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 enclosure and drain assembly — is removed and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you want to expand the shower's footprint beyond the original tub's position.
On a structural level, the process involves capping the existing tub drain and supply lines, taking out the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a code-compliant slope toward the shower drain. New waterproofing membrane is laid down before any finish material goes on. Plumbing is rerouted to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The outcome is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done right is not just a surface-level change — it is a fundamental transformation to your bathroom's infrastructure and finish.
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 walk-in shower restores that area to usable, navigable bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can incorporate a zero-entry design, grab bars, and a shower bench to accommodate those who need a safer bathing solution.
- Quicker Showers — Most people shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you really live.
- Stronger Home Appraisals — Updated bathrooms reliably appear among the top home improvements for resale. A tub to shower conversion communicates updated finishes to future owners.
- Lower Maintenance Demands — Shower pans, walls, and glass enclosures are typically faster to clean and maintain than a deep-soaking bathtub with a surrounding tile enclosure.
- Custom Design Options — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion unlocks many more design possibilities than a prefab tub kit.
- Lower Utility Bills — Filling a bathtub consumes roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can lower usage to as little as 15 gallons.
- Long-Term Durability — When our team completes a tub to shower conversion, the waterproofing, substrate, and finish materials are built to last well beyond 20 years.
The Tub to Shower Conversion Project Step by Step
- Project Assessment and Design — A project consultant meets with you on-site to measure your existing tub, plumbing, and bathroom layout. We review your wishlist and timeline so the proposal matches exactly what you need.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Supply and drain lines tied to the old tub are professionally handled to make room for the revised drain placement.
- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the framing, and a full waterproofing membrane is installed across every area that will contact water. The floor base is sloped correctly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Our plumbing team position the new shower valve, drain body, and supply lines according to your design plan. Whether you went with a basic or premium shower setup, everything is roughed in at this point.
- Tile, Stone, or Panel Installation — Skilled installers apply your preferred wall and floor covering using professional-grade installation materials. Every seam is sealed and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your shower door or curtain hardware. All hardware is secured correctly to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once the full shower is complete, we perform a room-by-room walk-through. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We show you the finished shower and confirm everything is exactly what you wanted.
Who Is a Good Candidate for a Tub to Shower Conversion?

Getting rid of the old tub and replacing it with a right-sized walk-in shower can dramatically improve the sense of space. However, if your household has young children who regularly take baths, preserving a full bath somewhere in the home is a conversation we always have with clients before scheduling demolition.
