• Does anyone have any ideas as to why my cold water bath tap is luke warm and the bathroom sink that sits relatively close to it is ‘normal’ cold? It’s not a major issue, but my flatmate/tenant loves an ice bath and it isn’t an option.
    I can only think that the pipes are being warmed by proximity to the boiler, but it isn’t even that close.

  • Do you have a cold water tank and possibly the bathroom sink is connected to the mains to avoid pollution from the tank in what could be considered drinking water. As far as I know kitchen sinks are supplied from the mains for this reason.

  • Could be piped wrong, proximity to the boiler won't affect cold main temp. You'd need to know what kind of system you have.

    If you have a combi fitted i'll bet you won't have a tank and even if you did have a tank for your cold water supply that supplied the bathroom it'll be too big to get heated from proximity to something unless as ive said its piped wrong.

  • Cold tank maybe as mentioned above.

    What's the water pressure like on the sink compared to the bath? I had lousy cold water pressure from the cold tank compared to mains-fed.
