I don't know if this is the right place to post this. We currently have a large single person Jacuzzi tub in our master bath room. We are going to replace it with a whirlpool hot tub / spa. We are looking at tow types. The first is a corner mounted drop in hot tub more in line with a regular soaker type tub. The second is to go with a more conventional hot tub/spa. either of these will be small, the available space is 65" by 84". One of my concerns with the contential hot tub/spa is that these are normally left with water in them. For this type we will definitely be using a cover. Will humidity be an issue? Has anyone experience with the builtin corner type hot tubs?
