42″ vs 48″ Panels: What to Know When Selecting a Wall Height for Your New Pool

When it comes to designing your pool, there are a couple key factors that you have to decide on while choosing your pool kit. One of those key factors is how high you’d like your wall panels to be; 42” or 48”? To help you decide what’s best for your pool needs we’ll cover the main differences between the two heights here!

42” PANELS come standard in our pool kits. This wall height creates a traditional 3’4” shallow end depth which is typically preferred for younger children or inexperienced swimmers. Based on the pool bottom of your choice, there could be a steeper drop off between the shallow and deep end of your pool.

48” PANELS are more popular with older kids and adults as this height provides a deeper shallow end depth of 3’10”; perfect for pool sports, such as volleyball or water polo! The 48” panel also creates a deep end with a less significant slope transition and is safer for diving pools.


In the diagram below, the 42″ panel is depicted by the dotted line and the 48″ panel is depicted by the solid line.


The 48″ panel offers a more ideal water level so that standing in the shallow end is an enjoyable hangout area for adults while 42” offers a safer swimming area for small children on inexperience swimmers.

Due to the 6″ of added depth, you can see that the slope leading to the hopper (deep end bottom) is more gradual than in a 42″ wall pool. Therefore, the 48” panel provides a safer diving pool by providing additional space for a diver to arc and surface with less risk of running into the bottom of the pool.


While the panels are 42” and 48” in length, this will not be the final depth of your shallow end. Keep in mind that 2” of those panels will be covered by your pool base pre-mix and your water line typically falls between 4-6 inches below the top of your panel. Therefore, your shallow end’s final depth will be as follows:

  • 42” panel = shallow end a depth of 34”-36”
  • 48” panel = shallow end a depth of 40”-42”

Overall, there is no right or wrong answer when choosing the size of your wall panels. Here are some questions to ask that may help make the best decision based off of the intended use of your pool!

  • Who will be using this pool?
    • Younger/Inexperienced Swimmers? – 42” is more ideal
    • Teenagers/Adults/Sports Lovers? – 48” is more ideal
  • Will you want to be able to play pool water sports?
    • 48” is preferable for most water sports
  • Do you want a diving board?
    • 48” is the safer option for divers


Regardless of the size of the wall panels you decide for your pool, always remember to have safety first in mind especially with children and family pets.

    Another method to achieve a deeper shallow area is by creating a cove area in the shallow end. You could take a standard 42″ wall, then add a small 6″ x 6″ cove. By doing this, you would have the same depth as a standard 48″ wall panel pool would have and save money in the process!

    How is the cove achieved or added?

  3. Greg says:

    The cove-method is a very easy way to achieve a deeper shallow end or deeper flat bottom with a 42″ panel. Instead of the pool bottom being completely flat, there will be a cove that is basically a slope away from the wall down to the shallow-end depth or flat bottom depth. Length of the cove will depend how deep you would like the shallow end or flat bottom. The only other consideration when choosing to cove the shallow end for a deeper shallow end is that you will need to also shape a “ramp” in front of the step so there is something to step onto when you get in the pool.

    I agree with johnny, as 48″ wall is more expensive and this is not for small children, if we use 42″ wall and then add a small 6″x6″ cove. this will work same as 48″ wall and also less expensive.

  5. The details which you have shared with us about the pools wall size is really good to read these blog.
