We had one of these for over 2 years.

Takes 2 people to assemble and some parts were cumbersome to handle. Saying that my wife and I managed to erect it over 2 days and she is limited in her movements due to disability.
The first thing is to prepare the ground. It MUST be flat and even with no stones, twigs or any other possible sharp objects likely to come to the surface once the pool is erected.
You will also need a filtration/circulation pump, and of course a heater. You will also need a ladder to get in and out by which must not rest against the side or on the top. Suitable ones are available but I will point out a potential fault with them further down.
They hold almost 20,000 litres so if you are on a water meter you will need to consider the cost of filling/topping up in your overall costings. (Unless you have a friend in the fire brigade,
)
Electric heaters are prohibitively expensive and will not heat the water to a comfortable degree to remain in for very long. Our initial heater struggled to get it just over 20C Public baths are normally 27-30C We eventually bought an 'Air Heater'. They work on the reverse principal of a fridge by drawing in outside air, (regardless of temperature), and heat it up instead of cooling it down. As an example, when using the electric heater which was 2.8kw, our overall electric bill for one week was roughly £97. After fitting the Air Heater a comparison reading gave us a bill of just over £41 for the week and the water temperature was in the low to mid 30'sC
A disadvantage of these large pools is the water input and output through the skimmer are near the top. As hot water, like air, rises then the upper warm water was circulating back to the heater leaving the lower cold level to just circulate in the pool. We used to 'stir' it up with a couple of paddles to even the temperature out before getting in.
You will also need to treat the water to maintain the chlorine, PH and alkalinity levels plus the test strips to measure them. We had a very large, (8mtr x 4mtr), gazebo/marquee over ours to keep the flies and wasps at bay. It's amazing how they all seek out a large body of water despite the chemicals in it. You will need a net to skim those that do get in and land on the water and a hand suction vacuum type of kit to collect any that drop to the bottom.
Finally the ladder. We originally had an 'up and over' style with spread feet but despite this it put indentations in the pool floor and we had to move it around every so often to try and prevent tears in the fabric. I ended up building my own steps with a broad flat foot to prevent this.
I'm not trying to put you off but they are expensive to set up correctly and need regular maintenance to be worthwhile. You must NEVER sit on the top lip or kick away from the sides or you are in danger of disastrous results if it collapses. 20,000 litres will have some force behind it if released suddenly and spread over a very large area quickly.
Sadly we had to dismantle ours after an 'accident' by a relative. Said relative agreed to pop in and check it every other day and make sure water levels were ok and all electrics were still functioning. Unfortunately he dropped his watch in and tried to fish it out with a hooked length of wire. Dragging it up the side he never noticed he put a small tear in the liner. Thankfully it didn't burst but overnight the levels dropped and damaged the pump and heater. We could have replaced them and attempted a liner repair but decided we didn't have the enthusiasm.
Research and cost it thoroughly before 'splashing' out. Make sure you have taken everything into account first.
By the way, they take up a very large part of your garden so measure and mark out the area the pool and it's accessories will occupy.
