I am doing a lot of refurbishment at the moment and am thinking of saving money by buying a shower cubicle on ebay.There seem to be 2 types available-a curved area inside or a square lip.Does anyone know the pros and cons of each model?.The bathroom has space for a 1400 by 900 or a 1400 by 800.Secondly do these walk-in designs stop water getting on the floor or am i better getting a fully sealed design.This bathroom is off the study and is also the downstairs toilet.Hence a wet floor is not a good idea.Any feedback would be incredibly helpful as i have virtually no time to look arround in r.l.
