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 enclosure and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The complexity of the project depends on your existing bathroom footprint, your design preferences, and whether you plan to expand the shower's footprint beyond the original tub's space.
On a structural level, the work involves capping the existing tub drain and supply lines, lifting the tub shell and any surrounding wall material that was tied to it, then framing the new shower floor with a correct slope toward the shower drain. New waterproof liner is laid down before any finish material goes up. Plumbing is rerouted to serve the new showerhead location and any additional fixtures you choose.
The result is a fully waterproofed shower that functions properly for the long term. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough improvement to your bathroom's structure and usability.
