Patients could have a hot meals service cut back and see car park charges introduced in a bid to cut a £5m deficit in an NHS trust's budget.
Norfolk and Waveney Mental Health Partnership NHS Trust has already saved £50,000 by changing a laundry contract.
It is now considering bringing in parking fees at its sites across Norfolk and North Suffolk.
There are also plans to cut patient hot meals to just one a day in summer and axe an in-house hairdresser.
Other patient services will also face review and their free newspapers will be withdrawn.
The trust provides specialist mental health services for 800,000 people and employs more than 2,000 staff.
A trust spokesman has said that by changing or stopping some areas it is hoped to reduce the impact of cuts in clinical services.
