Is a beach entry worth it for a small child?

It is the most requested feature at that stage and the most expensive one measured in yard rather than money, because the slope has to run somewhere and on a subdivision lot that somewhere is water you could otherwise have swum in. Ask your builder to show you the surface area it consumes drawn on your own plan. Plenty of families look at that and still want it. The point is to want it with the trade in front of you.

How deep should the deep end be?

Do not take that number from any website, including this one. It depends on the whole profile of the floor, on what you intend to do from the edge, and on what the manufacturer of any equipment you are fitting specifies for their own product. Ask your builder against a drawn floor profile and insist on getting the reason along with the number.

Should we put in a diving board?

Decide at the design stage either way. A fixed board or platform shapes the deep-end floor permanently and it is close to the hardest item on the list to add afterwards, which puts it in the same decide-now category as an automatic cover. Wanting one later and having built for it is fine. Wanting one later and not having built for it is a rebuild.

Will a mostly shallow pool bore a teenager?

Less than people expect. A section held at one depth that most of the family can stand up in is where nearly every game happens, at every age, and it stays the most used water in the pool long after the children have gone. What a teenager needs on top of that is one part of the pool that is genuinely deeper and some water long enough to move through.

What can we do now that keeps our options open cheaply?

Set more deck anchors than you need so rails and ladders can be added, moved or taken out later. Run spare conduit while the ground is open. Hold the geometry simple enough that a cover stays possible. And put the part of the pool you cannot see from the house at the deep end rather than the shallow end. All four are close to free during construction and none of them are free afterwards.

How do I check what we will actually see from the kitchen?

Before the plan is final, stand at the sink and at the cooker rather than in the middle of the room, and have somebody hold a pole where the near wall of the pool will be and again where the far wall will be. Two minutes on site settles a question that no amount of looking at a plan drawn from overhead will answer, since a plan cannot show you what the coping and the deck in between are going to hide.

One Pool, Two Children, Ten Years Apart

A toddler and a teenager want opposite things from the same water. Only two of the decisions between them are permanent, and those two are rarely the ones being discussed.

By the Waukesha Pool Builders team · Published August 24, 2026

You do not design for the three-year-old and you do not design for the thirteen-year-old. You design for the passage between them, and the way to do that is to sort every idea on the table into two piles: the things that can be added, moved or taken away later, and the things cast into the floor. Almost everything anybody argues about belongs to the first pile. The arguments worth having belong to the second.

The brief, stated bluntly

A three-year-old wants to stand up, preferably everywhere, and to be inside an adult arm at all times. A thirteen-year-old wants water deep enough to jump into, long enough to move through, and a reliable absence of being watched.

Written down like that it reads as an impossible commission. It is not, because the two demands are separated by time rather than by space. The pool only has to satisfy both at once during the handful of summers when you have one of each in the water together.

Two decisions are permanent. The rest are not.

The floor profile and the sightline from the house. That is the list. Rails, ladders, the water temperature, the rules, the toys: all of that stays adjustable for the life of the pool. The shape of the floor and what you can see from the window are cast once. Spend the design meeting there.

The floor is the decision

What matters is not how deep the pool gets. It is where it changes and how abruptly. There are broadly two ways to do it and they behave completely differently with a small child in the water.

A continuous slope running from one end to the other is elegant, and it gives a child no landmark of any kind. There is nowhere to say not past here, because every point on that floor is indistinguishable from the point beside it. Adults read a slope as a gradient. A three-year-old reads it as nothing at all.

A defined break gives you a line. A section held at one constant depth, then a change, then the deeper part. A line can be taught, echoed in a colour change in the tile, marked with a rope when you want one, and pointed at from a window. It is the difference between a rule that has a location and a rule that is just a warning.

That constant-depth section is the most useful piece of water in a family pool and the only feature here that serves both stages unmodified. At three it is the place a child can stand. At eight it is where they learn to swim without being anywhere near the deep end. At thirteen it is where every game happens, because every pool game involving more than one person happens in water people can stand up in.

