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 framing and plumbing fixtures — is taken out and replaced with a custom-fitted shower unit. The scope of the project varies based on your existing bathroom footprint, your style choices, and whether you plan to expand the shower's square footage beyond the original tub's location.
On a structural level, the process involves capping the existing tub drain and supply lines, taking out the tub shell and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a correct slope toward the shower drain. New waterproofing membrane is laid down before any tile, stone, or prefab panel goes in. Plumbing is adjusted to fit the new showerhead position and any additional fixtures you add.
The result is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a fundamental improvement to your bathroom's plumbing, waterproofing, and layout.
