What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and drain assembly — is removed and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's location.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, removing the tub unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower base with a correct slope toward the shower drain. New waterproof liner is laid down before any surface covering goes up. Plumbing is modified to accommodate the new showerhead height and any additional fixtures you select.
The result is a code-compliant shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental transformation to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a custom shower stall frees up that room to usable, accessible bathroom space.
- Better Mobility Access — A tub to shower conversion can feature a low-threshold or curbless entry, grab bars, and a built-in seat to accommodate homeowners with limited mobility.
- Faster Morning Routines — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Stronger Home Appraisals — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to real estate agents.
- Easier Cleaning — Shower floors and walls are often simpler to scrub and wipe down than a standard bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion opens up significantly broader design possibilities than a prefab tub kit.
- Water Efficiency — Running a full bath uses roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Structural Longevity — When our crew builds a tub to shower conversion, the structural components are designed for durability for decades.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to measure your existing space and infrastructure. We go over your goals, design preferences, and budget so the scope of work matches exactly what you need.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Supply and drain lines tied to the old tub are properly shut off to prepare for the new shower plumbing layout.
- Building the Shower's Foundation — This is often the most critical stage of a tub to shower conversion. New waterproof backer material is attached to the wall studs, and a full waterproofing membrane is installed across every area that will contact water. The drain area is pitched properly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new shower valve, drain body, and supply lines according to your fixture selections. Whether you selected a basic or premium shower setup, everything is roughed in at this point.
- Finishing the Shower Walls and Floor — Skilled installers set your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every tile edge is finished and inspected before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is set into the tile or framing to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once the full shower is complete, we conduct a room-by-room quality review. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We show you the final result and confirm everything meets your expectations.

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