Whether you are updating an outdated space or simply want a more modern shower setup, this overview walks you through all the details — from how the conversion works to what qualifies someone an ideal candidate. Read on to see whether a tub to shower conversion is the best option for your bathroom.
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 demolished and replaced with a purpose-built shower unit. The scope of the project depends on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a structural level, the work involves disconnecting the existing tub drain and supply lines, removing the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a correct slope toward the drain. New waterproof liner is installed before any surface covering goes up. Plumbing is adjusted to serve the new showerhead height and any body sprays, handheld wands, or rain heads you add.
The outcome is a structurally sound shower that drains correctly for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete transformation to your bathroom's infrastructure and finish.
Major 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 frees up that room to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a low-threshold or curbless entry, support handles, and a shower bench to assist those who need a safer bathing solution.
- Faster Morning Routines — Most people shower significantly more 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.
- Simpler Upkeep — Shower floors and walls are generally easier to clean and maintain than a deep-soaking bathtub with grout lines on all four sides.
- Custom Design Options — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion creates room for significantly broader design options than a one-piece tub unit.
- Water Efficiency — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders completes a tub to shower conversion, the structural components are designed for durability well beyond 20 years.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A member of our team meets with you on-site to assess your existing tub, plumbing, and bathroom layout. We discuss your must-haves and finish choices so the project plan aligns with exactly what you have in mind.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Supply and drain lines tied to the old tub are properly shut off to set the stage for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most important stage of a tub to shower conversion. New waterproof backer material is attached to the structural framing, and a continuous waterproof layer is applied across the shower floor and lower walls. The shower pan is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new rough-in plumbing according to your design plan. Whether you selected a basic or premium shower setup, everything is installed at this point.
- Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every grout joint is sealed and checked before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we hang your chosen enclosure system. All hardware is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is tiled, grouted, and enclosed, we do a thorough quality review. All caulk joints at the base and wall corners are finished with mold-resistant silicone caulk. We walk you through the finished shower and verify everything meets your expectations.
Who Is a Strong Candidate for a Tub to Shower Conversion?

This also applies to aging adults or people with mobility limitations — a curbless or low-threshold shower is among the most meaningful check here accessibility changes you can add to your bathroom. Parents of toddlers who previously needed the tub for bathing little ones may also benefit once the kids are past the bathtub stage.

Our experts at our firm will always be honest if a tub to shower conversion is not in your best interest for your home.
