Since my wife had a stroke, I have installed a walk in bath. I have a bad back and prefer to have a bath mostly,however my wife can only shower.We have a combi boiler and both bath and shower work extremely well.The bath is absolutely standard, full size with the exception of the walk in door.We do not have any leakage problems with the door even when the bath is full, when showering the water just runs away down the plughole.I do not have to sit in the bath to wait for it to empty, I climb in and out as one would do with a standard bath and then allow the bath to empty.Although the bath cost just over ?1,000.00 plus installation, for us it has been the ideal solution and has been in use for over six months,without any problems whatsoever.
