What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and plumbing fixtures — is taken out and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's footprint beyond the original tub's position.
On a mechanical level, the project involves disconnecting the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then building out the new shower base with a proper slope toward the shower drain. New waterproofing membrane is installed before any finish material goes in. Plumbing is rerouted to accommodate the new showerhead height and any body sprays, handheld wands, or rain heads you add.
The result is a code-compliant shower that functions properly for many years. A tub to shower conversion done right is not just a visual change — it is a fundamental improvement to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower restores that room to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a zero-entry design, safety rails, and a fold-down bench to assist homeowners with limited mobility.
- Faster Morning Routines — The majority of adults shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Better Return on Investment — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to prospective buyers.
- Lower Maintenance Demands — Shower surrounds and bases are typically faster to scrub and wipe down than a standard bathtub with grout lines on all four sides.
- Custom Design Options — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion creates room for many more design directions than a one-piece tub unit.
- Reduced Water Use — Filling a bathtub 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 significantly less water per session.
- Structural Longevity — When our team installs a tub to shower conversion, the structural components are designed for durability well beyond 20 years.

- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to set the stage for the revised drain placement.
- Structural Prep and Moisture Barrier Installation — This is arguably the most critical stage of a tub to shower conversion. New moisture-resistant substrate is fastened to the framing, and a full waterproofing membrane is applied across all wet surfaces. The drain area is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew position the new plumbing fixtures according to your design plan. Whether you selected a basic or premium shower setup, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Our finish crew set your preferred wall and floor covering using professional-grade installation materials. Every grout joint is sealed and inspected before the enclosure goes in.

- Quality Check and Project Sign-Off — Once all surfaces is complete, we perform a thorough walk-through. Each transition joint at corners and the floor-to-wall transition are caulked with professional-grade caulk. We review with you the finished shower and verify everything is exactly what you wanted.
