Who it suits

Is the Modern Lap right for you?

Built for people who swim for exercise. Forty feet gives you real strokes between turns, and the narrow 10 ft width keeps the build focused on length instead of surface area you will not use. Triathletes, retirees keeping up a morning routine and anyone recovering with low-impact exercise tend to get the most out of it.

The clean rectangle and dark water fit modern, mid-century and desert-modern homes with flat roofs and big glass. It also works for owners who want the pool to read as an architectural line in the yard rather than a play area.

How much yard it needs

Because it is long and skinny, this design fits lots where a wider pool will not. Running it parallel to the back fence, the depth needed is about 10 ft of water plus roughly 4 ft of deck on either side plus a 5 ft gap to the back fence, or about 23 ft. You also need about 50 ft of width (40 ft of pool plus 5 ft on each end). Turned to run away from the house, the numbers swap. A builder checks the real lot lines and slope before anything is final.

Spa, shelf and seating options

The raised spa sits at one end, which doubles as a turn wall and keeps the swimming lane clear. A bench along one long wall is a common add for cooling down after laps. Sun shelves and wide entries tend to eat into lane length, so most lap owners skip them or use recessed steps tucked into a corner.

Looking after it

Dark plaster looks stunning, but it shows white calcium scale and etching more than light finishes, so water balance matters. It also absorbs sun and runs warmer. On a 40 ft run, make sure your robotic or suction cleaner is rated to cover the full length, and plan a cover if you want to cut evaporation. Compare the shorter Grecian if you want a geometric pool with more play room.

What the build involves

Digging a long, slim trench is quick, but spoil hauling and access matter on narrow lots. Lap pools are also sensitive to level, since any tilt shows along a 40 ft waterline, so the builder sets the bond beam carefully.

Modern Lap FAQ

Modern Lap questions.

Didn't find yours? Send us a message or email [email protected]. A real person answers.

Is 40 feet long enough for real lap swimming?

For most recreational swimmers, yes. It is shorter than a competition pool, so you turn more often, but it allows a steady stroke rhythm. The length can be adjusted in the designer.

Should I add a swim jet instead of a longer pool?

A current system lets you swim in place in a shorter pool. Many owners with this design choose the length instead because it feels like open swimming.

Why does a lap pool look so dark?

The default Midnight finish is a dark gray plaster that turns the water deep blue. You can switch to a lighter finish in the designer if you prefer bright water.
