What Really Is a Tub to Shower Conversion?

A tub to shower conversion is a home renovation service in which an existing bathtub — along with its enclosure and drain assembly — is taken out and replaced with a custom-fitted shower unit. The complexity of the project varies based on your existing bathroom layout, your finish selections, and whether you want to expand the shower's usable area beyond the original tub's space.

On a mechanical level, the work involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then building out the new shower base with a correct slope toward the center drain. New moisture barrier is laid down before any finish material goes in. Plumbing is adjusted to serve the new showerhead height and any extra spray features you select.

The finished product is a fully waterproofed shower that drains correctly for decades. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a thorough transformation to your bathroom's structure and usability.

The Tub to Shower Conversion Procedure Step by Step

1. Initial Consultation and Planning — A remodeling specialist meets with you on-site to assess your existing fixtures and framing. We go over your wishlist and timeline so the scope of work matches exactly what you want.
2. Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are carefully removed. Any plumbing connections tied to the old tub are properly shut off to make room for the revised drain placement.
3. Building the Shower's Foundation — This is widely considered the most critical stage of a tub to shower conversion. New cement board or tile backer is screwed to the framing, and a continuous waterproof layer is installed across every area that will contact water. The shower pan is pitched properly to prevent pooling.
4. Setting Valves, Drains, and Supply Lines — Our plumbing team set the new plumbing fixtures according to your chosen layout. Whether you went with a basic or premium shower setup, everything is installed at this point.
5. Finishing the Shower Walls and Floor — Skilled installers apply your chosen wall tile, floor tile, or solid surface panels using the correct adhesive and grout system. Every seam is grouted and reviewed before the enclosure goes in.
6. Glass Enclosure, Door, or Curtain Rod Installation — Depending on your selected style, we install your frameless glass door and panel, a semi-frameless swing door, or a curtain rod with rings. Each component is secured correctly to ensure years of smooth, wobble-free operation.
7. Completion Walk-Through and Finishing Touches — Once the full shower is complete, we do a room-by-room walk-through. All caulk joints at the base and wall corners are finished with flexible waterproof sealant. We walk you through the finished shower and verify everything meets your expectations.
