Alternately, you could have foregone the radiator and fitted Schluter's Ditra Heat or Ditra Heat TB to the walls and had heated walls instead of a great lumply bloody rad
Gives out 200w per/m2 and is sufficient for a primary heat source.

Wonder who's just been on Schluters course!

Like you've said yourself John, gotta keep up, or get left behind!

Sounds expensive....

I could just go nuts on the heated mirror pad, double it over - reckon that'll work?

Quite simple if you have a grinder and an ats blade just shave the back down where required

Hi all

I am about to start laying some 600x300x10 tiles, the first 2 of which will have 15mm pipes going through them for the towel rad. The issue i have is that i am using speedfit connections which i have managed to get mostly into the wall, but have a slight protrusion where the chamfered part of the fitting sticks out, therefore i need to use my 18mm ATS bit from the front for the 15mm pipe (bit of margin for error!), then some how chamfer the back of the tile to accept the speedfit fitting - I have bought a further 32mm bit to attack the tile from behind to drill halfway, to hopefully file down - from what i am reading, filing isn't really an option for porcelain.

Can anyone offer any advice as to the way to go with this slight problem

Thanks in advance

As before ... Angle Grinder on the back.. Will work a treat.

Thanks Gaz, it certainly did the trick... Although not having a small diamond blade, I used metal discs which have been great at cutting absolutely anything. I went through 2 on two holes!

Also my 18mm APS bit lasted just over one hole so ended up having to buy an adequate mid range £15 20mm jobby from the local tile shop...

Wondering now if I'll need something special to drill the holes for my towel radiator... I have a few small tile bits which are fine with normal tile, but will they actually touch the porcelain?

I have a kit that I picked up from eBay a while back.. About £50.( various diameters)... And has been top notch for me .. Especially for Porcelain
I believe the 365 kits are good

Don't think they're available currently.

Na I've looked.... £75 upwards....

I'll get by with what I have for now... Just wondering about these standard bits for the smaller holes

That will be down to teqnique, every tile drill bit will be able to achieve at least 3-4 holes.
Even tho they are dry bits, they all benefit from a damp sponge being held against them.

In Topps tile they do a Rubi drill kit for £50, and it's actually worth it.
Sizes 6,8,10,12mm wax filled dry bits that have M14 threads to fit direct to angle grinders.
Not bad at all.

I might consider that kit if these get blunt quick... The last 20mm I did earlier in the SDS, went a lot quicker for stopping and dunking in water..Defo the way forward
