Hot Tubs and Spas
Bring the Olympic Experience Indoors
Indoor Spa Installation
If you don’t have a spot for your hot tub outdoors, or you want to relax and soak in the interior surroundings of your home, bring the Olympic experience indoors with an indoor spa. Keep in mind that installation of an indoor hot tub involves different considerations from an outdoor hot tub. The following review covers special concerns regarding indoor installation of a Hot Spring™ or Hot Spot™ Spa.
TIP: Consulting with a qualified builder or architect is highly recommended. Most hot tubs go outdoors, but an indoor installation will suit the needs of some hot tub owners. And, if you are building a new room, make sure you leave ample opening for delivery of the spa!
Avoid slippery, slick floors. A typical bather takes up to a gallon of water with him when getting out of the spa. Choose a floor material that offers good traction and drainage when wet. Do not install wood floors or carpeting. Carpeting may feel nice but can mildew and rot. Also, avoid “Astroturf”/plastic grass carpet, because water tends to seep under it and cause rot. A matte finish, non-slip tile is preferable.
TIP: Install a floor drain for easy clean up and draining the spa.
Even though all Hot Spring and Hot Spot Spas are portable and require no external plumbing, you’ll need a convenient water source for filling.
TIP: Install a hose bib in the room to make those fill-ups easy.
With the spa cover off, the room will become humid and steamy very quickly. However, with the cover on, there is no moisture emitted from the spa. So, certain types of wall coverings are better than others in a spa room. Cement walls, glass enclosures or cedar-lined room are some examples. Drywall must be the water-resistant type used for bathrooms and kitchens.
TIP: An intact vapor barrier under the wall covering is a must to help prevent dry rot of studs and joists.
A vent fan must be powerful enough to take moisture from the room quickly and quiet enough so that you’ll use it, The typical “builders special" vent fan is very noisy and will rust quickly, staining walls or ceilings. The fan you choose is the most important element in saving walls and structural elements from dry rot. We recommend the Vent Axia brand fan available from Coast Products, 954 Elliott Avenue West, Seattle 98119, (206) 285-5120. Vent Axia fans are whisper quiet, won’t rust and are sized to the cubic feet of your room, They’re available as ceiling, external wall or window mounts. The T-series features a timer, thermostat and humidistat in one unit.
TIP: Consult an HVAC contractor for the best place to position the fan in the room.
To minimize moisture collection, make sure that the room is heated.
TIP: A ceiling fan will help with air circulation.
