Hot tub cottage or similar recommendations

[Matildahoney]

I'm looking for recommendations of any decent UK accommodation with a private hot tub, not too pricey, preferably romantic, more importantly relaxing, and not too far north as it may only end up being a few nights. I'm about as South as you can get. TIA.

The lake house at settle in Norfolk is really romantic

Wattisham Hall or Woodfarm Barns in Suffolk

One of the shepherds huts at The Fish in the Cotswolds or Bethnal & Bec in Hertfordshire
