In my new home the toilet tank is in the wall. There is no access to the toilet shut off valve to install a bidet spray. The faucet has a reasonable distance from the toilet. I was wondering if is it ok to install the bidet spray on the shut off valve of the faucet? Is there anything that I have to mind?

Thank you for your help!

  • It's going to be interesting to use in the winter with the cold water being fed to the toilet...

  • I'd hope there is an access panel somewhere nearby. Plumbing fixtures don't last forever, valves, etc. need to be replaced. Maybe something on the wall behind the fixture?

It is basically the same water, and probably the toilet tees off of it.

Just need a longer pipe/hose, than from the toilet.
