The Part of a Bathroom Remodel Nobody Sees

Tile and vanities get picked first. The pipes behind them decide what is actually possible. Where the drain sits is why a shower cannot always move to the other wall.

Global Remodeling Pros is a licensed general contractor working across Anne Arundel County. We run our own plumbing crew, so the same company that opens your wall closes it back up.

Bathroom plumbing is the stage that sits under every other part of our bathroom remodeling service in Arnold. It covers supply lines, drain and waste lines, vents, shutoff valves and the rough-in that all of it hangs on.

This page covers what that work includes and how far a fixture can really move. It also covers when old pipe should be replaced, and how county permits work.

What Bathroom Plumbing Work Covers in an Arnold Remodel

Bathroom plumbing in a remodel means three systems. Supply lines bring water in. Drain lines carry waste out. Vents let those drains breathe.

Setting all of it in the open wall is called the rough-in. Fixtures go on at the end. Get the rough-in right and the rest of the room lands on top of it.

Supply Lines

Hot and cold lines feed the sink, toilet, tub and shower. We run new line to each fixture and put a shutoff valve on it. One leak then never means shutting off the whole house.

Drain and Waste Lines

A toilet drains on a three inch line. Sinks, tubs and showers run smaller. Every drain needs a steady downhill fall to the stack, or water sits in the pipe and the fixture gurgles.

Vents

A drain only flows if air can follow it. Vent pipe ties each fixture back to the roof. Skipping it is why a slow sink keeps coming back after the line is snaked.

The Rough-In

With the walls open we set every line to the exact height and spacing the new fixtures need. This is the stage the county inspector signs off before any tile goes up.

We take photos of the open wall before it closes and hand them to you. If something has to be reached years from now, you know what is back there.

How Far You Can Move a Toilet, Sink or Shower

Almost any fixture can move. The real question is what it costs. The answer comes down to the drain, not the water line.

A Sink Is the Cheap One to Move

Sink drains are small and easy to reroute inside the wall. Sliding a vanity a few feet along the same wall is usually a short day for our plumber.

A Toilet Is the Expensive One

A toilet needs that wide drain, its own vent and a steady fall. Moving it more than a couple of feet often means opening the ceiling in the room below.

Tubs and Showers Follow the Floor

A tub or shower drain runs between the floor joists. If the new spot runs across the joists instead of beside them, the work grows. We cannot cut framing wherever we like.

A Slab Floor Changes the Answer

Some Arnold homes sit on a slab, with the drain lines buried in concrete. Moving a fixture there means cutting and patching the slab, so we price that differently from a joist floor.

We walk your bathroom, find the stack, and tell you which moves are simple and which ones add real money. Most homeowners change the plan once they hear it, while changing it is still free.

When Old Pipe in an Arnold Home Should Be Replaced

Open walls are the cheapest hour you will ever get for pipe work. Once tile is on, the same job costs several times more. So we look at what is back there before we close anything.

Galvanized Steel Supply Lines

Older Arnold bathrooms still run galvanized steel. It rusts closed from the inside, which is why pressure drops year after year. If we find it in the wall, we replace that run.

Polybutylene

Gray plastic supply line from the 1980s and 1990s fails without warning. We swap any of it we find while the wall is open. We show you the piece we pulled out.

Cast Iron Drain Lines

Cast iron drains can last a long time, but the bottom of the pipe rusts first. We look for scaling and soft spots, and tie new line into sound pipe only.

Valves, Traps and the Flange

Old shutoff valves seize and weep. Toilet flanges crack and sit low after a new floor goes down. These are small parts that cause most call backs, so they get replaced, not reused.

Water damage shows up at this stage too. Soft subfloor near a tub or a toilet gets priced and repaired before the new work goes over it.

Permits and Inspections for Bathroom Plumbing in Anne Arundel County

Plumbing work gets inspected for a reason. A hidden leak or a bad vent is found years later, usually by the ceiling below it.

What Needs a Permit

Moving or adding a drain, a vent or a supply line needs a plumbing permit from Anne Arundel County. Swapping a faucet or a toilet in place usually does not.

The Rough-In Inspection

The inspector comes while the walls are still open, checks the lines, the fall and the vents, then signs off. Only after that do we insulate, board and tile.

We Pull It, Not You

Global Remodeling Pros files the permit and meets the inspector. You are not the one calling the county or waiting at the house for a window.

Why Unpermitted Work Costs More Later

Work with no record shows up when you sell the house or file a claim. A signed inspection is the cheapest paperwork you will ever buy.

Every permit and inspection report goes in the file we hand over at the end. The open wall photos go with it.

FAQ

Frequently Asked Questions About Bathroom Plumbing in Arnold, MD

White vanity top with a new sink and faucet after bathroom plumbing in an Arnold MD remodel

Yes, both can move, and the sink is far cheaper to move than the toilet. A sink drain is small and reroutes inside the wall. A toilet needs a wider drain, its own vent and a steady fall. A long move often means opening the ceiling below.

We replace any galvanized steel or gray polybutylene supply line we find in the open wall. Old shutoff valves and a cracked toilet flange go too. Sound copper or plastic line stays. Doing it while the wall is open costs a fraction of doing it later.

Moving or adding a drain, vent or supply line needs a plumbing permit from the county. Swapping a fixture in place usually does not. We pull the permit and meet the inspector for you. Call Global Remodeling Pros at (443) 331-9613 to book a free consultation for your Arnold home.
