"We've had a fantastic response," said site manager Alex Lawson. "It is being used on a daily basis, with customers returning time and time again, and planning trips with a stop scheduled here, knowing they can safely use the toilets with dignity, from 6am-11pm, seven days a week.
"We have worked hard to let people know about it, with a media campaign for the unveiling, detailing it on our website, and very obvious signage on our roadside totem pole."
Cornwall Services is the only non-motorway service station in the UK to offer a Changing Places facility. Visitors who need to use it just ask a member of staff.
The wheelchair-accessible room is 7.5m2, with an adult-sized, height adjustable changing bench and ceiling track hoist.
