If you are searching for the right hot tub (ג׳קוזי) let me suggest one made from cedar. Cedar is a tree of the coniferous family and is closely related to the fir tree. The cedar tree can be found in the Mediterranean region, Western Himalayas and in much of North America. Cedar is very resistant to decay and is a very good type of wood to use when building anything that needs to last for a long time. The wood is also resilient to weather. Many closets and chests are made from cedar because of this reason and also because it is said that cedar wards off moths. Cedar is definitely prime wood and a hot tub made from it is sure to be extremely beautiful and enjoyable.
Another reason to get a cedar hot tub is because the coloring of the wood is very beautiful and many people love it for that reason alone. Manufacturers of spa tubs are really impressed by the woods potential. Tubs that are made from cedar are in great demand and very popular. Also the availability of cedar tubs (בריכות ספא) is really large. Most manufacturers make it a point to have wood tubs built because they know that the cedar is one of the most popular materials to use when building a spa tub. Even the Internet is littered with spa manufacturers selling cedar units to the public, so finding the perfect one should be really easy.
Therefore, any reason that I have given above is a good reason alone to buy a cedar hot tub. The natural golden brown coloration of the wood will make the area you put the tub in will have an instant naturalistic feel to it and help you feel closer to nature. However, it does not mean that just because it has a natural feel to it that the tub is old fashioned. Most of the spa pools (ג׳קוזי) build in modern times have many excellent features like massage jets and temperature gages to make sure the water stays nice and warm no matter how cold it is outside.
