I called the Hydra Pool manufacturer about this, and was told that the bottom was mainly a builder's preference. Some do more of one or the other. According to Hydra, we will not notice any pros or cons with either bottom. I am wondering if anyone disagrees?

If you could post a link to the actual drawings that would help. I can't get anything to come up at hydrapools.com

The two bottoms that I am comparing are the 40'6 x20'6 grecian square bottom and the same pool w/ the contour bottom. You have to pick each one individually from the list on the page that I pasted above. What you will view is the dig diagram of each type. Thanks, Webfeet

I looked at the drawings you are talking about. They do not have a straight 8' drop. They have the angled hoper like other vinyl pools.

If you look at the small drawings it shows the angles.

GG, now I see that neither style have a sheer drop. However, I still don't know if one is more desirable than the other for a particular application. I finally called Hydra, and they say there is no noticable difference to the swimmer. I was just wondering if any vinyl pool owners or pool installers had any insight. Thanks.

I hesitated to reply since I'm not an expert, but I do know that when we put in our vermiculite/cement sides and bottom, the angle on the walls and hopper sides made it easier to to lay down the mixture. The mixture has to be just the right consistency, and it has to go down pretty quickly or else it won't adhere to the dirt base or it will just slide down.

The straighter the walls, the more gravity will pull down the vermiculite/cement mixture, the harder for it to stay where the installer puts it.

We have a 10.5' deep end, and the angles are fine. Jo
