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 plumbing fixtures — is demolished and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom layout, your design preferences, and whether you want to expand the shower's square footage beyond the original tub's space.
On a mechanical level, the process involves capping the existing tub drain and supply lines, removing the tub unit and any old tile surround that was tied to it, then constructing the new shower base with a proper slope toward the drain. New waterproofing membrane is laid down before any surface covering goes up. Plumbing is adjusted to fit the new showerhead location and any additional fixtures you choose.
The result is a fully waterproofed shower that performs reliably for many years. A tub to shower conversion done correctly is not just a cosmetic change — it is a thorough upgrade to your bathroom's structure and usability.
