Hi, I have in my house a Partner system I have always had a cheapo phone in the master bathroom for those calls that you just cant miss ( when you not to busy) and if their ever happens to be the need to call out ( im thinking if there is ever any emerg.) anyway . I put an 18 button set in their. but not so sure how it will hold up. The room is somewhat large but has dividing walls and I have not yet go around to putting in the exaust fan. I want to put a set in with an LCD screen. But I think the moisture will get to it. and i dont want to mount an outdoor phone box to house it it( this is what an online company said to do) Thanks for any advice you can give. Jake
