Hello, it's time for a renovation of the basement. Started over the weekend to begin dehumidifying under the tiles and ceramic tiles.
The goal is to replace the radiators with water-based underfloor heating. About 65 m2 excluding the boiler room and garage. Surface renovate all rooms. Sauna, shower, laundry room, toilet, and a bedroom.
In the picture, first is the shower room and towards the outer wall is the sauna.
Planning to lay epoxy floors in the sauna, shower, and laundry room.
Need some tips and ideas with the underfloor heating. Should one lay on concrete or use self-leveling compound or gypsum over the underfloor heating coil? Concrete requires a long drying time, self-leveling compound and gypsum are expensive. How thick a layer is needed? Is reinforcement necessary?
How about floor drains and the concrete around them, thinking mainly about the one in the shower that is used daily? Do these need to be replaced or is a strong dehumidifier for a few weeks enough?
There will probably be more questions eventually. Is there anything else important to consider?
