A man who visited a public toilet at a Colwyn Bay shopping centre saw a head appear under a cubicle divider, a court heard.
Lawrence West, unemployed, of Cynfran Road, Llysfaen, admitted observing a private act for sexual gratification.
Magistrates at Llandudno imposed an 18 months community order with rehabilitation and a period of trail monitoring using an electronic tag. He was also fined £80 and ordered to pay £100 compensation for distress and £180 costs.
West must register as a sex offender for five years.
Defence solicitor Alex Fitzgerald said West was aged 59 and seemed lonely.
Prosecutor Sarah Marsh said he had a caution for a similar offence.
