What Actually Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its framing and plumbing fixtures — is demolished and replaced with a professionally installed shower unit. The scope of the project is shaped by your existing bathroom website footprint, your design preferences, and whether you want to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the process involves disconnecting 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 proper slope toward the shower drain. New moisture barrier is applied before any finish material goes up. Plumbing is rerouted to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The outcome is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Process Step by Step
- Initial Consultation and Planning — A project consultant meets with you on-site to evaluate your existing tub, plumbing, and bathroom layout. We go over your goals, design preferences, and budget so the proposal aligns with exactly what you want.
- Removal of the Existing Tub and Surround — The existing fixtures and surrounding structure are carefully removed. Supply and drain lines tied to the old tub are disconnected, capped, or rerouted to make room for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the structural framing, and a industry-standard moisture barrier is installed across all wet surfaces. The floor base is graded toward the drain to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Our plumbing team position the new shower valve, drain body, and supply lines according to your fixture selections. Whether you selected a basic or premium shower setup, everything is installed at this phase.
- Finishing the Shower Walls and Floor — Tile setters install your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every grout joint is finished and inspected before glass or curtain hardware is installed.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we install your chosen enclosure system. Each component is secured correctly to ensure years of smooth, wobble-free operation.
- Completion Walk-Through and Finishing Touches — Once all surfaces is finished and installed, we do a thorough quality review. Every seam at the base and wall corners are caulked with mold-resistant silicone caulk. We review with you the completed project and confirm everything meets your expectations.
