Whether you are updating an outdated space or simply need a more efficient shower setup, this guide walks you through all the details — from how the project works to what qualifies someone an perfect candidate. Read on to see whether a tub to shower conversion is a smart choice for your home.
What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and hardware — is demolished and replaced with a professionally installed shower unit. The scale of the project varies based on your existing bathroom footprint, your style choices, and whether you plan 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 tile, drywall, or backer board that was tied to it, then framing the new shower pan with a proper slope toward the drain. New moisture barrier is applied before any finish material goes in. Plumbing is modified to serve the new showerhead position and any body sprays, handheld wands, or rain heads you select.
The result is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a fundamental transformation 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 returns that area to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can feature a low-threshold or curbless entry, grab bars, and a fold-down bench to accommodate those who need a safer bathing solution.
- Quicker Showers — A large portion of homeowners shower much more frequently than they bathe. A tub to shower conversion matches your space with how you actually use it.
- Stronger Home Appraisals — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to real estate agents.
- Lower Maintenance Demands — Shower surrounds and bases are typically faster to scrub and wipe down than a standard bathtub with hard-to-reach corners.
- Personalized Finish Choices — From large-format porcelain tiles to semi-frameless enclosures, a tub to shower conversion opens up significantly broader design options than a prefab tub kit.
- Water Efficiency — Filling a bathtub requires roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can cut that to significantly less water per session.
- Long-Term Durability — When our crew completes a tub to shower conversion, the structural components are built to last through years of daily use.
The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A remodeling specialist comes to your bathroom to evaluate your existing tub, plumbing, and bathroom layout. We go over your goals, design preferences, and budget so the scope of work reflects exactly what you want.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to make room for the new shower plumbing layout.
- Building the Shower's Foundation — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The shower pan is pitched properly to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew position the new shower valve, drain body, and supply lines according to your fixture selections. Whether you went with a standard showerhead or an upgraded fixture package, everything is installed at this phase.
- Applying Your Chosen Finish Materials — Tile setters install your preferred wall and floor covering using professional-grade installation materials. Every grout joint is grouted and inspected before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is secured correctly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once the full shower is finished and installed, we perform a thorough walk-through. All caulk joints at the perimeter are finished with professional-grade caulk. We show you the finished shower and confirm everything looks and functions as planned.

Our experts at Brother & Brother Builders will always be honest if a tub to shower conversion is not the best call for your particular situation.
