“We moved to a new build house where these toilets were installed as standard. I have had to replace all of the loo seats, some more than once as they split across the seat. There are no generic seats that I can find that fit the pan as Roca have a unique shape and locating holes that are different to anyone else's. They are also very expensive for what they are.”
Splitting is a common issue with many seats. Roca offers a 2 year warranty on their seat, which is above the standard one year warranty provided by most others.
