Let's get started to learn whether a tub to shower conversion is a smart choice for your bathroom.
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 framing and hardware — is taken out and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom layout, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's location.
On a technical level, the process involves capping the existing tub drain and supply lines, removing the tub shell and any surrounding wall material that was tied to it, then building out the new shower pan with a proper slope toward the center drain. New waterproofing membrane is applied before any surface covering goes in. Plumbing is rerouted to serve the new showerhead position and any additional fixtures you select.
The outcome is a structurally sound shower that performs reliably for the long term. A tub to shower conversion done right is not just a cosmetic change — it is a thorough upgrade to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a curbless shower restores that area to usable, accessible bathroom space.
- Better Mobility Access — A tub to shower conversion can include a low-threshold or curbless entry, safety rails, and a fold-down bench to support those who need a safer bathing solution.
- More Efficient Daily Bathing — Most people shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Better Return on Investment — Updated bathrooms reliably appear among the top home improvements for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Lower Maintenance Demands — Shower floors and walls are typically faster to scrub and wipe down than a full-length bathtub with hard-to-reach corners.
- Custom Design Options — From subway tile surrounds to semi-frameless enclosures, a tub to shower conversion creates room for many more design possibilities than a prefab tub kit.
- Reduced Water Use — Running a full bath requires roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can cut that to under 20 gallons per shower.
- Long-Term Durability — When our crew installs a tub to shower conversion, the waterproofing, substrate, and finish materials are built to last through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant visits your home to assess your existing tub, plumbing, and bathroom layout. We go over your wishlist and timeline so the proposal aligns with exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are taken out. Existing water supply tied to the old tub are disconnected, capped, or rerouted to make room for the revised drain placement.
- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New moisture-resistant substrate is attached to the framing, and a industry-standard moisture barrier is applied across every area that will contact water. The shower pan is pitched properly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your fixture selections. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Our finish crew apply your selected finish material using professional-grade installation materials. Every seam is finished and reviewed before moving to the next phase.
- Installing the Shower Enclosure — Depending on your preference, we mount your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is anchored properly to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we conduct a careful quality review. Every seam at the base and wall corners are caulked with professional-grade caulk. We review with you the completed project and make sure everything is exactly what you wanted.
