@markmarshalllsh: Is concrete a good base for your hot tub? People have been using hot tubs for decades, as a building material it will do the job well and will require some planning to create the right frame for your tub to sit on. You will need to dig down around 125mm and make the plot larger than the hot tub itself - a good 12” around the tub will suffice. If you plan to do a base for a Swim Spa this may require some additional strengthening in the concrete pour. Once you have dug out your plot and placed a layer of gravel in the base, you are ready to pour. This can be delivered to your house ready to go, or you can hire a cement mixer and do it yourself. The part you need to pay most attention to is after the pour use a leveller to make sure the cement is level and flat, then when dry will be set ready to go. #base #concrete #hottub #fyp
