We have an existing shower in what I suppose you might call a changing room next to a bedroom, it makes the bedroom 'en-suite' (there's a wash basin and a loo there too) but has never been satisfactorily waterproof.
Can anyone recommend a shower unit that is genuinely waterproof all round? The shower is currently installed against a wall on one side but it's just a dry-lined wall with pine cladding so is neither smooth nor water resistant. We need a shower that is fully watertight on all sides without any help from adjacent walls etc.
