Thinking About a Tub to Shower Conversion? Read This First
A well-planned tub to shower conversion can fundamentally transform how you use your bathroom every single day.

What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and drain assembly — is taken out and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom plumbing configuration, your design preferences, and whether you want to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the process involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then constructing the new shower floor with a correct slope toward the shower drain. New waterproof liner is laid down before any tile, stone, or prefab panel goes in. Plumbing is rerouted to serve the new showerhead height and any extra spray features you choose.
The finished product is a fully waterproofed shower that performs reliably for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete improvement to your bathroom's structure and usability.
Major Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower restores that area to usable, accessible bathroom space.
- Better Mobility Access — A tub to shower conversion can include a zero-entry design, grab bars, and a fold-down bench to accommodate aging adults, people with disabilities, or anyone recovering from surgery.
- Quicker Showers — The majority of adults shower much more frequently than they bathe. A tub to shower conversion redesigns your layout with how you spend your time.
- Stronger Home Appraisals — Updated bathrooms reliably appear among the top home improvements for resale. A tub to shower conversion tells buyers the home has been maintained to prospective buyers.
- Lower Maintenance Demands — Shower floors and walls are often simpler to scrub and wipe down than a standard bathtub with a surrounding tile enclosure.
- Tailored Aesthetic Selections — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion unlocks many more design options than a standard tub surround.
- Lower Utility Bills — Filling a bathtub requires roughly 30 to 50 gallons of water per bath. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to as little as 15 gallons.
- Structural Longevity — When Brother & Brother Builders completes a tub to shower conversion, the underlying systems are designed for durability well beyond 20 years.
The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A remodeling specialist meets with you on-site to assess your existing space and infrastructure. We review your must-haves and finish choices so the project plan aligns with exactly what you have in mind.
- Demolition and Removal — The existing tub unit and wall material are carefully removed. Supply and drain lines 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 framing, and a industry-standard moisture barrier is rolled or troweled on across the shower floor and lower walls. The drain area 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 design plan. Whether you selected a basic or premium shower setup, everything is roughed in at this point.
- Applying Your Chosen Finish Materials — Tile setters apply your selected finish material using appropriate mortar, grout, and setting materials. Every tile edge is grouted and reviewed before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is anchored properly to provide a solid, long-lasting result.
- Quality Check and Project Sign-Off — Once everything is complete, we conduct a thorough final inspection. Each transition joint at the perimeter are caulked with professional-grade caulk. We show you the completed project and make sure everything looks and functions as planned.
Who Is a Good 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 also applies to aging adults or people with mobility limitations — a barrier-free shower conversion is among the most meaningful accessibility modifications you can add to your bathroom. Families with young children who previously needed the tub for young children's hygiene routines may find value in a conversion once the kids are old enough to shower independently.
A tub to shower conversion also works well for anyone with a narrow or tight bathroom footprint where the tub consumes the available area. Getting rid of the old tub and replacing it with a right-sized walk-in shower can dramatically improve the sense of space. That said, if your home only has one bathroom, keeping at least one bathtub is a conversation we always have with clients before scheduling demolition.
Those who see the greatest return from a tub to shower conversion are those committed to a bathroom that works for years ahead as well as those preparing to sell and wanting a bathroom that reads modern and updated. Our crew at Brother & Brother Builders will always be honest if a tub to shower conversion is not the best call for your specific layout.
