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 hardware — is removed and replaced with a professionally installed shower unit. The scale of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you need to expand the shower's footprint beyond the original tub's space.
On a technical level, the process involves disconnecting the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then constructing the new shower floor with a code-compliant slope toward the shower drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes up. Plumbing is adjusted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you choose.
The finished product is a structurally sound shower that performs reliably for decades. A tub to shower conversion done right is not just a visual change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
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 walk-in shower frees up that square footage to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a low-threshold or curbless entry, safety rails, and a fold-down bench to accommodate aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — Most people shower far more often than they bathe. A tub to shower conversion aligns your bathroom with how you spend your time.
- Better Return on Investment — Updated bathrooms reliably appear among the highest-ROI upgrades 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 often simpler to clean and maintain than a standard bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From subway tile surrounds to semi-frameless enclosures, a tub to shower conversion opens up many more design directions than a standard tub surround.
- Water Efficiency — Soaking in a tub consumes roughly 30 to 50 gallons of water per session. A modern shower valve installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- Lasting Construction — When our team completes a tub to shower conversion, the structural components are constructed to hold up well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A member of our team comes to your bathroom to measure your existing tub, plumbing, and bathroom layout. We discuss your goals, design preferences, and budget so the proposal aligns with exactly what you want.
- Demolition and Removal — The existing fixtures and surrounding structure are carefully removed. Any plumbing connections tied to the old tub are professionally handled to prepare for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is often the most important stage of a tub to shower conversion. New waterproof backer material is fastened to the structural framing, and a continuous waterproof layer is applied across all wet surfaces. The floor base is pitched properly to prevent pooling.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew position the new plumbing fixtures according to your fixture selections. Whether you chose a basic or premium shower setup, everything is positioned at this stage.
- Applying Your Chosen Finish Materials — Tile setters install your selected finish material using appropriate mortar, grout, and setting materials. Every seam is grouted and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your design choice, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is set into the tile or framing to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once everything is finished and installed, we perform a room-by-room final inspection. Every seam at corners and the floor-to-wall transition are sealed with mold-resistant silicone caulk. We review with you the completed project and confirm everything is exactly what you wanted.
Who Is a Strong Candidate for a Tub to Shower Conversion?
Homeowners who rarely or never use their bathtub are usually perfect for a tub to shower conversion. This also applies to homeowners who struggle with high tub walls — a curbless or low-threshold shower is a genuinely life-improving accessibility changes you can make to your bathroom. Parents of toddlers who previously needed the tub for baths may find value in a conversion once those children are old enough to shower independently.
A tub to shower conversion also works well for homeowners in smaller bathrooms where the tub monopolizes the floor plan. Eliminating the bathtub and replacing it with a right-sized walk-in shower can dramatically improve the sense of space. However, if your home only has one bathroom, keeping at least one bathtub is something to weigh carefully before moving forward.
Candidates who benefit most from a tub to shower conversion are those investing in their primary residence as well as those staging for the real estate market and wanting a polished, move-in-ready space. Our crew at our firm will give you a straight answer if a tub to shower conversion is not the right fit for your particular situation.
