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 hardware — is demolished and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your design preferences, 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, 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 code-compliant slope toward the center drain. New waterproof liner is applied before any surface covering goes in. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you select.
The finished product is a fully waterproofed shower that performs reliably for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a thorough transformation to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a custom shower stall returns that room to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a zero-entry design, safety rails, and a built-in seat to support homeowners with limited mobility.
- Quicker Showers — The majority of adults shower far more often than they bathe. A tub to shower conversion matches your space with how you spend your time.
- Better Return on Investment — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Easier Cleaning — Shower floors and walls are typically faster to scrub and wipe down than a standard bathtub with hard-to-reach corners.
- Tailored Aesthetic Selections — From natural stone slabs to frameless glass doors, a tub to shower conversion creates room for significantly broader design options than a standard tub surround.
- Reduced Water Use — Soaking in a tub consumes roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can lower usage to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A member of our team visits your home to evaluate your existing space and infrastructure. We discuss your wishlist and timeline so the scope of work aligns with exactly what you need.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to set the stage for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is widely considered the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is fastened to the structural framing, and a continuous waterproof layer is installed across all wet surfaces. The shower pan is sloped correctly to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new rough-in plumbing according to your design plan. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this point.
- Applying Your Chosen Finish Materials — Our finish crew install your selected finish material using appropriate mortar, grout, and setting materials. Every grout joint is finished and reviewed before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your selected style, we mount your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is anchored properly to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once the full shower is tiled, grouted, and enclosed, we conduct a thorough quality review. Each transition joint at corners and the floor-to-wall transition are finished with professional-grade caulk. We review with you the finished shower and confirm everything meets your expectations.
Who Is a Suitable Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are usually perfect for a tub to shower conversion. This includes those who find stepping over a tub edge difficult or unsafe — a curbless or low-threshold shower is among the most meaningful accessibility changes you can add to your bathroom. Families with young children who previously needed the tub for bathing little ones may also benefit once those children are shower-age.

Eliminating the bathtub and replacing it with a right-sized walk-in shower can open up the entire room. However, if your home only has one bathroom, keeping at least one bathtub is worth discussing before moving forward.
