Our bathroom is really rubbish and we're just about to spend a stupid
amount of money on doing it up; around £10,000.

Hope you plan on living there for while......

Any ideas on how much this would actually add in value to a house?

a lot less than 10 grand. Assuming a really crap bathroom like we had -
very scruffy, stained, dreadful pink colour, totally crap over bath
shower. etc. then I imagine that it might add a couple of grand if you
are lucky. but as has been said, much depends on the property etc.
However, more importantly I think, it will increase the saleability if
the house. A crap bathroom will put some buyers off which a decent
bathroom might otherwise attract. But a 10 grand bathroom won't increase
the saleability 3 times more than 3 grand one.

IMO, if you will probably be selling in the relatively (within say 3-4
years) then I would consider if the benefit of the useage and pleasure
you will get for those few years is worth the money it will cost ,
bearing in mind you won't get most of it back on sale. But if you plan
on living in the house for another 15 years say, go for whatever you
feel is worth it, it'll be pretty irrelevant in 15 years time.
