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.

Signs you need us

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.

What you get

What remodel and new construction plumbing includes

A written scope by phase, a schedule that names the days we will be on site, and inspections we book and meet ourselves.
  • A walkthrough before you finalise the design, showing which layout choices are inexpensive and which ones move concrete
  • Existing drain, vent and supply locations mapped so the plan is built around what is actually there
  • Verification that the existing system can carry an addition — service line size, water heater capacity, drain and vent capacity, and gas load
  • Post-tension cable scanning before any slab penetration, which is nearly every home in San Tan Valley
  • Underground rough installed and inspected before the pour on new builds
  • Top-out rough with supply lines pressure tested and held before drywall closes
  • Shower valves set on blocking at correct height, with accessibility blocking for future grab bars where requested
  • Coordination with the tile setter on drain height and slope, the cabinet installer on sink base cutouts, and the electrician on disposal, dispenser and bidet circuits
  • Plumbing and gas permits pulled and every inspection scheduled and met by us
  • Fixtures set and trimmed, tested under real use, and a walkthrough at every fixture before final payment

New Construction & Remodel Plumbing details

Bathroom Remodels

The plumbing scope of a bathroom remodel is driven almost entirely by whether fixtures stay put.

ScopePlumbing work involved
Fixtures stay in placeNew valves and trim, new supplies and stops, reset toilet, new drain assemblies — the least expensive scope
Tub to walk-in showerNew shower drain and correct slope, valve relocation and height change, blocking, and often a larger drain line
Vanity single to doubleNew drain and vent configuration plus a second set of supplies — needs a wall open
Moving the toiletRelocating the closet flange and drain, which in a slab home means cutting concrete and scanning for post-tension cables first
Full gut and relayoutComplete 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
  • Gas line for a range conversion — see gas line services
  • 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.

Pinal County's continued growth means a lot of this work across the region. Our broader take is in new construction plumbing in Pinal County's growth boom.

Working With Your Other Trades

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. 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. 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. 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. 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. 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.

Questions we get

New Construction & Remodel Plumbing FAQs

  • 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.
