What Exactly Is a Tub to Shower Conversion?
A tub to shower conversion is a home renovation service in which an existing bathtub — along with its framing and drain assembly — is demolished and replaced with a purpose-built shower unit. The complexity of the project varies based on your existing bathroom layout, your style choices, and whether you need to expand the shower's square footage beyond the original tub's space.
On a technical level, the process involves disconnecting the existing tub drain and supply lines, lifting the tub unit and any surrounding wall material that was tied to it, then building out the new shower floor with a proper slope toward the drain. New waterproof liner is laid down before any surface covering goes on. Plumbing is adjusted to serve the new showerhead location and any additional fixtures you choose.
The finished product is a code-compliant shower that performs reliably for the long term. A tub to shower conversion done by experienced hands is not just a cosmetic change — it is a fundamental improvement to your bathroom's plumbing, waterproofing, and layout.

- Building the Shower's Foundation — This is often the most important stage of a tub to shower conversion. New cement board or tile backer is attached to the structural framing, and a full waterproofing membrane is applied across the shower floor and lower walls. The floor base is graded toward the drain to avoid standing water.
- Setting Valves, Drains, and Supply Lines — Our plumbing team position the new plumbing fixtures according to your fixture selections. Whether you chose a single overhead rain head, a handheld wand, or a multi-function valve system, everything is roughed in at this point.
- Applying Your Chosen Finish Materials — Tile setters apply your preferred wall and floor covering using the correct adhesive and grout system. Every seam is sealed and checked before moving to the next phase.

- Quality Check and Project Sign-Off — Once the full shower is finished and installed, we do a room-by-room quality review. All caulk joints at the perimeter are sealed with flexible waterproof sealant. We walk you through the final result and verify everything is exactly what you wanted.
