Rough sketch bathroom

[JohanKson]

Currently planning the bathroom on the first floor. Wooden floor (prefabricated cassettes) with a basement underneath. Have spoken with the insurance company and they wish for us to pour a slab inside the bathroom about 70 mm with the underfloor heating embedded. I've looked around a bit now and am looking for a "quick-setting cement" so that tiles can be set as quickly as possible. Any tips on systems to use?

Ardex A34 Mix or A35 Mix for example.

Is there any chain that is a reseller for these or where should one turn to acquire such?

You don't need to buy specifically Ardex stuff. Go to the nearest well-stocked construction store and buy the brand they have. It could be Finjas or Maxits stuff as well, they are equivalent.
