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 enclosure and drain assembly — is removed and replaced with a professionally installed shower unit. The scale of the project depends on your existing bathroom layout, your style choices, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a structural level, the process involves rerouting the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then building out the new shower pan with a code-compliant slope toward the shower drain. New waterproof liner is installed before any finish material goes in. Plumbing is adjusted to serve the new showerhead location and any body sprays, handheld wands, or rain heads you add.
The outcome is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done correctly is not just a visual change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Process Step by Step
- Project Assessment and Design — A member of our team meets with you on-site to assess your existing space and infrastructure. We review your goals, design preferences, and budget so the project plan reflects exactly what you want.
- Tub Extraction and Teardown — The existing tub unit and wall material are demolished and cleared. Supply and drain lines tied to the old tub are properly shut off to prepare for the new shower plumbing layout.
- Structural Prep and Moisture Barrier Installation — This is often the most important stage of a tub to shower conversion. New waterproof backer material is screwed to the framing, and a continuous waterproof layer is installed across all wet surfaces. The floor base is graded toward the drain to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Licensed plumbers or our experienced crew set the new plumbing fixtures according to your fixture selections. Whether you selected a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this stage.
- Tile, Stone, or Panel Installation — Tile setters set your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every tile edge is grouted and checked before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we mount your chosen enclosure system. Every mounting bracket is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once everything is complete, we conduct a room-by-room final inspection. All caulk joints at corners and the floor-to-wall transition are sealed with flexible waterproof sealant. We walk you through the finished shower and confirm everything is exactly what you wanted.
