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 enclosure and plumbing fixtures — is taken out and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's usable area beyond the original tub's position.
On a mechanical level, the project involves rerouting the existing tub drain and supply lines, removing the tub unit and any surrounding wall material that was tied to it, then building out the new shower floor with a code-compliant slope toward the drain. New moisture barrier is applied before any surface covering goes on. Plumbing is adjusted to accommodate the new showerhead location and any additional fixtures you select.
The outcome is a code-compliant shower that performs reliably for decades. A tub to shower conversion done right is not just a surface-level change — it is a complete transformation to your bathroom's structure and usability.
