Excellent responses people! All those great house design ideas that I never thought of. Pity I got nuthin', but a few other design masterpieces....video....the space shuttle......the apple macintosh...the cellphone, but never mind all that...leg warmers and MacGyver, woohoo. Or perhaps..... Metallica, Kill 'em All. Oh yes please.

Before replacing your curtains as this can be quite expensive for such a large window, if they are in good condition, add a band of extra fabric to the bottom in what ever suits you, your existing curtain track can then be moved up to the ceiling for good looking full length curtains without the large round eyelets, could save you a lot of money, I would look at replacing/removing the sheers cheers

Attach are photos. I have been told by 3 different bathroom / plumbing co's it is not mould. They have scraped out some grout, put new grout in & the dark stain has come through again. The builders warranty expired Nov 2015. The builder passed away about a year ago but his wife is still alive & she was co-builder / co-vendor. But, as I'm out of warranty not sure if I have a leg to stand on. It has been suggested that the experts scrape out all the grout, silicon the bit where the stains are & re-grout & maybe the rusty nail stain doesn't break through the silicon / new grout. Can the wrong nails be used in wet rooms that has therefore rusted? Is there normally special nails for wet rooms? Has anyone heard of a 10 year builders warranty - standards & tolerances - for major defects; possibly like this? Thank You. It's very annoying I must say.

Thank you everyone, lots of food for thought. oklouise, would you have the false wall going all the way along the bathroom or just jutting out behind the vanity? We have a few cm to work with as the vanity we are looking at is a little narrower than it could be. jacqueline thank you so much for your photo! Something that goes down a bit lower might help disguise the pipes, ours will be a much smaller room than yours. siriskey, I have attached the plan for this room to see if it is helpful. I am leaning towards choosing a different vanity but as you have said this one is lovely! But it won't be lovely if it doesn't work...!
