Adding a bathroom is the one project in this trade where the layout does not start with the room. It starts with the waste line. Drainage runs on gravity and needs fall, so a new toilet has to reach the main stack at an angle that works, and the vent has to reach open air. That single constraint decides whether the space under the stairs can become a half bath or whether the only workable spot is the wall backing the existing bathroom. Everything else, the door swing, the fixtures, the finishes, gets designed after that answer. This is also the most permit-heavy work we do. Adding a fixture means the plumbing plan gets reviewed, the rough-in gets inspected before it is covered, and electrical for lighting and a fan goes in the same review. In the city that runs through the City of Yakima Building Division. In Terrace Heights and Moxee it runs through Yakima County instead. Selah and Union Gap each have their own counter. We work out which one applies at the walkthrough, because the review timeline is part of the schedule rather than something to discover halfway through framing.
We start by locating the existing stack and mapping realistic drain routes from each candidate location, then price the options against each other rather than presenting one. A half bath in a spot that reaches the stack easily and a full bath that needs a new vent through the roof are different budgets, and it is better to see both. The written scope covers framing, drainage route, venting, electrical, and where the inspections fall in the calendar. Ventilation is not an afterthought here, since a new bathroom without a properly ducted fan turns into a moisture problem in the room next door.

Turns a closet, landing or pantry into a toilet and sink where drainage allows.
Adds a shower, which raises the venting and drain sizing requirements considerably.
Determines the location before layout, since drainage cannot be routed anywhere convenient.
Proudly serving Yakima, Selah, Union Gap, West Valley, Terrace Heights and Moxee for 14+ years.
We scope bathroom work as ten separate jobs, from an accessible walk-in shower to a full bathroom addition. What separates them is not finish level but whether the fixtures move, because that decides the permit, the inspections and most of the cost. Start with the one that matches your project.

Service covers Yakima plus Selah, Union Gap, West Valley, Terrace Heights and Moxee. Those are not one jurisdiction. Selah and Union Gap each run their own permit counter, Terrace Heights and Moxee route through Yakima County, and West Valley sits inside the City of Yakima after annexation.
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.
There is no single price for a Yakima bathroom remodel. Cost follows whether the fixtures stay in their existing footprint, whether the supply and waste lines behind the wall get replaced, and what the permit scope turns out to be. A refresh that reuses the drain and a remodel that relocates it are not comparable jobs. We price after a walkthrough, not before one.
In most cases, yes. Yakima County adopted the 2018 International Codes, and bathroom work that alters plumbing or electrical routing needs a permit and inspections. Inside the city limits that runs through the City of Yakima Building Division, while Terrace Heights and Moxee route through Yakima County and Selah and Union Gap each run their own counter. We pull it either way.
Schedule follows the permit and inspection sequence, whether fixtures move, and lead times on tile and glass. A single-scope refresh inside the existing footprint moves faster than a remodel that relocates a drain or adds a fixture. Spring is the busiest stretch of the year here, so a March start booked in January runs a lot cleaner than one booked in March.
Usually the part you never see. Moving a drain, opening the wall to replace tired supply lines, and rebuilding a shower pan with a proper waterproofing membrane all cost more than the tile and fixtures most people are picturing when they start. If the layout stays put, the money goes into finishes instead. Working out which of those two projects you actually have is the first thing we do.
It depends on what the bathroom is doing wrong. Replacing a failing shower pan, or a tub nobody in the house can step over safely, solves a real problem and holds its value. A cosmetic swap on a sound bathroom is a preference rather than a repair, and we will tell you so. We would rather scope the smaller job correctly than sell you the larger one.
Moving fixtures is the single biggest cost lever in a bathroom. Relocating a toilet or a shower drain means opening the floor, re-routing the waste line, and adding a plumbing inspection that a same-footprint remodel never needs. Sometimes a few inches of gain is worth all of that and sometimes it is not. We measure and tell you which one you are looking at before anything gets ordered.
Yes. Adding a fixture changes the plumbing and electrical layout, so the work is permitted and inspected rather than treated as a finish project. Inside the city that runs through the City of Yakima Building Division, through Yakima County for houses in Terrace Heights or Moxee, and through their own counters in Selah and Union Gap. We identify which applies before the design is finalised.
Wherever the drain can reach the stack with proper fall and the vent can reach open air. In practice that means the strongest candidates are usually near an existing bathroom, above or below one, or backing onto the kitchen wall. Spaces far from the stack are not impossible, they are just a bigger job. We map the options before choosing.
Generally yes, and the reason is the shower. A toilet and sink need less drain capacity, less venting and no waterproofed wet wall assembly. Adding a shower raises the drainage requirements and brings a full waterproofing scope with it. If the goal is simply a second toilet for a busy household, the half bath is often the better value.
Longer than a remodel, because plan review sits at the front of it and the rough-in inspection sits in the middle. Framing and drainage go quickly once approved. The schedule is usually set by review turnaround and by tile and glass lead times rather than by the construction itself. We build both into the calendar we give you.
