What Exactly 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 custom-fitted shower unit. The scale of the project is shaped by your existing bathroom footprint, your style choices, and whether you want to expand the shower's footprint beyond the original tub's space.
On a structural level, the work involves rerouting the existing tub drain and supply lines, removing the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower floor with a correct slope toward the center drain. New moisture barrier is laid down before any tile, stone, or prefab panel goes in. Plumbing is rerouted to fit the new showerhead location and any additional fixtures you add.
The outcome is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a thorough upgrade to your bathroom's structure and usability.

- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are properly shut off to make room for the revised drain placement.

New moisture-resistant substrate is screwed to the wall studs, and a industry-standard moisture barrier is installed across the shower floor and lower walls. The floor base is pitched properly to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Licensed plumbers or our experienced crew position the new shower valve, drain body, and supply lines 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 roughed in at this stage.

- Final Inspection, Grouting, and Caulking — Once all surfaces is finished and installed, we conduct a room-by-room quality review. Every seam at the perimeter are sealed with flexible waterproof sealant. We review with you the final result and verify everything looks and functions as planned.
