What Really 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 hardware — is removed and replaced with a custom-fitted shower unit. The scope of the project depends on your existing bathroom footprint, your design preferences, and whether you want to expand the shower's footprint beyond the original tub's location.
On a mechanical level, the process involves rerouting the existing tub drain and supply lines, removing the tub unit and any surrounding wall material that was tied to it, then constructing the new shower pan with a code-compliant slope toward the center drain. New waterproofing membrane is installed before any surface covering goes on. Plumbing is adjusted to accommodate the new showerhead location and any extra spray features you select.
The outcome is a code-compliant shower that drains correctly 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.
