Considering a Tub to Shower Conversion? Here's What You Should Know
A thoughtfully designed tub to shower conversion can fundamentally transform how you use your bathroom every single day. For many homeowners, the standard bathtub occupies valuable floor space while sitting empty for months at a time. A tub to shower conversion swaps out that underused tub with a practical walk-in shower that matches the way you actually bathe.

Keep reading to see whether a tub to shower conversion is the best option for your bathroom.
What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom layout, your design preferences, and whether you want to expand the shower's footprint beyond the original tub's space.
On a structural level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub unit and any tile, drywall, or backer board that was tied to it, then building out the new shower pan with a correct slope toward the shower drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes in. Plumbing is adjusted to serve the new showerhead location and any additional fixtures you add.
The result is a structurally sound shower that performs reliably 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 structure and usability.
Key Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower frees up that area to usable, open bathroom space.
- Aging-in-Place Functionality — A tub to shower conversion can include a low-threshold or curbless entry, grab bars, and a fold-down bench to support homeowners with limited mobility.
- Quicker Showers — Most people shower much more frequently than they bathe. A tub to shower conversion aligns your bathroom with how you really live.
- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
- Lower Maintenance Demands — Shower pans, walls, and glass enclosures are typically faster to clean and maintain than a full-length bathtub with grout lines on all four sides.
- Tailored Aesthetic Selections — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion creates room for significantly broader design options than a one-piece tub unit.
- Reduced Water Use — Filling a bathtub uses roughly 30 to 50 gallons of water per session. A water-efficient shower fixture installed during a tub to shower conversion can reduce consumption to under 20 gallons per shower.
- Long-Term Durability — When our crew builds a tub to shower conversion, the underlying systems are designed for durability well beyond 20 years.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A member of our team visits your home to measure your existing space and infrastructure. We review your wishlist and timeline so the scope of work matches exactly what you have in mind.
- Removal of the Existing Tub and Surround — The existing bathtub, tub surround, and any damaged or outdated backer board are taken out. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to make room for the revised drain placement.
- Structural Prep and Moisture Barrier Installation — This is often the most critical stage of a tub to shower conversion. New cement board or tile backer is attached to the wall studs, and a full waterproofing membrane is installed across all wet surfaces. The floor base is sloped correctly to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Skilled tradespeople on our crew set the new plumbing fixtures according to your design plan. Whether you chose a basic or premium shower setup, everything is installed at this stage.
- Tile, Stone, or Panel Installation — Our finish crew install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is finished and checked before moving to the next phase.
- Installing the Shower Enclosure — Depending on your preference, we install your shower door or curtain hardware. Every mounting bracket is secured correctly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we perform a careful quality review. Every seam at corners and the floor-to-wall transition are sealed with mold-resistant silicone caulk. We walk you through the completed project and make sure everything meets your expectations.
Who Is a Good Candidate for a Tub to Shower Conversion?
Anyone who finds the existing tub more of an obstacle than an asset are usually perfect for a tub to shower conversion. This includes aging adults or people with mobility limitations — a zero-entry walk-in shower is one of the most impactful accessibility changes you can add to your bathroom. Households with small kids who previously needed the tub for young children's hygiene routines may want to reconsider timing once the kids are old enough to shower independently.
A tub to shower conversion also makes sense for homeowners in smaller bathrooms where the tub dominates the floor plan. 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, 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 committed to a bathroom that works for years ahead as well as those getting ready to list and looking for 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 best call for your specific layout.
