Thought that heat lamps might get rid of the chill factor?

I have 3+ meter ceilings in all rooms including the bathroom, and the heat lamps are a godsend in winter.

I’m looking to renovate the bathroom over the coming years and thought that an open space shower might be a great addition but maybe we will reconsider.

I do like the Japanese prefab wet bathroom units, but not sure if they are available here, nor if the other half would approve.
