What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your design preferences, and whether you plan to expand the shower's square footage beyond the original tub's space.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then constructing the new shower base with a correct slope toward the drain. New waterproofing membrane is installed before any surface covering goes in. Plumbing is rerouted to fit the new showerhead position and any extra spray features you select.
The finished product is a structurally sound shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a fundamental improvement to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a custom shower stall restores that square footage to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a zero-entry design, safety rails, and a built-in seat to support homeowners with limited mobility.
- More Efficient Daily Bathing — Most people shower significantly more than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Higher Resale Value — Updated bathrooms always show up among the most valued renovations for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Simpler Upkeep — Shower pans, walls, and glass enclosures are often simpler to scrub and wipe down than a deep-soaking bathtub with hard-to-reach corners.
- Tailored Aesthetic Selections — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion unlocks many more design possibilities than a prefab tub kit.
- Reduced Water Use — Running a full bath uses roughly 30 to 50 gallons of water per bath. A water-efficient shower fixture installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Lasting Construction — When our team installs a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A member of our team visits your home to evaluate your existing fixtures and framing. We discuss your must-haves and finish choices so the scope of work matches exactly what you have in mind.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Existing water supply tied to the old tub are disconnected, capped, or rerouted to make room for the new shower plumbing layout.
- Building the Shower's Foundation — This is widely considered the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the wall studs, and a continuous waterproof layer is applied across the shower floor and lower walls. The shower pan is pitched properly to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced 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.
- Applying Your Chosen Finish Materials — Our finish crew set your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every grout joint is grouted and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we mount your shower door or curtain hardware. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once everything is complete, we conduct a room-by-room quality review. All caulk joints at corners and the floor-to-wall transition are sealed with mold-resistant silicone caulk. We review with you the completed project and confirm everything looks and functions as planned.

Our team at our firm will always be honest if a tub to shower conversion is not the right fit for your specific layout.
