BATHROOM REMODEL PLUMBING — DONE RIGHT, DONE ON TIME

Bathroom remodels are one of the highest-stakes plumbing jobs in residential work. Water lines, drain lines, vent stacks, valves, and fixtures all have to be installed correctly — because once the tile goes up and the drywall closes, any mistake means tearing that work back out. We work with homeowners doing their own remodel, general contractors, and designers on scopes ranging from a simple toilet and vanity swap up to full gut-and-remodel primary bath suites with standalone tubs and double shower heads.

What we typically handle on a bath remodel

1. Rough-in plumbing — new water lines to fixtures, new drain and vent piping where the layout changes, proper slope, cleanouts, and all connections meeting Louisiana plumbing code
2. Fixture installation — toilets, vanities with sinks, tubs, showers, bidets, handheld sprayers — any factory fixture with proper supply and drain connections
3. Shower valve install and replacement — Moen, Delta, Kohler, Grohe, Hansgrohe, TOTO, any brand, any configuration (single-handle, two-handle, thermostatic, pressure-balance)
4. Drain relocations — moving a toilet, shower, or sink drain to a new location requires proper subfloor work and vent routing
5. Shower pan and curb installation — pre-slope, liner or linear drain, waterproof membrane, ready for tile
6. Tub install or removal — clawfoot, alcove, drop-in, freestanding, Japanese soaking — all styles installed with proper drain, overflow, and supply
7. Permit coordination — we pull plumbing permits and schedule city inspections for rough-in and final
8. Repipe opportunity — while walls are open is the cheapest time to repipe galvanized or polybutylene runs in the bathroom

What we don't do (and who we partner with)

We're plumbers, not general contractors. For full gut-and-remodel projects we coordinate with your GC or designer. For homeowners DIY'ing the cosmetic work (tile, paint, cabinet install) we handle the plumbing rough-in, rough-in inspection, and final fixture install, then coordinate back with you on your schedule. We have trusted partner relationships with tile crews, drywall contractors, electricians, and designers across North Louisiana — happy to make referrals.

North Louisiana bathroom remodel considerations

Repiping opportunity — if your home has galvanized or polybutylene supply lines, the walls-open stage of a bath remodel is the single cheapest time to replace them. Adding a bathroom repipe to an already-open-wall job is often $1,200-$2,500 vs. $3,500-$5,500 as a standalone job. Almost always worth doing.

Water softener for new luxury fixtures — hard water is aggressive on high-end shower valves, rainfall heads, and glass shower enclosures. If you're investing $5,000 in a new shower with premium fixtures, a $2,500 water softener is a small additional line item that doubles the lifespan of everything in the bath.

Hot water capacity — standalone soaking tubs (70+ gallons) and multi-head showers can exceed your current water heater. If the remodel includes a big tub or multi-head shower, we spec the water heater upgrade during design to avoid a cold-shower surprise after the project's done.

Basement bathroom below sewer line — below-grade bathrooms need a sewage ejector pump to lift waste to the main sewer. This adds $1,850-$3,850 to a basement bath scope and needs to be planned during design.

What Mark Johnson & Sons does differently

Same plumber from rough-in through final. You're not getting a new crew every phase. Flat-rate pricing quoted in writing before work starts, with allowances for fixture upgrades clearly called out so you know what moves the number. Permits pulled, inspections scheduled, and 1-year workmanship warranty on all plumbing work. Most bath remodels we plumb run a rough-in visit (1-2 days), then final fixture install (1 day) once the cosmetic work is complete — scheduled around your GC's timeline.
