When was your home or office building built? If it was more than a decade or so ago, you might want to look at the restroom facilities available and consider upgrading to a modern toilet. The prospect might sound silly, but modern toilets are actually surprisingly cost effective, and are effective in cutting costs where you would not think there were any to be cut. Most importantly, it is not worthy that they are more water efficient toilets than older models, and more water efficient means that modern toilets are going to save on your water bill, or the cost of utilities if you own an office building and rent the space. Less money towards utilities means more in your pocket, and that’s always a good thing!
Perhaps if you own an office building though, you might consider a commercial toilet if you anticipate it seeing a lot of use. Light commercial toilets and modern toilets for the home usually look similar, but a commercial toilet is made to handle more flushes and general use, so if a restroom is open to the public, it is a better idea to get this type for your facilities rather than a cheaper private use toilet.
No matter what your needs are though, a modern toilet is a great way to save money every month on bills, and is a more reliable option to their older counter parts.
