Dh says we should have 1 of each for back up if boiler breaks and so hot water isn’t used up however we’re a family of 3 adults in a 4 bed house that shower at different times.Sometimes have another sibling staying. I see his point though.
For context I love the tongue and groove older style of bathroom and can’t find an electric shower that I don’t hate( ugly plastic or metallic boxes with heads I wouldn’t choose).
But will I regret 2 pump showers?Currently living with just 1 pump between the 3 of us and it’s fine.
