Let's get started to find out whether a tub to shower conversion is a smart choice for your space.
What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and hardware — is taken out and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's location.
On a mechanical level, the work involves capping the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the center drain. New waterproof liner is applied before any finish material goes up. Plumbing is adjusted to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The outcome is a structurally sound shower that functions properly for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a complete transformation to your bathroom's structure and usability.
Top Benefits of a Tub to Shower Conversion

- Better Mobility Access — A tub to shower conversion can feature a zero-entry design, grab bars, and a built-in seat to support homeowners with limited mobility.

- Higher Resale Value — Updated bathrooms always show up among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to future owners.
- Easier Cleaning — Shower floors and walls are often simpler to clean and maintain than a deep-soaking bathtub with grout lines on all four sides.
- Personalized Finish Choices — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion creates room for many more design directions than a prefab tub kit.
- Reduced Water Use — Filling a bathtub consumes roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.

The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A project consultant meets with you on-site to measure your existing tub, plumbing, and bathroom layout. We review your wishlist and timeline so the scope of work matches exactly what you need.
- Tub Extraction and Teardown — The existing fixtures and surrounding structure are demolished and cleared. Supply and drain lines tied to the old tub are professionally handled to prepare for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is arguably the most important stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a continuous waterproof layer is installed across all wet surfaces. The shower pan is pitched properly to ensure drainage.
- Installing New Shower Plumbing — Skilled tradespeople on our crew position the new plumbing fixtures according to your design plan. Whether you chose a standard showerhead or an upgraded fixture package, everything is installed at this stage.
- Finishing the Shower Walls and Floor — Tile setters apply your preferred wall and floor covering using professional-grade installation materials. Every tile edge is finished and inspected before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we hang your chosen enclosure system. Every mounting bracket is secured correctly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once all surfaces is finished and installed, we do a careful walk-through. Each transition joint at the perimeter are finished with professional-grade caulk. We show you the finished shower and confirm everything meets your expectations.
Who Is a Suitable Candidate for a Tub to Shower Conversion?
People who shower every day but almost never take a bath are typically ideal candidates a tub to shower conversion. This includes homeowners who struggle with high tub walls — a barrier-free shower conversion is one of the most impactful accessibility upgrades you can add to your bathroom. Parents of toddlers who previously needed the tub for baths may want to reconsider timing once the youngest family members are past the bathtub stage.

Getting rid of the old tub and replacing it with a right-sized walk-in shower can make a small bathroom feel significantly larger. However, if your home only has one bathroom, maintaining a soaking option is a conversation we always have with clients before scheduling demolition.
Candidates who benefit most from 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 polished, move-in-ready space. Our crew at Brother & Brother Builders will always be honest if a tub to shower conversion is not the best call for your particular situation.
