Most bathtub-to-shower conversions in Nashville cost between $15,000 and $25,000.
That surprises a lot of homeowners—but once you understand what’s involved, it makes sense.
Why Is a Tub-to-Shower Conversion So Expensive?
This isn’t a simple fixture swap. You’re not just removing a tub and dropping in a shower.
You’re rebuilding the entire system behind it.
A properly built walk-in shower requires structural prep, plumbing changes, waterproofing, and detailed finish work—all of which drive cost.
What’s Included in a Typical Tub-to-Shower Conversion?
At BEC Innovations, a standard bathtub-to-walk-in-shower conversion typically includes:
- Selections assistance + demo prep: We help guide material selections and protect your home before work begins.
- Bathtub and surround removal + disposal: Full demolition of the existing tub and walls.
- Plumbing relocation: Shower drains are not in the same location as tub drains. We move plumbing to properly support the new layout.
- Full waterproofing system: This is one of the most critical (and often skipped) steps. A shower must be fully waterproofed behind the tile—not just “water-resistant.”
- Custom sloped shower floor: The floor is built and sloped on-site to direct water to the drain.
- Tile installation:
- Small format tile on the floor (~$6/sf) for proper drainage
- Medium format tile on the walls to the ceiling (~$4/sf)
- Upgraded shower valve + fixtures: Better functionality, longevity, and user experience.
- Tile and grout installation: Skilled labor that directly impacts how your shower performs long-term.
- Glass enclosure (standard, not frameless/custom): Even a basic glass surround is a meaningful cost component.
What Drives the Price Toward $25K?
Several factors can push your project toward the higher end of the range:
- Larger shower footprint
- More complex plumbing moves, or original plumbing that doesn’t easily integrate with newer plumbing systems
- Higher-end tile selections
- Structural or framing adjustments
- Upgraded fixtures or glass
- Water intrusion that affects the surrounding framing
Why Cheap Shower Conversions Fail
If you’re seeing significantly lower pricing, it’s usually because something is missing:
- Incomplete waterproofing
- No proper slope to the drain
- Lower-quality installation
- Shortcuts in prep work
These are the exact issues that lead to leaks, mold, and expensive repairs later.
The Bottom Line
A walk-in shower conversion is one of the best upgrades you can make to your bathroom—but only if it’s done correctly.
