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 enclosure and hardware — is removed and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom footprint, your style choices, and whether you need to expand the shower's square footage beyond the original tub's position.
On a mechanical level, the process involves capping the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower pan with a correct slope toward the center drain. New waterproofing membrane is installed before any finish material goes up. Plumbing is rerouted to fit the new showerhead position and any extra spray features you select.
The result is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
Major 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 curbless shower frees up that square footage to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can incorporate a barrier-free floor transition, safety rails, and a shower bench to assist aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — Most people shower far more often than they bathe. A tub to shower conversion matches your space with how you spend your time.
- Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Simpler Upkeep — Shower floors and walls are typically faster to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion creates room for far more design possibilities than a standard tub surround.
- Reduced Water Use — Running a full bath requires roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Long-Term Durability — When our crew completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability for decades.
The Tub to Shower Conversion Project Step by Step
- Initial Consultation and Planning — A member of our team visits your home to assess your existing tub, plumbing, and bathroom layout. We discuss your wishlist and timeline so the project plan reflects exactly what you have in mind.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.
- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New waterproof backer material is fastened to the wall studs, and a industry-standard moisture barrier is applied across the shower floor and lower walls. The drain area is graded toward the drain to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new shower valve, drain body, and supply lines according to your fixture selections. Whether you selected a standard showerhead or an upgraded fixture package, everything is positioned at this phase.
- Tile, Stone, or Panel Installation — Skilled installers install your selected finish material using appropriate mortar, grout, and setting materials. Every tile edge is finished and reviewed before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your shower door or curtain hardware. Every mounting bracket is secured correctly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once the full shower is complete, we conduct a room-by-room quality review. Each transition joint at the base and wall corners are finished with flexible waterproof sealant. We show you the completed project and make sure everything is exactly what you wanted.
