Any recommendations for places with hot tubs for a weekend in the south of England in March?

Has anyone been to a nice house/cottage/chalet/B&B/hotel with a hot tub (if possible) you'd recommend? Some friends have been having a rough time recently and we've been daydreaming about escaping for a weekend and doing not very much. We don't want to have to travel too far - we're in Hampshire and will go to the next county or two in any direction. 5 40-something women. Looking for quiet and comfy rather than a hen do place.

Any ideas?

There’s some nice hot tub accommodation at Wallops Wood Cottages, but that might be a little too close to home! Also, I think they do a minimum stay of 3 nights unfortunately. Ditto for Blackwood Forest.
The Victorian Barn in Dorset is a cottage complex with an indoor heated pool and sauna. Some of the cottages have their own hot tubs but I’m not sure about a minimum stay.

I'll check those out, thank you - not heard of any of them so this is a new seam for me to mine.

Burnbake in Dorset is gorgeous. Inbetween Corfe and Studland Bay. One of The Pig restaurants nearby if you fancy treating yourself.
