Whether you are updating an outdated space or simply want a more modern shower setup, this article walks you through the full picture — from how the process works to what qualifies someone an ideal candidate. Read on to find out whether a tub to shower conversion is a smart choice for your bathroom.
What Exactly 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 plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a structural level, the process involves rerouting 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 base with a proper slope toward the drain. New waterproofing membrane is installed before any finish material goes in. Plumbing is modified to serve the new showerhead location and any additional fixtures you add.
The outcome is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done right is not just a surface-level change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs consume between 13 and 16 square feet. Converting to a curbless shower restores that square footage to usable, open bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a barrier-free floor transition, support handles, and a fold-down bench to assist homeowners with limited mobility.
- Quicker Showers — 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 reliably appear among the highest-ROI upgrades for resale. A tub to shower conversion tells buyers the home has been maintained to future owners.
- Lower Maintenance Demands — Shower surrounds and bases are generally easier to keep spotless 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 significantly broader design options than a prefab tub kit.
- Lower Utility Bills — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to significantly less water per session.
- Structural Longevity — When our crew installs a tub to shower conversion, the underlying systems are built to last through years of daily use.
The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A member of our team comes to your bathroom to measure your existing tub, plumbing, and bathroom layout. We go over your must-haves and finish choices so the scope of work matches exactly what you need.
- Demolition and Removal — The existing fixtures and surrounding structure are taken out. Supply and drain lines tied to the old tub are properly shut off to prepare for the updated fixture configuration.
- Structural Prep and Moisture Barrier Installation — This is arguably the most critical stage of a tub to shower conversion. New waterproof backer material is attached to the wall studs, and a industry-standard moisture barrier is installed across every area that will contact water. The floor base is sloped correctly to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Our plumbing team set the new shower valve, drain body, and supply lines according to your fixture selections. Whether you chose a standard showerhead or an upgraded fixture package, everything is positioned at this point.
- Applying Your Chosen Finish Materials — Tile setters set your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every grout joint is finished and reviewed before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we mount your chosen enclosure system. Each component is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is tiled, grouted, and enclosed, we conduct a room-by-room final inspection. Each transition joint at the perimeter are caulked with flexible waterproof sealant. We show you the completed project and verify everything is exactly what you wanted.
