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 surround and hardware — is demolished and replaced with a custom-fitted shower unit. The complexity of the project is shaped by your existing bathroom layout, your design preferences, and whether you need to expand the shower's usable area beyond the original tub's position.
On a structural level, the project involves capping 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 drain. New moisture barrier is laid down before any surface covering goes up. Plumbing is adjusted to fit the new showerhead position and any body sprays, handheld wands, or rain heads you select.
The result is a structurally sound shower that functions properly for many years. A tub to shower conversion done right is not just a visual change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.

- Lower Maintenance Demands — Shower pans, walls, and glass enclosures are typically faster to scrub and wipe down than a standard bathtub with a surrounding tile enclosure.

- Project Assessment and Design — A member of our team meets with you on-site to evaluate your existing space and infrastructure. We discuss your must-haves and finish choices so the project plan matches exactly what you have in mind.
- Removal of the Existing Tub and Surround — 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 updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is often the most critical stage of a tub to shower conversion. New moisture-resistant substrate is screwed to the wall studs, and a full waterproofing membrane is applied across all wet surfaces. The floor base is pitched properly to ensure drainage.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew set 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 phase.
- Applying Your Chosen Finish Materials — Tile setters install your selected finish material using professional-grade installation materials. Every tile edge is finished and checked before the enclosure goes in.
- Installing the Shower Enclosure — Depending on your selected style, we hang your shower door or curtain hardware. All hardware is anchored properly to provide a solid, long-lasting result.
- Final Inspection, Grouting, and Caulking — Once everything is tiled, grouted, and enclosed, we conduct a careful walk-through. All caulk joints at the perimeter are sealed with mold-resistant silicone caulk. We review with you the completed project and verify everything looks and functions as planned.
