How do I bathroom / kitchen / extension? etc.

Fox had an infamous micro-cement onsen

I think quotes came in about £140 m/2 when we looked. If you mean microcement?

We didn’t go for it in the end. Wished we had, but we’re moving again now so shrug

I really like this shower/bathroom anyone got any experience with this type of thing?

Sounds similar to this
