Changing Pool Size

by Tina Jones

A friend gave us an above ground 33' x 52" round pool. There are some parts missing, like 2 bottom bases.

Can we turn this size pool into a 27' x 52" by decreasing it due to we are missing some parts and we can not find replacement parts anywhere.

Thanks!
Any input will be helpful.



Hi Tina. You should be able to convert the pool. I usually recommend ordering a new set of bottom rails because the arc is slightly different between a 33' and a 27'. The difference is so small that you might be OK using the ones you have.

You could start by laying out the bottom rails and start connecting them using a tape measure and setting the radius at 13' 6". Hopefully when you get back to the beginning you will meet up with an open footplate, and not in the middle of the beginning rail. It should work out that you wind up close to the 27' round mark by just removing a couple of rails.

Most top rails are made with multiple hole sets for different size pools. If so you will just use a different set of holes. The arc will be different so the way the rails were set originally will not work, you will need to make an adjustment. Usually this adjustment is easy.

If you get the pool set up to be as close to 27' as possible a standard liner should fit the pool just fine.

Is it possible by removing sections and cutting the wall to convert a 21 foot pool to an 18 foot? I know it's not the same radius but I calculated that if sections are about 48" long, a slight bend of 3/4" is required per section to get the radius of an 18 foot pool.

Hi Tommy. What you are asking is very possible and I have done it many times. My method for shortening the wall is to overlap the starting point by about six inches. I then score the wall several times with a razor blade. Bending the wall back and forth a few times along the break line should snap it with a nice clean edge. I then use the existing bolt holes as a guide to drill my first set of holes. With that done I add a second row a few inches away from the first. I try to make sure both rows can be covered with the upright. With small uprights it's not always possible.

If I were doing this to a Doughboy brand pool I would order the new bottom rails. Like you said, there is a difference in arc. Doughboy parts are easy to get, and very universal, so getting the right size bottom rails would not be a problem.

There is only one brand of pool I have seen, in my 40 plus years of doing this, that did not use a different bottom rail for each size pool. There was a company that would use the same rail for the 15' and the 18', and then a different one for the 21' and the 24'. So I know what you say is possible.

Most above ground pools use the same top rails for all of their round pools. They are stamped with different hole configurations, as are the upright top caps, so each size pool uses a different set of holes. If this is not the case with yours new holes will have to be made.

Making new holes is pretty easy, the key is to make sure all of your uprights are straight up and down. Put a level on each one, set the rails in place and add new holes where needed.

The one thing you do not want to do is to use a 21' liner in your new 18' pool. I'm kidding of course, but you never know, someone might just try doing it that way.
