What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is taken out and replaced with a professionally installed shower unit. The scale of the project varies based on your existing bathroom layout, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, lifting the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a correct slope toward the drain. New waterproofing membrane is installed before any finish material goes up. Plumbing is rerouted to serve the new showerhead height and any additional fixtures you add.
The outcome is a fully waterproofed shower that performs reliably 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 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 restores that room to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can feature a low-threshold or curbless entry, support handles, and a built-in seat to support those who need a safer bathing solution.
- More Efficient Daily Bathing — 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 reliably appear among the top home improvements for resale. A tub to shower conversion tells buyers the home has been maintained to prospective buyers.
- Easier Cleaning — Shower floors and walls are generally easier to keep spotless than a standard bathtub with hard-to-reach corners.
- Custom Design Options — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion creates room for far more design possibilities than a standard tub surround.
- Lower Utility Bills — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Long-Term Durability — When our crew installs a tub to shower conversion, the structural components are built to last for decades.
The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A member of our team comes to your bathroom to measure your existing space and infrastructure. We discuss your goals, design preferences, and budget so the scope of work reflects exactly what you need.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to make room for the updated fixture configuration.
- Structural Prep and Moisture Barrier Installation — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a full waterproofing membrane is applied across every area that will contact water. The drain area is graded toward the drain to avoid standing water.
- 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 chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this point.
- Tile, Stone, or Panel Installation — Tile setters apply your selected finish material using the correct adhesive and grout system. Every grout joint is sealed and reviewed before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we install your chosen enclosure system. All hardware is secured correctly to prevent loosening over time.
- Completion Walk-Through and Finishing Touches — Once the full shower is tiled, grouted, and enclosed, we do a thorough walk-through. Each transition joint at corners and the floor-to-wall transition are finished with flexible waterproof sealant. We walk you through the final result and confirm everything is exactly what you wanted.
