let me know the brand and model number.


Yes, use two timer switches on the same Hot circuit from a
single breaker. That way either switch, or both switches, can
be on and 'ticking'. You must make sure that the same hot
(black) and neutral (white) supplies both switches. The output
of both switches connect to the light fixture 'hot' side.



Or a motion sensor


That will work as described, but if timer A is ON it won't let a
conciencious tenant turn the lights OFF from the timer B locatiuon,
would it?

That's probably better than leaving the light on "forever", so if you
can live with that minor inconsistancy, do so.

I agree that a motion detector is the better way to go.

If the laundry room is small enough you can probably get by with just
one near the center of the ceiling.

You could then remove the existing swiches, splice the switch wiring
appropriately, put blank covers where the switches were, and Bob's yer
uncle.
