Considering a Tub to Shower Conversion? Start Here
A well-planned tub to shower conversion can dramatically improve how you use your bathroom every single morning.

A tub to shower conversion is among our most popular services we provide, and for clear purposes — it delivers real, lasting improvement without a complete room overhaul.
Whether you are updating an outdated space or simply want a more accessible shower setup, this guide walks you through all the details — from how the process works to what qualifies someone an perfect candidate. Let's get started 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 home renovation service in which an existing bathtub — along with its framing and hardware — is taken out and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom plumbing configuration, your style choices, and whether you need to expand the shower's footprint beyond the original tub's position.
On a structural level, the process 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 constructing the new shower pan with a proper slope toward the shower drain. New waterproofing membrane is installed before any tile, stone, or prefab panel goes in. Plumbing is modified to fit the new showerhead position and any extra spray features you choose.
The outcome is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a fundamental upgrade to your bathroom's infrastructure and finish.
Key Benefits of a Tub to Shower Conversion
- More Usable Bathroom Area — Standard bathtubs take up between 13 and 16 square feet. Converting to a walk-in shower restores that area to usable, navigable bathroom space.
- Improved Accessibility — A tub to shower conversion can feature a barrier-free floor transition, grab bars, and a fold-down bench to support aging adults, people with disabilities, or anyone recovering from surgery.
- More Efficient Daily Bathing — A large portion of homeowners shower far more often than they bathe. A tub to shower conversion redesigns your layout with how you actually use it.
- Stronger Home Appraisals — Updated bathrooms consistently rank among the highest-ROI upgrades for resale. A tub to shower conversion signals modern, move-in-ready conditions to real estate agents.
- Lower Maintenance Demands — Shower surrounds and bases are often simpler to keep spotless than a deep-soaking bathtub with a surrounding tile enclosure.
- Personalized Finish Choices — From subway tile surrounds to heavy-duty shower curtain systems, a tub to shower conversion creates room for far more design directions than a one-piece tub unit.
- Water Efficiency — Soaking in a tub uses roughly 30 to 50 gallons of water per session. A water-efficient shower fixture installed during a tub to shower conversion can cut that to as little as 15 gallons.
- Lasting Construction — When our crew builds a tub to shower conversion, the underlying systems are constructed to hold up through years of daily use.
The Tub to Shower Conversion Process Step by Step
- Project Assessment and Design — A remodeling specialist visits your home to measure your existing tub, plumbing, and bathroom layout. We go over your wishlist and timeline so the project plan reflects exactly what you have in mind.
- Demolition and Removal — The existing tub unit and wall material are taken out. Existing water supply tied to the old tub are professionally handled to prepare for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most technically demanding stage of a tub to shower conversion. New waterproof backer material is screwed to the wall studs, and a continuous waterproof layer is applied across the shower floor and lower walls. The floor base is graded toward the drain to avoid standing water.
- Installing New Shower Plumbing — Our plumbing team install the new rough-in plumbing according to your design plan. 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 — Skilled installers apply your selected finish material using the correct adhesive and grout system. Every seam is finished and reviewed before glass or curtain hardware is installed.
- Installing the Shower Enclosure — Depending on your design choice, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is secured correctly to ensure years of smooth, wobble-free operation.
- Quality Check and Project Sign-Off — Once all surfaces is complete, we perform a careful walk-through. All caulk joints at corners and the floor-to-wall transition are caulked with professional-grade caulk. We review with you the final result and confirm everything is exactly what you wanted.
