What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and plumbing fixtures — is taken out and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's space.
On a technical level, the project involves rerouting the existing tub drain and supply lines, removing the tub itself and any surrounding wall material that was tied to it, then framing the new shower base with a code-compliant slope toward the drain. New waterproof liner is laid down before any finish material goes in. Plumbing is adjusted to serve the new showerhead position and any extra spray features you add.
The outcome is a structurally sound shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.

- Quality Check and Project Sign-Off — Once everything is complete, we perform a thorough walk-through. Every seam at the base and wall corners are sealed with professional-grade caulk. We walk you through the completed project and verify everything looks and functions as planned.
