"Contacted Mike after waiting for the original plumber we called to cal back (never heard from him) . My daughter told us about My Guy had plumbed their bathroom. Mike told us he would be in Spokane on the 10th of March and that he could do a laundry room sink install in the afternoon. We sent him pictures of the old sink and the plumbing set up. He arrived as promised with all material in hand and within 4 hours he and his apprentice completed the job. The completed project was far better than we had ever hoped for. They did a total cleanup and removed the old concrete sink and did it all at a reasonable price. We would not hesitate to recommend Mike for any plumbing job."

"From start to finish Plumbline Pro is amazing. He walked me through all the parts needed. But never felt once I was being upsold or lied to. He's right to the point no nonsense. I hope I don't ever need to call him but I know that he is reliable and will be there if I need help at any time."

"Called in the morning and reached professional dispatcher who advised a service tech would respond in about two hours. Received a call about 20 minutes later from the tech who said he was on the way. Arrived with everything needed to fix my shower--the shower arm broke off inside of the wall. I was anticipating a messy, expensive repair that could have included removing tiles and/or drywall to access the problem. Mr. Steve Haller expertly removed the damaged part and then rethreaded the fixture inside of the wall without issue. He performed a leak/pressure test and then installed a new shower arm and shower head before cleaning everything up. Fantastic work, very timely, and professional. Will definitely call them again for any plumbing issues."

"Manny was extremely professional and thorough. He installed a rain shower and faucet for me. He had to cut the drywall and plumb a separate line to get it installed. I could not be happier with the quality of work he performed. I recommend him to all of my family, friends, and clients! If you are looking for an amazing plumber and an exceptional experience use Manny at Royal Plumbing!!"

"The entire process from the initial phone call to completion of the project was very professional and very easy.  Richard understood the exact services  and skills I needed and he was able to schedule time to complete the installation within one day of my call which was superb.
The price he charged for the project was very, very reasonable.
We also had interesting and wide ranging non-plumbing related conversation. 
I would highly, highly recommend him and if I need plumbing services again (which I hope, for my sake, I don't)  he is the very first call I will make.

"George called me and let me know he would be on his way. He was on time. I had a leak that a previous person didn't seem to know what to do with. George diagnosed the problem, got the correct parts, installed them and fixed the problem. I would call them for any plumbing needs in the future."

"Wonderful. Tom and Justin were enroute not only the same day, but in an hour or so. Hubby had installed new water softener and the kitchen sink had air constantly in the line. His troubleshooting did not resolve our issue. Professional, knowledgeable, courteous, and humorous. Tom found the dual minor issues right away. This is the 2nd time I've used A River City and they have become my go-to plumbers."

FAQs for plumbing installation for a remodel or addition projects in Spokane, WA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
