Considering a Tub to Shower Conversion? Here's What You Should Know
A thoughtfully designed tub to shower conversion can completely change how you use your bathroom every single morning.

Whether you are updating an outdated space or simply prefer a more accessible shower setup, this article walks you through all the details — from how the project works to what makes someone an ideal candidate. Let's get started to learn whether a tub to shower conversion is the right move for your space.
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 hardware — is taken out and replaced with a professionally installed shower unit. The scope 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 space.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, removing the tub shell and any surrounding wall material that was tied to it, then framing the new shower base with a proper slope toward the shower drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes up. Plumbing is adjusted to fit the new showerhead location and any extra spray features you add.
The finished product is a code-compliant 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 plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs occupy between 13 and 16 square feet. Converting to a custom shower stall frees up that square footage to usable, accessible bathroom space.

- Faster Morning Routines — 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 reliably appear among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Lower Maintenance Demands — Shower surrounds and bases are often simpler to scrub and wipe down than a deep-soaking bathtub with a surrounding tile enclosure.
- Tailored Aesthetic Selections — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up many more design directions than a one-piece tub unit.
- Lower Utility Bills — Running a full bath requires roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- Structural Longevity — When our team completes a tub to shower conversion, the underlying systems are constructed to hold up for decades.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist comes to your bathroom to evaluate your existing fixtures and framing. We review your goals, design preferences, and budget so the project plan reflects exactly what you want.
- 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 set the stage for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is often the most important stage of a tub to shower conversion. New moisture-resistant substrate is attached to the framing, and a full waterproofing membrane is rolled or troweled on across all wet surfaces. The floor base is sloped correctly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew position the new rough-in plumbing according to your chosen layout. Whether you went with a standard showerhead or an upgraded fixture package, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — Our finish crew install your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is sealed and checked before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your design choice, we hang your shower door or curtain hardware. Each component is anchored properly to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once all surfaces is finished and installed, we do a careful final inspection. All caulk joints at corners and the floor-to-wall transition are sealed with flexible waterproof sealant. We walk you through the finished shower and verify everything meets your expectations.
