Thinking About a Tub to Shower Conversion? Here's What You Should Know

Let's get started to find out whether a tub to shower conversion is the right move for your space.
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 plumbing fixtures — is removed and replaced with a custom-fitted shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you want to expand the shower's square footage beyond the original tub's position.
On a technical level, the work involves disconnecting the existing tub drain and supply lines, lifting the tub shell and any surrounding wall material that was tied to it, then constructing the new shower base with a proper slope toward the drain. New waterproof liner is installed before any surface covering goes in. Plumbing is adjusted to accommodate the new showerhead location and any additional fixtures you choose.
The finished product is a fully waterproofed shower that functions properly for many years. A tub to shower conversion done right is not just a surface-level change — it is a complete improvement to your bathroom's plumbing, waterproofing, and layout.

New cement board or tile backer is screwed to the wall studs, and a full waterproofing membrane is rolled or troweled on across every area that will contact water. The shower pan is sloped correctly to avoid standing water.

- Hanging Doors, Glass, or Hardware — Depending on your selected style, we mount your chosen enclosure system. Every mounting bracket is secured correctly to prevent loosening over time.
- Final Inspection, Grouting, and Caulking — Once the full shower is complete, we perform a room-by-room final inspection. Every seam at the perimeter are caulked with professional-grade caulk. We show you the completed project and make sure everything looks and functions as planned.
