Whether you are updating an outdated space or simply want a more modern shower setup, this overview walks you through the full picture — from how the process works to what makes someone an great candidate. Let's get started to find out whether a tub to shower conversion is the best option for your bathroom.
What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is removed and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom footprint, 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 rerouting the existing tub drain and supply lines, taking out the tub itself and any old tile surround that was tied to it, then framing the new shower floor with a proper slope toward the center drain. New waterproof liner is laid down before any surface covering goes in. Plumbing is adjusted to fit the new showerhead location and any additional fixtures you select.
The result is a code-compliant shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a visual change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a walk-in shower restores that area to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a low-threshold or curbless entry, safety rails, and a fold-down bench to assist homeowners with limited mobility.
- Faster Morning Routines — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Higher Resale Value — Updated bathrooms reliably appear among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to real estate agents.
- Lower Maintenance Demands — Shower floors and walls are often simpler to clean and maintain than a full-length bathtub with grout lines on all four sides.
- Personalized Finish Choices — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion opens up far more design directions than a prefab tub kit.
- Lower Utility Bills — Soaking in a tub requires roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Lasting Construction — When our crew completes a tub to shower conversion, the underlying systems are built to last for decades.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist meets with you on-site to measure your existing space and infrastructure. We review your goals, design preferences, and budget so the scope of work reflects exactly what you have in mind.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Existing water supply tied to the old tub are properly shut off to make room for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is arguably the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a continuous waterproof layer is rolled or troweled on across all wet surfaces. The floor base is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Our plumbing team set the new rough-in plumbing according to your chosen layout. Whether you went with a basic or premium shower setup, everything is installed at this stage.
- Applying Your Chosen Finish Materials — Tile setters install your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every tile edge is sealed and inspected before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your preference, we mount your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we perform a careful final inspection. Every seam at the base and wall corners are caulked with mold-resistant silicone caulk. We walk you through the completed project and verify everything is exactly what you wanted.
