What Really 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 taken out and replaced with a professionally installed shower unit. The complexity of the project varies based on your existing bathroom plumbing configuration, your finish selections, and whether you want 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 unit and any surrounding wall material that was tied to it, then framing the new shower base with a proper slope toward the center drain. New moisture barrier is installed before any tile, stone, or prefab panel goes in. Plumbing is modified to serve the new showerhead height and any extra spray features you choose.
The result is a code-compliant shower that performs reliably for decades. A tub to shower conversion done right is not just a surface-level change — it is a fundamental upgrade to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion

- Higher Resale Value — Updated bathrooms always show up among the highest-ROI upgrades for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
- Easier Cleaning — Shower pans, walls, and glass enclosures are often simpler to keep spotless than a full-length bathtub with a surrounding tile enclosure.
- Tailored Aesthetic Selections — From large-format porcelain tiles to frameless glass doors, a tub to shower conversion unlocks many more design possibilities than a prefab tub kit.

The Tub to Shower Conversion Project Step by Step
- In-Home Evaluation and Scope Review — A project consultant comes to your bathroom to measure your existing space and infrastructure. We discuss your must-haves and finish choices so the scope of work reflects exactly what you need.
- Demolition and Removal — The existing fixtures and surrounding structure are demolished and cleared. Existing water supply tied to the old tub are disconnected, capped, or rerouted to set the stage for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is widely considered the most important stage of a tub to shower conversion. New moisture-resistant substrate is fastened to the framing, and a full waterproofing membrane is applied across all wet surfaces. The drain area is pitched properly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Our plumbing team install the new rough-in plumbing according to your design plan. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is installed at this phase.
- Tile, Stone, or Panel Installation — Skilled installers apply your chosen wall tile, floor tile, or solid surface panels using appropriate mortar, grout, and setting materials. Every tile edge is sealed and inspected before moving to the next phase.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your preference, we hang your shower door or curtain hardware. Each component is anchored properly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once all surfaces is finished and installed, we conduct a room-by-room walk-through. Every seam at the base and wall corners are sealed with mold-resistant silicone caulk. We review with you the finished shower and verify everything looks and functions as planned.
