There are several different types of hot tubs and they all have their own advantages and disadvantages, which we will discuss here.
In-ground hot tubs - They are by definition in general, built in to the ground.
This means that you will have to have a large whole dug into the ground to put one in to.
They are commonly made up of a concrete floor and walls made up of blocks.
All of these will then be tiled over to give a very professional looking spa.
However most of these tasks will need to be carried out by a professional contractor, and as a result they are the most costly to install.
Also you cannot take them with you when you move house.
Acrylic tubs - These are mass manufactured in a variety of sizes from two seats to twelve, or even fourteen seats.
However this means they are bulky and whilst you may have room to site one in your garden, you may not have room to actually get one in to your back garden without the use of a crane to get it in to place.
This can be a major expense and is often overlooked.
Many acrylic tubs are now being produced with self-cleaning mechanisms meaning that you only have to top up a chemical reservoir each week, rather than test the water daily.
You can also take them with you if you move house.
Cedar wood hot tubs - These are cheap, however you will have to build them up yourselves, but the competent DIY person should be able to do this easily.
They only take up a little space, and can also be taken with you if you move.
