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 surround and hardware — is removed and replaced with a purpose-built shower unit. The scope of the project depends on your existing bathroom layout, your finish selections, and whether you plan to expand the shower's square footage beyond the original tub's position.
On a technical level, the project involves disconnecting the existing tub drain and supply lines, lifting the tub shell and any old tile surround that was tied to it, then building out the new shower pan with a code-compliant slope toward the center drain. New moisture barrier is applied before any tile, stone, or prefab panel goes up. Plumbing is modified to serve the new showerhead position and any extra spray features you choose.
The finished product is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a complete upgrade to your bathroom's infrastructure and finish.
Major Benefits of a Tub to Shower Conversion

- Better Return on Investment — Updated bathrooms consistently rank among the most valued renovations for resale. A tub to shower conversion tells buyers the home has been maintained to prospective buyers.
- Easier Cleaning — Shower pans, walls, and glass enclosures are often simpler to keep spotless than a full-length bathtub with hard-to-reach corners.
- Custom Design Options — From natural stone slabs to heavy-duty shower curtain systems, a tub to shower conversion creates room for many more design directions than a prefab tub kit.
- Lower Utility Bills — Running a full bath consumes roughly 30 to 50 gallons of water per bath. A low-flow showerhead installed during a tub to shower conversion can lower usage to under 20 gallons per shower.

The Tub to Shower Conversion Procedure Step by Step
- Initial Consultation and Planning — A member of our team visits your home to evaluate your existing tub, plumbing, and bathroom layout. We go over your must-haves and finish choices so the project plan matches exactly what you have in mind.
- Tub Extraction and Teardown — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Any plumbing connections tied to the old tub are disconnected, capped, or rerouted to prepare for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New cement board or tile backer is screwed to the framing, and a continuous waterproof layer is applied across every area that will contact water. The shower pan is sloped correctly to prevent pooling.
- Installing New Shower Plumbing — Licensed plumbers or our experienced crew position the new rough-in plumbing according to your fixture selections. Whether you went with 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 install your preferred wall and floor covering using the correct adhesive and grout system. Every tile edge is finished and checked before the enclosure goes in.
- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we hang your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once all surfaces is complete, we perform a thorough walk-through. Each transition joint at the perimeter are finished with flexible waterproof sealant. We review with you the final result and confirm everything is exactly what you wanted.
