I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
We don’t have an electrical outlet that is convenient to plug a bidet into (for warm water) so that has prevented us from giving it a shot.
You don’t have to plug it in, it works with the water pressure
The heated ones need power. They preheat the water.
There are some you can connect a hot water line to them, but with a tankless hot water heater, it could be a few minutes before hot water is flowing through the bidet. On a winter day, so that would be rather uncomfortable, I would think.
We have a Tushy (Spa 3.0) that takes 2 water connections: a cold water and a hot water (comes from the tap line). That might work if you have hot water connection.
Now that you mention it, I recall that some products could tap into the hot water, but for at least one of the bathrooms that would be even a bigger PITA because the hot water lines are on opposite walls. Also with a tankless house, it can take a while for the hot water to flow, so the last thing I want is cold water flowing for the first 2 mins in the middle of winter. That doesn’t sound like fun.
