What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its framing and plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your design preferences, and whether you want to expand the shower's square footage 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 constructing the new shower floor with a correct slope toward the center drain. New moisture barrier is applied before any tile, stone, or prefab panel goes in. Plumbing is adjusted to accommodate the new showerhead height and any body sprays, handheld wands, or rain heads you choose.
The result is a structurally sound shower that performs reliably for decades. A tub to shower conversion done right is not just a surface-level change — it is a complete improvement to your bathroom's structure and usability.
Key Benefits of a Tub to Shower Conversion

- Improved Accessibility — A tub to shower conversion can incorporate a barrier-free floor transition, grab bars, and a shower bench to assist homeowners with limited mobility.
- More Efficient Daily Bathing — Most people shower significantly more than they bathe. A tub to shower conversion aligns your bathroom with how you actually use it.
- Higher Resale Value — Updated bathrooms reliably appear among the top home improvements for resale. A tub to shower conversion communicates updated finishes to prospective buyers.
- Easier Cleaning — Shower surrounds and bases are typically faster to keep spotless than a deep-soaking bathtub with a surrounding tile enclosure.
- Custom Design Options — From large-format porcelain tiles to heavy-duty shower curtain systems, a tub to shower conversion unlocks many more design directions than a prefab tub kit.

- 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 must-haves and finish choices so the scope of work matches 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 professionally handled to prepare for the new shower plumbing layout.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is fastened to the wall studs, and a full waterproofing membrane is rolled or troweled on across all wet surfaces. The floor base is sloped correctly to ensure drainage.
- Plumbing Rough-In and Fixture Placement — Our plumbing team install the new rough-in plumbing according to your chosen layout. Whether you chose a basic or premium shower setup, everything is installed at this stage.
- Applying Your Chosen Finish Materials — Tile setters install your chosen wall tile, floor tile, or solid surface panels using professional-grade installation materials. Every grout joint is grouted and inspected before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Every mounting bracket is set into the tile or framing to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once the full shower is complete, we conduct a room-by-room walk-through. Each transition joint at the base and wall corners are sealed with mold-resistant silicone caulk. We review with you the finished shower and confirm everything meets your expectations.
