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 drain assembly — is demolished and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom layout, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's location.
On a structural level, the process involves disconnecting the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then constructing the new shower base with a proper slope toward the drain. New waterproofing membrane is installed before any finish material goes up. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you select.
The outcome is a fully waterproofed shower that drains correctly for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a complete transformation to your bathroom's structure and usability.
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 curbless shower returns that square footage to usable, navigable bathroom space.

- Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to future owners.
- Simpler Upkeep — Shower surrounds and bases are typically faster to scrub and wipe down than a deep-soaking bathtub with hard-to-reach corners.
- Custom Design Options — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up many more design options than a one-piece tub unit.

The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist comes to your bathroom to measure your existing tub, plumbing, and bathroom layout. We review your goals, design preferences, and budget so the proposal matches exactly what you have in mind.
- Tub Extraction and Teardown — The existing tub unit and wall material are carefully removed. Supply and drain lines tied to the old tub are properly shut off to make room for the new shower plumbing layout.
- Building the Shower's Foundation — This is arguably the most important stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a industry-standard moisture barrier is rolled or troweled on across the shower floor and lower walls. The drain area is sloped correctly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Our plumbing team position the new shower valve, drain body, and supply lines 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 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 grout joint is finished and reviewed before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we hang your shower door or curtain hardware. All hardware is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once all surfaces is tiled, grouted, and enclosed, we perform a thorough final inspection. Every seam at corners and the floor-to-wall transition are caulked with professional-grade caulk. We review with you the finished shower and confirm everything looks and functions as planned.
