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 purpose-built shower unit. The complexity of the project varies based on your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's location.
On a structural level, the work involves rerouting the existing tub drain and supply lines, taking out the tub itself and any surrounding wall material that was tied to it, then constructing the new shower base with a correct slope toward the shower drain. New waterproof liner is installed before any finish material goes in. Plumbing is adjusted to accommodate the new showerhead height and any additional fixtures you add.
The result is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done right is not just a surface-level change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.

- Structural Prep and Moisture Barrier Installation — This is often the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is attached to the wall studs, and a full waterproofing membrane is installed across the shower floor and lower walls. The shower pan is graded toward the drain to ensure drainage.

Each transition joint at the perimeter are sealed with professional-grade caulk. We show you the completed project and verify everything looks and functions as planned.
