Up to £100,000 will be spent sprucing up two toilets in the House of Lords, it has been revealed.
The restroom in the Palace of Westminster - which hasn't been refurbished for 20 years - is, according to the contract for the job, in an "unacceptable condition for the high profile area they are in".
Work listed in the contract includes installing "historic oak panelling to meet English Heritage requirements", minor demolition work, new decorations and new sanitary equipment.
The work is expected to start in August and last six weeks. The palace is Grade I listed, and so all work has to be done in line with English Heritage requirements.
Twelve companies have expressed an interest in carrying out the work, with the contract valued at between £90,000 and £100,000.
A House of Lords spokesman said: "The House of Lords has opened a procurement process to refurbish two toilets on the principal floor to ensure we comply with disability access legislation.
"As with all procurement we undertake this will be done with a determined focus on value for money for the taxpayer."
The tender document states: "The toilets are principally used for members and VIP guests of the Palace of Westminster.
"The lavatories are in an unacceptable condition for the high profile area they are in and they give a poor image of the Palace of Westminster. A refurbishment is required urgently to bring the amenities to a standard that reflects a World Heritage site."
