Seeking Recommendations for Space-Saving Dimmers and Switches

I’m in the process of upgrading my home’s lighting system and I’m looking for some advice on selecting the right dimmers and switches. I’ve got some metal switch boxes installed, but they’re quite small—only about 3 inches by 3 inches by 1.5 inches. I need to install 3-way switches, which complicates things a bit.

My concern is whether I can install in-wall modules without having to add each light switch individually. The space in these boxes is so limited, and I don’t want to end up with a cluttered setup. I’ve heard about some space-saving options out there, but I’m not sure which ones would work best for my situation.

Has anyone else dealt with this kind of challenge? I’d love to hear about your experiences and any recommendations you might have. Whether it’s specific product suggestions or just general advice on how to approach this, I’d really appreciate it! Let’s see if we can figure this out together. :blush:
