Is there a standard toilet seat size?”Are toilet seats a standard size?” is a simple question with a simple response. The answer is, regrettably, no. Toilet seats, unfortunately, do not come in regular sizes. Many standard close toilets come with a round-shaped pan or D-shaped pans. Not all toilet seats fit the same? Toilet seat fittings are available in a range of designs.


Some have a bottom fix (from beneath the fixing holes).  In contrast, others are top fixing (typically necessary when access to the bottom of the pan is restricted, such as with a shrouded toilet). It is gaining popularity in most bathrooms in the UK.


Toilets can vary significantly by shape, such as square, angular, round, D-shaped and other sizes. Each toilet seat will come with its instructions. Is there a standard toilet seat size?
