A big Hot Tub in the shape of a heart usually used for four people, that could end up doing something naughty.
1: Are you going over to my bro's house he has a love tub
2: Yeah man definitely you never know what could happen in a love tub!

I noticed the wife had run herself a bath so whilst she was getting something in the other room I quickly nipped in and wanked into it to give her a love tub.
