Staff and patients at the Charles Ward in St Mark's Hospital in Maidenhead will make the move to Prospect Park Hospital on Thursday, January 9.
The mental health unit at the hospital in St Mark's Road will close with patients moving to two specifically designed and refitted wards at the hospital in Reading.
Berkshire Healthcare NHS Foundation Trust said the new facilities will offer single rooms with en-suite facilities and an improved outdoor space for patients.
It follows a redesign and refit of the hospital's Orchid and Rowan wards.
David Townsend, chief operations officer for the trust, said there will be a 'sensory environment' for dementia patients following a £1m grant from the Department of Health.
He added: "Only a very small proportion of people with mental health problems need a hospital stay. This move will provide those who need hospital care with the very best facilities."
A decision was made to move mental health inpatients to Prospect Park in January last year, despite an Advertiser campaign to save the ward.
Friends, family and interested parties are invited to an open day at Prospect Park on January 6.
