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 demolished 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 plan to expand the shower's square footage beyond the original tub's position.
On a technical level, the work involves rerouting the existing tub drain and supply lines, taking out the tub itself and any old tile surround that was tied to it, then constructing the new shower floor with a correct slope toward the drain. New waterproof liner is installed before any finish material goes on. Plumbing is rerouted to serve the new showerhead position and any additional fixtures you choose.
The finished product is a code-compliant shower that functions properly for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete upgrade to your bathroom's plumbing, waterproofing, and layout.

The floor base is sloped correctly to avoid standing water.