The number this page will not give you

Everyone arrives wanting a depth for the deep end, and no website should hand one over. It depends on the whole profile of the floor rather than one point of it, on what you intend to do from the edge, and on what any fitted equipment requires. A number produced without sight of your drawing is a guess made on your behalf.

One related item does need settling at the design stage regardless: whether there will ever be a fixed board or platform. It shapes the deep-end floor permanently and it is close to the hardest thing on this page to add afterwards. Treat it as a decide-now question in the same bracket as an automatic cover, even if the answer is no.

The sightline, which is what people actually regret

Ask which windows see the water and, more importantly, which parts of the water they see. Then go and stand where you genuinely stand: at the sink, at the cooker, in the one chair everybody uses. A room has three or four real positions and a plan drawn from above knows about none of them.

What tends to be hidden is consistent from house to house:

The near strip. The closer the pool sits to the house, the more of the near end is cut off by its own coping and the deck between. Hardest water to see, and the first water a small child reaches.
Anything behind an object. A raised wall, a spa, a planter, a shed, the housing for a cover. Each creates a blind strip that lasts the life of the pool.
The corner tucked into the house. The one you have to walk out to see.

Now the part that makes this a design principle rather than a worry. There will be a part of the pool you cannot see from the kitchen. Put it at the deep end. The invisible corner is a problem while your children are small and it becomes the most valuable corner in the yard the moment they are teenagers, for exactly the reason it worried you before. Choosing which end goes blind is free at the drawing stage and impossible afterwards.

The ten-year test

For every feature somebody is arguing about, ask three questions. Does it cost surface area permanently? Can it be added or removed later? Does it have a second life once the children are older? Anything that fails all three deserves a long conversation. Everything else deserves about a minute.

Running the test on the usual suspects

A separate shallow lobe with its own wall fails all three. Three summers of use, a permanent reduction in swimmable water, and an outline that the deck, the cover and every future idea has to work around forever.

A bench or shallow shelf at one end passes comfortably. Modest area, and its second life is as the place adults sit while children are in the water, which is a supervision position rather than a lounging one.

Rails and ladders pass so easily they barely count as decisions. They bolt into anchors set in the deck. Set more anchors than you currently need and you can add, move or remove that hardware for the next twenty years for almost nothing.

Very warm water is not a design decision at all. What suits a toddler is not what a teenager swimming lengths wants, and the difference between them is a dial rather than a shape.

A slide sized to a small child is removable and outgrown quickly, which is fine, provided nobody builds the deck around it.

The stage nobody plans for

Somewhere around nine to twelve the pool stops being a supervised activity and becomes a place they simply go. The thing to design for is the gate, which quietly becomes the piece of hardware your family touches more often than anything else you will buy for the yard. Which hand it takes, whether it stands where an adult expects it, and where the latch sits are worth a real minute of the design meeting. What that latch has to satisfy is set by your city, village or town rather than by the state or by us, so ask them and get the answer onto the drawing before anything is built.

And then they leave

The last thing worth saying is that the pool outlives both children being children. What survives is the constant-depth section, the shelf, an easy entry, and a simple geometry that never depended on anyone being small. What does not is the lobe, the outline that only made sense with a toddler in it, and the deck built around a slide.

Which is a useful way to check any plan you are handed. If it would still be a good pool with no children in the house, it is a good pool. The stage-specific parts should be the parts you could unbolt.

A consultation here ends with your lot drawn to scale, the floor profile chosen deliberately, and the sightlines checked on site instead of assumed. Households that are staging the work across a couple of seasons usually want the ways buyers pay for a pool on the table by then too. Nothing on this site carries a price, since no such data is held here. And if what suits your yard turns out to be a plainer pool than the one in your head, a drawing is the right place to have that conversation.
