The Tewkesbury Park hotel, golf and country club in Gloucestershire has completed the first part of an interior refurbishment costing £2.5m.
The hotel's pool and leisure complex has also been transformed including the installation of underfloor heating in the changing rooms, a new steam room and an outdoor hot tub.
Work has been carried out as part of the planned refurbishment by new owners the McIntosh family, who took over the hotel in April 2014 from Washington Hotels.
Managing director Chris McIntosh and sister Claire White, said they plan to provide the long-term investment needed to revitalise the property.
They have brought in Focus Hotels Management on a long-term contract.
Claire White, director of Tewkesbury Park said: "We're thrilled with the results of this major improvements programme, which has created significantly more comfortable and contemporary facilities for our guests."
She added: "Very little money had been spent on the hotel before we acquired it, so there was a need for some significant investment in renovation and refurbishment. We want to take the hotel into a fresh new era and we're confident that Tewkesbury Park now offers guests some of the finest facilities in the county."
The hotel also plans to create nine additional superior rooms - including two bridal suites - in the original part of the former 18th century manor house which offers views over 163 acres of parkland.
This work is expected to be completed by the autumn with redecoration of the hotel's reception area, cocktail bar and event rooms following in the winter.
Tewkesbury Park opened in 1976 and has an 18-hole golf course.
