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."

"Called before arriving, got there on time to assess the issue. Introduced himself in a professional manner, told him what was going on & he got strait to work. After a few minutes, he was able to figure out the issue. Explained to me what happened, how it happened, & how he was going to fix it. Let him continue his work, and before I knew it, the fridge was working again. He called me in there and explained what he did, walked me through and showed me that everything was working again on my icemaker and fan. Definitely recommending him to friends and family. Very difficult to find an honest person who genuinely cares about the customer & very reasonable pricing for services."

Tankless water heater installations FAQs

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
