Vapour barrier in bathroom?

[stoobloo]

I’ll be renovating a 60’s bathroom soon and am looking at using 10mm insulated backer boards to increase the thermal properties of the room as a towel rail and need to vent the window after showers and baths means it’s never the warmest room!

Is a vapour barrier advisable, or could that cause other issues around the house further down the line?

60’s built house, cavity wall with insulation, bathroom is north facing end of house.

10mm backer while better than nothing is not going to make a massive difference. Having said that. I did the same recently and also attached using plasterboard foam as well as screws, mainly because half the wall plaster came down with the tiles. I made sure all the joins were sealed with foam. I also put some loft roll in a service false wall where the shower is and it's Pretty good.

I also installed the 600 x 1800 of these:
