The pool is long and narrow, proportioned for swimming rather than sitting, and that governs everything else. The waterfall doesn't land in it: it spills into a separate channel that drains into the pool at one end, so the water that moves and the water you swim in aren't the same. Around it, a ring of spots recessed into the coping replaces submerged fittings, so at night what's lit is the edge and not the floor.

A high-flow pump with an adjustable nozzle generating a current you swim against without moving forward. It's what turns a short pool into one you can actually train in, and it installs both in new construction and clamped to the edge of an existing pool. Look at flow rate rather than watts, and make sure the jet is adjustable: at full power most people last only a few minutes.

With a waterfall running it stops being a luxury: aeration raises pH daily, and correcting by hand becomes a weekly chore. Budget for replacing the probe every one or two seasons and for calibrating it at the start of each summer, which is what most people skip and why it stops reading true.

What to check on the datasheet is the slip classification: a pool surround calls for the high class, and interior porcelain with a similar look doesn't meet it. The pale tone isn't only aesthetic: dark paving under August sun is simply impossible to walk on without shoes.

In a long pool surrounded by large-leaved planting it's the difference between five minutes and half an hour each time. Choose one that climbs the walls and does the waterline, because on pale mosaic the dirty band at the edge shows long before any dirt on the floor does.
See similar on Amazon(paid link)A flush in-ground point, walkable and rated for a wet zone, washing the paving rather than aiming at the pool. It sits in the coping itself, spread around the whole perimeter, and its job is to mark where the floor ends. Check two things on the datasheet: that it's rated for foot traffic and that it's suitable for a pool splash zone, which is a step above an ordinary garden recessed fitting.
