Modern Bathroom Design

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.

Installation Flexibility

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.

Everyday Comfort

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.

Water Efficiency

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.

Dual flush toilet water efficiency feature
Optional Upgrade

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.

Note: To achieve a 6-star rating, this toilet must be installed with the optional Drainwave unit. If purchased as the toilet suite only, it carries a 4-star rating. Always confirm trap type, set-out, inlet position, and installation requirements before purchase.

Buying Guide

Shipping

Delivery timeframes, order processing, pickup and delivery charges — everything about getting your order to you.

Last updated 15 July 2026

Free shipping to Greater Sydney, online orders
0–3 days to process and dispatch your order
2–7 days metro delivery after dispatch

01 Free shipping

  • Free shipping to Greater Sydney on online orders only.
  • Large or bulky items to other regions require a freight quote. Start a Live Chat (chat icon, bottom right) and we'll quote it for you.

02 Standard delivery timeframes

Destination Delivery time after dispatch
Metro areas (all states) 2–7 business days
Regional areas (all states) 7–15 business days
Timeframes are estimates counted in business days from the date of dispatch, not from the date of order. The actual delivery time depends on the courier carrying your parcel.

03 Order processing & delays

  • You'll receive an Order Confirmation Email as soon as your order goes through.
  • Please allow 0–3 business days for processing — in most cases we dispatch within the first 24 hours.
  • Once your order ships, we'll email you the tracking information.

Some delays sit outside our control:

  • Public holidays, peak periods and sale periods add time. During Christmas and major sales, please allow extra.
  • High order volumes may occasionally extend the timeframe slightly.
Remote areas: all courier networks have limits. For some remote postcodes couriers will not deliver to the door — your parcel goes to a local depot or Australia Post outlet, and you'll be notified to collect it.

04 Additional delivery charges

Charges beyond the base delivery fee may apply where:

  • Stair or lift access is needed — if the delivery point isn't directly accessible, or goods must be carried up stairs, this adds labour and time.
  • The location is difficult to reach, or two or more people are needed to deliver safely.
These are assessed case by case, quoted and agreed with you before we proceed, and billed on a separate invoice. No surprises.

05 Missed deliveries

  • If nobody is available at the delivery address during the agreed window, a re-delivery fee may apply.
  • Any extra charge will be communicated and agreed with you before a second attempt.
  • Please make sure you or an authorised person is present at the agreed time.

06 Pick up

  • We'll get your order ready as soon as possible and email you a notification with your booking number and collection details.
  • Please wait for that email before coming in.

Back to Wall Toilet Suites FAQs

Is a back to wall toilet better?

Yes, a back to wall loo is often considered better for modern homes due to its sleek, space-saving design and easy-to-clean surface. A back to wall wc conceals plumbing for a tidy look and offers improved hygiene with fewer crevices where dirt can collect. Many back-to-wall toilets for sale at MyHomeware also support efficient tornado or vortex flushing systems, making them both stylish and practical.

How to install a back to wall toilet?

Typically, you can follow these steps to install a back-to-wall toilet:
Check Set-Out: Measure the rough-in distance (e.g., 100–220mm for S-trap or 180mm for P-trap) to match your toilet model.
Position the Pan: Align the toilet pan flush against the wall, ensuring the back to wall toilet bowl sits level.
Connect the Trap: Fit the S- or P-trap using the adjustable connector (cut if needed).
Attach the Cistern: Secure the cistern to the wall and connect the water inlet (top, bottom, or back entry).
Seal and Test: Seal around the base with silicone, turn on the water, and test for leaks.
Note: The back to wall loo installation involves careful planning and measurements, and a professional installation is highly advised.

How to maintain a back-to-wall toilet for longevity?

To maintain your back-to-wall toilet for longevity:

  • Clean regularly using non-abrasive cleaners to protect glazed surfaces.
  • Use a rimless-safe brush to avoid scratching the back to wall toilet bowl.
  • Wipe down external surfaces to prevent dust buildup in tight gaps.
  • Check inlet and flush valves annually for wear.
  • Avoid harsh chemicals that can damage seals or soft-close seats.

Do back to wall toilets save space?

Yes, back to wall WCs are ideal for smaller bathrooms as the concealed cistern and compact design reduce visual clutter and maximise usable space, making the room feel more open.
