Pubs are continuing to count the cost after two weeks of heavy rain.
The Fat Fowl in Bradford on Avon is expected to be closed for several months.
Owner Mark Kendall, who has run the bar and restaurant for eight years with his wife Arlene Caddow, said two foot of water on Christmas Eve ruined everything.
"You work really hard for eight years and its all literally washed away in two hours. We stood there on Christmas Eve in two foot of water and had no choice but to walk out and lock the door behind us."
Mr Kendall said all of the floors had to be replaced, along with the bar, wall paneling and most of the fridges.
The Fat Fowl had to cancel all of its bookings over Christmas and New Year, and has now cancelled all functions in January and February.
All 15 members of part time staff have been told to find alternative employment while the venue is closed.
The Trinity pub, on James Street West, was forced to close for a third time in two weeks because of flooding.
The pub closed over Christmas and again New Year's Eve because its cellar and toilets flooded.
Manager Michelle Spence said more than three feet of water had come into the pub from nearby storm drains.
The pub had started repair work but heavy rain at the weekend led to more flooding.
"We had repaired the doors down stairs but that's all been ruined again. Luckily we didn't lose any stock this time just a day's takings but we are starting to lose the goodwill of our customers."
The Bathampton Mill also remains closed two weeks after the River Avon flooded the pub on Christmas Eve.
Heavy rain left the pub surrounded by several feet of water, filling the cellar and damaging equipment in the kitchens.
Staff had to be rescued by Avon Fire and Rescue Christmas Eve and the pub cancelled all of its Christmas Day and Boxing Day bookings.
Sally Ellison, spokesman for Mitchells and Butlers, which owns the pub, said the continuing bad weather had prevented repair work from starting.
"We are closed until further notice following more heavy rain fall in the last few days and we are waiting for the water levels to subside.
"We are working with our contractors to start repairs to the building as soon as possible so we can get the restaurant open and trading again as soon as we can."
The Canal and River Trust have confirmed no boats have sunk along the River Avon in Bath and the Kennet and Avon canal remains open through the city despite high water levels.
The Trust said five boats in the Hanham area had either lost their moorings or were under water, where water levels have risen to 14 feet.
