"Schmitty's Plumbing responded to my Angi's service request almost as soon as I submitted it, and they beat out three other Angi plumbing companies in terms of pricing and transparency. I hired Schmitty's to remove an old double bowl kitchen sink and faucet with a new single bowl sink and upgraded faucet. There was no upselling or attempts to convince us to replace our garbage disposal which two of the other plumbers recommended we do. We saw no reason to replace our disposal which functions well and is not that old. Partners Drake and Gage came out to our home as scheduled, and they got to work immediately working efficiently and thoroughly. We appreciated their no-nonsense, honest, prompt service, and very fair pricing. I chose Schmitty's based on the positive customer reviews, and would hire them again. I told them I would recommend them to all my friends who have plumbing needs!"

"Very well done! Tennant called to notify us of a leaking garbage disposal unit. Received a phone call when technician (Raman) arrived with a clear diagnosis before work was to be completed. Used an Angie's list special that was honored with no up-charges or additional work added. Drain Pro is now my go-to for all plumbing needs."

"I needed some additional work done to remove a kitchen disposal and put new pipes in and also to have pipes replaced on a back bathroom we had just remodeled. Mad Pipers did such a great job with the large re-piping job I hired them for over the summer, I didn't hesitate to call Zack & Ragen for the quote for the additional work. They replied promptly and we scheduled the work within a few days. The work was completed by Curtis who arrived on-time and did a great job! I wouldn't hesitate to recommend them to anyone in need of plumbing services!"

"Mark was able to replace my water heater quickly and efficiently and went the extra mile to make sure I understood the function of the heater and the water leak gauge -- my old one was improperly installed and submerged by water (super helpful. not.) On a follow-up call he even turned me on to a trusted electrician, cuz I need a bathroom ceiling fan installed. Two thumbs up!!"

FAQs for plumbing installation for a remodel or addition projects in Issaquah, 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.
