inground pool shape - which is more practical?

[pool123]

I have a concrete floor with vermiculite slopes. The vermiculite needs repair after a winter without a liner. It also makes complicated to measure the right size for the liner replacement.

Is there any practical reason to have the shape A instead of the shape B?

Is it a good idea to remove those vermiculite slopes and make it straight rectangle as in the shape B?

I have pool A. The practical side is that it is a bit easier to hang out in the deep end, as you can use the slope for your feet (you still need to hold on to side, just less pressure on your arms). The only other advantage is that A is a smaller volume of water to take care of with chemicals...

I think it would depend on what is under the vermiculite. Might be a real mess digging it out.

It also makes complicated to measure the right size for the liner replacement.

Any good (note I said good) liner replacement company can measure A, no problem. There are 100s of thousands of A shaped pools.

I would say I always hit these slopes with my feet. It makes deeper (6') part of the pool smaller but I am tall. Kids probably have easier time with it.

I would guess that the builder made a concrete floor first and then rounded corners with vermiculite.

I had 2 guys measuring the liner's size with different numbers. I also did it twice. How forgettable are the errors with liner's measurements? I would guess that the shape A should form less wrinkles as less 90 degree "sharp"angles.

I am no pool or liner expert, I'm a mechanical engineer.

I can see for pool A the liner measuring and manufacturing is a lot more forgiving than for B.

If you want B, I would say put a 6" to 12" chamfers is the corners (where wall meet and where the walls and floor meet). If you don't do it where the walls meet, you will likely have to deal with the liner coming out of the liner track in the corners over time. Usually liners are bit smaller than the pool so there are no wrinkles, how much smaller is a factor of what the temperature will be when the liner is installed.

I have a pool A hopper. Given that the pool was structurally designed with those slopes, I would keep them in. You never know what might happen structurally if you remove them. Plus;

There are 100s of thousands of A shaped pools.

Assuming you have a steel walled, vinyl liner pool, with a concrete floor and vermiculite slopes, I don't think I've ever seen a steel walled pool hopper like B.

I have plastic walls.

Plastic/polymer, steel are all about the same. Your plastic is polymer right, not some new type of plastic wall? Regardless, I’d stick with hopper A and the slopes.
