What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a bathroom remodeling service in which an existing bathtub — along with its surround and hardware — is demolished and replaced with a professionally installed shower unit. The scope of the project varies based on your existing bathroom plumbing configuration, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's space.
On a technical level, the project involves rerouting the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then building out the new shower floor with a correct slope toward the drain. New waterproofing membrane is installed before any finish material goes in. Plumbing is modified to fit the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The result is a code-compliant shower that drains correctly for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a fundamental improvement to your bathroom's infrastructure and finish.
