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 enclosure and plumbing fixtures — is removed and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom footprint, your style choices, and whether you need to expand the shower's footprint beyond the original tub's position.

On a mechanical level, the process involves disconnecting the existing tub drain and supply lines, taking out the tub shell and any surrounding wall material that was tied to it, then framing the new shower floor with a proper slope toward the drain. New waterproof liner is installed before any surface covering goes up. Plumbing is adjusted to fit the new showerhead height and any extra spray features you choose.

The outcome is a code-compliant shower that functions properly for the long term. A tub to shower conversion done right is not just a cosmetic change — it is a thorough improvement to your bathroom's structure and usability.

6. Installing the Shower Enclosure — Depending on your selected style, we install your chosen enclosure system. Every mounting bracket is anchored properly to ensure years of smooth, wobble-free operation.
7. Completion Walk-Through and Finishing Touches — Once all surfaces is finished and installed, we do a room-by-room quality review. All caulk joints at the perimeter are sealed with flexible waterproof sealant. We show you the finished shower and make sure everything is exactly what you wanted.
