## Description

Product Description

Review: Terrific Toilet Seat - Took ages to find a square toilet seat that would fit our RAK Ceramic Toilet. didn't know if it would be the right shape but took a chance and so glad I did. Perfect size shape and super build quality. The soft close action is a bonus and works for both the seat and the lid...no more waking the family in the middle of the night. Comes with comprehensive instructions and 2 sets of installation screws that work with both normal and close coupled toilet basins. HIGHLY recommend this product
Review: Good quality slow closer - A good quality, robust toilet seat with slow closing seat and cover. I would say it was worth at least 4.5 stars as it does looks good in situe and is also easy to fit and remove. The only bugbear that I have is that the securing screws need frequent tightening. I am tightening it up sufficiently and it stays solidly in position for about a week before it needs re-tightening. Note that this may not be the case for everyone. The ceramic toilet base upper surface isn’t exactly going to grip the underside of the seat supports so it tends to slide over time after frequent use, slowly loosening the screws that hold the seat in place.

## Features

- Perfect Fit for D-Shaped Pans: Fits UK standard D-shaped pans only with 135–175mm hole distance (adjustable hinges). Dimensions: 460mm (lid) / 445–450mm (seat) length × 360mm width. (Lid slightly longer as it overlaps the seat — please check your pan’s size before purchase.)
- Easy Top-Fix Installation (5–10 mins): Designed for a firm grip and user convenience. Simple top-fixing system means no need to reach under the pan.
- Quick-Release for Hygiene: Press the quick-release button to easily remove the seat for deep cleaning — ensuring better hygiene and reduced bacteria buildup.
- Soft-Close Comfort: Enjoy a smooth, noiseless close every time. The sturdy, soft-close mechanism prevents slamming — perfect for quiet nights.
- Durable Urea-Formaldehyde Material: High-quality, stain- and scratch-resistant surface that won’t fade over time. Four integrated non-slip buffers keep the seat stable with no wobbling.
- In the Box: 1 × D-Shaped White Toilet Seat, 1 × Top Fixing Accessories Set, 1 × User Manual.

### ⭐⭐⭐⭐⭐ Simple to fit and stylish
*by B***N on 20 April 2026*

I remember spending far too long lying uncomfortably on a bathroom floor trying to secure traditional toilet fittings, only to have the seat move again or be misaligned. This system is a total contrast - simple to do and the seat was replaced in 10 minutes. It is also good to know that if I have aligned it badly, it is very easy to take the seat off and adjust. Brilliant. Also will be much easier to clean. Sadly, the first seat supplied was faulty - the release mechanism wouldn't release - but the Amazon return system worked well and the perfect replacement arrived two days later. So I highly recommend both the product and the customer service.
