What do you put into a Pool community lot? I want to make a bigger one, but not overstuff it with stuff that it doesn't need. I usually just make 80-90% of the lot (20x15, for example) the pool, the rest is sand with some seats and All-In-One Bathrooms. Maybe a snowcone machine, too.
I like to have parties at the community pools, so I make sure there's a table or counter for a cake if needed, A way for sims to eat, either a mixology bar or a fridge with a sink. A block table so toddlers have something to do besides pick their nose, a hot tub, maybe a stereo.
