I’ll be honest, my regret wasn’t something flashy either. It was underestimating how loud and visible equipment would feel once everything looked brand new.
We upgraded finishes, coping, lighting, all the fun stuff. But I left the equipment pad basically where it was and didn’t screen it or rethink layout. Once the yard looked clean and modern, that old pad suddenly stuck out. The pump noise wasn’t terrible, but when everything else feels polished, you notice it more. I eventually added a simple privacy screen and rerouted a bit of plumbing to clean up the look, which I should’ve planned from day one.
Second thing I’d rethink is deck pitch around seating areas. The main drainage away from the pool is fine, but I didn’t pay enough attention to where water runs after splash out. After a high bather load weekend, water would track toward one corner near our chairs. It dried, but it meant moving furniture more often than I’d like.
On the water side, I also didn’t anticipate how much startup chemistry would matter with a new surface. The first month I was chasing pH drift more than expected and watching the saturation index closely so I didn’t mess up the finish. Not a disaster, just more hands-on than I imagined.
If you’re still planning, I’d zoom out and think about daily annoyances. Noise, drainage, circulation patterns, shade at different times of day. The cosmetic stuff is exciting, but the tiny functional details are what you’ll either appreciate or regret every single week after it’s done.
