Let's get started to learn whether a tub to shower conversion is the right move for your home.
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 drain assembly — is taken out and replaced with a purpose-built shower unit. The scale of the project varies based on your existing bathroom layout, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a mechanical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub unit and any old tile surround that was tied to it, then constructing the new shower base with a correct slope toward the shower drain. New waterproofing membrane is applied before any surface covering goes on. Plumbing is rerouted to accommodate the new showerhead height and any additional fixtures you choose.
The finished product is a code-compliant shower that performs reliably for decades. A tub to shower conversion done by experienced hands is not just a visual change — it is a fundamental transformation to your bathroom's plumbing, waterproofing, and layout.
Top Benefits of a Tub to Shower Conversion
