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 taken out and replaced with a purpose-built shower unit. The complexity of the project is shaped by your existing bathroom footprint, your style choices, and whether you need to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the work involves capping the existing tub drain and supply lines, lifting the tub unit and any old tile surround that was tied to it, then building out the new shower pan with a correct slope toward the center drain. New moisture barrier is installed before any finish material goes on. Plumbing is adjusted to fit the new showerhead height and any extra spray features you add.
The finished product is a structurally sound shower that performs reliably for the long term. A tub to shower conversion done right is not just a surface-level change — it is a complete transformation to your bathroom's structure and usability.

The Tub to Shower Conversion Project Step by Step
- Initial Consultation and Planning — A project consultant visits your home to measure your existing space and infrastructure. We go over your must-haves and finish choices so the project plan aligns with exactly what you want.
- Tub Extraction and Teardown — The existing fixtures and surrounding structure are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to set the stage for the revised drain placement.
- 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 attached to the structural framing, and a continuous waterproof layer is installed across all wet surfaces. The floor base is pitched properly to prevent pooling.
- Installing New Shower Plumbing — Our plumbing team install the new plumbing fixtures according to your fixture selections. Whether you selected a standard showerhead or an upgraded fixture package, everything is installed at this stage.
- Finishing the Shower Walls and Floor — Our finish crew set your selected finish material using appropriate mortar, grout, and setting materials. Every seam is grouted and checked before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we mount your chosen enclosure system. All hardware is set into the tile or framing to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we conduct a careful walk-through. Every seam at the base and wall corners are caulked with flexible waterproof sealant. We review with you the finished shower and verify everything looks and functions as planned.
