Thinking About a Tub to Shower Conversion? Here's What You Should Know
A professionally executed tub to shower conversion can completely change how you use your bathroom every single morning. For many homeowners, the standard bathtub consumes valuable floor space while going unused for months at a time.

Whether you are updating an outdated space or simply need a more accessible shower setup, this guide walks you through everything — from how the process works to what qualifies someone an ideal candidate. Let's get started to find out whether a tub to shower conversion is the right move for your bathroom.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and drain assembly — is removed and replaced with a purpose-built shower unit. The scope of the project is shaped by your existing bathroom footprint, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's space.
On a structural level, the project involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then framing the new shower floor with a correct slope toward the shower drain. New waterproof liner is applied before any tile, stone, or prefab panel goes on. Plumbing is modified to serve the new showerhead height and any extra spray features you add.
The outcome is a code-compliant shower that performs reliably for the long term. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower restores that room to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can include a barrier-free floor transition, support handles, and a shower bench to support homeowners with limited mobility.
- More Efficient Daily Bathing — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion aligns your bathroom with how you actually use it.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
- Lower Maintenance Demands — Shower surrounds and bases are often simpler to clean and maintain than a deep-soaking bathtub with hard-to-reach corners.
- Custom Design Options — From subway tile surrounds to frameless glass doors, a tub to shower conversion unlocks significantly broader design options than a prefab tub kit.
- Water Efficiency — Running a full bath requires roughly 30 to 50 gallons of water per session. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Lasting Construction — When our crew installs a tub to shower conversion, the underlying systems are built to last for decades.
The Tub to Shower Conversion Process Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist visits your home to assess your existing tub, plumbing, and bathroom layout. We discuss your goals, design preferences, and budget so the proposal reflects exactly what you need.
- Tub Extraction and Teardown — The existing fixtures and surrounding structure are carefully removed. Supply and drain lines 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 often the most important stage of a tub to shower conversion. New waterproof backer material is fastened to the wall studs, and a full waterproofing membrane is installed across every area that will contact water. The shower pan is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew position the new plumbing fixtures according to your fixture selections. Whether you selected a standard showerhead or an upgraded fixture package, everything is installed at this stage.
- Finishing the Shower Walls and Floor — Tile setters set your preferred wall and floor covering using the correct adhesive and grout system. Every seam is grouted and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we mount your shower door or curtain hardware. Each component is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once the full shower is tiled, grouted, and enclosed, we do a thorough quality review. Every seam at the base and wall corners are finished with flexible waterproof sealant. We review with you the finished shower and make sure everything meets your expectations.

Our crew at Brother & Brother Builders will tell you plainly if a tub to shower conversion is not in your best interest for your specific layout.
