AOS Bath is a water heater specialist that believe in empowering homeowners with knowledge and choice. You no longer have to buy obsolete technology. We are also the first company in Singapore to bring in this cutting edge water technology so that you are no longer limited to what contractors want to sell. In Singapore and certain parts of Asia, water heaters we have been using for the last three decades have seen almost no technological improvement. In the interest of providing cheaper products, many retailers bring in the lowest technology for home owners.
