Pool/Spa design question

Hello all,

My name is Steve and I’m from the Inland Empire in Southern California. This is my first post, but been lurking around for a bit. I’m in the planning and design phase of my pool (owner build).

Question for everyone. My pool will be 29’x10’. With a 7’x7’ spa in the shallow end side. Initially I wanted the spa to be even (not raised) with the pool. When I was talking to someone about it, they told me during the winter months when using the spa, the cold water from the pool will seep into the spa and people in the spa will get a “jolt” of cold water. This seems logical and I didn’t think about this. Is there a way to counteract this without raising the spa?

My uncle has a spa level with his pool and I haven't noticed any cold jolts, but a raised spa will in my opinion look better and give you a slight water feature and a little noise from the falling water

My spa is level with the pool and I don't get cold jolts. Spa water tends to overflow into the pool (thanks to human bodies in the spa) rather than the other way around.

One advantage of a level spa is that you can install an auto-cover which covers both the pool and spa.

I have been in two spas now that are level-yes, the cold water got it--looks amazing though. Who is your PB? Ive seen some designs where the spa was just about 3 inches higher.

Man I was thinking about doing this myself too, but I'm in Manteca here in Central, CA, and the city is just sticklers about every single little detail almost not worth it.
