The Gustavsberg Nautic 1591 toilet seat is specially designed to make it easier to replace an old toilet seat with a new one. The large base covers the traces of the old seat, and the 32 mm hole in the base allows for the installation of a washbasin drain pipe. The seat also fits well in corners thanks to its compact dimensions and rounded tank.

The toilet seat has an open S-lock, a drain connection on the right and a 4/2 litre Duo flush. The glazed, open flush rim ensures easy cleaning, and the effective flush extends to the top of the bowl, improving hygiene. The seat height is 420 mm, and it can be attached to the floor either with screws or glue. The quiet water filling and minimalist design increase comfort and make the seat a stylish choice.
