Hi,
I am going to build a small (7m2) wet room on the ground floor of a granite farmhouse. The rest of the ground floor is drained breathable limecrete.
In the wetroom at present there is compressed (structural) drainable Foam Glass insulation (Misapor). The insulating slab (lime/Misapor/sand) will go straight onto the geotextile which has the hot/cold water pipes on top (see photo).
There will then be water underfloor heating pipes. Then a 75mm levelling screed, followed by new cut granite flags of approx 400x600 (see photo).
The local quarry can also cut us a solid shower tray (900x1500) in granite to match the flags .
First question:
Is there any way a wetroom can be part of the breathable floor or am i best to separate it and use cement screed/tanking etc?
Second question:
Any tips for the shower tray. Does the granite need to be of a particular quality or grain, does it need to be treated or sealed? What is the ideal thickenss and slope? Will the other granite flags need to be treated?
Third question:
I want the heating pipes to run underneath the shower tray, but as it will be thicker than the flagstones will 50mm screed (with fibres) be sufficient to protect the heating pipes and support the stone shower tray?
Fourth question:
Should I put a layer of insulation board between the slab and the screed underneath the underfloor heating pipes? If so, what would you recommend?
Thanks for any help and advice.
