Remodel & New Construction Plumbing in San Tan Valley
Remodel plumbing lives or dies on two things: what is behind the wall, and whether the plumber shows up when the schedule says. We have no control over what the original builder did in 2004, but we can find out before demolition rather than after — and we are relentless about the schedule, because a plumber who misses a rough-in date sets back four other trades.
New Construction & Remodel Plumbing in San Tan Valley
What you need to know about new construction & remodel plumbing here
Most of the work we do here is master bath renovation in the 2000s tract homes, tub-to-shower conversions as households age in place, kitchen remodels that move a sink or add a pot filler, casitas and additions on the larger lots, and new-build work for custom homes and infill.
One local note worth planning around: San Tan Valley incorporated as a town on August 5, 2025, and permitting for projects here has been moving under the new town's authority. We track where a given project's permit needs to go, which is not something you should have to figure out on your own.

When to call about new construction & remodel plumbing
If any of these describe what you are seeing, it is worth a phone call — most of them get cheaper the earlier they are caught.
You are planning a bathroom or kitchen renovation
Get the plumber in during design, not after demo. Where drains and vents already are determines what your layout can be and what it will cost.
You want to move a sink, toilet or shower
Moving a fixture means moving drain and vent, which in a slab home means opening concrete. Entirely doable — and materially more expensive than keeping fixtures where they are.
You are converting a tub to a walk-in shower
Our single most requested remodel in the 55+ communities. Drain location and slope, valve height and blocking all change.
You are adding a casita, a guest suite or an addition
New supply, drain, vent and often gas, tied into an existing system that has to be verified for capacity first.
You are building new
Underground rough, top-out, gas rough and finish — coordinated with the GC's schedule and the inspection sequence.

New Construction & Remodel Plumbing details
Bathroom Remodels
The plumbing scope of a bathroom remodel is driven almost entirely by whether fixtures stay put.
Scope
Plumbing work involved
Fixtures stay in place
New valves and trim, new supplies and stops, reset toilet, new drain assemblies — the least expensive scope
Tub to walk-in shower
New shower drain and correct slope, valve relocation and height change, blocking, and often a larger drain line
Vanity single to double
New drain and vent configuration plus a second set of supplies — needs a wall open
Moving the toilet
Relocating the closet flange and drain, which in a slab home means cutting concrete and scanning for post-tension cables first
Full gut and relayout
Complete rough-in: drain, vent and supply redesigned for the new plan, inspected before close-up
In post-tension slab homes — which is nearly all of San Tan Valley — any concrete cutting starts with a scan for the tendons. This is not optional and it is not something to leave to a general contractor's saw operator. See slab leak detection and repair for why that matters so much here.
Kitchen Remodels
Sink relocation, including island sinks that need a vent solution — usually an air admittance valve or a loop vent depending on what the inspector accepts
Pot filler installation, which needs a supply line run through the wall behind the range and correctly secured
Dishwasher supply, drain and air gap or high loop as required
Refrigerator water line, ideally fed from an RO system if you have one
Instant hot water dispensers, filtered water faucets and under-sink RO
Garbage disposal sizing — worth upgrading during a remodel rather than living with the builder unit
Aging in Place — A Real Local Market
Solera at Johnson Ranch, the Trilogy section at Encanterra, and a growing share of longtime homeowners across town are doing accessibility renovations. The plumbing side of that work is specific and it deserves to be done thoughtfully:
Curbless or low-threshold shower entries, which require the drain and slope to be planned from the rough-in — not adapted later
Comfort-height toilets and, increasingly, bidet seats requiring a nearby GFCI and a supply tee
Thermostatic and pressure-balancing valves set for scald protection, which matters more as skin sensitivity changes
Handheld shower systems on slide bars with the correct valve configuration behind them
Lever handles and easy-reach shutoffs throughout
New Construction and Additions
For new builds, casitas and additions we work the standard sequence: underground rough before the slab pour, top-out rough after framing, gas rough, then finish and set. Each stage has an inspection and the schedule has to accommodate them.
Where an addition ties into an existing home, the first job is verifying that the existing system can carry it — service line size, water heater capacity, drain and vent capacity, and gas load. We check all four before quoting, because discovering the water heater cannot serve a new guest suite after drywall goes up is an expensive conversation.
On a remodel we coordinate with the tile setter on drain height and slope, with the cabinet installer on sink base cutouts and supply locations, with the electrician on disposal, dispenser and bidet circuits, and with drywall on when walls can close. We schedule around them and we show up on the day.
If you are running the project yourself, we will tell you what has to happen before we come back and what we need from other trades — because a homeowner-managed remodel usually fails on sequencing rather than on the work itself.

