I'd love an extra minute in the shower..

..or at least my wife would!  I don't really dilly dally when it comes to showing in our caravan and I'm usually in and out before the hot water runs cold.  But my wife would like a little longer to condition, exfoliate, or whatever she does! So, apart from
spending A LOT of money on a 14 litre hot water storage tank, is there any way of getting more time in a hot shower? Or do I just send her to the shower block
