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 surround and plumbing fixtures — is removed and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you plan to expand the shower's usable area beyond the original tub's location.
On a structural level, the project involves rerouting the existing tub drain and supply lines, lifting the tub unit and any old tile surround that was tied to it, then framing the new shower base with a code-compliant slope toward the center drain. New moisture barrier is applied before any surface covering goes on. Plumbing is adjusted to serve the new showerhead location and any body sprays, handheld wands, or rain heads you select.
The outcome is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done right is not just a visual change — it is a thorough upgrade to your bathroom's infrastructure and finish.

The Tub to Shower Conversion Process Step by Step
- Project Assessment and Design — A remodeling specialist meets with you on-site to assess your existing fixtures and framing. We discuss your must-haves and finish choices so the proposal aligns with exactly what you need.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Any plumbing connections tied to the old tub are professionally handled to make room for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is often the most critical stage of a tub to shower conversion. New waterproof backer material is attached to the framing, and a industry-standard moisture barrier is installed across every area that will contact water. The drain area is pitched properly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew set the new plumbing fixtures according to your chosen layout. Whether you went with a standard showerhead or an upgraded fixture package, everything is installed at this phase.
- Finishing the Shower Walls and Floor — Skilled installers install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every grout joint is grouted and inspected before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your selected style, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is anchored properly to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is complete, we conduct a thorough walk-through. Each transition joint at corners and the floor-to-wall transition are sealed with flexible waterproof sealant. We review with you the completed project and make sure everything meets your expectations.
