Shower hoses for home come in various lengths and bore size. I would suggest that you remove the old one and take it with you to somewhere like Screwfix and you can then match it up size wise including the size of the fitting on each end. A quick look in Screwfix gives 13 different hoses.Toolstation also stock 5 different ones.
They are the same screw fitting as I have one of the caravan shower heads in the bathroom at home!!!Ours in the Motorhome is a bit shorter probably 1.5mts. I need to get a new hose as metal spiral keeps coming out of its fixing.
