NR £6k for a new fitted bathroom is more than a bit rich IMHO. You should be able to find a reasonable plumber and tiler locally who's rates are more reasonable than those offered by the Bath store.

If you are just re-fitting your bathroom and freshening it up with new tiles, the install of the new basin, bath shower etc should be a fairly simple swap-out. Just copy what was already there.

If that's the case, you ought to be able to do that bit yourself, and then employ a tiler to do his stuff. Learning to do the plumbing yourself will be a very useful prep.
