What Exactly Is a Tub to Shower Conversion?

The scope of the project depends on your existing bathroom plumbing configuration, your finish selections, and whether you plan to expand the shower's usable area beyond the original tub's location.
On a technical level, the work involves capping the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then framing the new shower base with a code-compliant slope toward the drain. New waterproofing membrane is installed before any surface covering goes in. Plumbing is adjusted to accommodate the new showerhead height and any extra spray features you select.
The outcome is a code-compliant check here shower that functions properly for many years. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.

- Custom Design Options — From subway tile surrounds to frameless glass doors, a tub to shower conversion unlocks significantly broader design directions than a prefab tub kit.

The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A member of our team meets with you on-site to assess your existing fixtures and framing. We review your goals, design preferences, and budget so the proposal aligns with exactly what you have in mind.
- Demolition and Removal — The existing fixtures and surrounding structure are carefully removed. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to make room for the updated fixture configuration.
- Building the Shower's Foundation — This is arguably the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the framing, and a full waterproofing membrane is applied across all wet surfaces. The shower pan is sloped correctly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew position the new plumbing fixtures according to your design plan. Whether you chose 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 apply your preferred wall and floor covering using the correct adhesive and grout system. Every seam is grouted and inspected before the enclosure goes in.
- Hanging Doors, Glass, or Hardware — Depending on your selected style, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is anchored properly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once all surfaces is complete, we do a room-by-room quality review. All caulk joints at corners and the floor-to-wall transition are finished with mold-resistant silicone caulk. We show you the final result and make sure everything is exactly what you wanted.
