Progressive hole in porcelain tiles

[One Day]

I'd aim for a bigger hole and fill with colour matched silicone.

Sounds like a plan! It'd have to be white as the tiles are an off white - should be fine at that given the relative size of the gap.

What size bore do you normally go for a 15mm pipe?

 

[Flintstone]

Seing as a copper pipe isn't going to expand, a 15mm hole would be perfect if you can get it accurate enough, in my humble opinion of course! When I'm measuring I measure to one side of the pipe then to the top or bottom then use those two marks to line up your hole guide.

That's why I went 18mm, not being a pro

The only additional thing here is the fact that it's the first tile off the floor that needs the holes, so presume i'd measure to the floor taking off the 3mm spacer.

As it's turned out, this is a bit of a PITA - the first 2 tiles are the 2 requiring the rad holes, meaning a drain down of the system - then a further drain down to fit the s***ing thing. The joys

Errrrr
Sorry to state the obvious.
Chase the pipe in deeper

View attachment 87726 what you need is a hole like this with no cover plate required

Yeah I bet there's a 5mm gap the other side too! Hahaha

 

[Old Mod]

They might be a bit bling them big cover plates!

Andy, I'm sure if they cut you in half you'd have,
'Made in Yorkshire' running straight through the middle! Hahaha

thanks for the tip! But.... my walls are 3 pieces of plasterboard D&Dabbed, 19mm thick each. I've already gone into 2 boards, cutting into the next is likely to go through potentially - and given my insulation boards/electric mat and screed are now laid, I'm not sure i can get the pipe to push back that far

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.
