Bathroom Remodeling in Shreveport, LA

Professional Plumbing Rough-In & Fixture Installation for Your Remodel

A successful bathroom remodel depends on the plumbing behind the walls as much as the tile and paint you see every day. Mark Johnson & Sons Plumbing handles the complete plumbing scope for bathroom renovations throughout Shreveport — from relocating supply and drain lines to installing your final fixtures with precision. As part of our comprehensive plumbing services in Shreveport, we deliver professional results backed by decades of experience.

Why Bathroom Remodeling Plumbing Matters

The plumbing phase of a bathroom remodel is where most projects succeed or fail. Moving a toilet, relocating a shower, or adding a double vanity all require changes to supply lines, drain routing, and venting that must comply with the Louisiana State Plumbing Code. Shortcuts here create leaks, code violations, and costly callbacks that delay your project by weeks.

Shreveport homes span every era of construction, from pre-war bungalows in Broadmoor to newer builds in Southern Trace. Each generation used different pipe materials — galvanized steel, cast iron, copper, CPVC, and PEX — and each presents unique challenges when tying new plumbing into existing systems. A licensed plumber who understands these transitions prevents compatibility failures that a general contractor may overlook.

Moisture control is especially critical in Northern Louisiana, where summer humidity regularly exceeds 80 percent. Properly sealed connections, adequate venting, and correct drain slope ensure your newly remodeled bathroom does not develop hidden moisture problems within its first year.

Our Bathroom Remodeling Services

Plumbing Rough-In

We install all supply lines, drain lines, and vent stacks before your walls are closed. This includes precise placement of stub-outs for sinks, toilets, showers, and tubs according to your remodel layout. We coordinate with your general contractor on timing and access.

Fixture Installation

Once your tile, flooring, and cabinetry are complete, we return for final fixture connections. Faucets, toilets, showerheads, tub fillers, and accessories are mounted, connected, tested, and adjusted for proper operation.

Layout Changes

Relocating a toilet, moving a vanity to a different wall, or converting a tub to a walk-in shower all require rerouting drain and supply lines. We assess the structural and plumbing implications of your proposed layout and execute the changes to code.

Accessibility Modifications

Walk-in showers with zero-threshold entries, ADA-compliant grab bar backing, comfort-height toilet installations, and handheld showerhead conversions. We help Shreveport homeowners age in place or accommodate family members with mobility needs.

Pipe Upgrades

If your remodel opens walls that contain aging galvanized or polybutylene piping, we can replace those sections with modern PEX or copper while the walls are accessible. This is the most cost-effective time to address old pipe materials.

Water Heater Assessment

A bathroom addition or major upgrade may exceed your current water heater’s capacity. We evaluate whether your existing unit can support the new demand or recommend an upgrade before your remodel is complete.

Frequently Asked Questions

Do I need a permit for bathroom remodeling plumbing in Shreveport?

Any work that involves moving, adding, or replacing drain, waste, or vent piping typically requires a plumbing permit in Shreveport. Simple fixture replacements in the same location generally do not. We advise on permit requirements for your specific project scope.

Can you move a toilet to a different wall?

Yes, though it requires extending or rerouting the drain line and may involve cutting into the subfloor. We assess the feasibility based on your home’s floor structure and existing drain routing before providing a quote.

How long does the plumbing phase of a remodel take?

Rough-in typically takes one to two days depending on scope. Final fixture installation usually takes a half day to a full day. Complex layout changes or pipe replacements extend the timeline, which we outline in your project quote.

Should I replace old pipes during my remodel?

If your walls are already open and the existing pipes are galvanized steel, polybutylene, or showing signs of corrosion, replacing them during the remodel saves significant labor cost compared to addressing them later.

Can you handle just the plumbing, or do you do the entire remodel?

We specialize in the plumbing scope — rough-in, pipe work, and fixture installation. We work alongside your general contractor, tile installer, and other trades. We do not perform carpentry, tiling, or electrical work.

What accessibility modifications do you offer?

We install curbless shower drains, comfort-height toilets (17-19 inch seat height), thermostatic mixing valves to prevent scalding, and supply connections for wall-mounted sinks and grab bar reinforcement.

How do I know if my water heater can handle a bathroom upgrade?

As a guideline, a standard 40-gallon tank serves two to three bathrooms adequately. Adding a large soaking tub, multiple showerheads, or a new bathroom to your home may push demand beyond your current unit’s recovery rate. We evaluate capacity as part of our remodel assessment.

Do you coordinate directly with my general contractor?

Yes. We communicate directly with your GC on scheduling, rough-in requirements, and inspection timing. Clear coordination between trades is essential to keeping your remodel on schedule.

What happens if unexpected plumbing issues are found during demolition?

Remodels in older Shreveport homes frequently reveal surprises — corroded fittings, improper venting, or non-code drain routing. We assess the situation, explain the options and costs, and proceed only with your approval.

Can I supply my own fixtures for you to install?

Absolutely. We install customer-purchased fixtures regularly. We recommend confirming compatibility with your plumbing configuration before ordering — send us the model numbers and we will verify fit.
