Dimensions
Your toilet bowl – well mounted or traditional – can fit with the bidet seat if it is plain and round/oval and if dimensions A, B and C match following :

• 140 ≤ A ≤ 200mm
• 420 ≤ B < 440mm select the standard model
• 440 ≤ B ≤ 480mm select the elongated model
• C ≥ 40mm

The Arrow E-LOO is designed to fit standard U.K. and European toilet dimensions, both round and elongated. And it is designed to fit better because the water tank is mounted behind the seat, not on the side like other models sold in the U.K. and Europe. Installation is in four simple and straightforward steps.
