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 enclosure and drain assembly — is removed and replaced with a purpose-built shower unit. The scope of the project is shaped by your existing bathroom layout, your style choices, and whether you need to expand the shower's square footage beyond the original tub's location.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then constructing the new shower base with a proper slope toward the shower drain. New moisture barrier is applied before any finish material goes on. Plumbing is modified to fit the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The result is a code-compliant shower that functions properly for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs consume between 13 and 16 square feet. Converting to a custom shower stall restores 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 shower bench to support those who need a safer bathing solution.
- Quicker Showers — Most people shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Lower Maintenance Demands — Shower surrounds and bases are generally easier to clean and maintain than a deep-soaking bathtub with hard-to-reach corners.
- Tailored Aesthetic Selections — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion opens up far more 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 water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Long-Term Durability — When our team completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A remodeling specialist comes to your bathroom to measure your existing fixtures and framing. We discuss your wishlist and timeline so the scope of work aligns with exactly what you need.
- Removal of the Existing Tub and Surround — The existing tub unit and wall material are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to prepare for the new shower plumbing layout.
- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the structural framing, and a full waterproofing membrane is installed across all wet surfaces. The shower pan is graded toward the drain to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Our plumbing team set 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 stage.
- Finishing the Shower Walls and Floor — Tile setters install your preferred wall and floor covering using the correct adhesive and grout system. Every seam is sealed and inspected before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your chosen enclosure system. Every mounting bracket is secured correctly to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once the full shower is finished and installed, we conduct a thorough walk-through. Each transition joint at the base and wall corners are sealed with mold-resistant silicone caulk. We show you the final result and verify everything meets your expectations.
