What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom layout, your style choices, and whether you plan to expand the shower's usable area beyond the original tub's space.
On a structural level, the process involves capping the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a code-compliant slope toward the shower drain. New waterproof liner is installed before any finish material goes up. Plumbing is rerouted to fit the new showerhead position and any extra spray features you choose.
The result is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done right is not just a surface-level change — it is a thorough upgrade to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower frees up that room to usable, accessible bathroom space.
- Better Mobility Access — A tub to shower conversion can feature a low-threshold or curbless entry, grab bars, and a built-in seat to assist those who need a safer bathing solution.
- Quicker Showers — Most people shower much more frequently than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Stronger Home Appraisals — Updated bathrooms reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Easier Cleaning — Shower floors and walls are generally easier to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From subway tile surrounds to frameless glass doors, a tub to shower conversion opens up far more design options than a standard tub surround.
- Lower Utility Bills — 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 cut that to significantly less water per session.
- Long-Term Durability — When our team completes a tub to shower conversion, the waterproofing, substrate, and finish materials are built to last for decades.
The Tub to Shower Conversion Project Step by Step

- Structural Prep and Moisture Barrier Installation — This is arguably the most important stage of a tub to shower conversion. New cement board or tile backer is fastened to the framing, and a continuous waterproof layer is installed across the shower floor and lower walls. The shower pan is sloped correctly to avoid standing water.
- Installing New Shower Plumbing — Our plumbing team set the new plumbing fixtures according to your chosen layout. Whether you chose a standard showerhead or an upgraded fixture package, everything is roughed in at this stage.
- Applying Your Chosen Finish Materials — Tile setters apply your selected finish material using professional-grade installation materials. Every tile edge is sealed and inspected before moving to the next phase.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we mount 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 the full shower is complete, we do a careful quality review. Every seam at the base and wall corners are caulked with mold-resistant silicone caulk. We walk you through the completed project and make sure everything meets your expectations.
