So firstly you will need to get a place where you want to put this pool; when you have the location you will need to dig a shallow pit of around eight feet square and it will need to be very deep, around twelve inches. Try to get this as deep as you can and make sure that the bottom of this is firm but smooth.
Now you will have to build your pool frame, you will need to take your four pieces of wood – they should measure out to four by four and cut the end of each pieces of wood – though remember to only cut one end of each piece of wood. Make sure the cut is a forty five degree angle, one of marine plywood and four by four will need to be attached together, so nail this together. You will need to continue your pieces of wood together to create your frame which needs to be sealed before any water is added.
Now take your frame and place this into the hole and try to put this as far down into the hole as possible, remember that the four by four ends which you cut must be facing upwards. Of course you might find there is one or two gaps in the frame or between the frame so take some soil and fill in any gaps.
You will need to fill the pool in with sand, almost two inches of sand which acts like a layer on the bottom of the hole you dug. Make sure that the sand is level before you carry on and put your plastic sheet over your frame; press this completely into the pit on top of the sand so that you have got a liner. Try to make sure this is completely smooth and has no wrinkles in this so that you can get a perfect liner at the bottom.
To secure your liner, you will need to pour some sand over your plastic sheeting; you can now fill your pool in and you should find that you have got a good wading pool. Though remember that to empty the water you should a submersible pump when you need to change the water.
When it comes to your filtration until then you should think about installing this somewhere near your pool so that you will have not one but two pipes going straight into the pool. That will mean that there are now two pipes, one of them will be for the output of the pool and one for the intake for the pool; creating a homemade filter might be the best option. This would be best to build from filter cotton or sand cotton also but this keeps the pool water clean and tidy.
