How much for en-suite?

tonybobs

Hi all,
I have a 3 bed bungalow with only one bathroom which can be a nuisance at times. ( Such as yesterday when I was parked on the throne and my OH was hopping around outside telling me to hurry up!)
My bathroom backs onto my bedroom and I have 2 double fitted wardrobes with sliding glass doors so the plumbing work should be simple.
Now, I would like to have one of the fitted wardrobes taken out to make into an en-suite. Just a toilet and sink.

Could anyone please give me an idea of how much the whole thing should cost?

Thanks ever so much in advance!
