I'm going to be re-fitting my bathroom soon as the previous owners took out the bath and replaced it with a shower cubicle. However this will mean moving the heated towel rail to the opposite wall. I'm sure I can run the pipes under the floor to get to the other wall no problem, but then I would need to sink them into the wall to come out where the towel rail will be. I can't run up the wall as this will look awful and the bath is also on that side. And I also can't create studwork for the pipes as the bathroom is tiny and I can't afford to loose the space (yes it's that small!) Can I channel out the breeze block party wall to drop the pipes into or is this prevented by any regs?

You'd be best to keep them your side!

Although space is tight, I 'think' you can use microbore to some towel rads, so it may only be 7 mill. recess and cap it into stock 12mil plasterboard.......?

But even with 15mil copper, can you not spare even an inch? use 9.5m plasterboard over 15mil pipe? If so just take the existing plaster off and rebatten with some 16mil timber, then use 9.5pb over the top.

Not ideal, but at leas then if you neighbour drills through and hits a pipe your side, it will be their fault!!

Alternatively, get a leccy one, then if they drill though it, they'll fry!

If you are going to chase into a Party Structure then you should serve notice under the Party Wall act. This would be wildly disproportionate to what you want to do.

Besides, a 'breeze block' party wall doesn't sound too thick to me and sinking a 30mm deep chase into it may be too deep.

Why not fore go a heated towel rail and fit electric under floor heating? Wouldn't take up any floor space. A cheaper option would be to fit a fan heater at high level - although you'll need to check dimensions against the 'bathroom zones'.

The block or brick wall itself will be covered with either about half an inch of bonding followed by a couple of mmm of finish or a 1/2" board dabbed on followed by finish. Chase that out and you will get microbore in.

Personally I'd just crack on with the job.
