What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and plumbing fixtures — is taken out and replaced with a professionally installed shower unit. The scale of the project varies based on your existing bathroom footprint, your finish selections, and whether you need to expand the shower's usable area beyond the original tub's space.
On a technical level, the process 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 constructing the new shower floor with a correct slope toward the center drain. New waterproofing membrane is applied before any tile, stone, or prefab panel goes on. Plumbing is modified to accommodate the new showerhead location and any extra spray features you add.
The finished product is a fully waterproofed shower that functions properly for decades. A tub to shower conversion done right is not just a cosmetic change — it is a thorough transformation to your bathroom's structure and usability.
