water pipes over a doorway

[chopsaw]

I need to get water from the kitchen to the downstairs bathroom via

shorter route. At present the water has to go upwards from the kitche into the loft, across the loft and then back down to the bathroom. I would be far more sensible to take the water "horizontally" to th bathroom. This could be achieved by taking the pipes up one side of door frame, across the top of the frame and down the other side of th frame from where it can go into the bathroom. I did think of buryin the pipework in a concrete floor across the bottom of the doorframe but burying copper pipes seems to be an arcane art full of pitfalls an gloom and doom warnings. I would like to know if there are any reason why I cannot take the pipes around the door frame. Or can anyone giv me a definitive method for burying a short length (1.5 metres max) o water pipe across the floor in front of the door and therefore subjec to a lot of footfall?

Thank

If you want to bury pipework I'd do it with plastic. You can get a corrugated plastic sleeve to enclose your Hep2O / Speedfit / whatever in (so you can replace it if something bad happens to it, as per British Standards & Building Regs)

Seen it done lots of times, even with gas pipes, so presumably it's an accepted thing to do. Doesn't look very aesthetic though.

Can't you take it straight up the wall (boxed in if need be?) and into the void above the ground-floor ceiling, then bring it down into the bathroom by a similar route? A bit more 'conventional'!
