Is it haram to intentionally delay salat but still pray on time?

Assalaamu ‘Alaikum Wa Rahmatullahi Wa Barakatuh fellow Muslims.

The reason I ask is that I find it convenient that if I’m not in a state of wuddu—let’s say around Zuhr time—I wait until Asr is near. That way, I can make wuddu once, pray Zuhr, and shortly after, pray Asr, minimizing the number of times I need to make wuddu.

It also simplifies things because when I urinate, I often get a couple of droplets on my underwear. This approach means I don’t have to change my underwear as often.
