Toilet seats vary dramatically in both shape and size, and the idea that one fits all certainly does not apply! However, choosing the right toilet seat when you are armed with the right information is simple. Named aptly due to their shape, D-Shaped toilet seats are designed to be used with D-Shaped toilet pans. For an ideal fit, it is best to measure the width of your toilet pan at its widest point and the length from the fixing holes to the edge of the pan, then choose a seat in proportion. D Shape soft close toilet seats are not only stylish, they provide maximum comfort. We have a wide range of soft close D-Shaped toilet seats in stock from low priced replacements, modern hygienic easy clean rimless seats, to luxury high end exquisite designer D shape toilet seats that incorporate the latest in technology and come with a sleek control panel.
