Tub-to-Shower Conversion in Oklahoma City
A tub-to-shower conversion in Oklahoma City costs $7,500 to $13,500 and takes 4 to 7 working days from initial tear-out to ready-for-glass. Parsons Custom Bath and Shower removes outdated fiberglass or cast-iron bathtubs, converts narrow 1.5-inch drains to 2-inch DWV high-flow lines, fully seals the shower with Schluter-KERDI waterproofing, and builds a custom walk-in tile shower with a lifetime leakproof warranty.
The 5-Stage Tub-to-Shower Conversion Process
Rebuilding a shower enclosure to TCNA and Schluter standards requires zero shortcuts. Here is how Donnie builds every shower from the framing forward.
Tear-Out & 2" DWV Drain Conversion
We strip the space to bare studs and subfloor, inspecting for hidden water damage or bad framing. Standard tub drains use 1.5-inch piping. Code and performance require upgrading to a 2-inch PVC/ABS DWV drain line so high-flow showerheads drain instantly without backup.
Custom Tile vs. Franchise Acrylic Overlays
Many OKC homeowners are quoted $15,000 to $22,000 by national franchises for quick 1-day acrylic tub overlays. Compare the engineering behind a real custom tile conversion versus a plastic shell.
| Specification Factor | Parsons Custom Bath and Shower Custom Conversion | National Franchise Acrylic Overlay |
|---|---|---|
| Waterproofing Integrity | Schluter-KERDI 100% vapor-impermeable membrane sealed from studs to ceiling | Unsealed plastic panels glued over old drywall; traps moisture & mold behind shell |
| Plumbing & Drain Line | Full 2-inch DWV high-flow shower drain conversion to handle high volume | Forces connection to restrictive 1.5-inch tub drain; prone to pooling and backup |
| Niches & Seating | Custom recessed studs-out niches & benches capped with single-piece stone | Glue-on plastic corner caddies that yellow, crack, and break off over time |
| Door & Glass Prep | Laser-plumbed walls for seamless frameless heavy glass enclosure installation | Requires bulky aluminum tracks with rubber sweeps to cover out-of-plumb walls |
| Home Appraisal & Equity | Adds permanent custom home appraisal value & buyer appeal | Viewed by appraisers & buyers as a cheap temporary cover-up |
| Long-Term Warranty | Lifetime warranty on waterproofing when installed from studs out by Donnie | Limited prorated surface warranties with exclusions for discoloration or seals |

2" DWV Drain Conversion & Pre-Slope Mortar Bed
Standard bathtub drains use narrow 1.5-inch lines prone to sluggish pooling. Every Parsons conversion replaces the restricted line with a 2-inch DWV PVC line and a dry-pack mortar bed pitched at 1/4" per foot toward the bonding flange. Water drains instantly without standing.
Schluter-KERDI Waterproofing & Solid Quartz Curb Caps
We never glue plastic panels over drywall. The shower is sealed from subfloor to ceiling with Schluter-KERDI vapor-impermeable membrane and water-tested for 24 hours. Thresholds and niches are capped with single-piece solid quartz, eliminating grout joints on horizontal planes. Serving Oklahoma City, Deer Creek, Nichols Hills, and Edmond.
