What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its surround and drain assembly — is demolished and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub itself and any old tile surround that was tied to it, then building out the new shower floor with a proper slope toward the shower drain. New waterproofing membrane is installed before any finish material goes in. Plumbing is modified to accommodate the new showerhead height read more and any body sprays, handheld wands, or rain heads you select.
The outcome is a structurally sound shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a thorough transformation to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant comes to your bathroom to assess your existing tub, plumbing, and bathroom layout. We review your must-haves and finish choices so the project plan reflects exactly what you have in mind.
- Demolition and Removal — The existing tub unit and wall material are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to make room for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the wall studs, and a industry-standard moisture barrier is rolled or troweled on across the shower floor and lower walls. The shower pan is sloped correctly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew install the new plumbing fixtures according to your chosen layout. Whether you selected a standard showerhead or an upgraded fixture package, everything is roughed in at this stage.
- Tile, Stone, or Panel Installation — Tile setters install your selected finish material using professional-grade installation materials. Every seam is finished and inspected before moving to the next phase.
- Installing the Shower Enclosure — Depending on your design choice, we hang your chosen enclosure system. All hardware is set into the tile or framing to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we do a careful quality review. Each transition joint at corners and the floor-to-wall transition are sealed with professional-grade caulk. We review with you the final result and confirm everything looks and functions as planned.
