Are Back to Wall Toilets a Good Idea?
Back to wall toilets offer a sleek, modern design that maximizes bathroom space and simplifies maintenance. In this blog post, we explore the pros and cons of back to wall...
Cal Back to Wall Toilet Suite
The Cal back to wall toilet suite combines clean modern lines with concealed plumbing fittings for a streamlined bathroom finish. Designed for flexible replacement projects, it features a gloss white vitreous china body, quick release heavy duty soft-close seat, back left inlet, and S-Trap or P-Trap installation options.

Clean Back to Wall Profile
The Cal toilet suite features a sleek back to wall design that sits neatly against the wall, helping conceal plumbing fittings for a cleaner and more refined bathroom appearance.
Its simple lines and gloss white finish make it suitable for a wide range of Australian bathroom renovations, from contemporary homes to practical replacement projects.

Default S-Trap or Optional P-Trap Available
This toilet suite is available as either a S-Trap or P-Trap model, with the default S-Trap option suitable for a 65-180mm set-out. The variable connector bend provides greater flexibility when matching existing plumbing positions.
The back left inlet configuration is designed for installations where the water connection is positioned to suit concealed or rear inlet setups.

Quick Release Heavy Duty Soft-Close Seat
The included Duraplas soft-close seat is designed for improved durability, scratch resistance, and quiet everyday use. The soft-close function helps reduce slamming, making it practical for family bathrooms and shared spaces.
The quick release design also allows easier removal during cleaning, helping maintain a more hygienic toilet area with less effort.

Dual Flush Performance
The Cal toilet suite uses a dual flush system with 3L per half flush, 4.5L per full flush, and 3.4L per average flush. If purchased alone, the toilet suite carries a 4 star rating.
When installed with the optional Drainwave unit, the toilet can achieve a 6 star rating, making it a strong option for water-conscious bathroom upgrades.

Drainwave Sewer Doing Unit
The optional Drainwave Sewer Doing Unit is designed to accelerate waste through the drain line, helping prevent waste build-up and dry drains. It is especially useful when paired with ultra low dual flush toilets and other water-efficient plumbing fixtures.
Constructed from PVC, the Drainwave can serve up to 6 toilets and supports a maximum 6m horizontal distance between the unit and the furthermost toilet.
