Best praise vs top criticism for TOTO Washlet S7A
“I have a Toto S7A washlet. I did a lot of research and I believe the high-end Toto washlets are the best you can get. Not sure what the sink has to do with it. You would get the water supply from the same one feeding the toilet. You wouldn't want to use hot water straight from the hot water supply anyway. Get a bidet seat that heats up the water internally. You will need a GFCI outlet beside the toilet. Don't be cheap. Get the outlet installed by an electrician if you have to. Buy the best bidet seat that you can afford. You're going to sit on this thing every day for the rest of your life. I bought an S7A washlet seat and a Toto Aquia IV one piece toilet and the Toto auto-flush unit to go with it. I had an electrician install a proper, dedicated GFCI outlet as recommended by the manufacturer. All-in-all it was almost $3,000. I would do it again. You get what you pay for. Best Wishes.”
“Generally speaking, fresh water is flushed into the system daily or multiple times a day when used so it does not sit stagnant for long. If you are leaving town or away for several days, draining the tank is always recommended. To avoid any concern around this though, upgrading to an instant water heating seat is a good way to remove that worry and provides a slimmer, more comfortable bidet seat as well. Toto has the S7 or S7A which would pair well with the Aquia IV and are instant water heating seats!”
