Vanity installation in Coeur d'Alene is mostly a question of what is behind and beneath the one you are removing. A straight replacement that keeps the basin over the existing drain is the simplest work we do, and under the 2017 Idaho State Plumbing Code as adopted here, replacing a fixture in its existing location does not require a plumbing permit. That changes the moment you add a second sink or shift the cabinet far enough that the trap arm has to move. Then it is a new fixture or a rerouted line, a plumbing permit through Coeur d'Alene Building Services, and an inspection before the wall closes. The other variable is the wall itself. In the older Garden District and Sherman Park Addition housing stock, framing from the early 1900s is rarely plumb and floors are rarely flat, so a modern rigid vanity that is built to sit tight against a wall will telegraph every deviation. We scribe and shim rather than caulking a gap and hoping. Floating vanities are the case where sequence matters most, because the blocking has to be in the wall before anything is closed up. Deciding on one after the drywall is finished means opening it again.
Bring us the vanity you want or let us spec one. Either way we measure the rough-in height, the trap arm location and the floor deviation before ordering, because those three numbers decide whether the cabinet you picked will actually sit where you want it. On a second-sink conversion we will tell you at the walkthrough that a permit is part of the job, so it is in the scope and the schedule from the start rather than arriving as a change order.

Same location, same drain, and no plumbing permit required for the swap.
Adding a second basin adds a fixture, which triggers a plumbing permit.
Blocking goes in before drywall closes, so sequence matters here.
Proudly serving Coeur d'Alene, Post Falls, Hayden, Dalton Gardens, Rathdrum and Spirit Lake for 15+ years.
A tub-to-shower conversion and a full bathroom remodel are different scopes with different inspections and different lead times on glass and tile. Start with the page that matches what you are actually planning, and if you are between two of them, that is worth a conversation rather than a form.

Post Falls issues its own plumbing and electrical permits. Hayden and Rathdrum do not, so those trade permits go through the Idaho Division of Building Safety instead. Dalton Gardens runs on the Dalton Water Association. Knowing which applies before demo is the difference between a schedule and a guess.
Frequently Asked Questions
Bathroom Remodel can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
It depends on whether anything moves. Replacing a plumbing fixture in the same location does not require a plumbing permit. Adding a new fixture, rerouting supply or waste lines, or replacing a water heater does. Coeur d'Alene Building Services handles building, plumbing, electrical and mechanical permits, and we pull them as part of the job rather than leaving it to you.
There is no single number, and any figure quoted before a walkthrough is guesswork. Cost follows whether fixtures move, whether the supply and waste lines behind the wall get replaced, what the tile and glass selections are, and what the permit scope turns out to be. We price after we have opened up the room and seen what is actually there.
Schedule follows the permit and inspection sequence, whether fixtures move, and lead times on tile and shower glass. A single-scope refresh in an existing footprint and a remodel that relocates the drain are not comparable jobs. The other variable is whether you have a second bathroom, because working around a household's only bathroom changes how we stage the work.
You cannot eliminate them, but you can find them early. Older Coeur d'Alene housing stock frequently has original cast-iron waste and galvanized supply that looks fine until it is disturbed. We open an access point and inspect the lines before finalizing scope, so the discovery happens during pricing rather than during demo.
Post Falls, Hayden, Dalton Gardens, Rathdrum and Spirit Lake, along with Coeur d'Alene itself. They are not interchangeable from a permitting standpoint. Post Falls issues plumbing and electrical permits directly, while Hayden and Rathdrum route those to the Idaho Division of Building Safety, and that difference lands on your timeline.
Tile, vanity setting, toilet installation and bathroom flooring are done in-house. That matters most on waterproofing, because the transition between the pan, the curb and the wall is where most shower failures start. When one crew owns the whole assembly there is nobody to point at when a detail gets missed.
Not if the new vanity keeps the basin in the same location and connects to the existing drain and supply. Replacing a fixture in place is exempt. If you are adding a second sink or moving the cabinet far enough that lines have to be rerouted, that is a plumbing permit through Coeur d'Alene Building Services.
Cost follows the vanity itself, whether plumbing moves, and what condition the supply lines and shutoffs are in once the old cabinet is out. Older homes here frequently have valves that will not close cleanly, and those get replaced as part of the work. We give you a written number after seeing the space.
Usually, but two things decide it: whether the wall is wide enough for two basins with workable spacing, and whether the drain can accept a second fixture without repiping. Adding a fixture requires a plumbing permit. We check the waste line configuration before telling you it will work.
A straight replacement in an existing footprint is typically a single day once the cabinet is on site. Anything involving new plumbing runs longer because the rough-in has to be inspected before it gets covered, and that inspection sits on the city's schedule rather than ours.
