Well, their website is atrocious for the public. Only stockists are Travis Perkins builders merchant.
There are literally hundreds of other range/manufacturers to choose from.
Tell us what area you live in as there maybe somebody local who can give you some advice on a local supplier.
I have been in the bathroom trade for 30 years, iflo looks no different than any.
Please describe what you want and how much you are prepared to spend as that is the 1st thing you want to know as well as the the fitter/supplier.
edit.....as per the norm....there will now follow a debate on various folks experiences with every bathroom supplier known to man. The conclusion will be...that you still have to make your own mind up. Good luck but please add as much info for the pro's as possible, it will save multiple answers or questions trying to find out the same point.
