Complete floor joists to 30cc

[Blonda_Marri]

Hello,

Suggestions on how to easily complement existing 60cc studs to 30cc?

Do I need to complement with the same dimensions as the existing studs, or can I manage with a smaller dimension?
The length of the studs to be complemented is 3.50m.

It's for an Älvsbyhus from '91 with a crawl space foundation.
How do you experienced ones do it, and what do today's building regulations say?

Thanks in advance!

For what reason should you reduce the measurement?

An old bedroom is going to be converted into a bathroom and we need to install tiles, I have heard that you need to have cc30.

Check with the person who will build the bathroom first so you know what you should do.

I already have a company that will do the waterproofing and they say cc30. But the framing is something we need to handle ourselves and I'm considering which method is easiest for someone who hasn't done it before.

Same dimension as existing reglar.
