"The original project I hired them for was to replace leaky faucets in both the kitchen and bathroom. Frank, the owner, was responsive and professional. They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."

"The short version of this review is we were very happy with the work Select Kitchen and Bath did for us and would not hesitate to use them again. Our project, which was completed in January 2025, consisted of a complete remodel of two full bathrooms which were vintage 1983. Amanda was our designer, Mark was the lead installer, and John was the project manager. All three of them provided welcome suggestions, good guidance and advice throughout the process… starting with clear and transparent service agreements. Select was very accommodating with scheduling and access to the house / workspaces. Questions were answered promptly by Amanda, Mark and John, and any concerns were addressed to our satisfaction. Our new bathrooms are great!"

"Ruben and the team did such a great job on the first project (2-3yrs ago) that I asked them to come back and finish my condo's water heater closet, which showed wear and tear from past water damage. They did a fantastic job in repairing the closet and adjacent living room's dry walls that it looked seamless to the rest of the unit. The team was always conscious of keeping the work area clean as they closed the area off with tarp and placed drop cloths down. I greatly appreciate the amount of high-quality work done in a short time span, especially when asked within two weeks of the project starting. I've recommended the team to my family and friends if they ever need a job done right by a team who is professional, courteous, and knowledgeable."

"It is my pleasure to review DMV kitchen and bath. They did an outstanding job from conception through to the last details in finishing an extensive series of renovations - complete kitchen tear-down and renovation, master bathroom and closet teardown and renovation, two bathroom complete retiling/renovation, building two new rooms out of a very large basement, and replacing two forced air HVAC systems - they managed all aspects including proper construction permits. They did high-quality work at a very good price. They did an outstanding job with the work, with high attention to detail. Their communication was very strong from beginning to finish, their initial plan recommendations were excellent, they made several recommendations to not only make the job better, but also make it more cost effective along the way. They were reliable and consistent, and very genuine, "real" people. I have to imagine there will be very high demand for their services. I can’t recommend highly enough. Very timely, excellent communication, quick and high-quality professional work at a competitive price."

FAQs for plumbing installation for a remodel or addition projects in Washington DC, DC

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.
