Read on to learn whether a tub to shower conversion is a smart choice for your space.
What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and drain assembly — is demolished and replaced with a purpose-built 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 technical level, the project involves rerouting the existing tub drain and supply lines, removing the tub unit and any surrounding wall material that was tied to it, then framing the new shower pan with a proper slope toward the drain. New waterproof liner is applied before any tile, stone, or prefab panel goes up. Plumbing is modified to accommodate the new showerhead location and any additional fixtures you add.
The outcome is a structurally sound shower that functions properly for decades. A tub to shower conversion done right is not just a surface-level change — it is a fundamental improvement to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower returns that square footage to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can include a zero-entry design, support handles, and a shower bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Better Return on Investment — Updated bathrooms always show up among the top home improvements for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Easier Cleaning — Shower pans, walls, and glass enclosures are generally easier to clean and maintain than a full-length bathtub with hard-to-reach corners.
- Personalized Finish Choices — From natural stone slabs to frameless glass doors, a tub to shower conversion creates room for far more design options than a standard tub surround.
- Water Efficiency — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Long-Term Durability — When our team installs a tub to shower conversion, the structural components are designed for durability well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A project consultant visits your home to evaluate your existing fixtures and framing. We discuss your must-haves and finish choices so the project plan reflects exactly what you want.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are taken out. Supply and drain lines tied to the old tub are properly shut off to prepare for the revised drain placement.
- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a continuous waterproof layer is applied across the shower floor and lower walls. The floor base is graded toward the drain to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew set the new shower valve, drain body, and supply lines according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is roughed in at this phase.
- Tile, Stone, or Panel Installation — Skilled installers apply your selected finish material using professional-grade installation materials. Every grout joint is finished and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your selected style, we mount your shower door or curtain hardware. All hardware is secured correctly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once the full shower is tiled, grouted, and enclosed, we conduct a room-by-room quality review. Every seam at corners and the floor-to-wall transition are caulked with professional-grade caulk. We walk you through the completed project and confirm everything looks and functions as planned.
Who Is a Good Candidate for a Tub to Shower Conversion?

That said, if your property has no other tub, keeping at least one bathtub is worth discussing before moving forward.
