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 structural upgrade service in which an existing bathtub — along with its surround and plumbing fixtures — is taken out and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's location.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a code-compliant slope toward the drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes on. Plumbing is adjusted to serve the new showerhead height and any extra spray features you choose.
The result is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a visual change — it is a fundamental upgrade to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower returns that room to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can include a zero-entry design, grab bars, and a shower bench to assist those who need a safer bathing solution.
- Quicker Showers — The majority of adults shower far more often than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Lower Maintenance Demands — Shower pans, walls, and glass enclosures are often simpler to keep spotless than a standard bathtub with a surrounding tile enclosure.
- Tailored Aesthetic Selections — From natural stone slabs to frameless glass doors, a tub to shower conversion creates room for far more design options than a one-piece tub unit.
- Water Efficiency — Running a full bath requires roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Lasting Construction — When Brother & Brother Builders builds a tub to shower conversion, the structural components are built to last well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A remodeling specialist comes to your bathroom to assess your existing tub, plumbing, and bathroom layout. We discuss your goals, design preferences, and budget so the proposal aligns with exactly what you want.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to set the stage for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a full waterproofing membrane is installed across the shower floor and lower walls. The shower pan is sloped correctly to avoid standing water.
- Installing New Shower Plumbing — Skilled tradespeople on our crew install the new shower valve, drain body, and supply lines according to your fixture selections. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this stage.
- 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 tile edge is sealed and reviewed before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is anchored properly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once the full shower is tiled, grouted, and enclosed, we conduct a thorough final inspection. Every seam at the base and wall corners are caulked with flexible waterproof sealant. We show you the finished shower and verify everything is exactly what you wanted.
Who Is a Suitable Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are usually perfect for a tub to shower conversion. This includes homeowners who struggle with high tub walls — a curbless or low-threshold shower is one of the most impactful accessibility changes you can invest in for your bathroom. Families with young children who previously needed the tub for baths may want to reconsider timing once those children are shower-age.
