What Exactly 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 drain assembly — is removed and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's square footage beyond the original tub's position.
On a technical level, the process involves rerouting the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then framing the new shower base with a proper slope toward the center drain. New waterproof liner is laid down before any finish material goes in. Plumbing is rerouted to serve the new showerhead position and any body sprays, handheld wands, or rain heads you choose.
The finished product is a code-compliant shower that performs reliably for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.
