What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a professionally installed shower unit. The complexity of the project depends on your existing bathroom layout, your finish selections, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a structural level, the work involves rerouting the existing tub drain and supply lines, taking out the tub itself and any old tile surround that was tied to it, then framing the new shower pan with a proper slope toward the shower drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes up. Plumbing is rerouted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you choose.
The finished product is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete transformation to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion

The Tub to Shower Conversion Process Step by Step

- Tub Extraction and Teardown — The existing fixtures and surrounding structure are carefully removed. Existing water supply tied to the old tub are properly shut off to make room for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New waterproof backer material is screwed to the framing, and a full waterproofing membrane is rolled or troweled on across the shower floor and lower walls. The drain area is pitched properly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Our plumbing team install the new shower valve, drain body, and supply lines according to your fixture selections. Whether you went with a basic or premium shower setup, everything is positioned at this phase.
- Finishing the Shower Walls and Floor — Tile setters apply your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every tile edge is grouted and reviewed before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your chosen enclosure system. All hardware is secured correctly to ensure years of smooth, wobble-free operation.
- Final Inspection, Grouting, and Caulking — Once everything is complete, we conduct a careful walk-through. Every seam at the base and wall corners are sealed with flexible waterproof sealant. We show you the completed project and verify everything looks and functions as planned.
