What Really 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 removed and replaced with a purpose-built shower unit. The scale of the project depends on your existing bathroom layout, your style choices, and whether you need to expand the shower's footprint beyond the original tub's location.
On a technical level, the project involves capping the existing tub drain and supply lines, taking out the tub unit and any surrounding wall material that was tied to it, then framing the new shower pan with a proper slope toward the center drain. New waterproofing membrane is laid down before any surface covering goes up. Plumbing is rerouted to fit the new showerhead location and any extra spray features you select.
The outcome is a structurally sound shower that functions properly for decades. A tub to shower conversion done correctly is not just a visual change — it is a thorough upgrade to your bathroom's plumbing, waterproofing, and layout.
