Considering a Tub to Shower Conversion? Read This First
A professionally executed tub to shower conversion can dramatically improve how you use your bathroom every single week. For a growing number of homeowners, the standard bathtub consumes valuable floor space while going unused for months at a time. A tub to shower conversion trades in that underused tub with a functional walk-in shower that fits the way you actually live.

Whether you are aging in place or simply prefer a more efficient shower setup, this guide walks you through all the details — from how the project works to what marks someone an perfect candidate. Read on to learn whether a tub to shower conversion is the right move for your home.
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 framing and plumbing fixtures — is removed and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom layout, your style choices, and whether you need to expand the shower's footprint beyond the original tub's location.
On a mechanical level, the project involves disconnecting the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then building out the new shower base with a proper slope toward the shower drain. New moisture barrier is laid down before any surface covering goes on. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you add.
The outcome is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough transformation to your bathroom's infrastructure and finish.
Major Benefits of a Tub to Shower Conversion
- Reclaimed Floor Space — Standard bathtubs occupy between 13 and 16 square feet. Converting to a curbless shower frees up that square footage to usable, open bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a barrier-free floor transition, grab bars, and a built-in seat to assist homeowners with limited mobility.
- Faster Morning Routines — Most people shower much more frequently than they bathe. A tub to shower conversion redesigns your layout with how you actually use it.
- Stronger Home Appraisals — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to prospective buyers.
- Simpler Upkeep — Shower surrounds and bases are generally easier to clean and maintain than a deep-soaking bathtub with hard-to-reach corners.
- Tailored Aesthetic Selections — From natural stone slabs to frameless glass doors, a tub to shower conversion creates room for many more design directions than a one-piece tub unit.
- Water Efficiency — Soaking in a tub requires roughly 30 to 50 gallons of water per bath. A modern shower valve installed during a tub to shower conversion can reduce consumption to as little as 15 gallons.
- Structural Longevity — When our crew builds a tub to shower conversion, the waterproofing, substrate, and finish materials are built to last through years of daily use.
The Tub to Shower Conversion Procedure Step by Step
- In-Home Evaluation and Scope Review — A remodeling specialist comes to your bathroom to measure your existing space and infrastructure. We discuss your must-haves and finish choices so the project plan aligns with exactly what you want.
- Demolition and Removal — The existing fixtures and surrounding structure are demolished and cleared. Supply and drain lines tied to the old tub are professionally handled to make room for the updated fixture configuration.
- Building the Shower's Foundation — 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 installed across the shower floor and lower walls. The drain area is graded toward the drain to prevent pooling.
- Installing New Shower Plumbing — Skilled tradespeople on our crew set the new plumbing fixtures according to your design plan. Whether you chose a standard showerhead or an upgraded fixture package, everything is installed at this point.
- Finishing the Shower Walls and Floor — Our finish crew set your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every grout joint is finished and checked before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we install your shower door or curtain hardware. Each component is anchored properly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we conduct a room-by-room quality review. Every seam at the perimeter are sealed with mold-resistant silicone caulk. We show you the completed project and verify everything meets your expectations.
Who Is a Suitable 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 is especially relevant for those who find stepping over a tub edge difficult or unsafe — a curbless or low-threshold shower is a genuinely life-improving accessibility changes you can add to your bathroom. Families with young children who previously needed the tub for baths may want to reconsider timing once those children are old enough to shower independently.
A tub to shower conversion also makes sense for anyone with a narrow or tight bathroom footprint where the tub monopolizes the room layout. Getting rid of the old tub and replacing it with a right-sized walk-in shower can make a small bathroom feel significantly larger. That said, if your household has young children who regularly take baths, maintaining a soaking option is something to weigh carefully before scheduling demolition.
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 bathroom that reads modern and updated. Our team at our firm will give you a straight answer if a tub to shower conversion is not in your best interest for your home.
