Travel toilet/shower bench

Hey everyone. I'm trying to work out the best option for bathroom equipment for travel. I use a commode at home, but it's too big for travel. I'm thinking a stool/bench with a a cutout for digital tiolet access might be the way to go (manual daily morning bowel routine). Then can transfer back and move it over to shower and back on. But this type of thing doesn't seem that common? Something like this is what I'm thinking https://melrosewheelchairs.co.nz/parts_accessories/shower_benches.html With cutout to use on toilet also.

What do you think? Any tips? Or anything else you would recommend?

Thanks in advance 🙏
