What Actually Is a Tub to Shower Conversion?

A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its enclosure and drain assembly — is demolished and replaced with a purpose-built shower unit. The scope of the project depends on your existing bathroom footprint, your style choices, and whether you need to expand the shower's usable area beyond the original tub's position.

On a technical level, the project involves rerouting the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then constructing the new shower floor with a proper slope toward the shower drain. New waterproofing membrane is laid down before any finish material goes on. Plumbing is modified to accommodate the new showerhead height and any additional fixtures you choose.

The outcome is a structurally sound shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a visual change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Project Step by Step

2. Demolition and Removal — 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 make room for the revised drain placement.
3. Building the Shower's Foundation — This is arguably the most important stage of a tub to shower conversion. New cement board or tile backer is fastened to the framing, and a industry-standard moisture barrier is applied across the shower floor and lower walls. The shower pan is pitched properly to ensure drainage.
4. Setting Valves, Drains, and Supply Lines — Our plumbing team position 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 roughed in at this phase.
5. Tile, Stone, or Panel Installation — Tile setters install your selected finish material using appropriate mortar, grout, and setting materials. Every grout joint is grouted and reviewed before glass or curtain hardware is installed.
6. Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we mount your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. All hardware is anchored properly to prevent loosening over time.
7. Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we conduct a room-by-room walk-through. All caulk joints at the perimeter are caulked with flexible waterproof sealant. We walk you through the final result and confirm everything is exactly what you wanted.
