What Really 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 plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom footprint, your design preferences, and whether you need to expand the shower's footprint beyond the original tub's position.
On a structural level, the work involves rerouting the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then constructing the new shower pan with a code-compliant slope toward the center drain. New waterproof liner is installed before any tile, stone, or prefab panel goes up. Plumbing is modified to fit the new showerhead height and any here additional fixtures you select.
The result is a fully waterproofed shower that performs reliably for decades. A tub to shower conversion done right is not just a cosmetic change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
Major Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a custom shower stall restores that square footage to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a zero-entry design, safety rails, and a shower bench to accommodate aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — The majority of adults shower far more often than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Better Return on Investment — Updated bathrooms consistently rank among the top home improvements for resale. A tub to shower conversion tells buyers the home has been maintained to prospective buyers.
- Simpler Upkeep — Shower floors and walls are often simpler to clean and maintain than a full-length bathtub with a surrounding tile enclosure.
- Custom Design Options — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion opens up significantly broader design directions than a one-piece tub unit.
- Water Efficiency — 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 cut that to under 20 gallons per shower.
- Structural Longevity — When our team completes a tub to shower conversion, the structural components are constructed to hold up through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A project consultant visits your home to evaluate your existing space and infrastructure. We discuss your must-haves and finish choices so the scope of work aligns with exactly what you have in mind.
- Tub Extraction and Teardown — The existing tub unit and wall material are taken out. Supply and drain lines tied to the old tub are professionally handled to set the stage for the revised drain placement.
- Framing, Waterproofing, and Substrate Work — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is fastened to the framing, and a continuous waterproof layer is rolled or troweled on across the shower floor and lower walls. The shower pan is pitched properly to ensure drainage.
- Installing New Shower Plumbing — Our plumbing team set the new plumbing fixtures according to your fixture selections. Whether you went with a basic or premium shower setup, everything is roughed in at this phase.
- Applying Your Chosen Finish Materials — Our finish crew set your preferred wall and floor covering using the correct adhesive and grout system. Every tile edge is sealed and checked before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we install your shower door or curtain hardware. All hardware is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once the full shower is complete, we conduct a room-by-room walk-through. Each transition joint at the perimeter are finished with flexible waterproof sealant. We walk you through the finished shower and make sure everything looks and functions as planned.
