What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is taken out and replaced with a professionally installed shower unit. The scope of the project depends on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's space.

On a mechanical level, the process involves rerouting the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a correct slope toward the center drain. New moisture barrier is installed before any finish material goes on. Plumbing is rerouted to fit the new showerhead location and any extra spray features you choose.

The finished product is a structurally sound shower that performs reliably for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a fundamental improvement 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 curbless shower restores that area to usable, open bathroom space.
• Aging-in-Place Functionality — A tub to shower conversion can include a low-threshold or curbless entry, grab bars, and a fold-down bench to accommodate those who need a safer bathing solution.
• Faster Morning Routines — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you actually use it.
• Stronger Home Appraisals — Updated bathrooms always show up among the top home improvements for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
• Lower Maintenance Demands — Shower surrounds and bases are generally easier to scrub and wipe down than a deep-soaking bathtub with a surrounding tile enclosure.
• Custom Design Options — From subway tile surrounds to frameless glass doors, a tub to shower conversion creates room for many more design possibilities than a one-piece tub unit.
• Water Efficiency — Soaking in a tub uses roughly 30 to 50 gallons of water per session. A low-flow showerhead installed during a tub to shower conversion can cut that to as little as 15 gallons.
• Structural Longevity — When Brother & Brother Builders builds a tub to shower conversion, the waterproofing, substrate, and finish materials are constructed to hold up for decades.

5. Applying Your Chosen Finish Materials — Our finish crew apply your selected finish material using appropriate mortar, grout, and setting materials. Every grout joint is grouted and checked before glass or curtain hardware is installed.
