The one we are looking at has a hot tub that currently retails at £15k. It also has a sauna. Both two years old. We will probably spend a lot of time touring the area, so relaxing in it in the evening is quite appealing really.We've been thinking about one, with a sauna and a plunge pool. But that's mostly for winter use - in my head anyway. If you're going to be active during the day skiing, cycling, and the like then they're a nice way to relax.
A 6 seater with a wood burner for heating start at about 3-4k over here. That's quite a bit less than 10K.
We are looking to buy in North Yorkshire. I'll probably start another thread asking for tips on good places to visit over there.
