Thinking About a Tub to Shower Conversion? Here's What You Should Know
A thoughtfully designed tub to shower conversion can fundamentally transform how you use your bathroom every single day.

Let's get started to find out whether a tub to shower conversion is the right move for your space.
What Exactly 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 drain assembly — is removed and replaced with a purpose-built shower unit. The scope of the project is shaped by your existing bathroom plumbing configuration, your finish selections, and whether you want to expand the shower's footprint beyond the original tub's location.
On a structural level, the work involves rerouting the existing tub drain and supply lines, lifting the tub shell and any tile, drywall, or backer board that was tied to it, then framing the new shower base with a correct slope toward the shower drain. New waterproof liner is installed before any finish material goes up. Plumbing is adjusted to accommodate the new showerhead height and any body sprays, handheld wands, or rain heads you choose.
The result is a code-compliant shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
