My routine for quarantine in my small 2bd apt is as follows:
Quarantined animal lives in the bedroom. I have clothes for the day set out in the living room in advance, deal with quarantined critter first thing in the morning then shower and get dressed. Deal with snake room after showering and getting dressed. Go to work and go about my day. Come home and deal with snake room as needed. Quarantine room/bedroom is dealt with last thing of the day when I am sure I don't need to go back in the snake room. Basically treat either side of your room as two completely different spaces as far apart as possible. Separate set of cleaning bottles, separate snake hook, separate feeding tongs, separate roll of paper towels, separate everything.
I wouldn't bring this animal home until you're sure you've got tub temps and quarantine routine dialed in. I use a CHE above my quarantine tub for ambient temps and my room is 73*. I think you'll melt the lid trying to use that set up for ambients in a low 60s basement.
Not the ideal quarantine scenario, but it could work if you're very diligent.
