Let's get started to find out whether a tub to shower conversion is a smart choice for your space.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and hardware — is demolished and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom layout, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's position.
On a structural level, the work 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 installed before any finish material goes in. Plumbing is adjusted to fit the new showerhead location and any extra spray features you select.
The result is a fully waterproofed shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower frees up that area to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can include a low-threshold or curbless entry, safety rails, and a built-in seat to accommodate those who need a safer bathing solution.
- Quicker Showers — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion redesigns your layout with how you really live.
- Better Return on Investment — Updated bathrooms consistently rank among the top home improvements for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Easier Cleaning — Shower surrounds and bases are typically faster to keep spotless than a full-length bathtub with a surrounding tile enclosure.
- Custom Design Options — From natural stone slabs to frameless glass doors, a tub to shower conversion unlocks many more design possibilities than a prefab tub kit.
- Lower Utility Bills — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Structural Longevity — When our crew installs a tub to shower conversion, the underlying systems are constructed to hold up well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A project consultant comes to your bathroom to evaluate your existing tub, plumbing, and bathroom layout. We go over your wishlist and timeline so the proposal matches exactly what you need.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Supply and drain lines tied to the old tub are properly shut off to set the stage for the updated fixture configuration.
- Building the Shower's Foundation — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the structural framing, and a industry-standard moisture barrier is applied across every area that will contact water. The shower pan is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new rough-in plumbing according to your design plan. Whether you went with a standard showerhead or an upgraded fixture package, everything is roughed in at this point.
- Finishing the Shower Walls and Floor — Our finish crew install your preferred wall and floor covering using the correct adhesive and grout system. Every tile edge is finished and inspected before moving to the next phase.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we install your chosen enclosure system. Each component is anchored properly to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once everything is tiled, grouted, and enclosed, we perform a thorough final inspection. Each transition joint at corners and the floor-to-wall transition are sealed with mold-resistant silicone caulk. We review with you the completed project and verify everything is exactly what you wanted.
