Plenty of water in the cafeteria and the restaurant and the water from the taps in the cabins is completely potable. You can buy water if you like or just refill your own containers as and when although they do not like you to do it yourself from the cafeteria supply point for health reasons, you either take a glass full and pour that into your container or ask one of the stewards. ....

Thank you and I love the name of your address, it's better than mine. ... Neil.
Believe me you do not want to drink from the tap!!
Drinking from the tap is fine but as most ships make their water from seawater via a desalination plant it is more salty than 'normal' water. If your doctor has told you not to take salt or you have high blood pressure, I think it may be unwise to drink from the bathroom taps. Check whether the taps in the buffets are also 'ships desalinated water'. I usually buy water in port and take into the cabin. thats one thing they wont take off you !! When I arrive in S'oton I board with 2 X 5litre bottles plus a six pack of 1/2 litre bottles.
