thanks willy - appreciate it. We are meant to be moving house on the 21st, my MIL desperately needs a wet room as the council have said it’ll take a year... and I’ve been asking questions for my OH who is doing it, but obviously I’ve sometimes been repeating myself, or he hasn’t taken advice of some people (Jord) as some issues weren’t addressed (I’ve spoken to carpenters elsewhere who disagreed with him and said 2x4s should never be used, joists should always be drilled centre of brick), etc, and we screwed up with how high the joists were and taking them down was borderline impossible as the 18mm holes were so tight (why they say 16mm bolt with 18mm is beyond me as it just seems super tight) but we got it in anyway!
to get them out we would have probably have to knock the bathroom down and yes, we were both exhausted from this.
if anything, the next bit is quite simple. Stud wall, backer board, lay down chipboard 22m flooring, fit impey 22mm shower tray, tank, adhesive, tiles.
the only challenging bit from all that is to layout the plumbing but even that isn’t too hard. We were hoping the floor was fine and there was no asbestos but both initially didn’t turn out to be true so we both were knackered when it came to the floor!
we’ve both rested today, so onwards and upwards - won’t let the negativity of some on the forum bring me down. You’d think there would be some humility when someone is asking too much or repetitively. There’s usually a good reason I.e forgetfulness, exhaustion, I haven’t posted all the caveats, etc.
whatever, life is too short and I appreciate all the good responses anyway
