need help with Hansgrohe valve

michoumonsterFebruary 14, 2013

Hi all, I bought a hansgrohe thermostatic roman tub filler set. This is the rough-in valve # 04124181

My GC told me that it requires a special 2.5" diamond drill bit that he cannot find anywhere. I can't imagine that it would be this difficult to install since Hansgrohe is pretty popular. Did anyone else find this to be the case or perhaps there is a trick he doesn't know about?
Thanks for any advice!

I wonder if he could get one from the stone countertop fabricators?, or have them come out to drill a hole.

sloyd, thanks for the tip. He did ask our stone fabricator but the fabricator said the largest bit he has is 2.25".
I guess it is because I have a quartz tub surround as opposed to the usual tile..
I will have to call up Hansgrohe customer service to ask.

In the yellow pages - look up concrete hole drilling. I've had 6 / 8 / 10" holes drilled in concrete.

" I've had 6 / 8 / 10" holes drilled in concrete."

I had to punt an exhaust vent for a large paint spray room through a 5 foot thick tool rim rated concrete floor.

The vent was 32 inches in diameter.

It only took about 24 hours of drilling with a huge core bit.

It took longer to erect the scaffold to hold the core up 35 feet to the floor below.
And another 8 hours or so to lower the core down to the 'basement' floor.
It took a lot of rounds on the chain hoist.

It's not the fall, it's that sudden stop :)
