Let's get started to find out whether a tub to shower conversion is the right move for your bathroom.

What Really Is a Tub to Shower Conversion?

A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and hardware — is taken out and replaced with a purpose-built shower unit. The scope of the project varies based on your existing bathroom footprint, your finish selections, and whether you want to expand the shower's usable area beyond the original tub's space.

On a structural level, the work involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then framing the new shower base with a correct slope toward the shower drain. New moisture barrier is installed before any tile, stone, or prefab panel goes up. Plumbing is adjusted to fit the new showerhead height and any additional fixtures you choose.

The outcome is a structurally sound shower that performs reliably for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.

Key Benefits of a Tub to Shower Conversion

• Aging-in-Place Functionality — A tub to shower conversion can incorporate a barrier-free floor transition, grab bars, and a built-in seat to accommodate those who need a safer bathing solution.
• Faster Morning Routines — A large portion of homeowners shower significantly more than they bathe. A tub to shower conversion matches your space with how you actually use it.
• Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
• Simpler Upkeep — Shower pans, walls, and glass enclosures are generally easier to scrub and wipe down than a deep-soaking bathtub with hard-to-reach corners.
• Personalized Finish Choices — From natural stone slabs to semi-frameless enclosures, a tub to shower conversion unlocks far more design directions than a one-piece tub unit.
• Lower Utility Bills — Soaking in a tub consumes roughly 30 to 50 gallons of water per use. 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 installs a tub to shower conversion, the underlying systems are built to last well beyond 20 years.

The Tub to Shower Conversion Process Step by Step

1. Initial Consultation and Planning — A member of our team visits your home to measure your existing tub, plumbing, and bathroom layout. We review your must-haves and finish choices so the proposal reflects exactly what you have in mind.
2. 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 professionally handled to prepare for the revised drain placement.
3. Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New cement board or tile backer is fastened to the structural framing, and a continuous waterproof layer is installed across every area that will contact water. The floor base is graded toward the drain to avoid standing water.
4. Installing New Shower Plumbing — Skilled tradespeople on our crew position the new shower valve, drain body, and supply lines according to your design plan. Whether you selected a basic or premium shower setup, everything is installed at this phase.
5. Applying Your Chosen Finish Materials — Tile setters install your preferred wall and floor covering using the correct adhesive and grout system. Every grout joint is grouted and checked before glass or curtain hardware is installed.
6. Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is set into the tile or framing to ensure years of smooth, wobble-free operation.
7. Completion Walk-Through and Finishing Touches — Once the full shower is finished and installed, we do a careful walk-through. Each transition joint at the base and wall corners are finished with flexible waterproof sealant. We show you the completed project and confirm everything is exactly what you wanted.
