Thinking About a Tub to Shower Conversion? Here's What You Should Know
A thoughtfully designed tub to shower conversion can fundamentally transform how you use your bathroom every single week.

Whether you are aging in place or simply want a more accessible shower setup, this article walks you through everything — from how the conversion works to what makes someone an perfect candidate. Let's get started to see whether a tub to shower conversion is the right move for your space.
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 framing and drain assembly — is removed and replaced with a professionally installed shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's square footage beyond the original tub's space.
On a structural level, the project involves capping the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a proper slope toward the shower drain. New waterproof liner is laid down before any tile, stone, or prefab panel goes in. Plumbing is modified to serve the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The outcome is a structurally sound shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
Key Benefits of a Tub to Shower Conversion

- Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Easier Cleaning — 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 large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion creates room for many more design options than a standard tub surround.
- Lower Utility Bills — Filling a bathtub uses roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Structural Longevity — When Brother & Brother Builders completes a tub to shower conversion, the structural components are built to last through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant meets with you on-site to evaluate your existing space and infrastructure. We review your wishlist and timeline so the scope of work matches exactly what you want.
- Tub Extraction and Teardown — 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 prepare for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is often the most technically demanding stage of a tub to shower conversion. New waterproof backer material is attached to the wall studs, and a continuous waterproof layer is applied across all wet surfaces. The shower pan is sloped correctly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Our plumbing team position the new shower valve, drain body, and supply lines according to your chosen layout. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — Our finish crew apply your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every seam is sealed and inspected before moving to the next phase.
- Installing the Shower Enclosure — Depending on your selected style, we install your chosen enclosure system. All hardware is anchored properly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is tiled, grouted, and enclosed, we perform a careful final inspection. Every seam at corners and the floor-to-wall transition are caulked with mold-resistant silicone caulk. We walk you through the finished shower and verify everything is exactly what you wanted.
