What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the work involves capping the existing tub drain and supply lines, removing the tub itself and any read more surrounding wall material that was tied to it, then framing the new shower pan with a proper slope toward the shower drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes on. Plumbing is modified to accommodate the new showerhead height and any extra spray features you add.
The finished product is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done correctly is not just a visual change — it is a fundamental transformation to your bathroom's infrastructure and finish.
Top Benefits of a Tub to Shower Conversion
- Better Use of Square Footage — Standard bathtubs take up between 13 and 16 square feet. Converting to a custom shower stall restores that square footage to usable, accessible bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a zero-entry design, safety rails, and a shower bench to support those who need a safer bathing solution.
- More Efficient Daily Bathing — The majority of adults shower significantly more than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Higher Resale Value — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion signals modern, move-in-ready conditions to future owners.
- Simpler Upkeep — Shower floors and walls are typically faster to scrub and wipe down than a full-length bathtub with grout lines on all four sides.
- Personalized Finish Choices — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion unlocks many more design possibilities than a prefab tub kit.
- Water Efficiency — Running a full bath requires roughly 30 to 50 gallons of water per use. A modern shower valve installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Lasting Construction — When Brother & Brother Builders completes a tub to shower conversion, the waterproofing, substrate, and finish materials are designed for durability well beyond 20 years.
The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A project consultant meets with you on-site to evaluate your existing fixtures and framing. We go over your wishlist and timeline so the project plan reflects exactly what you want.
- Demolition and Removal — 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 disconnected, capped, or rerouted to prepare for the updated fixture configuration.
- Building the Shower's Foundation — This is arguably the most important stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the wall studs, and a full waterproofing membrane is installed across every area that will contact water. The shower pan is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Skilled tradespeople on our crew position the new rough-in plumbing according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this point.
- Tile, Stone, or Panel Installation — Our finish crew apply your preferred wall and floor covering using the correct adhesive and grout system. Every tile edge is finished and reviewed before moving to the next phase.
- Installing the Shower Enclosure — Depending on your preference, we install your shower door or curtain hardware. Each component is secured correctly to prevent loosening over time.
- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we perform a thorough final inspection. Each transition joint at the base and wall corners are finished with mold-resistant silicone caulk. We show you the completed project and confirm everything looks and functions as planned.
Who Is a Good Candidate for a Tub to Shower Conversion?
