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 framing and drain assembly — is demolished and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom footprint, your style choices, and whether you need to expand the shower's square footage beyond the original tub's location.
On a structural level, the project involves disconnecting the existing tub drain and supply lines, lifting the tub shell and any surrounding wall material that was tied to it, then framing the new shower pan with a proper slope toward the shower drain. New moisture barrier is installed before any surface covering goes up. Plumbing is modified to fit the new showerhead height and any body sprays, handheld wands, or rain heads you select.
The outcome is a code-compliant shower that performs reliably for many years. A tub to shower conversion done correctly is not just a surface-level change — it is a fundamental improvement to your bathroom's infrastructure and finish.
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 frees up that room to usable, open bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can feature a low-threshold or curbless entry, support handles, and a fold-down bench to assist those who need a safer bathing solution.
- More Efficient Daily Bathing — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion matches your space with how you really live.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion tells buyers the home has been maintained to prospective buyers.
- Simpler Upkeep — Shower pans, walls, and glass enclosures are generally easier to scrub and wipe down than a deep-soaking bathtub with a surrounding tile enclosure.
- Custom Design Options — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion opens up many more design possibilities than a standard tub surround.
- Reduced Water Use — Running a full bath uses roughly 30 to 50 gallons of water per use. A water-efficient shower fixture installed during a tub to shower conversion can cut that to under 20 gallons per shower.
- Long-Term Durability — When Brother & Brother Builders builds a tub to shower conversion, the underlying systems are constructed to hold up through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A project consultant visits your home to evaluate your existing fixtures and framing. We go over your must-haves and finish choices so the scope of work reflects exactly what you want.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to prepare for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is arguably the most technically demanding stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a full waterproofing membrane is installed across all wet surfaces. The floor base is graded toward the drain to avoid standing water.

- Tile, Stone, or Panel Installation — Skilled installers install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every seam is sealed and reviewed before the enclosure goes in.

- Quality Check and Project Sign-Off — Once all surfaces is complete, we do a thorough final inspection. Every seam at the perimeter are caulked with professional-grade caulk. We walk you through the finished shower and make sure everything is exactly what you wanted.
