What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and drain assembly — is removed and replaced with a professionally installed shower unit. The scale of the project is shaped by your existing bathroom footprint, your finish selections, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the work involves capping the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then constructing the new shower pan with a code-compliant slope toward the center drain. New moisture barrier is installed before any tile, stone, or prefab panel goes in. Plumbing is rerouted to fit the new showerhead height and any extra spray features you select.
The result is a code-compliant shower that drains correctly for many years. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete transformation to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall restores that square footage to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can include a low-threshold or curbless entry, safety rails, and a fold-down bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — The majority of adults shower much more frequently than they bathe. A tub to shower conversion redesigns your layout 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 tells buyers the home has been maintained to prospective buyers.
- Easier Cleaning — Shower surrounds and bases are often simpler to keep spotless than a full-length bathtub with hard-to-reach corners.
- Custom Design Options — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up significantly broader design possibilities than a one-piece tub unit.

The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A project consultant visits your home to evaluate your existing space and infrastructure. We discuss your must-haves and finish choices so the project plan matches exactly what you want.

- Structural Prep and Moisture Barrier Installation — This is arguably the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is attached to the structural framing, and a continuous waterproof layer is applied across the shower floor and lower walls. The shower pan is sloped correctly to ensure drainage.

- Applying Your Chosen Finish Materials — Our finish crew apply your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every grout joint is finished and inspected before moving to the next phase.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we install your shower door or curtain hardware. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.

Each transition joint at the perimeter are sealed with professional-grade caulk. We walk you through the completed project and make sure everything meets your expectations.
