On checking it appears to be a Coast 'Northwinds' model, if your interested I found it on the Coast Spa UK website here where you can find the full spec of the tub and options available. My only concern with this model is the limited options and spec available.
I don't know the price it is but it might be worth looking at the similarly layed out Vantage 45 which has a much better spec and options.
Vantage
Hope this helps.
P.S.
Don't limit yourself to one brand or model, test as many as you can and find one that suits you and the family as a whole, plus check out the dealer as not all are the same.
