We are renovating a guest bathroom and want to install a wall mount faucet, rather than have the faucet mounted to the vanity. I'm concerned that all plumbing and the valves will be sealed inside the wall, so any future repairs/replacement will require cutting into the wall. Also I don't see how you can have the shutoffs that usually go underneath the sink since the plumbing isn't exposed.

Does anyone have any experience with these, and is there anything special to installing them?

thanks

Mike
