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 enclosure and plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project depends on your existing bathroom layout, your finish selections, and whether you want to expand the shower's square footage beyond the original tub's location.
On a technical level, the process involves capping the existing tub drain and supply lines, removing the tub itself and any old tile surround that was tied to it, then constructing the new shower base with a code-compliant slope toward the shower drain. New waterproof liner is laid down before any surface covering goes on. Plumbing is adjusted to fit the new showerhead location and any extra spray features you choose.
The finished product is a structurally sound shower that drains correctly for decades. A tub to shower conversion done correctly is not just a cosmetic change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.
