Tails’ Take: A Sharper, Slimmer Finish for D-Shaped Toilets

The Kartell Superslim D-shape sandwich soft-close toilet seat sits low and neatly over a compatible pan, with a straighter back, rounded front and softly finished edges creating a tailored outline rather than the bulky look of a deeper replacement seat. Its layered gloss white profile gives the toilet a crisp, furniture-like finish, while quick-release convenience and a controlled soft-close action make this an upgrade that improves both the appearance of the WC and the way it feels to use every day.

Will This Superslim Seat Follow the Shape of Your Toilet Pan?

Compare the pan outline, hinge positions and front-to-fixing measurement before ordering this replacement seat.

Who Should Buy

D-Shaped Pans Wanting a More Tailored Outline

The straighter rear and rounded front are designed to follow the general profile of a compatible D-shaped toilet pan.

Bathrooms Preferring a Lower-Profile WC

Its 40mm superslim sandwich profile gives the closed toilet a lighter and less bulky appearance.

Pans Better Suited to Fixing from Above

The top-fix arrangement suits compatible toilets where the hinges are installed through the upper surface of the pan.

× Who Shouldn’t Buy

Round Pans Without a Straight Rear Edge

A fully rounded toilet pan may not align convincingly with the seat’s D-shaped outer profile.

Fixing Holes Outside the Adjustment Range

The pan must provide suitable fixing centres between 80mm and 240mm for the hinges to be positioned correctly.

Sandwich Styling, Quick Release and Pan Measurements

What does the sandwich design change about this Kartell seat?

The sandwich format gives the closed lid and sitting section a clearly layered, closely aligned appearance. Combined with the 40mm superslim height, this creates a flatter and more streamlined profile across the top of the toilet than a thick conventional seat. The smoothed edges soften the D-shaped outline, helping the design look crisp without introducing hard or uncomfortable-looking corners.

Which measurements should I compare with my existing toilet pan?

The seat measures 425mm long and 360mm wide, with an internal opening of 290 x 230mm. Its hinge-to-front adjustment spans 410–490mm, while the fixing centres can be positioned from 80mm to 240mm apart. Compare all of these measurements with the pan rather than relying on the D-shape description alone, as similar-looking toilets can use noticeably different hinge positions and rim proportions.

How do quick release and soft close work together on this seat?

The soft-close hinges control the downward movement of the lid and sitting section, reducing the abrupt drop associated with a basic seat. Quick release allows the seat to detach from its hinge position when required, while the top-fix arrangement secures the hinges through the upper surface of a compatible pan. These features improve everyday operation, but they do not guarantee compatibility unless the seat dimensions and adjustment ranges also match the toilet.
