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 surround and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scale 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 location.
On a mechanical level, the project involves capping the existing tub drain and supply lines, removing the tub shell and any old tile surround that was tied to it, then constructing the new shower pan with a code-compliant slope toward the center drain. New waterproof liner is installed before any surface covering goes on. Plumbing is rerouted to fit the new showerhead position and any extra spray features you choose.
The result is a structurally sound shower that drains correctly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
