What Actually 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 hardware — is demolished and replaced with a professionally installed shower unit. The scope of the project depends on your existing bathroom layout, your design preferences, and whether you want to expand the shower's footprint beyond the original tub's position.

New waterproof liner is applied before any finish material goes in. Plumbing is rerouted to accommodate the new showerhead location and any body sprays, handheld wands, or rain heads you select.
The finished product is a fully waterproofed shower that performs reliably for the long term. A tub to shower conversion done correctly is not just a visual change — it is a fundamental upgrade to your bathroom's structure and usability.
