Waterproofing mobile home

[Villavagnen på landet]

Has anyone here installed waterproofing membranes and self-leveling compound in a mobile home? We need to fix the shower/laundry room but are afraid it might crack when we move the mobile home. The plan is to move it once more in a few years, but we will be living in it year-round starting this year.

We have also looked at floor drain alternatives because the shower's floor drain will be under the cabin (the floor consists of 2 layers of particleboard and 90 mm insulation) and we are worried it might freeze during winter.

Grateful for any suggestions!

The best option should be to invest in a flexible waterproofing layer that is also visible if you are concerned about movement: i.e., wet room mat and wet room wallpaper?
That way, you can see if something breaks. And if any self-leveling compound underneath cracks slightly, it probably doesn't matter much.

Regarding the floor drain freezing: You can make sure to empty the water trap before winter and possibly seal it with some kind of lid (against odor) if you are worried about that? There won't be water in the drain afterwards (at least not enough to freeze it).

It's probably more complicated with mixers and the water piping in the shower/laundry room - you need to ensure you can drain all the water: For instance, have a lowest point for draining and possibly a compressed air nipple to blow it out.

Regarding the floor drain freezing: You can make sure to empty the water trap before winter, and possibly seal it with some kind of lid (against the smell) if you're worried about that? There won't be water standing in the drain afterwards (at least not enough to freeze and break it).

It's probably trickier with the mixer and water lines in the shower/laundry room – there you need to make sure to drain all the water: For example, have a lowest point for draining and possibly a compressed air valve to blow it out

Yes, it will probably be wet room mat, but we'll be living in it year-round so we can't empty the water trap in the winter unless you want to live with the drain smell?

Well, it will probably be a waterproof floor, but we will live in it year-round so we can't empty the water traps etc. in the winter unless we want to live with the smell of sewage?

But if you live in it, it is heated and water will regularly flow through the drain, right?
Then it should be enough to insulate underneath and possibly the pipes above ground...

That way, you can at least see if something gets damaged. And if the leveling compound underneath cracks a little, it probably doesn't matter that much.

Regarding the floor drain freezing: You can make sure to empty the water trap before winter, and possibly cover it with some kind of lid (to prevent odor) if you're worried about that? There won't be water standing in the drain afterward (at least not enough to freeze and break it).

It's probably more complicated with mixers and water pipes in the shower/laundry room - you need to make sure you can get all the water out: for example, have a low point for drainage and possibly an air fitting to blow it out.

I have now lived in my mobile home for a year. I have insulation and heating cables around water and sewer pipes. It worked fine.
