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 enclosure and hardware — is removed and replaced with a professionally installed shower unit. The complexity of the project is shaped by your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's position.
On a technical level, the process involves rerouting the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then constructing the new shower pan with a code-compliant slope toward the drain. New waterproof liner is applied before any finish material goes in. Plumbing is rerouted to accommodate the new showerhead location and any additional fixtures you add.
The finished product is a fully waterproofed shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a cosmetic change — it is a fundamental upgrade to your bathroom's plumbing, waterproofing, and layout.

The shower pan is sloped correctly to avoid standing water.

- Glass Enclosure, Door, or Curtain Rod Installation — Depending on your design choice, we hang your shower door or curtain hardware. All hardware is secured correctly to provide a solid, long-lasting result.
- Completion Walk-Through and Finishing Touches — Once everything is complete, we do a careful quality review. Each transition joint at the base and wall corners are finished with flexible waterproof sealant. We walk you through the completed project and make sure everything is exactly what you wanted.
