Genie Bath Systems provides homeowners with custom bath remodeling solutions, to include a full-line accessibility needs. All of our products are custom made in the USA. Factory Certified Installation.Lifetime Warranty.100% Financing . PLEASE NOTE: WE DON"T PERFORM KITCHEN REMODELS

"Last October, my sister, an elderly veteran living alone, contracted Genie Bath Systems to remodel her master and guest baths. She was diagnosed cancer and passed before the remodel was complete. Which, to be fair as we were not able to work with Genie while attending to my sister. The contract was expensive. Very expensive. The cost of the remodel is close to 1/4th the value of her home. I noticed there were issues with the remodel that showed a surprising lack of attention to detail. Genie sent people to address the issues twice. Yet issues remain. My calls to my contact at Genie are now being ignored. Also, the only document I have for the remodel is the contract my sister signed. It is not detailed. I have and continue to ask for a breakdown of the cost. An estimate or work order. This request is also being ignored. I am disappointed and have to wonder why Genie will not provide this information. I have several other questions for Genie that I will not go into here. But based on my experience, I cannot recommend Genie. In fact I would warn anyone considering Genie to be very careful about the cost of the contract."

See that man in the middle? Yes, that’s me…Ryan Stegent. And, yes, those are ALL my kids! Those children are the ones that motivate me to work hard and do the very best job I can every single time. Oh and by the way, I’m a 3rd generation plumber with over 30 years of experience. I’m a product of over 60 years of plumbing and that is something you can put your trust in! Please call or click for a free estimate today!

"I can’t say enough about Ryan Stegent Plumbing!!! As with any home service, one expects courtesy and care for one’s property. From the first contact to project completion, Ryan was a consummate professional. Ryan and I were in continuous communication related to the job. He was very responsive to questions and flexible to my schedule. When he got to my house, he had everything he needed to do the job and did exactly what I asked him to do. No negotiating an easier path. I really appreciated that. When all was said and done, Ryan had done a superb, professional job despite the heat in the attic (over 120 deg F). If one can do a professional job under difficult conditions, I’d trust him to do any work on my house. I would hire this guy in a second for any future plumbing job. Oh, it was also a nice touch that he charged what he said he would."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
