What Really Is a Tub to Shower Conversion?

A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its surround and hardware — is removed and replaced with a professionally installed shower unit. The scope of the project depends on your existing bathroom footprint, your style choices, and whether you want to expand the shower's square footage beyond the original tub's location.

On a structural level, the project involves rerouting the existing tub drain and supply lines, taking out the tub unit and any tile, drywall, or backer board that was tied to it, then constructing the new shower base with a correct slope toward the center drain. New waterproof liner is laid down before any surface covering goes up. Plumbing is rerouted to accommodate the new showerhead location and any extra spray features you select.

The result is a code-compliant shower that drains correctly for decades. A tub to shower conversion done correctly is not just a surface-level change — it is a thorough improvement to your bathroom's plumbing, waterproofing, and layout.
