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 enclosure and drain assembly — is demolished and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a structural level, the project involves capping the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then building out the new shower base with a proper slope toward the center drain. New waterproof liner is laid down before any surface covering goes up. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you add.
The result is a structurally sound shower that drains correctly for the long term. A tub to shower conversion done right is not just a visual change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs consume between 13 and 16 square feet. Converting to a curbless shower restores that room to usable, open bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a barrier-free floor transition, grab bars, and a shower bench to support homeowners with limited mobility.
- Quicker Showers — A large portion of homeowners shower much more frequently 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.
- Simpler Upkeep — Shower surrounds and bases are typically faster to clean and maintain than a deep-soaking bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From subway tile surrounds to frameless glass doors, a tub to shower conversion creates room for significantly broader design directions than a standard tub surround.
- Reduced Water Use — Filling a bathtub uses roughly 30 to 50 gallons of water per session. A water-efficient shower fixture installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Lasting Construction — When our team installs a tub to shower conversion, the underlying systems are designed for durability well beyond 20 years.
The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A remodeling specialist comes to your bathroom to evaluate your existing space and infrastructure. We go over your wishlist and timeline so the scope of work aligns with exactly what you need.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Existing water supply tied to the old tub are properly shut off to make room for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is often the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is attached to the wall studs, and a industry-standard moisture barrier is installed across the shower floor and lower walls. The shower pan is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew position the new rough-in plumbing according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this stage.
- Tile, Stone, or Panel Installation — Our finish crew apply your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every seam is sealed and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your selected style, we mount your shower door or curtain hardware. Every mounting bracket is anchored properly to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once everything is finished and installed, we conduct a room-by-room final inspection. All caulk joints at the base and wall corners are finished with flexible waterproof sealant. We show you the final result and verify everything meets your expectations.
Who Is a Good Candidate for a Tub to Shower Conversion?

Our experts at our firm will always be honest if a tub to shower conversion is not the best call for your home.
