"They came within a day and converted by old 3 knob setup to a more modern 1 knob setup which required cutting and reconfiguring pipes. The whole job was done in a half day and the shower/bath was repaired. Very nice plumber and front office team as well."

"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

"Bob Larson is a scam. I bought a $10,000 on-demand water heater in November 2023. Bob Larson Plumbing recommended and installed the unit; at first, it was great. Since December 2024, the system has been having issues randomly turning itself off. It was more of a nuisance than a real issue at first. I could turn it back on. Bob Larson was called and came out twice but could not resolve the issue. In March of 2025, the problem got worse, and hot water was random at best, even if I reset the heater manually. Instead of resolving the issue or exchanging it, Bob Larson Plumbing is trying to sell me another unit. I am still under warranty. My original receipt shows a 5-year warranty on parts and labor. Bob Larson is an upselling scam. They will not be getting any more of my money."

"Kris and Gabe at Havenkraft are the best! After researching local contractors and reading reviews we reached out to Kris to get a bid. They worked on our two bathroom renovations. We had them completely redo our primary vanity and shower/toilet bathroom as well as our full bathroom with tub. From the bid process to the final touches on completion it was such a pleasure working with them. They are straightforward and hardworking craftsmen. They truly care about the quality of the outcome as if it were their own home. I would recommend them to anyone looking to get a high quality remodel on a bathroom or kitchen. From the bid process, to selecting colors and materials everything was itemized and costed out so that we never had any surprises. Kris helped us narrow down to our final choices and our bathrooms are absolutely beautiful and functional. Every day we get to enjoy a spa like bathroom in our own house!"

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