Hi everyone, we are now slowly making our way out of the ground, Isoquick insulated raft is now down, what a speedy process that was - 1 day for 190m2 with the steelwork completed the following day. Just thinking ahead to UFH next week and the concrete pour. The UFH will be within the 250mm concrete slab. The slab will not be visible but will take the floor finish.

For the shower, I'm thinking of having it arranged as a wet room, which leads me to the first question. Has anyone had UFH under the wetroom shower part to help dry things out?

Secondly, I need to recess the shower area in this part - what have people used for formwork? I will need to recess the whole area of the 'shower tray' and then further from the waste below. I have an idea of how to construct but cannot think of how to keep this off the Isoquick and at the right height, etc. Any pointers?

Thank you

Jonny

Slightly different floor build than yours, but we used offcuts of insulation cut to the size I needed and a few very long nails to hold it all in place and the some concrete blocks on top to stop it floating off during the concrete pour. When I was ready broke out the insulation, did the drainage conections and back filled with concrete as needed.
