Remodeling a bathroom in a house built in 1962 is a different job than remodeling one built in 2012, and the difference is almost entirely behind the walls. The tile, the vanity, the fixtures, all of that is the same work in either house. What changes is what you find when the old surfaces come off, and in an older Arvada home the odds of finding something are high enough that it belongs in the plan from the start instead of arriving as a surprise on day three. None of this is a reason not to do the project. It is a reason to open a wall early and look.
Open One Wall Before You Commit to a Number
The most useful hour on an older bathroom project happens before any money is committed. Cut an access hole, look at what is actually in there, and price the job against reality instead of assumption.
What we want to see is the supply material, whether it is galvanized steel or copper or something newer, the condition of the drain and vent, and how the whole assembly is framed. That one look answers most of the questions that would otherwise turn into change orders. A remodel priced without it is a guess wearing a suit, and the homeowner is the one who absorbs the difference when the guess is wrong.
Because Wes holds a general contractor license alongside the master plumber license, opening that wall and closing it back up is the same company either way. There is no separate trade to schedule for an exploratory hole and no argument later about who is responsible for what got found.
The Galvanized Question
If the house still has original galvanized supply lines, a bathroom remodel is the single best opportunity you will ever get to replace the ones serving that room. The walls are already open. The access you are paying for anyway is exactly the access that work requires. Doing it later means opening finished walls a second time and paying twice for the same demolition.
Galvanized fails from the inside, so the pipe can look fine and be down to a fraction of its opening from decades of scale and corrosion. There is a specific version of this that catches people: the remodel goes in beautifully, the new fixtures are lovely, and the pressure at the new shower is disappointing. Nothing is wrong with the shower valve. It is being fed by an original branch line with a quarter inch of open channel left in it. New fixtures do not fix old supply, and no amount of showerhead shopping will.
You do not necessarily need the whole house done. Replacing the branches serving the bathroom while it is open is often the sensible middle ground, and we will tell you when the rest of the house genuinely can wait. That work is the same thing covered on our pipe repair page for Arvada, and it sits naturally inside a bathroom remodel rather than as a separate project later.
Cast Iron Drains and the Tap Test
The drain side in a house this age is usually cast iron, and cast iron drains corrode from the inside out. Sewer gas and moisture eat the pipe wall starting at the crown, so a stack can look perfectly sound from the basement, painted and dry, while the top of the pipe is paper thin.
Tap along it with a screwdriver handle. Solid pipe rings. Deteriorated pipe sounds dead and dull. Look for rust flaking at the hub joints and staining on the wall behind it. Sixty to eighty years is the honest working range for cast iron drain pipe, which means a great many original Arvada stacks are inside that window right now.
If the section serving your bathroom is thin, replace it while the wall is open. A drain that fails after new tile is in is a genuinely miserable repair, because getting to it means taking apart work that was just finished and paid for.
Venting Shortcuts From Somebody Else’s Remodel
Plenty of bathrooms in these neighborhoods have already been remodeled once, often in the seventies or eighties, and often by somebody working fast. The plumbing that resulted usually works well enough that nobody questioned it for forty years.
Every drain needs a vent, which lets air into the system so water can flow and so the trap seal is not siphoned out. Pull the seal out of a trap and sewer gas comes into the room. The tells are audible and olfactory: a trap that gurgles when another fixture drains, or a persistent smell that cleaning never touches. Under a sink you may find a mechanical vent screwed on where a real vent should have been run, or a wet-vented arrangement that was never right.
Moving a fixture makes this critical. A vent has to be within a certain distance of the trap it serves, so relocating a toilet or a sink four feet across the room can put it out of range of the vent that was serving it. That is a real part of the job and it is invisible in every photo of a finished bathroom, which is why it is the thing most likely to be skipped by whoever bids lowest.
Moving the Toilet Is the Expensive Idea
Of all the layout changes people ask about, relocating the toilet is the one that reliably costs the most, and it is worth understanding why before you fall in love with a floor plan.
A toilet drains three inches and it drains by gravity, which means the new drain run needs proper slope from the new location back to the stack. Slope needs vertical room. In a house with a basement below, that means opening the ceiling underneath and working in the joist bays, and there are rules about how much you can cut and where. On a slab, it means breaking concrete, and that changes the project entirely.
Sinks and even showers move much more easily, since a smaller drain needs less fall and there is more flexibility in the routing. So if the budget is finite, moving the vanity and the shower while leaving the toilet where it sits usually buys most of the layout improvement for a fraction of the cost. We would rather show you that tradeoff on paper than let you discover it after demolition.
The Things That Are Genuinely Worth the Money
Not everything found in an old wall is bad news, and a few upgrades earn their keep every time. Shutoff valves for the bathroom, so a future repair does not mean killing water to the whole house. A pressure balancing or thermostatic shower valve, which is code for new work anyway and is the reason nobody gets scalded when a toilet flushes. Replacing the angle stops under the sink and toilet, since fifty-year-old multi-turn stops have packing washers fused solid and will not close when somebody actually needs them to.
Proper blocking behind grab bars, or at least behind where they might go someday, costs almost nothing while the wall is open and is impossible to add cheaply afterward. And if the room is on an exterior wall, insulate the supply runs and seal the air gaps while you are in there, because our freeze-thaw cycles find every cold pipe in a house eventually and a bathroom on a north wall is a candidate.
If you are planning a bathroom in an older Arvada house and want to know what is behind the wall before you commit to a budget, call (303) 883-9075 or send us the details. We will look first and give you a straight quote against what is actually there, including the parts nobody enjoys hearing about. More on what we handle around town is on our Arvada plumbing page, and finished work is in the gallery.
Should I replace old pipes during a bathroom remodel?
If the house still has galvanized supply serving that bathroom, yes. The walls are already open and the access you are paying for is exactly what the work requires. Doing it later means opening finished walls twice. Replacing just the branches for that room is often enough, and we will tell you honestly if the rest of the house can wait. Call (303) 883-9075.
Why is moving a toilet so much more expensive than moving a sink?
A toilet uses a three inch drain that runs by gravity and needs proper slope back to the stack, and slope needs vertical space. With a basement below that means opening the ceiling and working within the joist bays under real limits on cutting. On a slab it means breaking concrete. Sinks and showers use smaller drains and move far more easily. Call (303) 883-9075.
My bathroom drain gurgles and smells. Is that a clog?
Usually it is a venting problem rather than a clog. Every drain needs a vent so water flows and the trap seal holds. When venting is inadequate, draining one fixture pulls the seal out of another trap and sewer gas comes into the room. Older remodels around here often used a mechanical vent or skipped it. Call (303) 883-9075.
What surprises are most common in a 1960s Arvada bathroom?
Original galvanized supply that has scaled nearly shut, cast iron drain pipe thinned from the inside, and venting shortcuts from a previous remodel. Occasionally framing that was cut through for pipe and never repaired. None of them are project killers, and all of them are cheaper to handle while the wall is open. Call (303) 883-9075.
