floor surface, I would go for ceramic or stone tile with underfloor heating.
as for equipment.
metcal soldering station
huntron tracker
logic analyser
ghz range digital oscilloscope
spectrum analyser
3d printer
did I miss anything? :-?
For the decorum, I would go with the "Frankenstein's lab" look, although the jacob's ladders could be a problem if you do RF work. ;D
