Humidity can be controlled with exhaust fans. Over time there may be problems with staining on sheet rock and stuff. But if you controll the steam it can be done. More important is draining, theres almost always splash. And what about draining the tub, do they have that covered? Getting it out or a new one in.....yea good one, between 2 windows and some demo and concrete patch. It's funny they don't just support the upper floor on both sides and make the removable area wood, or doors. But it can and obviously was done. If it's a good quality tub it should last 15-20 years so it's not like you have to do it that often. I'd have to look at it to give you an idea of what I would charge to do it. I have done it before but it was a walkout that we removed the sliding glass door to accomplish it.
Next question for you is why? The stars at night are awsome from a 102 degree tub!
Thanks for responding. I'm not really sure how to use this site, so I hope I'm doing it right.
There are no fans in the basement at this time. Draining is not a problem. They have a sump pump to drain into. I'm not sure what you meant by "It's funny they don't just support the upper floor on both sides and make the removable area wood, or doors. But it can and obviously was done. " The hot tub seems to be on a platform of some sort, but that's all. The floor underneath is tile and has some stains around the tub (rust???) I'd love to have it outside, but we are trying to keep our costs down and I think building the platform outside, replumbing & rewiring, then addding a privacy fence is more than what we want to incur at this time.
