Considering a Tub to Shower Conversion? Here's What You Should Know
A well-planned tub to shower conversion can fundamentally transform how you use your bathroom every single day.

Whether you are downsizing or simply prefer a more modern shower setup, this overview walks you through all the details — from how the project works to what marks someone an great candidate. Keep reading to learn whether a tub to shower conversion is the best option for your bathroom.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is demolished and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's position.
On a technical level, the project involves disconnecting the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was here tied to it, then constructing the new shower pan with a proper slope toward the shower drain. New waterproof liner is applied before any tile, stone, or prefab panel goes up. Plumbing is modified to fit the new showerhead height and any extra spray features you add.
The result is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a complete transformation to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a walk-in shower frees up that room to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can include a low-threshold or curbless entry, safety rails, and a fold-down bench to support aging adults, people with disabilities, or anyone recovering from surgery.
- Faster Morning Routines — The majority of adults shower significantly more than they bathe. A tub to shower conversion matches your space with how you spend your time.
- Better Return on Investment — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to future owners.
- Lower Maintenance Demands — Shower pans, walls, and glass enclosures are often simpler to scrub and wipe down than a standard bathtub with a surrounding tile enclosure.
- Custom Design Options — From subway tile surrounds to frameless glass doors, a tub to shower conversion opens up far more design options than a standard tub surround.
- Water Efficiency — Soaking in a tub uses roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Structural Longevity — When our crew installs a tub to shower conversion, the underlying systems are built to last through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant comes to your bathroom to assess your existing tub, plumbing, and bathroom layout. We go over your wishlist and timeline so the project plan reflects exactly what you have in mind.
- Tub Extraction and Teardown — 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 revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a industry-standard moisture barrier is applied across every area that will contact water. The drain area is pitched properly to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew set the new rough-in plumbing according to your design plan. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this phase.
- Applying Your Chosen Finish Materials — Skilled installers set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every seam is grouted and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we mount your chosen enclosure system. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once everything is complete, we conduct a careful walk-through. Each transition joint at the base and wall corners are finished with professional-grade caulk. We review with you the finished shower and verify everything looks and functions as planned.
Who Is a Good 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 is especially relevant for homeowners who struggle with high tub walls — a curbless or low-threshold shower is among the most meaningful accessibility upgrades you can add to your bathroom. Parents of toddlers who previously needed the tub for bathing little ones may want to reconsider timing once the kids are shower-age.
A tub to shower conversion also is a smart move for people dealing with a cramped layout where the tub dominates the floor plan. Removing the tub and replacing it with a right-sized walk-in shower can open up the entire room. Keep in mind, if your property has no other tub, preserving a full bath somewhere in the home is something to weigh carefully before moving forward.
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 getting ready to list and wanting a fresh, buyer-ready bathroom. Our crew at Brother & Brother Builders will tell you plainly if a tub to shower conversion is not the right fit for your particular situation.
