^ For balance, I'm 5'11" and have a 1600 bath, but it's as deep as a deep thing & is great. I'd advise on spending on a good quality one though; Carron do a few 1600 options if you go down that route.
Shop about a lot as well; quality internet offerings are sparse. I ended up with a Hudson Reed ex-display in a local independent store for a bargain price.
Also Google outtasight shower screens to maximise space; relatively unknown little gems.
