What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's position.
On a technical level, the work involves rerouting the existing tub drain and supply lines, taking out the tub unit and any old tile surround that was tied to it, then building out the new shower base with a proper slope toward the drain. New waterproofing membrane is installed before any finish material goes on. Plumbing is rerouted to fit the new showerhead position and any extra spray features you select.
The result is a code-compliant shower that performs reliably for decades. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a curbless shower returns that square footage to usable, navigable bathroom space.
- Better Mobility Access — A tub to shower conversion can feature a zero-entry design, support handles, and a shower bench to support homeowners with limited mobility.
- Faster Morning Routines — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion aligns your bathroom with how you actually use it.
- Higher Resale Value — Updated bathrooms reliably appear among the most valued renovations for resale. A tub to shower conversion tells buyers the home has been maintained to real estate agents.
- Simpler Upkeep — Shower surrounds and bases are generally easier to keep spotless than a standard bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion opens up many more design options than a one-piece tub unit.
- Water Efficiency — Filling a bathtub uses roughly 30 to 50 gallons of water per use. A low-flow showerhead installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- 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
- In-Home Evaluation and Scope Review — A remodeling specialist comes to your bathroom to measure your existing fixtures and framing. We discuss your must-haves and finish choices so the proposal matches exactly what you have in mind.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Supply and drain lines tied to the old tub are professionally handled to prepare for the updated fixture configuration.
- Building the Shower's Foundation — This is widely considered the most important stage of a tub to shower conversion. New cement board or tile backer is fastened to the wall studs, and a industry-standard moisture barrier is rolled or troweled on across the shower floor and lower walls. The floor base is pitched properly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new rough-in plumbing according to your chosen layout. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this stage.
- Tile, Stone, or Panel Installation — Skilled installers apply your selected finish material using professional-grade installation materials. Every tile edge is finished and checked before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we hang your chosen enclosure system. Each component is secured correctly to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once the full shower is finished and installed, we do a careful final inspection. Each transition joint at corners and the floor-to-wall transition are finished with professional-grade caulk. We walk you through the finished shower and confirm everything looks and functions as planned.
Who Is a Suitable Candidate for a Tub to Shower Conversion?

Our crew at our firm will give you a straight answer if a tub to shower conversion is not the best call for your particular situation.
