — From subway tile surrounds to frameless glass doors, a tub to shower conversion unlocks many more design options than a standard tub surround.
- Water Efficiency — Soaking in a tub consumes roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can lower usage to significantly less water per session.
- Long-Term Durability — When our team builds a tub to shower conversion, the underlying systems are designed for durability well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A member of our team meets with you on-site to measure your existing space and infrastructure. We review your must-haves and finish choices so the scope of work reflects exactly what you want.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to prepare for the new shower plumbing layout.
- Building the Shower's Foundation — This is widely considered the most technically demanding stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a industry-standard moisture barrier is installed across every area that will contact water. The shower pan is pitched properly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew install the new rough-in plumbing according to your fixture selections. Whether you selected a standard showerhead or an upgraded fixture package, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every seam is grouted and reviewed before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your design choice, we hang your shower door or curtain hardware. All hardware is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once everything is complete, we perform a thorough final inspection. All caulk joints at corners and the floor-to-wall transition are finished with flexible waterproof sealant. We review with you the completed project and verify everything looks and functions as planned.
Who Is a Strong Candidate for a Tub to Shower Conversion?
People who shower every day but almost never take a bath are usually perfect for a tub to shower conversion. This also applies to homeowners who struggle with high tub walls — a curbless or low-threshold shower is among the most meaningful accessibility modifications you can add to your bathroom. Parents of toddlers who previously needed the tub for young children's hygiene routines may want to reconsider timing once the youngest family members are past the bathtub stage.
A tub to shower conversion also works well for homeowners in smaller bathrooms where the tub monopolizes the available area. Removing the tub and putting in a custom shower can dramatically improve the sense of space. Keep in mind, if your home only has one bathroom, preserving a full bath somewhere in the home is a conversation we always have with clients before committing.
Homeowners who get the most out of a tub to shower conversion are those planning to stay in the home long-term as well as those preparing to sell and needing a bathroom that reads modern and updated. Our experts at Brother & Brother Builders will give you a straight answer if a tub to shower conversion is not the best call for your particular situation.
