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."

"Expo Home did a fantastic job from beginning to end. Maurice our sales representative came to our home and very thoughtfully walked us through everything. He helped us to make a difficult and expensive purchase decision. The contract was signed Friday evening and the work was completed by Thursday afternoon. The installers Ricardo and Omar arrived promptly on install day morning at 8am and worked quickly to do all the work by 4pm. They respected our home and kept work areas clean with tarps. Omar especially kept me informed of the progress of the project throughout the day. Ricardo as the lead installer was very skilled in performing the work and knowledgeable about all the details of the project. I would highly recommend Expo Home for your next tub to walk in shower conversion. Thanks to everyone at Expo Home team and satisfied to be member of their family."

Looking for a professional, trustworthy, and reputable plumbing company in Waco/Temple? Look no further than Smelscer Plumbing Inc. We are dedicated to providing top-notch plumbing services to homeowners like you. Contact us today!
"We had SMELSCER PLUMBING install two 50 gallon water heaters in 2018, one upstairs & one downstairs @ $750 each, with a 6 YEAR WARRANTY. Within 1 YEAR the water coming from the upstairs one smelled awful - like rotten eggs. They drained it and charged us another $200. NOW the UPSTAIRS water heater HAD COST US $950. Within 3 YEARS (of a 6 YEAR WARRANTY), the upstairs water heater QUIT WORKING. They said it had to be REPLACED (UNDER WARRANTY) & said the LABOR TO INSTALL IT would be $600, meaning the upstairs water heater NOW COST $1550. Also, even though they were installing a NEW WATER HEATER, they would only honor the 3 YEAR WARRANTY left on the FAULTY WATER HEATER. WHAT SHOULD THEY HAVE DONE? They should have gone back to the company and NEGOCIATED (on behalf of their client - US) a NEW WATER HEATER with a 6 YEAR WARRANTY, and NEGOCIATED with the company to PAY THE $600 INSTALLATION FEE. They DO NOT BACK UP THEIR CLIENTS!!! AVOID THIS COMPANY!!!"

FAQs for tankless water heater installation projects in Killeen, TX
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.