How we work
Our new construction & remodel plumbing process
No surprises, no mystery. Here is exactly what happens from the phone call to the walkthrough.
1
Walk it before you finalize the design
We look at existing drain, vent and supply locations and tell you which layout choices are inexpensive and which ones move concrete. This conversation saves more money than any other part of the project.
2
Written scope, fixed price, real schedule
Itemized scope by phase with a fixed price, plus a schedule that names the days we will be on site for rough and for finish.
3
Permit and inspection management
We pull the plumbing and gas permits and schedule the inspections, tracking the correct jurisdiction as San Tan Valley's town authority takes shape.
4
Rough-in, tested and inspected
Drain, waste and vent installed to code, water lines run and pressure tested, everything inspected before walls close. Post-tension scanning before any slab work.
5
Finish, set and walk through
Fixtures set, valves trimmed, everything tested under real use, and a walkthrough with you at each fixture before final payment. Warranty in writing.
What it costs
What drives the price of new construction & remodel plumbing
We do not publish flat prices for work nobody has looked at — that is a guess dressed up as a quote. Here is what actually moves the number, so you can read any estimate you receive.
Whether fixtures move
The single biggest driver. Keeping drains where they are keeps the project in the modest range; moving a toilet or shower drain in a slab home means concrete work.
Slab work and post-tension scanning
Any concrete cutting on a post-tension foundation includes scanning, cutting, plumbing, patching and cure time. It is real work and it is not where to economize.
Fixture count and complexity
A single-vanity guest bath is a fraction of a master suite with a double vanity, freestanding tub filler, multi-head shower and a water closet.
Fixtures you select
We install what you buy or supply what you want. High-end tub fillers and multi-outlet shower systems need more rough-in work behind the wall, not just a nicer trim kit.
Existing system capacity
If an addition or a big new shower exceeds your water heater or your supply line, upgrading those is part of an honest quote rather than a surprise at finish.
Permits and inspections
Passed through at the jurisdiction's cost and coordinated by us. Skipping them is not something we will do.

We hold our dates
A plumber who misses a rough-in sets back four other trades. Our scope names the days we will be there for rough and for finish, and we are not the reason your schedule slips.
The conversation that saves the most money is free
Whether fixtures move is the single biggest cost driver. We walk it with you before the design is final, because keeping drains where they are gets most of the transformation for a fraction of the plumbing.
Post-tension slabs handled properly
We scan before cutting, every time. This is not something to leave to a general contractor's saw operator on a foundation full of tensioned steel.
Aging-in-place done as a project
Curbless entries, comfort-height fixtures, thermostatic anti-scald valves and grab-bar blocking planned from the rough-in rather than adapted afterwards. Steady work in Solera and Trilogy at Encanterra.

Flat-rate pricing agreed before work starts, and we will tell you honestly if there is a cheaper answer.
One of the newest communities in town — owners need builder-warranty plumbing fixes, first softener installs and tankless upgrades as warranties expire.
Fulton Homes community at Ocotillo & Meridian (Queen Creek-annexed but searched as San Tan Valley) where new-construction plumbing and move-in softener installs dominate calls.
Luxury Shea Homes golf community in the 85140 ZIP (annexed by Queen Creek before incorporation), with high-end fixtures, a Trilogy 55+ section and premium softener and RO demand.
Affluent agritainment hub around Schnepf Farms and the Queen Creek Olive Mill, with nonstop luxury new construction driving softener and tankless demand.
Yes, but in a slab home it means opening concrete to relocate the drain and vent, and in San Tan Valley that means scanning first for post-tension cables. It is entirely doable and it is a real cost line. If the budget is tight, keeping fixtures in place and upgrading everything else gets you most of the transformation for a fraction of the plumbing scope.
Rough-in is typically one to two days once demolition is complete, then we return for finish and fixture setting after tile and cabinets, usually another day. The gap between those is set by the other trades, not by us — and we hold our dates so we are not the reason the schedule slips.
If you are moving drains, adding fixtures or altering gas lines, yes. Like-for-like fixture replacement in the same location generally does not require one. Since incorporation in August 2025, permitting for the area has been transitioning to the Town of San Tan Valley, and we confirm the correct jurisdiction for each project.
Yes — it is one of our most requested remodels, especially in Solera, Encanterra and among longtime homeowners planning to age in place. It involves relocating and re-slopeing the drain, changing valve height, adding blocking for grab bars, and often upsizing the drain line for a higher-flow shower.
Yes, on both remodels and new construction. We work the standard sequence of underground, top-out, gas rough and finish, coordinate with the other trades on drain heights and cabinet cutouts, manage our own inspections, and hold our scheduled dates.
