What Actually Is a Tub to Shower Conversion?

The scope of the project depends on your existing bathroom layout, read more your design preferences, and whether you plan to expand the shower's usable area beyond the original tub's space.
On a technical level, the process 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 base with a proper slope toward the center drain. New waterproof liner is laid down before any tile, stone, or prefab panel goes in. Plumbing is adjusted to serve the new showerhead position and any additional fixtures you select.
The finished product is a code-compliant shower that performs reliably for many years. A tub to shower conversion done right is not just a surface-level change — it is a fundamental improvement to your bathroom's infrastructure and finish.

The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A member of our team visits your home to assess your existing tub, plumbing, and bathroom layout. We review your wishlist and timeline so the project plan matches exactly what you have in mind.
- Tub Extraction and Teardown — The existing tub unit and wall material are taken out. Supply and drain lines tied to the old tub are professionally handled to set the stage for the revised drain placement.
- Structural Prep and Moisture Barrier Installation — This is often the most important stage of a tub to shower conversion. New waterproof backer material is attached to the wall studs, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The floor base is sloped correctly to prevent pooling.
- Setting Valves, Drains, and Supply Lines — Our plumbing team set the new rough-in plumbing according to your fixture selections. Whether you went with a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this phase.
- Finishing the Shower Walls and Floor — Skilled installers install your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every tile edge is grouted and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your preference, we hang your shower door or curtain hardware. Each component is anchored properly to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once the full shower is tiled, grouted, and enclosed, we do a careful final inspection. Every seam at the base and wall corners are caulked with mold-resistant silicone caulk. We review with you the final result and make sure everything looks and functions as planned.
