If you are considering installing a hot tub in a sunroom, there are a few things that you need to keep in mind during both the planning and construction stages. You will need to make sure that you have enough room to accommodate a hot tub, and privacy concerns need to be addressed. By planning ahead, a majority of possible problems associated with installing a hot tub in a sunroom can be solved before the installation gets underway.
Installing a hot tub in a sunroom will require quite a bit of space. Not only will you need to calculate for the hot tub itself, but you should also keep in mind that ample access is available. It is a good idea to provide at least 3 feet of perimeter space around the outside of the hot tub. If you will be using a sunken hot tub which is approximately level with the floor a majority of the machinery can be hidden away beneath the decking.
You will need to get water into the hot tub, but keep in mind that the water has come back out again. The drain will need to be situated high enough that a constant fall of at least 1/2 inch is available for every 4 feet of drain pipe. For optimum drainage, allow for more fall, with 1 inch of fall for every 4 feet of horizontal pipe being the suggested slope.
A sunroom hot tub has quite a bit of exposure. Be sure to make allowance for your privacy, and the privacy your neighbors deserve. If a wooden fence is not high enough to provide ample visual protection, consider hanging blinds along the walls where line of sight needs to be obstructed. For a more natural solution, line the walls with thick foliage, and possibly plant evergreen trees or shrubs around the perimeter.
Plan your electrical access carefully. A good rule of thumb is to provide a dedicated circuit for the hot tub, and to keep other electrical circuits safely away from the tub. There is no way to avoid a certain amount of water being splashed about from time time, so make sure that fans, stereos and other electronic devices are situated safely away from the area where they may be inadvertently exposed to standing water. If available space is at a premium, consider installing electrical outlets higher off the floor and using waterproof electrical boxes where possible.
Plan for guests and the things they will require. If enough space is available, a changing room is a wonderful idea. It doesn't have to be built from heavy materials, but could easily be created using sliding glass doors, or even well-hung shower curtains. Another excellent idea is to hang horizontal blinds that can be lowered when the privacy is required, or rolled up near the ceiling when the dedicated area is not needed. A convertible changing room of this type is an innovative way to provide for guests without having to completely remodel your sunroom.
