What every ParagonCA conversion includes
The scope that makes the difference.
Drain & waterproofing
The shower floor is correctly sloped, tied into the drain assembly, and protected by a continuous waterproofing membrane. This is where most conversions fail. We do not rush it.
Custom tile shower
Tile is installed over a properly prepared substrate. Wall, floor, niche, and transitions are treated as one system — not patched together. You choose the tile; we make it last.
Fixtures, glass & finish
We install the valve, trim, shower fixtures, and frameless glass enclosure after the wet-area work is complete and inspected. Curbless and ADA-compliant designs available.
Behind the tile
Why conversions fail
Wrong drain slope
A shower floor that does not move water to the drain leaves standing water, stresses grout, and creates a long-term maintenance problem.
What we do instead: We form and verify the floor slope before waterproofing and tile begin.
Skipped waterproofing membrane
Tile and grout are not waterproof. Without a complete membrane, water reaches the substrate and framing behind the finish.
What we do instead: We waterproof walls, floor, corners, curb or threshold, drain connection, niche, and penetrations as one system.
Improper substrate
Tile set over weak, uneven, or moisture-sensitive backing eventually moves, cracks, or fails.
What we do instead: We remove compromised materials and build a stable tile substrate designed for a wet environment.

What Central Valley homeowners say
Real conversions. Real results.
“They explained the drain and waterproofing work before talking about tile. The finished shower is clean, solid, and exactly what we needed.”
M. R.
Modesto, CA
“We replaced an unused tub with a walk-in shower. The crew kept the scope clear and the bathroom was put back together the right way.”
J. and L. T.
Tracy, CA
“The difference was in the preparation. They removed what was failing, fixed the base, and did not cover problems up.”
K. S.
Turlock, CA
“We had a tub nobody used for ten years. ParagonCA turned it into a curbless shower my mother can actually use safely. The tile work is beautiful.”
R. and D. M.
Stockton, CA
“From the first walkthrough to the final inspection, every person on the crew treated our home with respect. The shower is exactly what we pictured.”
C. T.

Conversion questions
Tub-to-shower conversion FAQ
How much does a tub-to-shower conversion cost?
Our conversions start at $15,600. Final cost depends on shower size, tile, glass, fixture selection, and whether plumbing must move.
How long does a tub-to-shower conversion take?
The schedule depends on the scope, material availability, and conditions found after demolition. We provide a project schedule with the written scope.
Can I keep the tub in another bathroom?
Yes. Many homeowners convert only one tub, often in the primary bath, while keeping a tub elsewhere in the home.
Do I need a permit for a tub-to-shower conversion?
Permit requirements depend on the jurisdiction and whether plumbing, electrical, or structural work is involved. We confirm the applicable requirements during planning.
Can the shower drain be relocated?
Yes, when the existing framing and plumbing layout allow it. Drain relocation affects the scope because the floor and plumbing must be opened and rebuilt correctly.
How long does it take to replace a tub with a shower?
A straightforward conversion can move faster than a full bathroom remodel, but the work still requires proper demolition, plumbing, waterproofing, tile, cure time, and installation.
Can you build a walk-in shower conversion?
Yes. We can plan a walk-in shower with the appropriate threshold or a curbless configuration when the structure and drainage conditions support it.
What makes your waterproofing process different?
We treat the shower as a complete system: substrate, slope, membrane, corners, drain connection, niche, and every penetration are installed in the correct sequence before tile.
