What Actually 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 drain assembly — is demolished and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom footprint, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's location.
On a structural level, the work involves capping the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then building out the new shower floor with a code-compliant slope toward the center drain. New moisture barrier is applied before any finish material goes on. Plumbing is rerouted to fit the new showerhead position and any additional fixtures you select.
The result is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall returns that square footage to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a barrier-free floor transition, support handles, and a built-in seat to assist homeowners with limited mobility.
- Quicker Showers — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you really live.
- Higher Resale Value — Updated bathrooms consistently rank among the top home improvements for resale. A tub to shower conversion communicates updated finishes to future owners.
- Simpler Upkeep — Shower floors and walls are often simpler to keep spotless than a standard bathtub with hard-to-reach corners.
- Personalized Finish Choices — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion unlocks many more design options than a prefab tub kit.
- Lower Utility Bills — Filling a bathtub requires roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can cut that to significantly less water per session.

The Tub to Shower Conversion Process Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist comes to your bathroom to evaluate your existing fixtures and framing. We discuss your must-haves and finish choices so the project plan reflects exactly what you want.
- Demolition and Removal — The existing tub unit and wall material are carefully removed. Existing water supply tied to the old tub are disconnected, capped, or rerouted to make room for the updated fixture configuration.
- Structural Prep and Moisture Barrier Installation — This is widely considered the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the wall studs, and a full waterproofing membrane is rolled or troweled on across the shower floor and lower walls. The drain area is pitched properly to ensure drainage.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew position the new plumbing fixtures according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this point.
- Finishing the Shower Walls and Floor — Skilled installers set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every tile edge is sealed and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we install your shower door or curtain hardware. Each component is set into the tile or framing to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we conduct a room-by-room final inspection. All caulk joints at corners and the floor-to-wall transition are sealed with flexible waterproof sealant. We review with you the final result and make sure everything looks and functions as planned.

However, if your home only has one bathroom, preserving a full bath somewhere in the home is worth discussing before scheduling demolition.

Our team at our firm will tell you plainly if a tub to shower conversion is not the right fit for your home.
