Close-coupled, back-to-wall, wall-faced, smart toilets and bidet seats — styles, costs and cleaning.
Cost estimates only: Any building or upgrade figures in this guide are indicative, not fixed prices or quotes. Costs and inclusions vary by project, supplier, location and time. Confirm current written prices and specifications directly with your builder, suppliers and relevant trades.
- Wall-faced toilets create a premium, seamless look with no visible cistern or pipework
- Smart toilets and bidet seats offer wash, dry and deodorise functions — increasingly popular
- Back-to-wall toilets are a mid-range option — clean look without the complexity of wall-faced
- Toilet rough-in position must be planned during pre-construction — especially for wall-faced models
- Consider a bidet rough-in (power point near the toilet) even if you don't install a bidet initially
Toilet selection might seem straightforward, but there are several styles and an increasing range of premium options including smart toilets and bidet seats. The style you choose affects the bathroom's look, cleaning ease and functionality. Understanding the options helps you make the right choice.
Toilet Styles
- Close-coupled — the cistern sits directly on top of the pan; the most common and affordable style; visible pipework at the back; standard inclusion in most homes
- Back-to-wall — the pan sits flush against the wall; cistern is visible but pipework is concealed; cleaner look than close-coupled; mid-range cost
- Wall-faced (concealed cistern) — the pan sits flush against the wall and the cistern is concealed inside the wall; premium, seamless look; no visible pipework; requires wall plumbing; more expensive
- Wall-hung — the pan is mounted to the wall with no floor contact; cistern concealed in wall; ultra-modern look; makes floor cleaning easy; requires structural wall support; most expensive
Watch Out
Smart Toilets & Bidet Seats
Smart toilets and bidet seats are becoming increasingly popular in Australian homes. They offer wash (bidet) functions, heated seats, warm air drying, automatic flushing and deodorising. Some are standalone smart toilet units; others are bidet seats that replace the seat on a standard toilet.
- Standalone smart toilet — integrated unit with all functions built in; premium; expensive ($1,000–$5,000+)
- Bidet seat — replaces the standard seat on a close-coupled or back-to-wall toilet; more affordable ($500–$1,500); requires a power point near the toilet
- Functions — warm water wash, adjustable spray position, heated seat, warm air dry, night light, automatic flush, deodoriser
- Rough-in — even if you don't install a bidet initially, consider adding a power point near each toilet for future installation
Cleaning Considerations
Toilet style affects cleaning ease. Close-coupled toilets have visible pipework at the back that collects dust and is awkward to clean. Back-to-wall and wall-faced toilets eliminate this gap, making cleaning much easier. Wall-hung toilets are the easiest to clean — the floor is completely clear underneath. If cleaning ease is a priority, consider upgrading from close-coupled to back-to-wall or wall-faced.
| Upgrade | Example Cost |
|---|---|
| Back-to-wall toilet (vs close-coupled) | $100–$300 |
| Wall-faced toilet (vs close-coupled) | $200–$600 |
| Wall-hung toilet (vs close-coupled) | $400–$1,000 + wall carrier |
| Bidet seat (add to existing toilet) | $500–$1,500 |
| Smart toilet (standalone unit) | $1,000–$5,000+ |
| Power point near toilet (for bidet) | $70–$150 (at electrical appointment) |
- What toilet style does the builder include as standard — close-coupled, back-to-wall, or wall-faced?
- Can I upgrade to a wall-faced toilet, and does it require concealed cistern plumbing?
- Can I add a power point near the toilet for a future bidet seat?
- Does the builder offer smart toilets or bidet seats, and what's the cost?
- Wanting a wall-faced or wall-hung toilet but not planning the concealed cistern during pre-construction
- Forgetting a power point near the toilet — can't install a bidet seat later without expensive electrical work
- Choosing close-coupled toilets where cleaning ease is a priority — visible pipework collects dust
- Not considering a bidet rough-in even if you don't install a bidet initially — future-proofs the bathroom
- Wall-faced and wall-hung toilets require a concealed cistern — plan it during pre-construction
- Add a power point near each toilet at the electrical appointment — enables a future bidet seat
- Back-to-wall toilets offer a cleaner look than close-coupled without the complexity of wall-faced
- A bidet seat ($500–$1,500) is a more affordable alternative to a full smart toilet ($1,000–$5,000+)
