Hello!

I'm planning to do a "surface renovation" of the floor in the laundry area of our kitchen. Tiles are intended.

Today, there's a shabby but intact plastic mat folded up on the walls around the washing machine/drain. I'd prefer to keep the plastic mat as a moisture barrier (and save some work). Ideally, I'd like to raise the floor about 15mm from the current level to match the connecting floor properly. However, there's a recessed floor drain that complicates things a bit. It's also worth mentioning that it sometimes overflows.

Alternative 1? - Tiles directly on the plastic mat
From what I understand, it works, but I won't reach 15 mm. Is that correct?
Does anyone know how I can solve it at the floor drain?

Alternative 2? - Renovation plasterboard 6mm and then tiles
I reach about 15 mm! Great, but...
Since there's a risk of flooding, plasterboard might not be the best idea. Can this be solved in a good way? Plasterboard + moisture barrier + tiles???
How do you solve this at the floor drain???

Grateful for feedback and ideas.

I think it now counts as a wet area. Industry regulations ...

I wouldn't be surprised if you need to replace the drain and remove the plastic.

Otherwise, extension ring + leveling compound + the rest...

But not renovation gypsum at 6mm. It's for walls.
 
Oh oh...

I haven't read the branch regulations yet but looked a bit in other threads. There they mention that there should be 5 (or 10cm) of sealing layer up on the walls. But how far from the floor drain does it need to be moisture-proofed?

As I have it, the washing machine/drain and kitchen are in the same room and I have no desire to moisture-proof the entire kitchen or have ledges/threshholds in the middle of the room.

How should I do it and how much do I have to do?

This is what it looks like today.

Along one wall, the plastic mat is folded up 10cm. Otherwise, no barrier up on the walls.

Is this a solution I can continue with?
 
YOU have to wait until someone more knowledgeable looks at it.
I'm not going to guess.
