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 hardware — is removed and replaced with a custom-fitted shower unit. The scope of the project is shaped by your existing bathroom footprint, your design preferences, and whether you want to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the work involves website capping the existing tub drain and supply lines, removing the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a code-compliant slope toward the center drain. New waterproof liner is applied before any tile, stone, or prefab panel goes up. Plumbing is rerouted to fit the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The result is a structurally sound shower that drains correctly for decades. A tub to shower conversion done right is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion

- Faster Morning Routines — Most people shower far more often than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Stronger Home Appraisals — Updated bathrooms always show up among the top home improvements for resale. A tub to shower conversion communicates updated finishes to future owners.
- Easier Cleaning — Shower pans, walls, and glass enclosures are typically faster to keep spotless than a standard 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 significantly broader design directions than a one-piece tub unit.
- Reduced Water Use — Soaking in a tub requires roughly 30 to 50 gallons of water per bath. A modern shower valve installed during a tub to shower conversion can reduce consumption to as little as 15 gallons.
- Lasting Construction — When our crew completes a tub to shower conversion, the underlying systems are constructed to hold up well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A member of our team comes to your bathroom to measure your existing fixtures and framing. We discuss your must-haves and finish choices so the scope of work reflects exactly what you have in mind.
- Demolition and Removal — The existing tub unit and wall material are taken out. Existing water supply tied to the old tub are professionally handled to prepare for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the framing, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The drain area is pitched properly to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your design plan. Whether you went with a standard showerhead or an upgraded fixture package, everything is installed at this stage.
- Finishing the Shower Walls and Floor — Tile setters set your selected finish material using the correct adhesive and grout system. Every seam is finished and inspected before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we hang your chosen enclosure system. Each component is secured correctly to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once all surfaces is tiled, grouted, and enclosed, we perform a careful final inspection. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We walk you through the completed project and confirm everything looks and functions as planned.
