Self build- sub floor- plumbing

Liv1989

Hi all,

Any advice would be appreciated.

Currently completing a self build.

Sub floor is in and kitchen company informed us a duct cannot be input at this stage for island hob so we will go with an alternative.

However, this then started us thinking. I am now panicking, there has been no rough plumbing for sinks in kitchen or utility. Is this going to be a huge issue or am I making a mountain out of nothing?

Any help would be much appreciated as I am now tearing my hair out thinking we've made a mistake with other services that cannot be rectified.

We are in the process of locking in a plumber but just wanted to see if anybody might have any advice.

Just sub floor is in? whats going on top of the sub floor ? insulation / screed? whats the duct the kitchen company require? is it for cables to supply hob or is it for extract air?

The subfloor will have 150mm insulation board, with screed and UFH pipes. It's for the extraction as it's a downdraft hob.

possibley could reduce the insulation over / under dubt to 100mm & use the flat ducting? Or if not get a re-circulating version of the down draught hob.
