We have a copper bath (bought on eBay at vastly reduced price!!). It is enormous and I absolutely love it. Most def big enough for 2
! It is very very deep, so if you sit upright in it, water comes up to just below my shoulders, totally covers boobs. OH is 6ft 5 and fits no problem- he loves it too.
In terms of how much I'd recommend, 2 things...1) I had a homebirth with my first, and am planning with my 2nd - it's so large I haven't bothered hiring a birthing pool. It's that fab. 2) we are rapidly outgrowing this house, already have new house (huuuuuge renovation project) and I won't compromise on bath size, it has to be this big (at least for the adult bathroom). I'm searching eBay regularly in preparation!
Negatives: 1) it is expensive to fill. We have a good combi boiler and it doesn't struggle at all, takes about 30 mins to fill. On the other hand, it stays hot for over 2 hours, I go first, then dd 18 months joins me for 15 mins, then oh has it. So if you do water sharing doesn't have to be crazy expensive. 2) it is HUGE. We live in a 1700s house and it had to go in through the roof when we had it off as it wouldn't fit up the narrow staircase ( bathroom is in the eaves so it just went straight in). You need quite a big bathroom so it doesn't look ridiculous 3) even if you get an eBay bargain it is expensive...
Yes, if you love baths, I couldn't recommend enough!
