What is a D shape bidet seat - and do you need one?

Walk into any modern Australian bathroom built or renovated in the last decade and you are likely looking at a D-shaped toilet. The bowl has a flat or gently squared front edge rather than a full oval curve - a design shift driven by the global move toward contemporary square-edged bathroom aesthetics.

A D shape bidet seat is engineered to match this geometry exactly. The front edge of the seat follows the flat profile of the bowl, sitting flush without gaps or overhanging edges. Fitting an O shape (round) bidet seat to a D shape toilet creates poor alignment, visible gaps at the front, and - critically - potential nozzle positioning errors that reduce cleaning effectiveness.

The Conor Elara is specifically designed for the D shape profile common in modern Australian homes. It replaces your existing toilet seat entirely, and its geometry is purpose-built for the square-front toilets now found in most new builds and renovated bathrooms across Australia.

Watermark certification: why it matters for every Australian buyer

Watermark is the national certification scheme administered by the Australian Building Codes Board (ABCB). Under the National Construction Code and state plumbing regulations, any product that connects to the potable water supply must carry Watermark certification before it can be legally installed in an Australian home or rental property. This is not a voluntary quality mark - it is a legal requirement.

An uncertified bidet seat connected to your water supply is technically non-compliant with Australian plumbing standards - which can affect home insurance, rental compliance, and property resale. The Watermark certification on the Conor Elara distinguishes it from a large portion of the sub-$200 bidet seat market.

Non-electric vs electric: which is right for your bathroom?

The Australian bidet market spans from $25 attachments to $2,000+ smart toilets. Here is how the Conor Elara compares across the key segments:

Duroplast vs standard plastic: the material difference that matters

Most toilet seats sold in Australia under $100 are made from polypropylene (PP) - prone to yellowing, surface scratching, and structural fatigue. The Conor Elara uses Duroplast (urea-formaldehyde, UF) - a thermoset resin used in premium European and Australian-specification toilet seats for decades.

• No yellowing: Duroplast maintains colour indefinitely. Standard PP seats visibly discolour within 2–5 years.
• Surface hardness: Resists scratching and porosity, reducing bacterial adhesion and improving cleanability.
• Chemical resistance: Compatible with bleach-based cleaners without surface degradation.
• 150kg load capacity: Structural rigidity that standard PP seats at this price cannot match.
• Thermal stability: Does not soften or deform under high ambient temperature - relevant in QLD, WA, and NT.
  

Soft-closing seat and cover: the daily quality-of-life upgrade

The soft-close mechanism uses a hydraulic damper in the hinge to slow the descent of both the seat and lid. The lid-slam is one of the most common sources of household bathroom noise and one of the most frequent causes of hinge damage over time. A soft-close mechanism eliminates both - extending product life and removing a daily household frustration. It is particularly valued in households with children, elderly users, or light sleepers.

Step-by-Step Installation Overview

1.  Shut off the water supply

Turn the shutoff valve behind or beneath the toilet clockwise to close. Flush to drain the cistern. 60 seconds.

2.  Remove the existing toilet seat

Unscrew the two mounting bolts holding your current seat to the bowl. Lift clear and set aside.

3.  Install the T-valve

Disconnect the existing supply hose from the cistern. Thread the T-valve between the supply valve and the hose. Hand-tighten only.

4.  Mount the fixing plate

Position the fixing plate over the toilet mounting holes. Insert bolts and plug nuts. Tighten with the included wrench.

5.  Connect the flexible hose

Connect the hose from the T-valve outlet to the bidet seat water inlet. Hand-tighten at both ends. Confirm left or right inlet matches your variant.

6.  Slide seat on and restore water

Slide the bidet seat onto the fixing plate until it clicks. Open the shutoff valve slowly. Check for leaks. Done.

The environmental case for a non-electric bidet seat

A non-electric bidet seat requires no electricity, uses approximately 500–600 mL of water per wash cycle (a fraction of a standard flush), and significantly reduces toilet paper consumption. Australia imports over 72,000 tonnes of pre-converted toilet paper annually - volumes that have grown nearly 32% in a single year. A household reducing toilet paper use by 70–80% through bidet use makes a measurable environmental contribution.
